In this sustainable approach, first of all, microcrystalline cellulose and biochar were successfully obtained from this natural source and functionalized using an easy, eco‐friendly, and one‐step synthesis by employing proper precursors and nanomaterials, that is, (3‐mercaptopropyl)trimethoxysilane, (3‐glycidyloxypropyl)trimethoxysilane, citric acid, β‐Cyclodextrins, and halloysite nanotubes, to prepare green, hybrid, and cross‐linked systems featuring tailored properties. The obtained derivatives were characterized and employed for the further development of eco‐friendly and sustainable poly(vinyl alcohol) nanofiber composites through the electrospinning technique on nonwoven glass microfiber support. After thermal treatment, the membranes displayed enhanced mechanical tensile properties and were tested in a dead‐end filtration cell for the removal of a methylene blue and methyl orange mixed solution, in particular demonstrating high retention and separation performances toward the cationic methylene blue dye. Among all, the PVA@MCC_GPTMS_HNT and PVA@MCC membranes achieved methylene blue retention rates of 93.4% and 79.9%, methylene blue/methyl orange separation efficiencies of 93.5% and 82.1%, and fluxes of 133.7 and 501.7 L m^−2  h^−1, respectively. Moreover, a biochar‐supported nano zero‐valent iron composite was obtained and tested for the removal of MB in batch experiments. The Langmuir adsorption isotherm model better describes its sorption behavior with a maximum sorption capacity of 305.65 mg g^1. journalArticle original public Article A1 inpress accepted-for-publication ugent Giulia Rando Giulia Rando aut author 979609074826 Silvia Sfameni Silvia Sfameni aut author Jozefien Geltmeyer Jozefien Geltmeyer aut author 000070582957 975000449525 0000-0002-1281-2968 Alessandra Palella Alessandra Palella aut author Lorenzo Spadaro Lorenzo Spadaro aut author Alberto Riminucci Alberto Riminucci aut author Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Maria Rosaria Plutino Maria Rosaria Plutino aut author Department of Materials, Textiles and Chemical Engineering TW11 sht department 01B03115 86318f8f-a91a-4be9-a7d9-5ced53ff78bf 2015-06-01 2018-05-31 05V01710 31bd61c9-f74f-4eed-a08e-1075e52e9b15 2010-01-01 2015-08-31 2575-0356 2026 e70321 2026 Technology and Engineering biochar cyclodextrins electrospun nanofiber halloysite microcrystalline cellulose water filtration POLY(VINYL ALCOHOL) PVA METHYLENE-BLUE MICROCRYSTALLINE CELLULOSE REMOVAL ADSORPTION BIOCHAR NANOCRYSTALS KINETICS DYES NANOPARTICLES info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01KMFZPAJRCBT6C4PPHQC68C4J/file/01KMG00W15HB55PGPYZ6J4Q8SY info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 7979963 bytes Energy Environ Materials - 2026 - Rando - Nanofiber PVA‐Based Membranes Incorporating Functionalized Spanish Broom.pdf https://biblio.ugent.be/publication/01KMFZPAJRCBT6C4PPHQC68C4J/file/01KMG029HD8FFH16RH2HBRSKA5 info:eu-repo/semantics/closedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 11217446 bytes EEM-2025-0822.R2_Proof_fl.pdf Rando, Giulia, Silvia Sfameni, Jozefien Geltmeyer, Alessandra Palella, Lorenzo Spadaro, Alberto Riminucci, Karen De Clerck, and Maria Rosaria Plutino. 2026. “Nanofiber PVA-Based Membranes Incorporating Functionalized Spanish Broom Derivatives for Sustainable Water Purification.” ENERGY & ENVIRONMENTAL MATERIALS. doi:10.1002/eem2.70321.

A promising strategy involves modulating radiative heat transfer by dynamically adjusting surface emissivity, thereby facilitating reversible switching between heat-retentive and heat-dissipative states. Existing systems enable emissivity switching but often need external energy or lack dimensional stability when deformed, which limits wearable applications. Here, a fully passive, autonomously adaptive dynamic emissivity switch textile (DEST) based on a thermo- and humidity-responsive electrospun poly(N-isopropyl acrylamide) (PNIPAM) copolymer is introduced. To ensure robust functionality in humid or aqueous environments, a crosslinkable allyl-functionalized PNIPAM copolymer is synthesized via post-polymerization amidation of a P(NIPAM-co-methyl acrylate) copolymer and processed using a green water-ethanol-based electrospinning technique. Thiol-ene crosslinking produced water-stable, thermoresponsive nanofibers with a transition near skin temperature. For reversible macropore actuation, a dimensionally stable architecture is employed that avoids out-of-plane distortion, achieved through a honeycomb-shaped electrospinning collector and a tailored mechanical cutting pattern. A silver coating imparts the overall infrared (IR) reflectivity, facilitating radiative heat retention when the macropores are closed. The resulting DEST exhibits dual responsiveness to temperature and ambient humidity, enabling passive switching between emissive and reflective states without external energy input, with a approximate to 6 degrees C reversible thermal comfort window. journalArticle original public Article A1 published published ugent Eva Loccufier Eva Loccufier aut author 802002671374 974161061035 0000-0001-7045-2721 TW11 Muluneh G.

In vertebrates, they are housed in organelles called melanosomes that typically vary in shape from spherical to rod-like, but can also adopt unusual morphologies, such as flatness or hollowness. For over 50 years, it was thought that melanosome hollowness occurred only in birds and always alongside elongation, where hollow rods or platelets form organized nanostructures that produce brilliant iridescent colours. Here, we present the first description of hollow, spherical melanosomes in mammals, from the hairs of the platypus (Monotremata: Ornithorhynchus anatinus). By contrast, we found no evidence of hollow melanosomes in the other two monotreme genera or in any other mammal so far examined (from a combined dataset of 126 species encompassing 103 genera). These spherical, hollow platypus melanosomes are unique among vertebrates and, surprisingly, only produce brown coloration, suggesting a potential function unrelated to colour or a non-adaptive origin. This finding provides exciting new avenues of research into mammal melanogenesis and the evolution of melanosomes. journalArticle original public Article A1 published published ugent Jessica Leigh Dobson Jessica Leigh Dobson aut author 000211829610 802004043825 979522896891 WE11 Frane Babarović Frane Babarović aut author 802004343111 977776651866 WE11 Wanjie Xie Wanjie Xie aut author 802003945411 WE11 Michaël Nicolaï Michaël Nicolaï aut author 802002891545 974799314567 0000-0002-9570-0311 WE11 Gerben Debruyn Gerben Debruyn aut author 802003560037 976557705309 WE11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Matthew Shawkey Matthew Shawkey aut author 802002093216 979048085026 0000-0002-5131-8209 WE11 Liliana D'Alba Altamirano Liliana D'Alba Altamirano aut author 802002269634 0000-0002-2478-3455 WE11 Department of Biology WE11 sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department 41K07823 3d62d395-b5d6-4a31-8a48-1cbb69868e8d 2023-08-15 2026-03-14 3G0E8322 5b87ab1d-40ba-4a79-8a95-e3bba2da8200 2022-01-01 2024-12-31 1219525N c8a6e6db-45ab-11ef-b6a0-49d99dda6551 2024-11-01 2027-10-31 01P10922 bc94ffbb-34cb-11ed-8ff4-732a3d2b012f 2023-02-14 2025-04-30 41D02319 e4b73a54-e13d-46ea-8057-2cea52799ca2 2019-06-01 2023-05-31 41U06724 371fd6e9-0b57-449e-bcbf-4794fea6ba00 2024-04-10 2027-04-09 1744-9561 1744-957X 2026 22 3 20250721 2026 Biology and Life Sciences melanin hollow melanosomes mammal coloration platypus hair nanostructure EVOLUTION MELANIN PATTERNS info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01KMZG561X37GQ17AX82D5SX3H/file/01KMZG8CQ34M8W2ZC27TTQWPVM info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 3395965 bytes rsbl.2025.0721.pdf Dobson, Jessica Leigh, Frane Babarović, Wanjie Xie, Michaël Nicolaï, Gerben Debruyn, Karen De Clerck, Matthew Shawkey, and Liliana D’Alba Altamirano. 2026. “A Unique Hollow Melanosome Morphology in the Hairs of the Platypus Ornithorhynchus Anatinus.” BIOLOGY LETTERS 22 (3). doi:10.1098/rsbl.2025.0721.

Here, we show that temperature-resistant, stable hydrophobic organosilica nanofiber membranes combined with salting-out enable gravity-driven liquid-liquid separation without external pressure or energy input. We develop a fast pre-functionalization method by sol-gel synthesis of tetraethoxy silane (TEOS) with dimethyldiethoxy silane (DMDES), and compare the performance with a TEOS-based membrane post-functionalized with chloro-octyldimethylsilane (Cl-OdMS). Both membranes show long-term hydrophobic stability (water contact angle >110° for over three months when submerged in water) and robustness against high temperature and alkaline conditions. The membranes act as phase separators that reproduce equilibrium binodal compositions, rather than selective barriers. By exploiting the salting-out effect, the immiscibility window of alcohol/water mixtures was expanded, enabling separation even for fully miscible ethanol/water systems, with K2CO3 the most effective salt. Approximately 97% of added salt remained in the water-rich phase. Separation is also successful for ternary water/ethanol/alcohol mixtures, allowing construction of binodal solubility curves. This work demonstrates an energy-efficient, chemically and thermally robust membrane-based approach for alcohol/water separation in chemical processes. journalArticle original public Article A1 published published ugent Sofie Verschraegen Sofie Verschraegen aut author 000150868746 802003501534 919029486586 0000-0002-6164-3662 TW11 Bianca Swanckaert Bianca Swanckaert aut author 978889457589 0000-0001-6036-6512 Eva Loccufier Eva Loccufier aut author 802002671374 0000-0001-7045-2721 TW11 Dagmar D'hooge Dagmar D'hooge aut author 802000024082 0000-0001-9663-9893 TW11 Klaartje De Buysser Klaartje De Buysser aut author 801001571962 0000-0001-7462-2484 WE06 Karen De Clerck Karen De Clerck aut author 801000947425 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Chemistry WE06 sht department 3F006621 190fbf11-2a82-11ec-95aa-05ef7abe0c3c 2021-11-01 2025-10-31 3S039119 9cfd7b5f-f96d-11e9-b85e-e128f57a36f9 2019-11-01 2023-10-31 01J10219 1e0c3a2d-9d90-11e9-83f9-d13d95d2d7be 2019-10-01 2024-07-30 1383-5866 1873-3794 2026 382 5 136093 2026 Technology and Engineering Chemistry Organosilica nanofiber membranes Functionalized membranes (ternary) alcohol/water separation Wettability Salting-out SALTING-OUT WATER OIL/WATER SILICA WETTABILITY POLYMERIZATION EXTRACTION MECHANISM SOLVENTS RECOVERY info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01KAK0QTRC86HRW240M0K5SZN2/file/01KCTYQB0XRZ0PDTBFPV2BJPH5 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1676361 bytes accepted_manuscript.pdf https://biblio.ugent.be/publication/01KAK0QTRC86HRW240M0K5SZN2/file/01KCTYR4WEWMF6FC2N3S4J1W9H info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 6743402 bytes publisher_version.pdf https://biblio.ugent.be/publication/01KAK0QTRC86HRW240M0K5SZN2/file/01KCTYRCY2YECABAWYMV7TBBNE info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf dataset http://purl.org/dc/dcmitype/Dataset 761611 bytes supplementary_material.pdf Verschraegen, Sofie, Bianca Swanckaert, Eva Loccufier, Dagmar D’hooge, Klaartje De Buysser, and Karen De Clerck. 2026. “Long-Term Hydrophobic Organosilica Nanofiber Membranes for Gravity-Driven Alcohol/Water Separation.” SEPARATION AND PURIFICATION TECHNOLOGY 382 (5). doi:10.1016/j.seppur.2025.136093.

Three synthesis methods — phase inversion, electrospinning, and stretching — were evaluated, each impacting the membrane morphology differently. The polymer selection influenced porosity, wettability, and surface free energy with PTFE exhibiting the highest hydrophobicity. Membrane wettability was assessed using the ionic liquid [P6,6,6,14][N(Tf)2] as the selective extractant, revealing that larger pore sizes enhanced the impregnation efficiency, while reducing the final SLM stability. Solute fluxes and selectivity were quantified; electrospun membranes exhibited higher fluxes, ranging from 1.0 to 1.2 g/(m2h) for MBA, 2.1 to 2.2 g/(m2h) for MPPA, and 0.8 to 1.2 g/(m2h) for IPA, along with a higher selectivity compared to phase inversion membranes, with fluxes ranging from 0.2 to 0.3 g/(m2h) for MBA, 0.2 g/(m2h) for MPPA, and 0.3 to 0.4 g/(m2h) for IPA. Stretched membranes demonstrated a comparable selectivity (MBA/IPA = 2.2, MPPA/IPA = 3.9), but reduced fluxes with increasing pore size, decreasing from 2.7 to 0.5 g/(m2h) for MBA, 4.9 to 0.9 g/(m2h) for MPPA, and 1.2 to 0.3 g/(m2h) for IPA, as the nominal pore size increased from 50 to 450 nm. This phenomenon likely resulted from the improved impregnation efficiency, coupled with a lower porosity and larger thickness in the membranes with larger pores. Overall, the membrane morphology significantly influenced the SLM performance and stability, with homogeneous, porous membranes possessing smaller pore sizes and high hydrophobicity exhibiting optimal characteristics. These findings underscore the critical role of membrane structure and properties in SLM applications. journalArticle original public Article A1 published published ugent Gilles Van Eygen Gilles Van Eygen aut author Stijn Keuppens Stijn Keuppens aut author Xander De Breuck Xander De Breuck aut author Bianca Swanckaert Bianca Swanckaert aut author 978889457589 0000-0001-6036-6512 Patrik Boura Patrik Boura aut author Eva Loccufier Eva Loccufier aut author 802002671374 974161061035 0000-0001-7045-2721 TW11 Juraj Kosek Juraj Kosek aut author Deepika Ramasamy Deepika Ramasamy aut author Fady Nahra Fady Nahra aut author 802002268220 0000-0002-1115-9725 WE06 Anita Buekenhoudt Anita Buekenhoudt aut author Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Bart Van der Bruggen Bart Van der Bruggen aut author Patricia Luis Patricia Luis aut author Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Chemistry WE06 sht department 3S039119 9cfd7b5f-f96d-11e9-b85e-e128f57a36f9 2019-11-01 2023-10-31 01J10219 1e0c3a2d-9d90-11e9-83f9-d13d95d2d7be 2019-10-01 2024-07-30 1383-5866 1873-3794 2025 352 128192 2025 Technology and Engineering Polymers Supported liquid membranes Extraction technology IONIC LIQUID SEPARATION STABILITY info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01HZEYNB2HRCKDYC2R1AR7QSJP/file/01HZEZ004MCSNDPSQWECJA4TDV info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 2619639 bytes 1-s2.0-S1383586624019312-main.pdf https://biblio.ugent.be/publication/01HZEYNB2HRCKDYC2R1AR7QSJP/file/01HZH56HS807SKSQCKXT48JA1V info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 495370 bytes Final manuscript - ACCEPTED.pdf Van Eygen, Gilles, Stijn Keuppens, Xander De Breuck, Bianca Swanckaert, Patrik Boura, Eva Loccufier, Juraj Kosek, Deepika Ramasamy, Fady Nahra, Anita Buekenhoudt, Karen De Clerck, Bart Van der Bruggen, and Patricia Luis. 2025. “Comparison of Distinctive Polymeric Membrane Structures as Support Materials for Membrane Extraction of Chiral Amines.” SEPARATION AND PURIFICATION TECHNOLOGY 352. doi:10.1016/j.seppur.2024.128192.

This work focuses on the design and development of sustainable bio-polymeric blends based on polyamide 11 (PA11) employed to produce different Electrospun Nanofiber Membranes (ENMs) through the electrospinning process. Moreover, different eco-friendly functional nanofillers based on hybrid halloysite (HNT) derivatives were employed as dopant agents of the starting polymeric blends in a ratio of 1, 2 and 5 wt% of PA11 to achieve better mechanical and thermal features as well as retention performances of specific wastewater organic contaminants. Chemical-physical and structural-morphological characterizations, concerning all the nanofillers and the obtained sustainable membranes, are reported as well as the removal and separation studies of two selected anionic and cationic dyes, methyl orange (MO) and methylene blue (MB) in a dead-end filtration apparatus. The newly developed composite ENMs, compared to pristine PA11 ones, show good tensile mechanical and thermal properties, and increased MO and MB removal rates, modulated by the different HNT derivatives employed. Dead-end filtration experiments were performed using 1 and 3 layers of each type of ENM revealing, for 1-layer PA11 ENMs containing HNT modified with octadecylphosphonic acid and (3-aminopropyl)triethoxysilane (PA11@C18_HNT_NH2) and dimethyloctadecyl[3(trimethoxysilyl)propyl]ammoniumchloride (PA11@HNT_N + C18), a selectivity towards the removal of the cationic dye MB with a separation efficiency of 69.8 and 73.3 % respectively. Hence, 3-layer PA11 ENMs doped with HNT functionalized with (3-aminopropyl)triethoxysilane (PA11@HNT_NH2) display the highest retention rate for MO and MB respectively of 100 and 89.8 %. journalArticle original public Article A1 published published ugent Giulia Rando Giulia Rando aut author 979609074826 Jozefien Geltmeyer Jozefien Geltmeyer aut author 000070582957 975000449525 0000-0002-1281-2968 Silvia Sfameni Silvia Sfameni aut author Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Maria Rosaria Plutino Maria Rosaria Plutino aut author Department of Materials, Textiles and Chemical Engineering TW11 sht department 2214-9937 2025 44 e01402 2025 Technology and Engineering Hybrid nanomaterials Halloysite Sol-gel polyamide11 Electrospinning Filtration membranes Environmental remediation HALLOYSITE NANOTUBES NANOCOMPOSITES PROGRESS REMOVAL SOLVENT info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01JSXVZBNGDM4GJ5XANRJESTKK/file/01JSXX4GT1FAZX23WEN9CFCSE8 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 18077334 bytes 1-s2.0-S2214993725001708-main.pdf Rando, Giulia, Jozefien Geltmeyer, Silvia Sfameni, Karen De Clerck, and Maria Rosaria Plutino. 2025. “Sustainable Functional Electrospun Polyamide 11/Halloysite Derivatives Nanofibrous Membranes for Water Treatment Applications.” SUSTAINABLE MATERIALS AND TECHNOLOGIES 44. doi:10.1016/j.susmat.2025.e01402.

This review explores cutting-edge pathways for textile waste management, spotlighting innovations that reduce reliance on incineration and landfilling while driving material circularity. It highlights advancements in collection, sorting, and pretreatment technologies, as well as both established and emerging recycling methods. Smart collection systems utilizing tags and sensors show great promise in streamlining logistics by automating pick-up routes and transactions. For sorting, automated technologies like near-infrared and hyperspectral imaging lead the way in accurate and scalable fiber separation. Automated disassembly techniques are effective at removing problematic elements, though other pretreatments, such as color and finish removal, still need to be customized for specific waste streams. Mechanical fiber recycling is ideal for textiles with strong mechanical properties but has limitations, particularly with blended fabrics, and cannot be repeated endlessly. Polymer recycling—through melting or dissolving waste polymers—produces higher-quality recycled materials but comes with high energy and solvent demands. Chemical recycling, especially solvolysis and pyrolysis, excels at breaking down synthetic polymers like polyester, with the potential to yield virgin-quality monomers. Meanwhile, biological methods, though still in their infancy, show promise for recycling natural fibers like cotton and wool. When other methods are not viable, gasification can be used to convert waste into synthesis gas. The review concludes that the future of sustainable textile recycling hinges on integrating automated sorting systems and advancing solvent-based and chemical recycling technologies. These innovations, supported by eco-design principles, progressive policies, and industry collaboration, are essential to building a resilient, circular textile economy. journalArticle review public Review A1 published published ugent Mehrdad Seifali Abbasabadi Mehrdad Seifali Abbasabadi aut author Brecht Tomme Brecht Tomme aut author 000120101558 802003221547 975685845663 0000-0001-7765-3059 TW11 Bahman Goshayeshi Bahman Goshayeshi aut author 000181667357 802003352697 974415920754 0000-0001-8723-5045 TW11 Oleksii Mynko Oleksii Mynko aut author 000181441732 802003445051 977343596578 TW11 Yihan Wang Yihan Wang aut author 000220483424 802004089901 974661454329 0000-0003-1628-5736 TW11 Sangram Roy Sangram Roy aut author 971014451965 UGent Rohit Kumar Rohit Kumar Rohit Kumar Rohit Kumar aut author 979793490317 0000-0002-9586-0542 UGent Bhargav Baruah Bhargav Baruah aut author 802004068780 979970365369 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Steven De Meester Steven De Meester aut author 802000481497 973680737243 0000-0002-5246-3918 LA24 Dagmar D'hooge Dagmar D'hooge aut author 802000024082 973689492909 0000-0001-9663-9893 TW11 Kevin Van Geem Kevin Van Geem aut author 801001595406 919019785576 973254481958 0000-0003-4191-4960 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Green Chemistry and Technology LA24 sht department 179K07820 0b43d7a4-035a-4c97-b5ba-1ddd11ab3ad9 2020-03-01 2021-11-30 41G04520 527cc4f4-c741-4619-835d-363131255a24 2020-01-01 2024-05-31 41A06719 308c7104-dad2-4160-a94f-2724d65f23ca 2019-09-01 2025-02-28 G065324N 56969f61-abeb-11ee-93fb-0db84e20c636 2024-01-01 2027-12-31 41D08919 33e5665e-f621-4479-9128-81922feec34f 2019-06-01 2022-09-30 2073-4360 2025 17 5 628 2025 Technology and Engineering textile waste end of life sustainability reuse mechanical recycling chemical recycling info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01JYJZAKHK63JM8GSSH1WYG37F/file/01JYK02ADH0PVZKE6MWM9A0212 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 14063427 bytes polymers-17-00628-v2.pdf Seifali Abbasabadi, Mehrdad, Brecht Tomme, Bahman Goshayeshi, Oleksii Mynko, Yihan Wang, Sangram Roy, Rohit Kumar Rohit Kumar, Bhargav Baruah, Karen De Clerck, Steven De Meester, Dagmar D’hooge, and Kevin Van Geem. 2025. “Advancing Textile Waste Recycling : Challenges and Opportunities across Polymer and Non-Polymer Fiber Types.” POLYMERS 17 (5). doi:10.3390/polym17050628.

Reptile eggshells serve as compelling models for tunable bioinspired material design due to their diversity in forms and functions. This study presents a modular approach to designing keratin-based composites with customizable vapor sorption behavior. Inspired by reptile eggshells, four key biomimetic components were reconstructed: (1) electrospun keratin membranes resembling the fibrous shell membrane, (2) an egg protein matrix replicating the proteinaceous eggshell matrix, (3) calcium carbonate (CaCO3) particles introducing mineralization, and (4) a paraffin coating representing the lipid-rich cuticle layer. The modular accuracy of these biomimetic models was validated by comparison with representative reptile eggshells through Scanning Electron Microscopy analysis and Fourier-Transform Infrared Spectroscopy. Dynamic Vapor Sorption (DVS) analysis confirmed that varying the CaCO3 content allows precise control over the absorption profiles, ranging from low to high sorption values. Additionally, integrating the organic matrix and lipid coating enabled fine-tuning of the sorption properties. The resulting biomimetic composites exhibited sorption characteristics comparable to those of natural eggshells, including Caiman crocodilus (low absorption) and Pantherophis guttatus (high absorption), demonstrating the effectiveness of the modular design strategy. These findings establish a foundation for engineering advanced biocompatible materials with adaptable sorption behavior, offering potential applications in moisture-regulating wound dressings, tissue engineering scaffolds, sustainable packaging, and filtration systems. journalArticle original public Article A1 published published ugent Yana Maudens Yana Maudens aut author 000180496485 802004439404 973207706538 0009-0004-7574-7309 TW11 Gerben Debruyn Gerben Debruyn aut author 802003560037 976557705309 WE11 Eva Loccufier Eva Loccufier aut author 802002671374 974161061035 0000-0001-7045-2721 TW11 Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Erica Savino Erica Savino aut author Cinzia Tonetti Cinzia Tonetti aut author Claudia Vineis Claudia Vineis aut author Alessio Varesano Alessio Varesano aut author Matthew Shawkey Matthew Shawkey aut author 802002093216 979048085026 0000-0002-5131-8209 WE11 Liliana D'Alba Altamirano Liliana D'Alba Altamirano aut author 802002269634 0000-0002-2478-3455 WE11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Biology WE11 sht department 3G0A7921 ae3ff06f-4420-11eb-809b-01df1efbbcb6 2021-01-01 2024-12-31 41J09123 42855afe-0cd7-424d-872c-55a9c8b61592 2023-08-15 2026-08-14 2590-0064 2025 33 102032 2025 Technology and Engineering Modular biomimetic composites Protein nanofibers Keratin electrospinning Tunable vapor sorption Reptile eggshells CALCIUM-CARBONATE WATER RELATIONS CUTICLE NANOFIBERS ARAGONITE EXCHANGE LIZARD VAPOR info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01JZHTVH49RDCBMYYFDVQK615P/file/01JZQ516RSFPM4E5GAASQRRBZ3 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 9989893 bytes 1-s2.0-S2590006425006027-main.pdf Maudens, Yana, Gerben Debruyn, Eva Loccufier, Lode Daelemans, Erica Savino, Cinzia Tonetti, Claudia Vineis, Alessio Varesano, Matthew Shawkey, Liliana D’Alba Altamirano, and Karen De Clerck. 2025. “Modular Design of Biomimetic Electrospun Keratin Composites for Tunable Gaseous Sorption Inspired by Reptile Eggshells.” MATERIALS TODAY BIO 33. doi:10.1016/j.mtbio.2025.102032.

Research has primarily been focused on the interface strength under shear loading, while studies on interface strength under normal loading are limited. Nevertheless, normal loading is very relevant, for example to understand failure mechanisms in 90 degrees plies. Therefore, in this work, we modified a single fiber composite test to a cruciform shape with a thinned middle section to test glass fiber matrix interface properties under normal loading conditions. These specimens allow testing the interface up till the point of failure of the polymer matrix, thus improving over regular cruciform specimens. An in-house designed tensile stage enabled the use of in -situ transmission and reflection microscopy. Insights into the debonding process were obtained over a large fiber length (+/- 10 mm) via the use of a step-and-shoot method. The methodology is applied to a glass fiber with an epoxy compatible and incompatible sizing. It shows that the debonding process can be divided into two partially independent debonding processes (initiation and propagation). The obtained data enabled the construction of a descriptive function for the total debond length of a fiber-matrix interface. This showed that besides a high interface strength, a homogeneous application of the sizing should be aimed to decrease the chances of initiating debonding at lower stresses. journalArticle original public Article A1 published published ugent Olivier Verschatse Olivier Verschatse aut author 974442908376 0000-0001-7732-6007 Mehdi Nikforooz Mehdi Nikforooz aut author 976302603389 UGent Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department BOF/24J/2023/006 958ee467-1003-11ee-a391-81a6d079669c 2023-10-01 2027-09-30 BOF/STA/202009/046 25182d45-ccf4-11eb-9f0b-e5cd0f711fbd 2021-07-01 2025-06-30 0266-3538 1879-1050 2025 263 111089 2025 Technology and Engineering Cruciform Fiber-matrix interaction Debonding Glass fiber POLYMER MATRIX PULL-OUT MECHANICAL-PROPERTIES EPOXY INTERFACE MICROBOND TEST STRENGTH TENSILE FRAGMENTATION STRESSES BEHAVIOR info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01JS1WW95JRMG3FSS5TMFF9R9T/file/01JSHKJ973SSBAX2ED0GH44222 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1668413 bytes Final rev1.pdf https://biblio.ugent.be/publication/01JS1WW95JRMG3FSS5TMFF9R9T/file/01JT39AQCFFNBR7RKA5V25VHMD info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 7808366 bytes Publisher_version.pdf Verschatse, Olivier, Mehdi Nikforooz, Karen De Clerck, Wim Van Paepegem, and Lode Daelemans. 2025. “Analysis of Fiber-Matrix Interface Debonding under Normal Loading Using in-Situ Microscopy and Cruciform-Shaped Single Glass Fiber Composite Specimens.” COMPOSITES SCIENCE AND TECHNOLOGY 263. doi:10.1016/j.compscitech.2025.111089.

Physical and chemical incorporation of responsive chromophores into different polymers results in the fabrication of chromic polymers. Chromic electrospun nanofibers are prepared using the electrospinning technique, and their stimuli-responsivity is improved due to their high surface-to-volume ratio. This Perspective focuses on recent studies and developments on stimuli-induced chromic electrospun nanofibers. Within this Perspective, these nanofibers are divided into different classes of photochromic, thermochromic, electrochromic, mechanochromic, halochromic, solvatochromic, hydrochromic, and ionochromic according to the stimuli to which they respond. In addition, the preparation methods, chromic compounds, electrospinning conditions, response mechanisms, and different applications of chromic nanofibers will be discussed. The main applications of such chromic nanofibers are food packaging sensors, health monitoring sensors, anticounterfeiting materials, ink-free rewritable media, and smart clothing. Several new strategies are also proposed for different applications in future studies. The preparation of multiresponsive nanofibers that combine different chromic properties in a single system and also multifunctional nanofibers that merge stimuli-responsive chromic properties with other smart functionalities can be considered in the future. This Perspective aims to assist researchers and scientists in the preparation and development of new multifunctional chromic electrospun nanofibers for advanced applications, including multimode anticounterfeiting materials, multiresponsive sensors for food packaging, and shape memory-assisted dual-mode encryption of important data. journalArticle review public Review A1 published published ugent Donya Razzaghi Donya Razzaghi aut author Milad Babazadeh-Mamaqani Milad Babazadeh-Mamaqani aut author Amin Babaie Amin Babaie aut author Fatemeh Esmati Fatemeh Esmati aut author Hossein Roghani-Mamaqani Hossein Roghani-Mamaqani aut author Mostafa Rezaei Mostafa Rezaei aut author Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Richard Hoogenboom Richard Hoogenboom aut author 802000620432 975196852903 0000-0001-7398-2058 WE07 Department of Organic and Macromolecular Chemistry WE07 sht department 1944-8244 1944-8252 2025 17 3 4247 4289 2025 Chemistry Smart materials Chromic polymers Electrospinning Chromic nanofibers Electrospun nanofibers Smart applications ELECTROCHROMIC PROPERTIES COLORIMETRIC SENSOR WO3 FIBERS FILMS MEMBRANES FABRICATION BEHAVIOR FACILE STRIPS info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01JNZN61RAM5T1F38ZS3YXH2X6/file/01JNZQ2SN6QKKQSEGQZEM8RY0R info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 3774641 bytes Stimuli-Chromic Nanofibers Ed_author version.pdf https://biblio.ugent.be/publication/01JNZN61RAM5T1F38ZS3YXH2X6/file/01JSKG7TQC1AR8KG05NB8BG6S6 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 7685091 bytes razzaghi-et-al-2025-chromic-electrospun-polymer-nanofibers-preparation-applications-and-the-future.pdf Razzaghi, Donya, Milad Babazadeh-Mamaqani, Amin Babaie, Fatemeh Esmati, Hossein Roghani-Mamaqani, Mostafa Rezaei, Karen De Clerck, and Richard Hoogenboom. 2025. “Chromic Electrospun Polymer Nanofibers : Preparation, Applications, and the Future.” ACS APPLIED MATERIALS & INTERFACES 17 (3): 4247–4289. doi:10.1021/acsami.4c17105.

In this study, the effect of hydrothermal ageing for different time periods was examined on the tensile strength of E-glass fibres and the interfacial properties of E-glass/epoxy in quasi-static and fatigue loading. For this purpose, single fibre tensile tests, single fibre fragmentation tests and single short fibre composite tests were performed. In particular, quasistatic and fatigue tests were conducted on innovative single short fibre composite specimens to capture the initiation and propagation of debonding cracks. Consequently, hydrothermal ageing had an insignificant effect on the interfacial strength of E-glass/epoxy, whereas it resulted in a detrimental impact on the mixed mode debonding propagation. In this regard, as the fibre off-axis angle approached 90 degrees, substantially longer debonding cracks were captured in aged E-glass/epoxy specimens compared to virgin E-glass/epoxy specimens in both quasi-static and fatigue loading. journalArticle original public Article A1 published published ugent Mehdi Nikforooz Mehdi Nikforooz aut author 976302603389 UGent Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Flanders Make FlandersMake sht department BOF/STA/202009/046 25182d45-ccf4-11eb-9f0b-e5cd0f711fbd 2021-07-01 2025-06-30 01J10219 1e0c3a2d-9d90-11e9-83f9-d13d95d2d7be 2019-10-01 2024-07-30 01B03518 320e7057-5b7c-11e9-ac93-1bffacd2a7e2 2018-06-01 2020-05-31 BOF/24J/2023/006 958ee467-1003-11ee-a391-81a6d079669c 2023-10-01 2027-09-30 160A08923 548bb758-1ab6-4d6d-893a-6f0a6cbbb94a 2023-11-01 2026-10-31 1359-8368 1879-1069 2025 304 112649 2025 Technology and Engineering Polymer-matrix composites (PMCs) Debonding Optical microscopy physical methods of analysis Fractography CARBON-FIBER SINGLE-FIBER COMPOSITES STRENGTH DEGRADATION ADHESION WATER info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01KDHZGMEZ1DCARCVJ2BPVHZB2/file/01KDJ0RPETEYDKWX39VBTY9A1B info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 290990 bytes manuscript_AAM.pdf https://biblio.ugent.be/publication/01KDHZGMEZ1DCARCVJ2BPVHZB2/file/01KF3PMJRTJXVSNJW9836APKJ7 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 15719113 bytes Publisher_version.pdf Nikforooz, Mehdi, Lode Daelemans, Karen De Clerck, and Wim Van Paepegem. 2025. “The Effect of Hydrothermal Ageing on the Interfacial Bonding of E-Glass Fibre/Epoxy in Quasi-Static and Fatigue Loading.” COMPOSITES PART B-ENGINEERING 304. doi:10.1016/j.compositesb.2025.112649.

Further, their dielectric response can potentially be further modified by infiltrating a second phase such as a polymer to produce thin film nanocomposite dielectrics. Despite their potential, uptake of mesoporous silica thin films has been hindered by difficulties in controlling the nanoscale structure and silica texture. We employ advanced characterization and kinetic Monte Carlo modeling to identify critical synthesis parameters governing the mesoporous silica texture. Different degrees of pore ordering can be achieved from quasi-random to highly ordered, eliminating the trial-and-error typically associated with achieving a targeted nanostructure. We then infiltrate semicrystalline poly(vinylidene fluoride) and polypropylene into the sub-10 nm pores to completely suppress the formation of crystalline domains in the polymers and produce nanocomposite dielectrics. Polypropylene nanocomposite dielectrics exhibit dielectric constants similar to 20% higher than silica and 125% greater than those of polypropylene. Poly(vinylidene fluoride) nanocomposites exhibit relaxor ferroelectric behavior. These dielectric materials are enabled by controlled, hierarchical design that spans the self-assembly of the silica matrix, tuning of the pore surface chemistry, and modification of the polymer conformations through the resulting quasi-3D nanoconfinement. We believe that these nanocomposites represent a powerful platform for the study of polymers under extreme levels of confinement, as well as a potential platform for next-generation dielectric materials. journalArticle original public Article A1 published published ugent Sofie Verschraegen Sofie Verschraegen aut author 000150868746 802003501534 919029486586 975200255882 0000-0002-6164-3662 TW11 David W.

Shelled eggs are key components of animal reproduction on land, evolving independently in distant lineages of terrestrial animals including nematodes, gastropods, annelids, arthropods and chordates. They regulate critical functions such as the exchange of gases between embryo and the environment, desiccation avoidance and protection from harmful radiation, microbial infection and mechanical damage. A core mechanism behind eggshell multifunctionality is the incorporation of minerals (mainly calcium carbonate and calcium phosphate) into the shell. Very little is known about eggshell structure in invertebrates, but some recent pioneer studies have proposed that similar mineralization patterns may have evolved convergently in eggshells of vertebrates, pulmonate gastropods, and stick insects. However, because a detailed characterization of the structural and chemical composition of invertebrate eggshells is not available, it has not been possible to test this hypothesis. Here, we use computed tomography, electron microscopy, electron backscatter diffraction analyses, atomic force microscopy, spectroscopy and histochemistry to characterize and compare microstructure and chemical composition of snails, insect and vertebrate eggshells. These techniques revealed the universal presence of an organic matrix in mineralized eggshells. However, disparities in the distribution of calcium throughout the shell, crystallographic orientation that appears random in invertebrates (but not vertebrates), and presence of different calcium types including the rare and unstable vaterite highlight divergence whose functional significance should be the subject of future study journalArticle original public Article A1 published published ugent Gerben Debruyn Gerben Debruyn aut author 802003560037 976557705309 WE11 Seung Choi Seung Choi aut author Jessica Leigh Dobson Jessica Leigh Dobson aut author 000211829610 802004043825 979522896891 WE11 Yana Maudens Yana Maudens aut author 000180496485 802004439404 973207706538 0009-0004-7574-7309 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Matthew Shawkey Matthew Shawkey aut author 802002093216 979048085026 0000-0002-5131-8209 WE11 Shukang Zhang Shukang Zhang aut author Liliana D'Alba Altamirano Liliana D'Alba Altamirano aut author 802002269634 0000-0002-2478-3455 WE11 Department of Biology WE11 sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department 3G0A7921 ae3ff06f-4420-11eb-809b-01df1efbbcb6 2021-01-01 2024-12-31 41K07823 3d62d395-b5d6-4a31-8a48-1cbb69868e8d 2023-08-15 2026-03-14 41J09123 42855afe-0cd7-424d-872c-55a9c8b61592 2023-08-15 2026-08-14 1359-6640 1364-5498 2025 261 212 230 2025 Technology and Engineering AMORPHOUS CALCIUM-CARBONATE EGG-CAPSULES MATRIX ULTRASTRUCTURE ARCHITECTURE MEMBRANES PROTEINS CHORION MODEL LAYER info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01JQRG2BWC5BBKN9AJXKAKMY3E/file/01JQRG68CCTJ61N0VHM43NSSWG info:eu-repo/semantics/closedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 2394765 bytes debruyn_2025.pdf https://biblio.ugent.be/publication/01JQRG2BWC5BBKN9AJXKAKMY3E/file/01KPX5JTK2HGZ9NZ4KJ1M1WTKP info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1358377 bytes publisher_version.pdf Debruyn, Gerben, Seung Choi, Jessica Leigh Dobson, Yana Maudens, Karen De Clerck, Matthew Shawkey, Shukang Zhang, and Liliana D’Alba Altamirano. 2025. “Convergence in Biomineralization Patterns across Animal Eggshells.” FARADAY DISCUSSIONS 261: 212–230. doi:10.1039/d5fd00028a.

However, their mechanical behavior under varying environmental conditions remains poorly understood. This work provides an in-depth analysis of the tensile properties of photo-cross-linked cinnamoyl-modified high-molar-mass PEtOx (PEtOx-Cin) nanofiber membranes with varying ambient humidity, assessing their practical handling prior to application as wound dressings, while exploring their shape memory properties as basis for potential humidity-actuated wound closure. Cinnamoyl modification and cross-linking of PEtOx-Cin mats significantly improve moisture stability, accelerate moisture sorption, and raise the glass transition temperature (Tg) through newly formed covalent intermolecular bonds. At higher relative humidity (%RH) from 25 to 65%RH, moisture sorption induces plasticization, shifting the Tg below room temperature and transforming the membranes from brittle to highly ductile and elastomeric. This glass-to-rubber transition under ambient conditions enables humidity-stimulated shape memory behavior, revealing excellent temporary shape fixity at low humidity and rapid recovery to the original shape upon exposure to high humidity. The presented findings advance the understanding of cross-linked PEtOx-Cin nanofiber membranes, and while further optimization is needed to enhance mechanical stability at high humidity for improved handling, they underscore their unique potential for next-generation wound closure dressings. journalArticle original public Article A1 published published ugent Olmo Frateur Olmo Frateur aut author 000150886227 802003501433 976840489813 0000-0002-0198-561X TW11 Martin Purino Martin Purino aut author 802001701879 978926536750 WE07 Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Richard Hoogenboom Richard Hoogenboom aut author 802000620432 975196852903 0000-0001-7398-2058 WE07 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Organic and Macromolecular Chemistry WE07 sht department 3S002821 4ad519a6-2a81-11ec-a6b4-cd4eac00b947 2021-11-01 2025-10-31 1944-8244 1944-8252 2025 17 16 24474 24484 2025 Technology and Engineering cinnamoyl poly(2-ethyl-2-oxazoline) photo-cross-linking electrospun nanofiber membranes humidity-dependent tensile properties humidity-actuated shape memory info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01JRCV45PEF3T562A4JY36C75P/file/01JRCVBZET62XCP67SFNVQYRG1 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 4452019 bytes frateur-et-al-2025-ambient-humidity-dependent-tensile-behavior-and-shape-memory-properties-of-cinnamoyl-photo-cross.pdf https://biblio.ugent.be/publication/01JRCV45PEF3T562A4JY36C75P/file/01JRCXRXC3SE2262GXDXKANH7Z info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 959734 bytes AAM PEtOx-Cin mech props.pdf Frateur, Olmo, Martin Purino, Lode Daelemans, Richard Hoogenboom, and Karen De Clerck. 2025. “Ambient Humidity-Dependent Tensile Behavior and Shape Memory Properties of Cinnamoyl Photo-Cross-Linked Poly(2-Ethyl-2-Oxazoline) Nanofibers.” ACS APPLIED MATERIALS & INTERFACES 17 (16): 24474–24484. doi:10.1021/acsami.5c03496.

Despite this potential, understanding and gearing the molecular parameters governing well-defined sol-gel electrospinnability remains a challenge, often requiring trial-and-error optimization. In this study, we (i) predicted the electrospinnability of methyltriethoxysilane (MTES)-based sol-gel systems by linking the viscosity evolution to key structural network parameters such as the hydrolysis degree and crosslinking functional groups distributions, and (ii) performed a comparative study to the leading building block tetraethoxysilane (TEOS), which is characterized by more crosslinking potential (4 arm TEOS vs 3 arm MTES). Using experimental data and coupled matrix-based Monte Carlo (CMMC) modeling, we determined Arrhenius parameters for MTES hydrolysis and condensation reactions. By applying the Arrhenius parameters to the non-isothermal synthesis conditions for electrospinning, accounting for evaporation, we retrieved molecular rules defining processing conditions, leading to no deposition, electrospraying and electrospinning. Using scanning electron microscopy (SEM) imaging, we confirmed the reliability of these molecular rules by randomly selecting three cases according to the kinetic model providing validation in predicting electrospinnability. Our predictive framework thus identifies molecular requirements for stable electrospinning, reducing reliance on empirical approaches, and facilitating the design of high-performance (organo)silica nanofiber membranes and sustainable applications. journalArticle original public Article A1 published published ugent Sofie Verschraegen Sofie Verschraegen aut author 000150868746 802003501534 919029486586 975200255882 0000-0002-6164-3662 TW11 Alice Novello Alice Novello aut author 000231441188 802004828111 975199409659 0009-0002-0113-7028 TW11 Eva Loccufier Eva Loccufier aut author 802002671374 974161061035 0000-0001-7045-2721 TW11 Alessandro Trigilio Alessandro Trigilio aut author 802003054526 977697655874 0000-0001-8878-9947 TW11 Klaartje De Buysser Klaartje De Buysser aut author 801001571962 978828372447 0000-0001-7462-2484 WE06 Dagmar D'hooge Dagmar D'hooge aut author 802000024082 973689492909 0000-0001-9663-9893 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Chemistry WE06 sht department 3F006621 190fbf11-2a82-11ec-95aa-05ef7abe0c3c 2021-11-01 2025-10-31 12B0D24N 30d3f7fd-19a5-11ee-b953-3bd20bad1f45 2023-10-01 2026-09-30 BOF/COR/2023/006 e031344b-4bcb-4dd8-ae59-d1d6a13e956a 2023-10-01 2026-09-30 01XP2017 5d4cf9bf-1c93-4aa6-8a09-3f1eb3287116 2017-02-01 2022-11-30 BOF/BAS/2022/105 3c6a72a5-6b2e-11ed-be68-4bd4c57b6d57 2022-12-15 2024-12-14 319309020 fa53f142-ef49-4d7e-ad16-584114152e03 2020-05-01 2024-04-30 1385-8947 1873-3212 2025 518 164509 2025 Technology and Engineering Structure-property relationships Crosslinking Model-based design Polymerization kinetics SI-29 NMR SOL NANOFIBERS POLYMERIZATION METHYLTRIETHOXYSILANE TETRAETHOXYSILANE FABRICATION HYDROLYSIS RHEOLOGY info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01JXHMJZD4TXWNG54VJE2GV2AT/file/01JXHNF2Q12H092RBJXA7FREYK info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 5814305 bytes 1-s2.0-S1385894725053458-main.pdf https://biblio.ugent.be/publication/01JXHMJZD4TXWNG54VJE2GV2AT/file/01JXHR9Z5QYV7GA4RDAKRAVCHH info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/vnd.openxmlformats-officedocument.wordprocessingml.document fullText http://purl.org/dc/dcmitype/Text 2822906 bytes main.docx https://biblio.ugent.be/publication/01JXHMJZD4TXWNG54VJE2GV2AT/file/01JXHRADRHBBVE86KSR3WNK7PK info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/vnd.openxmlformats-officedocument.wordprocessingml.document dataset http://purl.org/dc/dcmitype/Dataset 570043 bytes SI.docx Verschraegen, Sofie, Alice Novello, Eva Loccufier, Alessandro Trigilio, Klaartje De Buysser, Dagmar D’hooge, and Karen De Clerck. 2025. “Model-Based Molecular Rules for Electrospinning Solutions to Deliver Well-Defined Organosilica Membranes.” CHEMICAL ENGINEERING JOURNAL 518. doi:10.1016/j.cej.2025.164509.

An optimal synthesis recipe has been determined based on an Al‐alkoxide precursor (aluminum di(sec‐butoxide) acetoacetic ester chelate [ASB]). By using an initial molar composition of 1:3:0.2:0.8 for ASB:ethanol:hydrochloric acid:distilled water, and maintaining a dynamic viscosity between 50 and 150 mPa s, homogeneous alumina nanofibers with excellent thermal resistance are produced. The acidity, as an indicator of catalytic potential, was evaluated using NH3 temperature‐programmed desorption and compared with alternative catalysts of similar chemical nature, including cast alumina, γ‐alumina, and HZSM‐5. Testing of the alumina fibers as a catalyst in an esterification reaction (conversion of n‐pentanol and acetic acid into pentyl acetate) showed catalytic activity with higher conversion than the commercial alternatives. In addition, the reusability of the material was confirmed, thereby highlighting its potential as a highly efficient catalyst. journalArticle original public Article A1 published published ugent Minglun Li Minglun Li aut author 000161084967 802002448779 975880575688 TW11 Eva Loccufier Eva Loccufier aut author 802002671374 974161061035 0000-0001-7045-2721 TW11 Jozefien Geltmeyer Jozefien Geltmeyer aut author 000070582957 975000449525 0000-0002-1281-2968 Tom Vandevyvere Tom Vandevyvere aut author 979635896437 Varun Singh Varun Singh aut author 973111540334 Maarten Sabbe Maarten Sabbe aut author 801001769093 919019362618 971262821071 0000-0003-4824-2407 TW11 Jeroen Lauwaert Jeroen Lauwaert aut author 802001036017 977821688562 0000-0003-2781-3477 TW11 Hilde Poelman Hilde Poelman aut author 801000771108 973242707370 0000-0003-4267-7397 TW11 Vladimir Galvita Vladimir Galvita aut author 802000598103 973377731370 0000-0001-9205-7917 TW11 Dagmar D'hooge Dagmar D'hooge aut author 802000024082 973689492909 0000-0001-9663-9893 TW11 Klaartje De Buysser Klaartje De Buysser aut author 801001571962 978828372447 0000-0001-7462-2484 WE06 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department 3S009618 d937d58c-be65-11e9-ace9-8bf558aeac68 2018-01-01 2022-09-09 01B03518 320e7057-5b7c-11e9-ac93-1bffacd2a7e2 2018-06-01 2020-05-31 01J10219 1e0c3a2d-9d90-11e9-83f9-d13d95d2d7be 2019-10-01 2024-07-30 3S042419 57c1b13d-f98c-11e9-9191-7fc8fa7ad5b7 2019-11-01 2023-10-31 0002-7820 1551-2916 2025 108 10 e70007 2025 Technology and Engineering ceramics design of experiments electrospinning heterogeneous catalysis high purity alumina macropores sol-gel synthesis GAMMA-ALUMINA ACETIC-ACID ADSORPTION FIBERS TPD HYDROLYSIS MORPHOLOGY STABILITY MEMBRANES ZEOLITES info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01JWZKP23T4TKVTH0WP315NTG1/file/01JWZP4Z6RH4BKR5SQ3NHJ5YXH info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1408542 bytes Accepted manuscript paper 2 Minglun Li.pdf https://biblio.ugent.be/publication/01JWZKP23T4TKVTH0WP315NTG1/file/01K4AJNJ3W4CBZMCWDN5Q0XX37 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 3210403 bytes publisher_version.pdf Li, Minglun, Eva Loccufier, Jozefien Geltmeyer, Tom Vandevyvere, Varun Singh, Maarten Sabbe, Jeroen Lauwaert, Hilde Poelman, Vladimir Galvita, Dagmar D’hooge, Klaartje De Buysser, and Karen De Clerck. 2025. “One‐step Electrospinning of Alumina Nanofibers to Create a Competitive Esterification Catalyst.” JOURNAL OF THE AMERICAN CERAMIC SOCIETY 108 (10). doi:10.1111/jace.70007.

The tests were performed for different fibre angles (0°, 45°, 90°), moisture contents (dry, 50%RH), and strain rates (10^(-4), 10^(-2), 10^(-1) s^(-1)). Digital image correlation (DIC) was coupled with infrared thermography. The contribution of the local strains, strain rates and temperatures to the global mechanical behaviour was investigated throughout deformation. The initial thermoelastic response was used to estimate the coefficient of thermal expansion. In PA6, neck development caused significant self-heating at high strain rates, differently between dry and 50%RH. In glass/PA6, however, temperature rises were always small (< +3 °C) despite local strain rate peaks in the fracture zone. This was ascribed to limited plastic deformation, as confirmed by post-mortem microscopy. The full-field data can be highly valuable for the development of advanced constitutive models for both pure polymer and short fibre composite. journalArticle original public Article A1 published published ugent 1 Daniele Finazzi Daniele Finazzi aut author 971313003619 0000-0002-6418-6823 UGent Yuriy Sinchuk Yuriy Sinchuk aut author 000181163563 802002870226 972445366562 0000-0002-2007-9874 UGent Ruben Sevenois Ruben Sevenois aut author 979446364396 0000-0003-4977-2522 UGent Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Gilles Robert Gilles Robert aut author Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department 179L03420 4060755c-bdc2-49a5-8d00-487761e9afd8 2020-06-01 2024-05-31 01XP1717 c007e1ff-1de1-43a1-8ef5-573ce37d58c1 2017-02-01 2024-01-31 3E005020 19af023b-d7df-11ea-aa27-b1f81ec15cf7 2020-10-01 2023-04-16 0142-9418 1873-2348 2024 132 108361 2024 Technology and Engineering Chemistry Physics and Astronomy Polyamide-6 (PA6) Short fibre-reinforced composites (SFRPs) Tensile tests Digital image correlation (DIC) Self-heating info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01HPKKW4536F09QX221966778V/file/01HPKM10ZZ3DKR18GYWKGD8R0Q info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 15242275 bytes Finazzi et al (2024).pdf Finazzi, Daniele, Yuriy Sinchuk, Ruben Sevenois, Lode Daelemans, Karen De Clerck, Gilles Robert, and Wim Van Paepegem. 2024. “Study of Self-Heating and Local Strain Rate in Polyamide-6 and Short Fibre Glass/Polyamide-6 under Tension through Synchronised Full-Field Strain and Temperature Measurements.” POLYMER TESTING 132. doi:10.1016/j.polymertesting.2024.108361.

Safe design requires understanding of their complex mechanical behaviour under the influence of temperature, moisture, and strain rate. Two models often applied in the literature are the temperature-humidity equivalence and the time-temperature superposition (TTS), however their accuracy to describe the full mechanical response is still unclear. By generating high-quality data, this paper conducts a quantitative study of these models on the mechanical response of injection-moulded PA6 and GPA6 with a very high fibre content (50 wt%). The materials were conditioned either dry or at 50%RH. Dynamic mechanical analysis (DMA) was used to measure the glass transition temperature of dry PA6 and 50%RH PA6, and to construct TTS master curves. Tensile tests were then conducted at different combinations of temperature, moisture, and strain rate. Comparison of the tensile true stress-true strain curves revealed that the proposed models fail to capture the effects of the thermal history, which may cause microstructural modifications as demonstrated with differential scanning calorimetry (DSC). The link between DSC, DMA, and tensile data constitutes a novelty of this work and was possible because all the samples had the same hygro-thermal history. Additionally, self-heating of PA6 causes deviations from the TTS at large strains. The results of this study may help develop more accurate material models, ultimately improving the design of structural automotive parts. journalArticle original public Article A1 published published ugent 1 Daniele Finazzi Daniele Finazzi aut author 971313003619 0000-0002-6418-6823 UGent Guillem Seychal Guillem Seychal aut author Jean-Marie Raquez Jean-Marie Raquez aut author Gilles Robert Gilles Robert aut author Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department 179L03420 4060755c-bdc2-49a5-8d00-487761e9afd8 2020-06-01 2024-05-31 179A00124 459bbf55-10bd-41a9-a79e-67bbede9ed3f 2024-07-01 2027-06-30 0142-9418 1873-2348 2024 141 108653 2024 Chemistry Technology and Engineering Polyamide-6 (PA6) Short fibre-reinforced polymers (SFRPs) Time-temperature superposition (TTS) Dynamic mechanical analysis (DMA) Differential scanning calorimetry (DSC) Tensile tests PLASTIC-DEFORMATION WATER TRANSITION POLYMERS RELAXATION BEHAVIOR info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01JDW0BCRZK37JEJ1VBA4BTBPW/file/01JDW0E0VSRCB70QHK3CE1N1QH info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 2842831 bytes Finazzi et al (2024)-3.pdf Finazzi, Daniele, Guillem Seychal, Jean-Marie Raquez, Gilles Robert, Karen De Clerck, Lode Daelemans, and Wim Van Paepegem. 2024. “Study of the Temperature-Humidity Equivalence and the Time-Temperature Superposition Principle in the Finite-Strain Response of Polyamide-6 and Short Glass Fibre-Reinforced Polyamide-6.” POLYMER TESTING 141. doi:10.1016/j.polymertesting.2024.108653.

However, further expansion and exploitation of these materials require broadening the portfolio of Si-based precursors. In the present work, a part of the Si–O–Si linkages is therefore replaced by terminal groups (Si–R) or bridged organic linkages (Si-R-Si), playing with the inorganic-organic precursor balance considering triethoxymethylsilane (TEOMS), bis(triethoxysilyl)methane (BTESM) or bis(triethoxysilyl)ethane (BTESE). Both a rheological and kinetic analysis for the sol-gel synthesis of these three precursors is first done in comparison with the TEOS-based reference system, followed by an in-depth study of the electrospinning potential and the resulting organosilica nanofibrous materials properties. The production of the nanofibrous materials is achieved by electrospinning of a partly cross-linked sol-gel system with an optimal initial precursor/H2O/EtOH ratio selecting a sufficiently low temperature. It is demonstrated that the precursor/H2O ratio mainly controls the reactivity of the polycondensation by hydrolysis enhancement, and the precursor/EtOH ratio allows control over the dynamic viscosity due to dilution of the system. Depending on the chemical structure, a different range of workable viscosity conditions is obtained, highlighting the relevance of the construction of structure-property relationships. The rheological and kinetic analysis underpinned the relation of chemistry building blocks and organosilica network synthesis for material applications in general for the first time. Overall, a wide portfolio of membrane properties is reported, including the control over water take-up, acidity and basicity strength, and thermal stability starting from molecular thus chemical variations. journalArticle original public Article A1 published published ugent 5 Eva Loccufier Eva Loccufier aut author 802002671374 974161061035 0000-0001-7045-2721 TW11 Sofie Verschraegen Sofie Verschraegen aut author 000150868746 802003501534 919029486586 975200255882 0000-0002-6164-3662 TW11 Bianca Swanckaert Bianca Swanckaert aut author 978889457589 0000-0001-6036-6512 Dagmar D'hooge Dagmar D'hooge aut author 802000024082 973689492909 0000-0001-9663-9893 TW11 Klaartje De Buysser Klaartje De Buysser aut author 801001571962 978828372447 0000-0001-7462-2484 WE06 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Chemistry WE06 sht department 3F006621 190fbf11-2a82-11ec-95aa-05ef7abe0c3c 2021-11-01 2025-10-31 3S039119 9cfd7b5f-f96d-11e9-b85e-e128f57a36f9 2019-11-01 2023-10-31 01B03518 320e7057-5b7c-11e9-ac93-1bffacd2a7e2 2018-06-01 2020-05-31 01J10219 1e0c3a2d-9d90-11e9-83f9-d13d95d2d7be 2019-10-01 2024-07-30 3S009618 d937d58c-be65-11e9-ace9-8bf558aeac68 2018-01-01 2022-09-09 2468-5194 2024 36 101950 2024 Technology and Engineering Organosilica nanofibers Sol-gel synthesis Electrospinning Chemical inertness Wettability control info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01HNZ8NZC5ENVF6C63C1FJNPJC/file/01HNZ9NDNEHS44EEH6Z5C7EC9R info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 15756278 bytes 1-s2.0-S2468519424000569-main.pdf https://biblio.ugent.be/publication/01HNZ8NZC5ENVF6C63C1FJNPJC/file/01HNZDAYQ9XFCPGNCKE6J99M61 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/vnd.openxmlformats-officedocument.wordprocessingml.document fullText http://purl.org/dc/dcmitype/Text 5973902 bytes Manuscript Materials Today Chemistry.docx Loccufier, Eva, Sofie Verschraegen, Bianca Swanckaert, Dagmar D’hooge, Klaartje De Buysser, and Karen De Clerck. 2024. “A Broad Spectrum of Electrospun Organosilica Membrane Properties by Tuning the Chemical Nature of the Precursor Building Block.” MATERIALS TODAY CHEMISTRY 36. doi:10.1016/j.mtchem.2024.101950.

However, its water-solubility limits its application in situations where a stable, nanofibrous morphology is required in aqueous environments. The present work offers a straightforward route towards water-stable PEtOx-based nanofibrous membranes, via post-polymerization functionalization with cinnamoyl moieties (PEtOx-Cin) and photo-crosslinking of the electrospun membranes. It is shown that a UVB treatment does not significantly affect the nanofibrous morphology, while successfully inducing the cinnamoyl dimerization process and hence the formation of a polymeric network, as evidenced by spectral analysis. The hereby crosslinked PEtOx-based nanofibers exhibit a prolonged water-stability (at least 45 days), while, interestingly, intermediate irradiation times yield the best results. Full disintegration of the photo-crosslinked nanofibers in aqueous media could be achieved by subsequent UVC exposure. This is not only due to decrosslinking of the cinnamoyl dimers, but was also found to be due to partial degradation of the polymeric backbone. The investigation of UVB/UVC exposure on pure PEtOx nanofibrous membranes confirmed the photo-degradation of the polymeric backbone by a significant decrease in molar mass as observed by size exclusion chromatography and supported by spectral analysis. The hereby proposed, straightforward route for reversible crosslinking of PEtOx-based nanofibrous membranes and their accessible disintegration will contribute to the promotion of these materials in biomedical applications where a water-stable, nanofibrous morphology combined with high hydrophilicity and easy removal is required. journalArticle original public Article A1 published published ugent 2 Olmo Frateur Olmo Frateur aut author 000150886227 802003501433 976840489813 0000-0002-0198-561X TW11 Jana Becelaere Jana Becelaere aut author 977861082888 0000-0001-5024-3308 Ronald Merckx Ronald Merckx aut author 974260040744 0000-0002-2867-0888 Joachim Van Guyse Joachim Van Guyse aut author 000080062786 802001924676 979806612797 Martin Purino Martin Purino aut author 802001701879 978926536750 WE07 Richard Hoogenboom Richard Hoogenboom aut author 802000620432 975196852903 0000-0001-7398-2058 WE07 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Organic and Macromolecular Chemistry WE07 sht department 3S002821 4ad519a6-2a81-11ec-a6b4-cd4eac00b947 2021-11-01 2025-10-31 3S000718 d89c7f90-be65-11e9-ace9-8bf558aeac68 2018-01-01 2022-12-31 01B03518 320e7057-5b7c-11e9-ac93-1bffacd2a7e2 2018-06-01 2020-05-31 0014-3057 2024 212 113076 2024 Technology and Engineering Chemistry Solvent electrospinning Nanofibers Poly(2-ethyl-2-oxazoline) Cinnamoyl Photo-crosslinking Water-stability Photo-degradation CRYSTAL ALIGNMENT PROPERTIES ELECTROSPUN NANOFIBERS PARTIAL HYDROLYSIS DRUG-DELIVERY POLY(2-OXAZOLINE)S LINKING POLY(2-ETHYL-2-OXAZOLINE) PHOTOREACTIVITY POLYMERIZATION NANOPARTICLES info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01HX9H1DPNFY4XKVNWCZ8ZRB09/file/01HX9HCHZQGF90BVSGGJ1ESHM7 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 9271297 bytes 1-s2.0-S0014305724003379-main.pdf https://biblio.ugent.be/publication/01HX9H1DPNFY4XKVNWCZ8ZRB09/file/01HX9HD9BP9QENH5ZSV15J72DC info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 3020199 bytes Manuscript PEtOx-Cin photocrosslinking_final_accepted.pdf https://biblio.ugent.be/publication/01HX9H1DPNFY4XKVNWCZ8ZRB09/file/01HX9HEC9BH3JDYGWJ5KDJQCHV info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf dataset http://purl.org/dc/dcmitype/Dataset 1462959 bytes Supplementary data_final.pdf Frateur, Olmo, Jana Becelaere, Ronald Merckx, Joachim Van Guyse, Martin Purino, Richard Hoogenboom, and Karen De Clerck. 2024. “Development of Reversibly Photo-Crosslinkable Water-Stable Poly(2-Ethyl-2-Oxazoline) Nanofibers via Functionalization with Cinnamoyl Moieties.” EUROPEAN POLYMER JOURNAL 212. doi:10.1016/j.eurpolymj.2024.113076.

The tests were performed for different dominant angles of the short fibres (0°, 45°, 90°), moisture contents (dry, 50%RH), and strain rates (10 −4 , 10 −2 , 10 −1 s −1). Digital image correlation (DIC) was coupled with infrared thermography. The contribution of the local strains, strain rates and temperatures to the global mechanical behaviour was investigated throughout deformation. The initial thermoelastic response was used to estimate the coefficient of thermal expansion. In PA6, neck development caused significant self-heating at high strain rates, differently between dry and 50%RH. In glass/PA6, however, temperature rises were always small (< +3 °C) despite local strain rate peaks in the fracture zone. This was ascribed to limited plastic deformation, as confirmed by post-mortem microscopy. The full-field data can be highly valuable for the development of advanced constitutive models for both pure polymer and short fibre composite. conference proceedingsPaper public C1 published published ugent Daniele Finazzi Daniele Finazzi aut author 971313003619 0000-0002-6418-6823 UGent Gilles Robert Gilles Robert aut author Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Cristophe Binetruy Cristophe Binetruy edt editor Frédéric Jacquemin Frédéric Jacquemin edt editor Department of Materials, Textiles and Chemical Engineering TW11 sht department Nantes, France 2024-07-02 2024-07-05 179L03420 4060755c-bdc2-49a5-8d00-487761e9afd8 2020-06-01 2024-05-31 9782912985019 The European Society for Composite Materials (ESCM) and the Ecole Centrale de Nantes. 2024 3 122 129 2024 Technology and Engineering info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01J28RPZ13508VRDJ8H14JS2KS/file/01J28S6D6JAECEE5F00CYV4R27 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 916294 bytes 3_FINAZZI_Daniele_IW9H1.pdf https://eccm21.org/ open fullText http://purl.org/dc/dcmitype/InteractiveResource https://sdrive.cnrs.fr/s/Hsy686dM2S6fYGw?dir=undefined&openfile=4079071 open fullText http://purl.org/dc/dcmitype/InteractiveResource https://gem.ec-nantes.fr/en/eccm21-proceedings/ open fullText http://purl.org/dc/dcmitype/InteractiveResource Finazzi, Daniele, Gilles Robert, Lode Daelemans, Karen De Clerck, and Wim Van Paepegem. 2024. “Thermomechanical Coupling during Tensile Testing of PA6 and Short Fibre Glass/PA6.” In Proceedings of the 21st European Conference on Composite Materials : Volume 3 : Material and Structural Behavior Simulation & Testing, ed by.

A high specific surface area and a good active phase dispersion are generally essential to create catalytic materials with a large number of active sites. Notably, materials with a fibrous morphology are appealing because of their large surface‐to‐volume ratio and flexibility. This contribution highlights the morphology of different types of fibrous structures currently under investigation, all the way from the nanoscale to the macroscale and back, where the distinction lies in the length and diameter of the fibers, as well as in the connection between the structures. Fibers with at least one submicron to nanoscale characteristic result in a higher yield, but can display practical usability issues when unbound. Therefore, fibrous structure catalysts with a balance between the small diameter and handleability are important for industrial viability. By combining different morphologies, the best of both nanomaterials and macroscopic integer materials can be combined into advanced catalytic materials. This overview showcases the large potential of these materials but makes clear that further research is needed to keep expanding the use and effectiveness of fibrous structures in catalysis. journalArticle review public Review A1 published published ugent 9 Eva Loccufier Eva Loccufier aut author 802002671374 974161061035 0000-0001-7045-2721 TW11 Damien P.

Five different Si-alkoxy chlorides were tried as reagents at room temperature, allowing for an easy two-step production process. Trimethylchlorosilane (TMCS) was determined as to be the most suitable modifier, for this purpose. The modified membrane exhibits long-term hydrophobicity even under high humidity and water submersion, maintaining this property after exposure to elevated temperatures and acidic conditions, surpassing the unmodified membrane. The separation effectiveness for immiscible water/solvent solutions was proven, followed by an investigation into the relation between the surface tension of some miscible water/solvent solutions and the resulting wetting behavior of the TMCS-modified membrane, to utilize the membrane as a process intensification tool, specifically as a solvent gate. journalArticle original public Article A1 published published ugent 1 Minglun Li Minglun Li aut author 000161084967 802002448779 975880575688 TW11 Eva Loccufier Eva Loccufier aut author 802002671374 974161061035 0000-0001-7045-2721 TW11 Jozefien Geltmeyer Jozefien Geltmeyer aut author 000070582957 975000449525 0000-0002-1281-2968 Dagmar D'hooge Dagmar D'hooge aut author 802000024082 973689492909 0000-0001-9663-9893 TW11 Klaartje De Buysser Klaartje De Buysser aut author 801001571962 978828372447 0000-0001-7462-2484 WE06 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Chemistry WE06 sht department 01J10219 1e0c3a2d-9d90-11e9-83f9-d13d95d2d7be 2019-10-01 2024-07-30 3S009618 d937d58c-be65-11e9-ace9-8bf558aeac68 2018-01-01 2022-09-09 01B03518 320e7057-5b7c-11e9-ac93-1bffacd2a7e2 2018-06-01 2020-05-31 2524-7921 2524-793X 2024 6 1 145 157 2024 Technology and Engineering Chemistry Polymers and Plastics Materials Chemistry Electronic, Optical and Magnetic Materials Materials Science (miscellaneous) Electrospinning Nanofibers silica Post-functionalization Hydrophobicity Separation barrier WATER FABRICATION STABILITY REMOVAL FILTRATION COMPOSITE MATS MESH OIL info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01HEMVT5YQPNE0S9D0E80PSVBM/file/01HEMXMETAM80E1WX4Z7RJZW8F info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1040226 bytes Manuscript Advanced Fiber Materials.pdf https://biblio.ugent.be/publication/01HEMVT5YQPNE0S9D0E80PSVBM/file/01J091YA77JZTNPDQYZTQE4HSH info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 2381976 bytes s42765-023-00335-y.pdf Li, Minglun, Eva Loccufier, Jozefien Geltmeyer, Dagmar D’hooge, Klaartje De Buysser, and Karen De Clerck. 2024. “Playing with Chlorine-Based Post-Modification Strategies for Manufacturing Silica Nanofibrous Membranes Acting as Stable Hydrophobic Separation Barriers.” ADVANCED FIBER MATERIALS 6 (1): 145–157. doi:10.1007/s42765-023-00335-y.

The flexural strength and interlaminar shear strength of the composites remained unaffected by the addition of nanofibers: around 750 MPa and 63 MPa for CP, 550 MPa and 58 MPa for QI, and 650 MPa and 50 MPa for W, respectively. The incorporation of nanofibers in the interlaminar regions resulted in a substantial reduction in projected damage area, ranging from 30% to 50% reduction over an impact energy range of 5-20 J. Microscopic analysis showed that especially the delamination damage decreased in toughened composites, while intralaminar damage remained similar for the cross-ply and quasi-isotropic lay-ups and decreased only in the woven lay-up. This agrees with the broad body of research that shows that interleaved nanofibers result in a higher delamination resistance due to toughening mechanisms related to nanofiber bridging of cracks. Despite their ability to mitigate delamination during impact, nanofibers showed limited positive effects on Compression After Impact (CAI) strength in quasi-isotropic and cross-ply composites. Interestingly, only the woven fabric composites demonstrated improved CAI strength, with a 12% improvement on average over the impact energy range, attributed to a reduction in both interlaminar and intralaminar damage. This study indicates the critical role of fiber integrity over delamination size in determining CAI performance, suggesting that the delaminations are not sufficiently large to induce buckling of sub-layers, thereby minimizing the effect of nanofiber toughening on the CAI strength. journalArticle original public Article A1 published published ugent 4 Timo Meireman Timo Meireman aut author 972580996713 Erik Verboven Erik Verboven aut author 802002619642 977116732473 0000-0001-6164-0130 UGent Mathias Kersemans Mathias Kersemans aut author 802000786039 977395323042 0000-0002-9325-0556 TW11 Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department BOF/STA/202009/046 25182d45-ccf4-11eb-9f0b-e5cd0f711fbd 2021-07-01 2025-06-30 2073-4360 2024 16 21 3060 2024 Technology and Engineering damage resistance electrospinning residual compressive strength DELAMINATION FIBER/EPOXY BEHAVIOR INTERLEAVES info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01JS1WW95NEXW8TQ56G5193VPX/file/01JS1XFZB6GV8H2J9ZNV6AYNY7 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 6491297 bytes polymers-16-03060-v2.pdf Meireman, Timo, Erik Verboven, Mathias Kersemans, Wim Van Paepegem, Karen De Clerck, and Lode Daelemans. 2024. “Low-Velocity Impact Resistance and Compression after Impact Strength of Thermoplastic Nanofiber Toughened Carbon/Epoxy Composites with Different Layups.” POLYMERS 16 (21). doi:10.3390/polym16213060.

Notably, poly(2-ethyl-2-oxazoline) (PEtOx) presents remarkable potential due to its high hydrophilicity in situations where hygroscopic behaviour is desired, as illustrated by ongoing pre-clinical trials on PEtOx-drug conjugates (Moreadith et al. 2017), positioning PEtOx as a commercially competitive alternative to the more established poly(ethylene glycol) (PEG). By combining this material with the versatility and scalability of the solvent electrospinning technique, PAOx nanofibrous membranes emerge as an attractive support-material for demanding (biomedical) applications. However, the inherent water-solubility of PEtOx limits its application in situations where a stable, nanofibrous morphology is required in aqueous environments, such as in tissue engineering or wound dressings. The present work offers a straightforward route towards biocompatible, water-stable PEtOx-based nanofibrous membranes, via photo-crosslinking of the electrospun membranes comprising cinnamoyl-bearing PEtOx (PEtOx-Cin). The proposed functionalisation of PEtOx with cinnamoyl moieties entails a two-step process, involving partial hydrolysis of PEtOx to incorporate reactive polyethyleneimine units, followed by cinnamoyl addition. This post-polymerization approach allows for the utilization of large-scale, commercially available materials. After successful synthesis, homogeneous PEtOx-Cin nanofibrous mats are electrospun using only green solvents, in a process similar to that for unmodified PEtOx. It is revealed that a UVB treatment does not significantly affect the nanofibrous morphology, while successfully inducing the cinnamoyl dimerization process and hence the formation of a polymeric network, as evidenced by spectral analysis. Indeed, conversions of up to 95% after 24 h of UVB exposure of 10% functionalised PEtOx-Cin could be reached. The hereby crosslinked PEtOx-based nanofibers exhibit prolonged water-stability (at least 45 days), while, interestingly, intermediate irradiation times (5 h) yield the best results. Full disintegration of the photo-crosslinked nanofibers in aqueous media could be achieved by subsequent UVC exposure. This is not only due to decrosslinking of the cinnamoyl dimers, but also due to partial degradation of the polymeric backbone. Investigation of UVB/UVC exposure on pure PEtOx nanofibrous membranes confirmed the photo-degradation of the polymeric backbone, evidenced by a significant decrease in molar mass as observed by size exclusion chromatography and supported by spectral analysis. The hereby proposed, straightforward methodology for reversible biocompatible crosslinking of PEtOx-based nanofibrous membranes and their accessible disintegration will contribute to advance these materials in biomedical applications necessitating water-stable, nanofibrous morphologies combined with high hydrophilicity and easy removal.

These properties are ideally acquired from a model test similar to the real composite, while excluding the effects of fibre fractures and the induced debonding interactions. Therefore, in this study, debonding growth was examined in detail, using novel single short fibre specimens, which were fabricated using a new methodology. These experiments were further complemented with a continuous fibre case study, where the established single fibre fragmentation specimens were evaluated. The progression of debonding and pull-out damages versus remote stress was studied for two fibre sizings utilizing real-time in-situ polarized light microscopy. A finite element model was built to obtain the fibre/matrix interfacial fracture toughness considering thermal residual stresses, friction and matrix plasticity, and a very good correlation was obtained between the model and the experiments. journalArticle original public Article A1 published published ugent 1 Mehdi Nikforooz Mehdi Nikforooz aut author 976302603389 UGent Olivier Verschatse Olivier Verschatse aut author 974442908376 0000-0001-7732-6007 Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department 42K04518 e6e611b3-3d00-4b6b-af90-0e1a065a1d3d 2018-11-01 2023-10-31 BOF/STA/202009/046 25182d45-ccf4-11eb-9f0b-e5cd0f711fbd 2021-07-01 2025-06-30 01J10219 1e0c3a2d-9d90-11e9-83f9-d13d95d2d7be 2019-10-01 2024-07-30 01B03518 320e7057-5b7c-11e9-ac93-1bffacd2a7e2 2018-06-01 2020-05-31 BOF/24J/2023/006 958ee467-1003-11ee-a391-81a6d079669c 2023-10-01 2027-09-30 160A08923 548bb758-1ab6-4d6d-893a-6f0a6cbbb94a 2023-11-01 2026-10-31 0142-9418 1873-2348 2024 134 108435 2024 Technology and Engineering Polymer-matrix composites Interface Debonding Mechanical testing Polarized light microscopy Finite element analysis info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01HX75FB27ARZCM04678FF34G9/file/01J039QF1NK9JY54KGGKAQ78AE info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 16051162 bytes Publisher_version.pdf Nikforooz, Mehdi, Olivier Verschatse, Lode Daelemans, Karen De Clerck, and Wim Van Paepegem. 2024. “Mixed Experimental-Numerical Method for Quantitative Measurement of Mode II Fibre/Matrix Interface Debonding and Comparison of Fibre Sizings in Single Short Fibre Composites.” POLYMER TESTING 134. doi:10.1016/j.polymertesting.2024.108435.

This synergy might differ for strong and weak fibre/ matrix bondings inducing discrete debonding patterns. This study employed an optical visualization technique to investigate, for the first time, the mixed-mode debonding growth for short fibres with different sizings and offaxis angles, through in-situ real-time measurements. For this purpose, embedded single short-fibre specimens were fabricated using E-glass fibres and an epoxy matrix, with a novel and more efficient manufacturing method than done so far in literature. E-glass fibres with two different sizings were utilized, including a polypropylenecompatible (weak) sizing and an epoxy-compatible (strong) sizing. While there was a relatively rapid debonding growth for the transverse fibres with the weak sizing, the strong sizing experienced a gradual debonding growth independent of the fibre angle. For the weak sizing, partial debonding cracks were initiated at different locations along the length of the fibres, where they coalesced into dominant debonding cracks. For the strong sizing, debonding was always initiated and localized at the fibre tip, and there was a clear synchronous propagation of debonding in the arc and length of the fibre. journalArticle original public Article A1 published published ugent 3 Mehdi Nikforooz Mehdi Nikforooz aut author 976302603389 UGent Olivier Verschatse Olivier Verschatse aut author 974442908376 0000-0001-7732-6007 Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department 160A08923 548bb758-1ab6-4d6d-893a-6f0a6cbbb94a 2023-11-01 2026-10-31 0266-3538 1879-1050 2024 249 110488 2024 Technology and Engineering Short-fibre composites Debonding Fibre/matrix bond Interface Optical microscopy FRAGMENTATION TEST DAMAGE MECHANISMS NORMAL STRENGTH MATRIX INTERFACE FAILURE ADHESION BEHAVIOR info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01HX74Q9CWJD0E3V5H4GST2CT7/file/01JD7P0Z7ENRH5Z6E99PKPA81C info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 17346711 bytes publisher version.pdf https://biblio.ugent.be/publication/01HX74Q9CWJD0E3V5H4GST2CT7/file/01K6A77EZMT48WB7F5JYR17EBC info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 2263940 bytes Nikforooza M et al Accepted Manuscript.pdf Nikforooz, Mehdi, Olivier Verschatse, Lode Daelemans, Karen De Clerck, and Wim Van Paepegem. 2024. “Experimental Method for In-Situ Real-Time Measurement of Mixed Mode Fibre/Matrix Interface Debonding and Comparison of Fibre Sizings in Single Short Fibre Composites.” COMPOSITES SCIENCE AND TECHNOLOGY 249. doi:10.1016/j.compscitech.2024.110488.

Compared to conventional fibrous structures, nanofibers are lightweight materials with small diameters, high porosity, controllable pore structures, and a high surface-to-volume ratio. To this end, cross-linking ensures solvent stability, making them ideal for various applications in which solvent contact or humid environments are prerequisites. This review aims to highlight the potential of nanofiber networks beyond their solvent resistivity by emphasizing the chemical reactivity of such novel systems and constructs. To this end, an overview of approaches for the preparation of a reactive nanofibrous network is presented, including the most recent (versatile) functional nanofiber reactive networks. journalArticle review public Article A1 published published ugent 5 Ronald Merckx Ronald Merckx aut author 974260040744 0000-0002-2867-0888 Vinita Dhaware Vinita Dhaware aut author 802004333411 973085367613 WE07 Meike Leiske Meike Leiske aut author 802003771720 975263848375 UGent Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Richard Hoogenboom Richard Hoogenboom aut author 802000620432 975196852903 0000-0001-7398-2058 WE07 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Organic and Macromolecular Chemistry WE07 sht department 3S012019 4b38d931-60d8-11e9-aa53-555acf89d448 2019-01-01 2022-12-31 0897-4756 1520-5002 2024 36 19 9189 9206 2024 Chemistry PHOTO-CROSS-LINKING ELECTROSPUN GELATIN NANOFIBERS PH-RESPONSIVE NANOFIBERS CLICK CHEMISTRY BIOMOLECULAR IMMOBILIZATION BIOMEDICAL APPLICATIONS RADICAL POLYMERIZATION BLOCK-COPOLYMERS FABRICATION FIBERS info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01JAFVP59BHK4BMNWMSZBHSRQ9/file/01JAFVTNX86CY77VSJ7PWNW10E info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 12891093 bytes merckx-et-al-2024-reactive-nanofiber-networks-from-a-chemistry-perspective.pdf https://biblio.ugent.be/publication/01JAFVP59BHK4BMNWMSZBHSRQ9/file/01JSKFZHKNTB1PAH2MF1CKKMXM info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1476933 bytes Reactive_fibers-Review_ChemistryOfMaterials_AAM.pdf Merckx, Ronald, Vinita Dhaware, Meike Leiske, Karen De Clerck, and Richard Hoogenboom. 2024. “Reactive Nanofiber Networks from a Chemistry Perspective.” CHEMISTRY OF MATERIALS 36 (19): 9189–9206. doi:10.1021/acs.chemmater.4c00277.

The design of such large-scale chemical entities is challenging, primarily hindered by the limited comprehension of the effect of reaction conditions on the final macroscopic properties of polymer gels and their product performance due to a lack of proper characterization tools for such complex topologies. Our research group has developed a combined kinetic Monte Carlo and molecular dynamics tool that accounts for kinetics, thermodynamics, and topological features of the formed polymeric networks. By employing this in silico-based characterization tool, we can thoroughly examine the structural evolution of individual macromolecules/segments throughout network formation. This facilitates the fundamental insight into structure-property relationships, bridging the molecular and material scales, and enables the development of synthesis protocols toward maximal material performance. In this work, experimental studies into the synthesis, material characterization, and practical application level of organosilica networks demonstrate the high validation potential of this advanced tool. One notable application is the sol-gel-based synthesis of organosilica networks for electrospinning highly resistant filtration membranes.

Life on Earth imposes a series of environmental challenges on eggs, often presenting conflicting or contradicting demands. For example, eggs must be crack-resistant yet allow breakage from the inside, be impermeable to bacteria yet breathable and in some cases allow water absorption. Eggshells also offer protection from harmful radiation while allowing some light transmission. As a result, they have evolved into multifunctional systems with extraordinary properties, including unique combinations of high flexibility and strength, strong water absorption and antimicrobial filtration. Biomimicking of these natural structures could lead to the development of new materials with advanced properties for filtration/separation technology, sensors and biomedical applications. Through chemical and physical analysis of sixty-two reptile eggshells (Debruyn et al., 2024), the key structural components - namely a proteinaceous layer (primarily keratin) and an inorganic calcium carbonate component - were identified and used to develop biomimicry models. The non-woven layer of proteinaceous fibers closely resembles randomly oriented nanofibrous membranes produced via solvent electrospinning. Hence, keratin, extracted through a sulphitolysis process, was electrospun from formic acid. A subsequent heat treatment ensured crosslinking of residual amine and carboxyl groups in the keratin chains, imparting hydrophobicity and improved water stability to the nanofibrous membranes. To further approximate the eggshell’s inner proteinaceous layer, the keratin nanofibers were embedded in an egg white matrix using a dip-coating procedure. The mineral component, typically found in Testudines and Crocodylia eggshells, was mimicked by depositing calcium carbonate particles onto the keratin-based membranes. This biomimetic approach paves the way for the production of multifunctional, biocompatible keratin-based membranes tailored to the specific needs of various end-applications such as filtration membranes, wound dressings, smart textiles, etc. conference poster public C3 published published ugent Yana Maudens Yana Maudens aut author 000180496485 802004439404 973207706538 0009-0004-7574-7309 TW11 Gerben Debruyn Gerben Debruyn aut author 802003560037 976557705309 WE11 Eva Loccufier Eva Loccufier aut author 802002671374 974161061035 0000-0001-7045-2721 TW11 Cinzia Tonetti Cinzia Tonetti aut author Claudia Vineis Claudia Vineis aut author Alessio Varesano Alessio Varesano aut author Liliana D'Alba Altamirano Liliana D'Alba Altamirano aut author 802002269634 0000-0002-2478-3455 WE11 Matthew Shawkey Matthew Shawkey aut author 802002093216 979048085026 0000-0002-5131-8209 WE11 Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Biology WE11 sht department Ghent, Belgium 2024-11-27 2024-11-27 3G0A7921 ae3ff06f-4420-11eb-809b-01df1efbbcb6 2021-01-01 2024-12-31 2024 2024 Biology and Life Sciences Technology and Engineering info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01JHQNV8627WFA9YP4942R9H7P/file/01JHQPJPE1Z15QBZFXE80ZZV33 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1996463 bytes 241115 FEARS 2024.pdf Maudens, Yana, Gerben Debruyn, Eva Loccufier, Cinzia Tonetti, Claudia Vineis, Alessio Varesano, Liliana D’Alba Altamirano, Matthew Shawkey, Lode Daelemans, and Karen De Clerck. 2024. “Biomimicry of Reptile Eggshells Based on Electrospun Keratin Membranes.” In 2024 FEA Research Symposium, Abstracts. doi:10.5281/zenodo.15076977.

Because non-avian reptiles are rarely incubated, they must be heated by, and absorb water from, the oviposition site for the developing embryo. The mechanisms by which they absorb sufficient, but not excess, water and how these mechanisms vary with local habitat is largely unknown, despite its significance to their evolution. Here, we first performed histology, Fourier-transform infrared spectroscopy and dynamic vapor sorption experiments to elucidate the mechanisms of eggshell absorption for 56 reptile species. Then, we used phylogenetic comparative analysis to test the hypothesis that the absorptive capacity of reptile eggshells increases with aridity of the environment. We found that water absorption increases in the presence of a superficial mucopolysaccharide layer and decreases with increased calcium content. We found that eggs from arid environments have highly absorbent eggshells, but only in species with weakly calcified shells. Our results suggest that reptile eggshells have over evolutionary time tuned absorptive capacity to environmental moisture level. Since these eggs often must sustain conflicting constraints, they may serve as inspirations for new biomimetic materials, such as water filtering membranes or humidity sensors. journalArticle original public Article A1 published published ugent 3 Gerben Debruyn Gerben Debruyn aut author 802003560037 WE11 Jozefien Geltmeyer Jozefien Geltmeyer aut author 000070582957 975000449525 0000-0002-1281-2968 Ella Schoolaert Ella Schoolaert aut author 000100318410 802002133935 975208259089 0000-0003-4345-8225 UGent Michaël Nicolaï Michaël Nicolaï aut author 802002891545 0000-0002-9570-0311 WE11 Wanjie Xie Wanjie Xie aut author 802003945411 WE11 Maarten Wynant Maarten Wynant aut author 919029536706 Matthew Shawkey Matthew Shawkey aut author 802002093216 0000-0002-5131-8209 WE11 Karen De Clerck Karen De Clerck aut author 801000947425 0000-0002-5650-3075 TW11 Liliana D'Alba Altamirano Liliana D'Alba Altamirano aut author 802002269634 0000-0002-2478-3455 WE11 Department of Biology WE11 sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department 3G0A7921 ae3ff06f-4420-11eb-809b-01df1efbbcb6 2021-01-01 2024-12-31 1540-7063 1557-7023 2024 64 1 107 119 2024 Biology and Life Sciences AMORPHOUS CALCIUM-CARBONATE WATER EXCHANGE EGG CUTICLE MICROSTRUCTURE INCUBATION EVOLUTION ARAGONITE LIZARD GROWTH info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01J00YG8QZ62HKD34KBPVPS5KP/file/01KTVFFD11VAXGBPY747TZM77N info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1524653 bytes accepted_manuscript.pdf https://biblio.ugent.be/publication/01J00YG8QZ62HKD34KBPVPS5KP/file/01KTVFFM9RJ078RDZV1BD9B7JS info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1676778 bytes publisher_version.pdf https://biblio.ugent.be/publication/01J00YG8QZ62HKD34KBPVPS5KP/file/01KTVFGX028PZNMH8XZFZZ8CAQ info:eu-repo/semantics/closedAccess https://www.iana.org/assignments/media-types/application/vnd.openxmlformats-officedocument.wordprocessingml.document fullText http://purl.org/dc/dcmitype/Text 2169081 bytes debruyn_2024_AAM.docx Debruyn, Gerben, Jozefien Geltmeyer, Ella Schoolaert, Michaël Nicolaï, Wanjie Xie, Maarten Wynant, Matthew Shawkey, Karen De Clerck, and Liliana D’Alba Altamirano. 2024. “Hydric Environment and Chemical Composition Shape Non-Avian Reptile Eggshell Absorption.” INTEGRATIVE AND COMPARATIVE BIOLOGY 64 (1): 107–119. doi:10.1093/icb/icae040.

The prevalence, function and nanostructural origin of structural coloration in eggs is largely unknown. Stick and leaf insect eggs display a wide variety of colours, most of which are produced by pigments. The eggs of Myronides glaucus (Phasmida: Lonchodidae; Hennemann, 2021), however, show a clear purple to green iridescence. Here, we use micro-spectrophotometry, Fourier-transform infrared reflectance, transmission- and scanning electron microscopy, atomic force microscopy, finite-difference time-domain optical simulations and experimental approaches to elucidate the mechanism for iridescence in M. glaucus eggshells, which together reveal that iridescence is caused by thin-film interference by a 200- to 450-nm-thick outermost layer. These results highlight the diversity of phasmid eggs and the need to study the different mechanisms and functions of structural coloration. journalArticle original public Article A1 published published ugent 9 Gerben Debruyn Gerben Debruyn aut author 802003560037 WE11 Thies H.

This critical, current challenge in pharmaceutics has led to an increased interest in advanced aqueous solubility-enhancing strategies, with the formulation of amorphous solid dispersions (ASDs) as one of the most promising routes. Here, the active pharmaceutical ingredient is ideally molecularly dispersed in a polymeric carrier, hence increasing its chemical potential with respect to its highly stable crystalline counterpart and improving the thermodynamic driving force for dissolution in the gastrointestinal fluids. Nonetheless, the amount of marketed ASDs is still limited, as many ASDs lack physical stability due to their amorphous nature, and recrystallization to their less soluble state during production, downstream processing, storage, and dissolution often limits the applicability. In this research, an important step is taken towards the bioavailability improvement of poorly water-soluble drugs through the formulation of stable ASDs, with flubendazole (FBZ), itraconazole (ITC), mebendazole (MBZ), and celecoxib (CCX) as known Biopharmaceutics Classification System (BCS) class II model compounds. Solvent electrospinning of a working solution of the drug and poly(2-ethyl-2-oxazoline) is put forward, because of the extremely fast solvent evaporation, which freezes the API in the polymeric carrier in a highly homogeneous manner. This work demonstrates the viability and broad applicability of this strategy to produce stable nanofibrous ASDs with ultrahigh drug loadings (up to 55, 60, 70, and 80 wt% for FBZ, ITC, MBZ, and CCX, respectively) and long-term stability (at least one year). Importantly, at such high drug loadings, lowering the concentration of the polymer in the electrospinning solution below the concentration where it can be spun in the absence of the drug is essential, as the interactions between the polymer and the drug result in an increased solution viscosity. A combination of experimental analysis and molecular dynamics simulations revealed that this formulation strategy provides strong, dominant, and highly stable hydrogen bonds between the polymer and the drug, which is crucial to obtain the high drug loadings and to preserve the long-term amorphous character of the ASDs upon storage. In vitro drug release studies confirm the remarkable potential of this electrospinning formulation strategy by significantly increasing drug solubility values (e.g. up to 50 times for ITC after 5 hours) and dissolution rates, even after one-year storage of the formulations (as tested for FBZ). conference meetingAbstract public C3 published published ugent Olmo Frateur Olmo Frateur aut author 000150886227 802003501433 976840489813 0000-0002-0198-561X TW11 Jana Becelaere Jana Becelaere aut author 977861082888 0000-0001-5024-3308 Chris Vervaet Chris Vervaet aut author 801000867397 973325837380 0000-0002-1291-6054 FW01 Richard Hoogenboom Richard Hoogenboom aut author 802000620432 975196852903 0000-0001-7398-2058 WE07 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Pharmaceutics FW01 sht department Department of Organic and Macromolecular Chemistry WE07 sht department Materials Research Society (MRS) Boston, Massachusetts, USA + Virtual 2023-11-26 2023-12-07 3S002821 4ad519a6-2a81-11ec-a6b4-cd4eac00b947 2021-11-01 2025-10-31 3S000718 d89c7f90-be65-11e9-ace9-8bf558aeac68 2018-01-01 2022-12-31 Materials Research Society (MRS) 2023 SB09.08.09 1000 1001 2023 Technology and Engineering Chemistry info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01HHKSJAXKY6K53AREEXFV198F/file/01HHKT6XEAA3F42XVYB3KP1S68 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 17610433 bytes F23-Abstract-book.pdf https://www.mrs.org/meetings-events/fall-meetings-exhibits/2023-mrs-fall-meeting/symposium-sessions%23program open fullText http://purl.org/dc/dcmitype/InteractiveResource https://www.mrs.org/meetings-events/fall-meetings-exhibits/2023-mrs-fall-meeting open fullText http://purl.org/dc/dcmitype/InteractiveResource https://www.mrs.org/docs/default-source/meetings-events/fall-meetings/2023/f23-abstract-book.pdf?sfvrsn=74480d09_1 open fullText http://purl.org/dc/dcmitype/InteractiveResource Frateur, Olmo, Jana Becelaere, Chris Vervaet, Richard Hoogenboom, and Karen De Clerck. 2023. “Increasing Aqueous Drug Solubility by Solvent Electrospinning of Poly(2-Ethyl-2-Oxazoline) Based Stable Amorphous Solid Dispersions with High Drug Loading.” In 2023 MRS Fall Meeting & Exhibit, Abstracts, 1000–1001.

By lowering the polymer concentration in the electrospinning solution below its individual spinnable limit, ASDs with a drug content of up to 80 wt% are obtained. This is attributed to drug-polymer interactions not being limited by default to hydrogen bonds, as also Van der Waals interactions can result in high drug loadings. The theoretically predicted miscibility by the Flory-Huggins theory is corroborated by the experimental findings based on (modulated) differential scanning calorimetry and x-ray diffraction. Globally, the maximally obtained amorphous drug loadings are higher compared to the loadings found in literature. Additionally, non-sink dissolution tests demonstrate an increase in solubility of up to 50 times compared to their crystalline counterparts. Moreover, due to the lack of precipitation biocompatible PEtOx succeeds in stabilizing the dissolved drug and inhibiting its instant precipitation. The current work thus demonstrates the broader applicability of the electrospinning technique for the production of physically stable ASDs with ultra-high drug loadings, a result which has been validated for several Biopharmaceutics Classification System class II drugs. journalArticle original public Article A1 published published ugent 1 Jana Becelaere Jana Becelaere aut author 977861082888 0000-0001-5024-3308 Olmo Frateur Olmo Frateur aut author 000150886227 802003501433 976840489813 0000-0002-0198-561X TW11 Ella Schoolaert Ella Schoolaert aut author 000100318410 802002133935 975208259089 0000-0003-4345-8225 UGent Valérie Vanhoorne Valérie Vanhoorne aut author 802001047939 977541519725 0000-0003-4249-3408 FW01 Dagmar D'hooge Dagmar D'hooge aut author 802000024082 973689492909 0000-0001-9663-9893 TW11 Chris Vervaet Chris Vervaet aut author 801000867397 973325837380 0000-0002-1291-6054 FW01 Richard Hoogenboom Richard Hoogenboom aut author 802000620432 975196852903 0000-0001-7398-2058 WE07 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Organic and Macromolecular Chemistry WE07 sht department Department of Pharmaceutics FW01 sht department 3S000718 d89c7f90-be65-11e9-ace9-8bf558aeac68 2018-01-01 2022-12-31 3S002821 4ad519a6-2a81-11ec-a6b4-cd4eac00b947 2021-11-01 2025-10-31 0168-3659 1873-4995 2023 362 268 277 2023 Technology and Engineering Amorphous solid dispersions (ASDs) Poly(2-ethyl-2-oxazoline) (PEtOx) Solvent electrospinning Solubility enhancement Poorly soluble drugs Flory-Huggins info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01HA25M3577S3JXMWKYCTN1GGJ/file/01HA25W562MJ0K1ARZA89ZP1HF info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 4147546 bytes 1-s2.0-S0168365923005540-main.pdf https://biblio.ugent.be/publication/01HA25M3577S3JXMWKYCTN1GGJ/file/01HFEX7B8H29WRA1YFNJ6070GG info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 999601 bytes JCR_AAM.pdf Becelaere, Jana, Olmo Frateur, Ella Schoolaert, Valérie Vanhoorne, Dagmar D’hooge, Chris Vervaet, Richard Hoogenboom, and Karen De Clerck. 2023. “Solvent Electrospinning Amorphous Solid Dispersions with High Itraconazole, Celecoxib, Mebendazole and Fenofibrate Drug Loading and Release Potential.” JOURNAL OF CONTROLLED RELEASE 362: 268–277. doi:10.1016/j.jconrel.2023.08.054.

However, little is known about their mechanical performance which could be a limiting factor for further innovation. It is shown in this work that silica nanofiber membranes have a completely different deformation behavior compared to conventional polymeric/thermoplastic nanofiber membranes, resulting from their significant differences in chemical and physical properties such as fiber interactions and porosity. Furthermore, storage at room temperature initiates remarkable changes in failure mechanisms, depending on the storage humidity, which can be accelerated via a thermal treatment. These changes are linked to the structural changes of the membrane resulting from its chemical reactivity towards moisture in the air. Additional interactions and crosslinks are observed, leading to fiber shrinkage and rearrangement. As a result, more contact points are created between nanofibers, creating additional friction forces and, as such, a complete shift in mechanical properties towards a stronger, stiffer, and more brittle material (tensile strength of 14.0 ± 3.8 MPa vs. 3.1 ± 0.4 MPa and failure strain of 0.9 ± 0.2% vs. 24.2 ± 1.0%). The silica nanofiber membranes thus allow mechanical tunability via altering the storage or treatment conditions. journalArticle original public Article A1 published published ugent 2 Bianca Swanckaert Bianca Swanckaert aut author 978889457589 0000-0001-6036-6512 Olivier Verschatse Olivier Verschatse aut author 974442908376 0000-0001-7732-6007 Eva Loccufier Eva Loccufier aut author 802002671374 974161061035 0000-0001-7045-2721 TW11 Klaartje De Buysser Klaartje De Buysser aut author 801001571962 978828372447 0000-0001-7462-2484 WE06 Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Chemistry WE06 sht department 3S039119 9cfd7b5f-f96d-11e9-b85e-e128f57a36f9 2019-11-01 2023-10-31 BOF/STA/202009/046 25182d45-ccf4-11eb-9f0b-e5cd0f711fbd 2021-07-01 2025-06-30 01J10219 1e0c3a2d-9d90-11e9-83f9-d13d95d2d7be 2019-10-01 2024-07-30 0272-8842 1873-3956 2023 49 20 33305 33315 2023 Technology and Engineering Materials Chemistry Surfaces, Coatings and Films Process Chemistry and Technology Ceramics and Composites Electronic, Optical and Magnetic Materials Silica nanofiber membranes Electrospinning Deformation behavior Dynamic info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01H815QS3246S1CHZTW91J8HVX/file/01H816GA0YDQ33MW429JJ0X4TF info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 12600340 bytes 1-s2.0-S0272884223022708-main.pdf https://biblio.ugent.be/publication/01H815QS3246S1CHZTW91J8HVX/file/01H8XYV55QN0B7QYYJKK87D6A8 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1728844 bytes Accepted version research paper.pdf Swanckaert, Bianca, Olivier Verschatse, Eva Loccufier, Klaartje De Buysser, Lode Daelemans, and Karen De Clerck. 2023. “Chemical and Structural Induced Ductile-to-Brittle Transition in Electrospun Silica Nanofiber Membranes.” CERAMICS INTERNATIONAL 49 (20): 33305–33315. doi:10.1016/j.ceramint.2023.08.041.

Elastane increases the functionality during use phase, but impedes high quality recycling. This study investigates the selective chemical dissolution of elastane from blended textile. Hansen solubility parameters and COSMO-RS were applied for solvent screening. The most recommended biobased solvents were experimentally validated with polyester, polyamide, cotton, wool and elastane for which solubility limits were determined and hence, their selectivity towards elastane dissolution. A TGA-corrected gravimetric method was developed as quantification tool and showed that tetrahydrofurfuryl alcohol and ɣ-valerolactone have comparable elastane dissolution capabilities to classical solvents (5 mg elastane/g solvent). Polyester/elastane and polyamide/elastane blends were subjected to this process as case studies. The LCA study showed that this selective solvent-based dissolution process saves 60% CO2-eq./kg textile waste compared to incineration. This interdisciplinary work can set the benchmark for further developing and upscaling physical/dissolution recycling processes for blended textiles. journalArticle original public Article A1 published published ugent 1 Kim Phan Kim Phan aut author 000090124821 802002578620 971260175395 0000-0001-8660-5251 UGent Sibel Ügdüler Sibel Ügdüler aut author 802002808386 974939656288 LA24 Lies Harinck Lies Harinck aut author 802001417650 972688684190 LA24 Ruben Denolf Ruben Denolf aut author 972506839102 0000-0002-1271-0128 UGent Martijn Roosen Martijn Roosen aut author 974623612003 0000-0002-9551-4658 Galahad O'Rourke Galahad O'Rourke aut author Dirk De Vos Dirk De Vos aut author Veronique Van Speybroeck Veronique Van Speybroeck aut author 801001153549 919016668139 976495757166 0000-0003-2206-178X TW17 WE05 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Steven De Meester Steven De Meester aut author 802000481497 973680737243 0000-0002-5246-3918 LA24 Department of Green Chemistry and Technology LA24 sht department Department of Applied physics TW17 sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Physics and astronomy WE05 sht department 179W04520 f1995a99-c029-433b-a853-b5a442d60431 2021-01-01 2023-06-30 179O01221 b51528d2-9881-4147-a897-b706edd5f113 2021-03-01 2022-12-31 HPC-UGent 01-JAN-08 0921-3449 1879-0658 2023 191 106903 2023 Chemistry Textile Recycling Polymers COSMO-RS TGA solvent IONIC LIQUIDS SOLUBILITY PARAMETERS CELLULOSE FABRICS info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01GRR1T4AEYTVZH7BR3VHVQZ6Y/file/01GVFX6KXYPPEGGXTXNR3GAGKN info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 11274087 bytes 1-s2.0-S092134492300040X-main.pdf Phan, Kim, Sibel Ügdüler, Lies Harinck, Ruben Denolf, Martijn Roosen, Galahad O’Rourke, Dirk De Vos, Veronique Van Speybroeck, Karen De Clerck, and Steven De Meester. 2023. “Analysing the Potential of the Selective Dissolution of Elastane from Mixed Fiber Textile Waste.” RESOURCES CONSERVATION AND RECYCLING 191. doi:10.1016/j.resconrec.2023.106903.

Although the currently depicted static expiry, best-by, and due-by dates provide accurate information on when to consume the food product, these time indications are only valid under ideal storage conditions. Therefore, there is a stringent need for easy-to-use sensor applications that allow continuous monitoring of food freshness. This work showcases a straightforward and effortless approach to obtain highly porous cross-linked water-stable and reactive hydrophilic nanofiber membranes based on electrospinning of poly(2-isoproprenyl-2-oxazoline) (PiPOx) with succinic acid as the cross-linker. Subsequent thermal treatment of the produced succinic acid-containing PiPOx nanofiber networks generated sufficient cross-linking to preserve the fibrous morphology in an aqueous environment while retaining the hydrophilic character of the scaffold. The remaining 2-oxazoline side chains of PiPOx are stable at room temperature but provide reactivity for post-cross-linking modification with carboxylic acid-containing compounds, as exploited here for continuous food monitoring by incorporating acid-functionalized dyes to yield a colorimetric sensor for biogenic food spoilage indicators, such as thiol- and amine-containing small molecules. journalArticle original public Article A1 published published ugent 5 Ronald Merckx Ronald Merckx aut author 974260040744 0000-0002-2867-0888 Jana Becelaere Jana Becelaere aut author 977861082888 0000-0001-5024-3308 Ella Schoolaert Ella Schoolaert aut author 000100318410 802002133935 975208259089 0000-0003-4345-8225 UGent Olmo Frateur Olmo Frateur aut author 000150886227 802003501433 976840489813 0000-0002-0198-561X TW11 Meike Leiske Meike Leiske aut author 802003771720 975263848375 UGent Daniël Peeters Daniël Peeters aut author 000160003924 973659654392 Adriana Jerca Adriana Jerca aut author 802003032904 978283456961 UGent Valentin-Victor Jerca Valentin-Victor Jerca aut author 802002296007 973706288659 UGent Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Richard Hoogenboom Richard Hoogenboom aut author 802000620432 975196852903 0000-0001-7398-2058 WE07 Department of Organic and Macromolecular Chemistry WE07 sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department 3S013517 4c4bb546-8208-11e9-8dbc-f3943d565b0b 2017-01-01 2021-03-31 3S000718 d89c7f90-be65-11e9-ace9-8bf558aeac68 2018-01-01 2022-12-31 3S012019 4b38d931-60d8-11e9-aa53-555acf89d448 2019-01-01 2022-12-31 0897-4756 1520-5002 2023 35 17 7079 7093 2023 Chemistry Agriculture and Food Sciences ELECTROSPUN NANOFIBERS POLYMERIC NANOFIBERS BENDING INSTABILITY TIME-TEMPERATURE AQUEOUS-SOLUTION BIOGENIC-AMINES LINKING QUALITY PH POLY(2-ISOPROPENYL-2-OXAZOLINE) info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01HV9GYYHNTRVD30F15P8K01F5/file/01HV9H0D49VDE7G4FR9RY4EJ4H info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1139179 bytes Chem-Mater_PiPOx-nanofiber-sensors-food-monitoring_revised.pdf https://biblio.ugent.be/publication/01HV9GYYHNTRVD30F15P8K01F5/file/01HZPRQX22XW2VFV986SQGNWGP info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 11012788 bytes merckx-et-al-2023-poly(2-isoproprenyl-2-oxazoline)-based-reactive-hydrophilic-cross-linked-nanofiber-networks-as-the.pdf Merckx, Ronald, Jana Becelaere, Ella Schoolaert, Olmo Frateur, Meike Leiske, Daniël Peeters, Adriana Jerca, Valentin-Victor Jerca, Karen De Clerck, and Richard Hoogenboom. 2023. “Poly(2-Isoproprenyl-2-Oxazoline)-Based Reactive Hydrophilic Cross-Linked Nanofiber Networks as the Basis for Colorimetric Continuous Meat Freshness Monitoring Sensors.” CHEMISTRY OF MATERIALS 35 (17): 7079–7093. doi:10.1021/acs.chemmater.3c01355.

Here, a silica nanofibrous membrane is investigated as carrier for Ru nanoparticles, themselves encapsulated inside the metal organic framework (MOF) Cr-MIL-101. The catalytic membrane is investigated for the Sabatier methanation reaction. The direct electrospinning of a tetraorthosilicate (TEOS) sol results in a highly thermal resistant silica nanofibrous structure (up to 1100 degrees C) with pores between the fibers in the mu m-range, allowing a high gas throughput with low pressure requirements. A straightforward dip-coating procedure of the carrier was used to obtain a Ru@MIL-101 functionalized silica nanofibrous veil, avoiding Ru clustering. The obtained catalytic membrane exhibited an apparent turnover frequency of 3257 h-1 at 250 degrees C. This system therefore paves the way towards structured reactors for efficient CO2 hydrogenation processes. journalArticle original public Article A1 published published ugent 1 Eva Loccufier Eva Loccufier aut author 802002671374 974161061035 0000-0001-7045-2721 TW11 Geert Watson Geert Watson aut author 979564449873 0000-0002-2324-4521 UGent Yingrui Zhao Yingrui Zhao aut author Maria Meledina Maria Meledina aut author Robbe Denis Robbe Denis aut author 000130097006 975924966831 Parviz Gohari Derakhshandeh Parviz Gohari Derakhshandeh aut author 979103026230 0000-0001-9655-6019 UGent Pascal Van Der Voort Pascal Van Der Voort aut author 801002082830 978164144941 0000-0002-1248-479X WE06 Karen Leus Karen Leus aut author 802000257185 972695289991 TW17 WE06 Damien P.

However, the recovery and purification of LA from fermentation broths is typically very energy demanding. The in-situ recovery of LA via migration of its lactate anion through an anion-exchange membrane (AEM), combining electrochemical systems with fermentation, offers a viable solution for this. In this work, sustainable silica-based nanofiber AEMs were developed with excellent ionic properties and a strong selectivity for organic acids. Starting from a tetraethoxysilane/chloropropyltriethoxysilane (TEOS/CPTES) sol-gel system, anion conductive nanofiber membranes were obtained via the alkylation of the Csingle bondCl moieties on the electrospun nanofibers with 1-methylimidazole, resulting in an ion-exchange capacity (IEC) of 1.9 ± 0.3 mmol g−1. Post-functionalization with octyltriethoxysilane (OTES) resulted in hydrophobic porous nanofiber AEMs with excellent separation properties. It was shown that the nanofiber AEM had an improved lactate selectivity compared to a commercially dense AEM in the presence of (selectivity of 8.8 vs. 1.1) with an energy consumption of 1.6 kWh kg−1 vs. 3.0 kWh kg−1 for lactate migration, proving its potential as a sustainable material for industrial applications. journalArticle original public Article A1 published published ugent 3 Bianca Swanckaert Bianca Swanckaert aut author 978889457589 0000-0001-6036-6512 Nele Vande Velde Nele Vande Velde aut author 975423503709 Eva Loccufier Eva Loccufier aut author 802002671374 974161061035 0000-0001-7045-2721 TW11 Klaartje De Buysser Klaartje De Buysser aut author 801001571962 978828372447 0000-0001-7462-2484 WE06 Luiza Bonin Luiza Bonin aut author 802002939944 0000-0001-7123-0012 LA25 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Chemistry WE06 sht department Department of Biotechnology LA25 sht department 3S009618 d937d58c-be65-11e9-ace9-8bf558aeac68 2018-01-01 2022-09-09 3S039119 9cfd7b5f-f96d-11e9-b85e-e128f57a36f9 2019-11-01 2023-10-31 01P02520 dab10fe1-0253-11eb-85b3-6fc0ef18aead 2020-10-01 2024-09-30 01J10219 1e0c3a2d-9d90-11e9-83f9-d13d95d2d7be 2019-10-01 2024-07-30 2214-9937 Elsevier BV 2023 38 e00758 2023 Technology and Engineering Industrial and Manufacturing Engineering Waste Management and Disposal General Materials Science Renewable Energy, Sustainability and the Environment silica nanofibers electrospinning anion-exchange membrane lactid acid recovery electrochemical treatment info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01HEMWXV1H78WNWP4ME0QMM0H1/file/01HEMXAZQ2KP3CCZDQ04FG19NG info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 3902411 bytes 1-s2.0-S2214993723001938-main.pdf https://biblio.ugent.be/publication/01HEMWXV1H78WNWP4ME0QMM0H1/file/01HEQ6CG266YQ8T1K0T7FPFGRW info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 992042 bytes Revised anonymized manuscript - ACCEPTED.pdf Swanckaert, Bianca, Nele Vande Velde, Eva Loccufier, Klaartje De Buysser, Luiza Bonin, and Karen De Clerck. 2023. “High Capacity, Silica-Based Anion-Exchange Nanofiber Membranes for the Selective Recovery of Lactic Acid.” SUSTAINABLE MATERIALS AND TECHNOLOGIES 38. doi:10.1016/j.susmat.2023.e00758.

AIMS procedures are, however, still hampered by both analytical, i.e., matrix effects, and practical, i.e., sample transport stability, drawbacks that impede metabolome coverage. In this study, we aimed at developing biofluid-specific metabolome sampling membranes (MetaSAMPs) that offer a directly applicable and stabilizing substrate for AIMS. Customized rectal, salivary, and urinary MetaSAMPs consisting of electrospun (nano)fibrous membranes of blended hydrophilic (polyvinylpyrrolidone and polyacrylonitrile) and lipophilic (polystyrene) polymers supported metabolite absorption, adsorption, and desorption. Moreover, MetaSAMP demonstrated superior metabolome coverage and transport stability compared to crude biofluid analysis and was successfully validated in two pediatric cohorts (MetaBEAse, n = 234 and OPERA, n = 101). By integrating anthropometric and (patho)physiological with MetaSAMP-AIMS metabolome data, we obtained substantial weight-driven predictions and clinical correlations. In conclusion, MetaSAMP holds great clinical application potential for on-the-spot metabolic health stratification. journalArticle original public Article VABB-1 not-approved A1 published published ugent 3 Margot De Spiegeleer Margot De Spiegeleer aut author 000130754582 974472127810 0000-0002-1088-7245 UZGent Vera Plekhova Vera Plekhova aut author 802002994912 977915818675 0000-0002-6109-7032 DI04 Jozefien Geltmeyer Jozefien Geltmeyer aut author 000070582957 975000449525 0000-0002-1281-2968 Ella Schoolaert Ella Schoolaert aut author 000100318410 802002133935 975208259089 0000-0003-4345-8225 UGent Beata Pomian Beata Pomian aut author 802001060871 972405514922 DI04 Varoon Singh Varoon Singh aut author Kathleen Wijnant Kathleen Wijnant aut author 802002558917 910004446134 0000-0002-8242-4522 GE38 UZGent Kimberly De Windt Kimberly De Windt aut author 000170678267 802004133246 976434719514 0000-0002-9589-5112 DI04 Volter Paukku Volter Paukku aut author 975400966363 0000-0003-1194-4122 Alexander De Loof Alexander De Loof aut author Inge Gies Inge Gies aut author Nathalie Michels Nathalie Michels aut author 802000659030 971022391922 0000-0002-3069-7254 PP07 Stefaan De Henauw Stefaan De Henauw aut author 801000760293 971658810740 0000-0003-4141-5432 GE39 Marilyn De Graeve Marilyn De Graeve aut author 971668236009 0000-0001-6916-401X UGent Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Lynn Vanhaecke Lynn Vanhaecke aut author 801001950969 976961995245 0000-0003-0400-2188 DI04 Department of Translational Physiology, Infectiology and Public Health DI04 sht department Department of Public Health and Primary Care GE39 sht department Department of developmental, personality and social psychology PP07 sht department 3S034519 9c7697d7-f96d-11e9-b85e-e128f57a36f9 2019-11-01 2023-09-30 3F012219 9d6032b0-f64e-11e9-ae31-3be9d515fa23 2019-11-01 2024-03-04 3G0G0119 b6fbf4de-7f84-4ae3-b8cb-3d52ba2838a8 2019-02-01 2023-01-31 01GB0217 fc13ecf2-c6a3-4dfc-af18-9cd071dcd618 2017-01-01 2023-12-31 01J07519 1dea5a38-9d90-11e9-83f9-d13d95d2d7be 2019-10-01 2024-07-30 319103418 110e1acb-0560-446c-8cb7-cdc20959e9d0 2018-05-01 2022-04-30 F2020/IOF-StarTT/066 55dc1171-bf61-11ea-8c04-77b709f2f7d3 2020-08-01 2022-07-31 2375-2548 American Association for the Advancement of Science (AAAS) 2023 9 23 2023 Medicine and Health Sciences Multidisciplinary ASSISTED LASER DESORPTION/IONIZATION IONIZATION MASS-SPECTROMETRY FECAL METABOLOME ION DESORPTION CHILDREN WEIGHT HUMANS INDEX info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01H2WM9ZBP36BZ136NHBHN8D4N/file/01H8P1S93JHSFV05DPAVQWTRJE info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 3030124 bytes published article.pdf De Spiegeleer, Margot, Vera Plekhova, Jozefien Geltmeyer, Ella Schoolaert, Beata Pomian, Varoon Singh, Kathleen Wijnant, Kimberly De Windt, Volter Paukku, Alexander De Loof, Inge Gies, Nathalie Michels, Stefaan De Henauw, Marilyn De Graeve, Karen De Clerck, and Lynn Vanhaecke. 2023. “Point-of-Care Applicable Metabotyping Using Biofluid-Specific Electrospun MetaSAMPs Directly Amenable to Ambient LA-REIMS.” SCIENCE ADVANCES 9 (23). doi:10.1126/sciadv.ade9933.

Nevertheless, knowledge of the mechanical behavior, and more specifically, the deformation of nanofiber membranes is still limited today which can complicate the appliance of nanofiber membranes in applications where they are mechanically loaded. In this paper, we, therefore, analyzed the mechanical behavior of polymeric nanofiber membranes with different fiber orientations (random and aligned) extensively. Polyamide 6 was used as a representative reference polymer for proof-of-concept. Mechanical tests show that all membranes have a coherent deformation behavior at the macroscale up to the point of fracture. Large variations in stiffness, ultimate strength, and ultimate strain were observed between membranes with different fiber orientations (Random: E-mod: 370 ± 34 MP; UTS: 38.5 ± 6.0 MPa; εmax: 30.0 ± 2.8%; Parallel aligned: E-mod: 753 ± 11 MPa; UTS: 55.4 ± 0.8 MPa; εmax: 12.0 ± 0.1%; Perpendicular aligned: E-mod: 24.1 ± 3.7 MPa; UTS:/; εmax: &gt;40%). This shows the versatility and tunability of the mechanical behavior of these nanofiber membranes. At the microscale, the fibrous structure results in deformation mechanisms that resist failure formation and progression when the membrane is mechanically loaded. This results in a high fracture resistance, even for pre-damaged membranes. Realignment of the fibers along the loading direction causes crack tip blunting, locally reinforcing the membrane. journalArticle original public Article A1 published published ugent 4 Olivier Verschatse Olivier Verschatse aut author 974442908376 0000-0001-7732-6007 Eva Loccufier Eva Loccufier aut author 802002671374 974161061035 0000-0001-7045-2721 TW11 Bianca Swanckaert Bianca Swanckaert aut author 978889457589 0000-0001-6036-6512 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department 3S009618 d937d58c-be65-11e9-ace9-8bf558aeac68 2018-01-01 2022-09-09 3S039119 9cfd7b5f-f96d-11e9-b85e-e128f57a36f9 2019-11-01 2023-10-31 3E016519 3c0a4b92-b36f-11e9-9b22-19a03077e1f4 2019-10-01 2022-09-30 BOF/STA/202009/046 25182d45-ccf4-11eb-9f0b-e5cd0f711fbd 2021-07-01 2025-06-30 01P03418 b2c0136d-5a95-11e9-b3e1-37a68b033e1d 2019-01-01 2019-09-30 01B03518 320e7057-5b7c-11e9-ac93-1bffacd2a7e2 2018-06-01 2020-05-31 01J10219 1e0c3a2d-9d90-11e9-83f9-d13d95d2d7be 2019-10-01 2024-07-30 2073-4360 2023 15 7 1630 2023 Technology and Engineering Polymers and Plastics General Chemistry mechanical behavior polymeric nanofiber membranes electrospinning in situ SEM analysis info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01H0MBDNBC3GVJ7DECF5ASA3ZG/file/01H0MCSKH1EE4Z7DXR9HRGV6XP info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 3772231 bytes polymers-15-01630.pdf Verschatse, Olivier, Eva Loccufier, Bianca Swanckaert, Karen De Clerck, and Lode Daelemans. 2023. “Microscale and Macroscale Deformation Behavior of Electrospun Polymeric Nanofiber Membranes Using in Situ SEM during Mechanical Testing.” POLYMERS 15 (7). doi:10.3390/polym15071630.

Low chemical resistance and fouling are major issues in the development of next-generation IEMs. Sulfonated silica-based nanofiber cation-exchange membranes (CEMs) offer a promising solution to these issues due to their superior chemical resistance and self-cleaning properties. Via the direct electrospinning of a sol–gel solution starting from tetraethyl orthosilicate (TEOS) and 3-mercaptopropyl triethoxysilane (MPTES), nanofiber membranes with an ion-exchange capacity (IEC) of 1.3 mmol g−1 can be produced without the need of an additional matrix. The produced nanofiber CEM performs excellent in lab-scale electrochemical tests, with a resistance of 3.2 ± 0.4 *10-3 Ω m2 and a Coulombic efficiency of ± 70 % for the transport of Na+ using a current density of either 128 or 256 A/m−2. Furthermore, the nanofiber CEM shows outstanding resistance against strong acidic solutions and chlorine. After fouling of the membrane with CaCO3, the nanofiber CEM shows self-cleaning properties, eliminating the need for an additional cleaning step during usage. These results illustrate the excellent performance of the silica-based nanofiber CEM for industrial water treatment applications. journalArticle original public Article A1 published published ugent 2 Bianca Swanckaert Bianca Swanckaert aut author 978889457589 0000-0001-6036-6512 Eva Loccufier Eva Loccufier aut author 802002671374 974161061035 0000-0001-7045-2721 TW11 Jozefien Geltmeyer Jozefien Geltmeyer aut author 000070582957 975000449525 0000-0002-1281-2968 Korneel Rabaey Korneel Rabaey aut author 801001551956 972717941111 0000-0001-8738-7778 LA25 Klaartje De Buysser Klaartje De Buysser aut author 801001571962 978828372447 0000-0001-7462-2484 WE06 Luiza Bonin Luiza Bonin aut author 802002939944 0000-0001-7123-0012 LA25 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Biotechnology LA25 sht department Department of Chemistry WE06 sht department 3S039119 9cfd7b5f-f96d-11e9-b85e-e128f57a36f9 2019-11-01 2023-10-31 01J10219 1e0c3a2d-9d90-11e9-83f9-d13d95d2d7be 2019-10-01 2024-07-30 01P02520 dab10fe1-0253-11eb-85b3-6fc0ef18aead 2020-10-01 2024-09-30 1383-5866 1873-3794 2023 309 123001 2023 Technology and Engineering Chemistry Filtration and Separation Analytical Chemistry Silica nanofibers Cation-exchange membrane Self-cleaning Fouling Electrochemical water treatment ADVANCED OXIDATION PROCESSES ION-EXCHANGE CERAMIC NANOFIBERS FUEL-CELL ELECTRODIALYSIS PERFORMANCE SELECTIVITY ENERGY TECHNOLOGIES TEMPERATURE info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01GPJZY6YJZ4FEDGFG3CYS1R86/file/01GPK143G37DJPFQ0BPH3GMTVG info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 7073399 bytes 1-s2.0-S1383586622025588-main.pdf https://biblio.ugent.be/publication/01GPJZY6YJZ4FEDGFG3CYS1R86/file/01GR3Z0PPWC0GZJ0S62R69HMHS info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1306515 bytes Research paper nanofiber CEM_accepted version.pdf Swanckaert, Bianca, Eva Loccufier, Jozefien Geltmeyer, Korneel Rabaey, Klaartje De Buysser, Luiza Bonin, and Karen De Clerck. 2023. “Sulfonated Silica-Based Cation-Exchange Nanofiber Membranes with Superior Self-Cleaning Abilities for Electrochemical Water Treatment Applications.” SEPARATION AND PURIFICATION TECHNOLOGY 309. doi:10.1016/j.seppur.2022.123001.

Yet, the application of a high-quality speckle pattern for DIC remains challenging at this scale. Here, we present a versatile polymer particle-based speckle pattern with adjustable speckle size (0.17–1.04 μm) to cover a wide range of magnifications (500x to 5000x) in SEM. This speckle does not completely cover the surface, ensuring the visibility of deformations taking place in the studied object. The quality of the pattern is analyzed to determine the precision, noise, and correctness of the results obtained by SEM-DIC. Out-of-plane displacements are also considered. Depending on the choice of speckle size and imaging parameters, high quality SEM-DIC patterns were obtained. The measurable strain with this method ranges between 0.05% up to 100%. To illustrate the versatility of the speckling method, three different micromechanical test cases on polymer materials are presented. These showed that global and local deformation can clearly be visualized at different magnifications. journalArticle original public Article A1 published published ugent 1 Olivier Verschatse Olivier Verschatse aut author 974442908376 0000-0001-7732-6007 Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department BOF/STA/202009/046 25182d45-ccf4-11eb-9f0b-e5cd0f711fbd 2021-07-01 2025-06-30 01B03518 320e7057-5b7c-11e9-ac93-1bffacd2a7e2 2018-06-01 2020-05-31 01P03418 b2c0136d-5a95-11e9-b3e1-37a68b033e1d 2019-01-01 2019-09-30 01J10219 1e0c3a2d-9d90-11e9-83f9-d13d95d2d7be 2019-10-01 2024-07-30 3E016519 3c0a4b92-b36f-11e9-9b22-19a03077e1f4 2019-10-01 2022-09-30 0142-9418 1873-2348 2023 125 108134 2023 Technology and Engineering Polymers and Plastics Organic Chemistry SEM-DIC Micromechanical testing Polymers Epoxy info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01H83X216DE0QB0N98CDXHR419/file/01H83XVGAJNQPFW9WQHTW3BX8P info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 17963747 bytes 1-s2.0-S0142941823002143-main.pdf Verschatse, Olivier, Wim Van Paepegem, Karen De Clerck, and Lode Daelemans. 2023. “Development of a Versatile Speckle Pattern of Nano-Sized Polymer Particles for High-Resolution SEM-DIC.” POLYMER TESTING 125. doi:10.1016/j.polymertesting.2023.108134.

The chemical kinetics are although poorly understood, due to a lack of Arrhenius parameters and a focus on kinetic data mainly recorded at 298 K. The present work overcomes these shortcomings by reporting Arrhenius parameters for the most important reactions (hydrolysis and condensation), selecting tetraethyl orthosilicate (TEOS) crosslinking with hydrochloric acid (HCl) as reference case. A dedicated 29Si nuclear magnetic resonance (NMR) protocol applicable at any process temperature, with better relaxation delay optimization, peak identification, and an automated correction for further reaction during analysis at 298 K, is put forward. NMR is the analysis technique of choice to quantitatively follow the reactions in time due to its high specificity. This novel NMR-based protocol enables a more reliable quantification of the contribution of species that have been crosslinked i times (Q1-Q4). The tuned Arrhenius parameters, employing coupled matrixbased Monte Carlo simulations, can describe the isothermal kinetics for temperatures ranging from 298 to 328 K well. Moreover, these Arrhenius parameters are used to better understand the non-isothermal kinetics as utilized to synthesize sol/gel-like precursor solutions for applications including membrane production. Successful model validation under both isothermal and non-isothermal conditions is demonstrated, unlocking the door to a better understanding of orthosilicate crosslinking kinetics and associated material properties. journalArticle original public Article A1 published published ugent 1 Sofie Verschraegen Sofie Verschraegen aut author 000150868746 802003501534 919029486586 975200255882 0000-0002-6164-3662 TW11 Eva Loccufier Eva Loccufier aut author 802002671374 974161061035 0000-0001-7045-2721 TW11 Lies De Keer Lies De Keer aut author 000100481791 802002106754 971930032541 0000-0003-2620-0046 Paul Van Steenberge Paul Van Steenberge aut author 802000264461 975633424843 0000-0001-6244-1299 TW11 Klaartje De Buysser Klaartje De Buysser aut author 801001571962 978828372447 0000-0001-7462-2484 WE06 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Dagmar D'hooge Dagmar D'hooge aut author 802000024082 973689492909 0000-0001-9663-9893 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Chemistry WE06 sht department 3F006621 190fbf11-2a82-11ec-95aa-05ef7abe0c3c 2021-11-01 2025-10-31 01J10219 1e0c3a2d-9d90-11e9-83f9-d13d95d2d7be 2019-10-01 2024-07-30 3G0H5216N 81ae10a4-560e-42f3-811a-d3ce6f4e3d53 2016-05-01 2020-04-30 3G0H5216 059703ae-9e91-49c6-979a-5d2166f181db 2016-05-01 2020-04-30 1385-8947 1873-3212 2023 461 141701 2023 Chemistry Technology and Engineering Industrial and Manufacturing Engineering General Chemical Engineering Environmental Chemistry General Chemistry info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01GTBNMWFSAPBGCTD45HE8XXKG/file/01GTBPMCFB0BY8N0THEW70KBRQ info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 5398522 bytes 1-s2.0-S1385894723004321-main.pdf https://biblio.ugent.be/publication/01GTBNMWFSAPBGCTD45HE8XXKG/file/01GTE7Y6BW76JFQZHXTGJY405D info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/zip fullText http://purl.org/dc/dcmitype/Text 5700729 bytes SV_CEJ_Manuscript_Main.docx https://biblio.ugent.be/publication/01GTBNMWFSAPBGCTD45HE8XXKG/file/01GTE80E3P18S2KW7EAJHYSR2S info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/zip dataset http://purl.org/dc/dcmitype/Dataset 1190844 bytes SV_CEJ_Manuscript_SI.docx Verschraegen, Sofie, Eva Loccufier, Lies De Keer, Paul Van Steenberge, Klaartje De Buysser, Karen De Clerck, and Dagmar D’hooge. 2023. “A Dedicated Protocol to Capture Orthosilicate Crosslinking Kinetics and Arrhenius Parameters.” CHEMICAL ENGINEERING JOURNAL 461. doi:10.1016/j.cej.2023.141701.

Here, the study reports on switchable optical gain based on complex arrays of nanofibers made of thermo-responsive poly(2-n-propyl-2-oxazoline), incorporating a blue-emitting chromophore. The fluorescent component endows the nanofibers with optical gain in addition to the moisture absorption capability of the polymer. Light amplification is found with temperature- and humidity-dependent excitation threshold. The threshold value is halved close to the polymer cloud point temperature, enabling reversible switching of the emission intensity upon temperature change. Waveguiding analysis by back-focal plane imaging on individual fibers allows the switching mechanisms to be rationalized, in terms of moisture sorption swelling-induced morphological changes. These responsive light-emitting nanofibers may find application in a novel class of lasers with dynamically-controlled properties, environmentally-switchable optoelectronics, and smart sensors. journalArticle original public Article A1 published published ugent 2 Matteo Archimi Matteo Archimi aut author Ella Schoolaert Ella Schoolaert aut author 000100318410 802002133935 975208259089 0000-0003-4345-8225 UGent Jana Becelaere Jana Becelaere aut author 977861082888 0000-0001-5024-3308 Richard Hoogenboom Richard Hoogenboom aut author 802000620432 975196852903 0000-0001-7398-2058 WE07 Andrea Camposeo Andrea Camposeo aut author Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Dario Pisignano Dario Pisignano aut author Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Organic and Macromolecular Chemistry WE07 sht department 3S013517 4c4bb546-8208-11e9-8dbc-f3943d565b0b 2017-01-01 2021-03-31 3S000718 d89c7f90-be65-11e9-ace9-8bf558aeac68 2018-01-01 2022-12-31 3G060518 68c7d40e-8a7e-479e-8231-436053702888 2018-01-01 2021-12-31 2195-1071 2023 11 13 2202056 2023 Technology and Engineering ELECTROSPUN NANOFIBERS HUMIDITY LASER POLY(2-OXAZOLINE)S TEMPERATURE EMISSION POLYMERS DESIGN hygroscopic polymers light-emitting nanofibers nanofiber networks nanofibers optical gain stimuli-responsive materials thermo-responsive polymers info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01H9G348R6MCXQFG8P2Y3593Y4/file/01H9G3KGREFMH4SMY12PHD12ET info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 2965872 bytes Advanced Optical Materials - 2023 - Archimi.pdf https://biblio.ugent.be/publication/01H9G348R6MCXQFG8P2Y3593Y4/file/01HA9Z7R5D2CKAN153A2S6Y6HN info:eu-repo/semantics/closedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 2508995 bytes Paper_Archimi_revised.pdf Archimi, Matteo, Ella Schoolaert, Jana Becelaere, Richard Hoogenboom, Andrea Camposeo, Karen De Clerck, and Dario Pisignano. 2023. “Optical Gain Switching by Thermo-Responsive Light-Emitting Nanofibers through Moisture Sorption Swelling.” ADVANCED OPTICAL MATERIALS 11 (13). doi:10.1002/adom.202202056.

Previous research has shown that providing a microenvironment similar to in vivo settings improves tissue regeneration. Therefore, in this work, ingenious multicomponent nanoyarn scaffolds that mimic the fibrillar and tubular structures of tendons are developed for the first time through electrospinning and bundling nanoyarns followed by electrospinning of a nanofibrous shell around the bundle. Multicomponent nanoyarn scaffolds out of poly(ε-caprolactone) with varying porosity, density, and diameter were successfully produced by coelectrospinning with water-soluble poly(2-ethyl-2-oxazoline) as a sacrificial component. The diameter and fiber orientation of the nanoyarns were successfully tuned based on parameter-morphology models obtained by the design of experiments. Cyclic bending tests were performed, indicating that the flexibility of the multicomponent nanoyarn scaffolds depends on the morphology and can be tuned through controlling the number of nanoyarns in the bundle and the porosity. Indirect and direct cell culture tests using mouse and equine tendon cells revealed excellent cytocompatibility of the nanofibrous products and demonstrated the potential of the nanoyarns to guide the growing cells along the nanofiber direction, which is crucial for tendon tissue engineering. journalArticle original public Article A1 published published ugent 4 Lucas Schynkel Lucas Schynkel aut author 000170347659 802004139815 971311457679 0000-0003-2488-2303 TW11 Marguerite Meeremans Marguerite Meeremans aut author 000140353643 802003490622 978088211826 0000-0003-1521-3378 DI04 Anna A.

Humidity-dependent colour change can occur through either morphological change (e.g. to feather barbules in birds) or by the replacement of air bywater causing a shift in refractive index, as seen in arthropod multi-layer cuticles or scales. The scaled springtail Lepidocyrtus cyaneus has scales that produce colour largely via thin film interference from their lamina. We observed a marked colour change from golden to violet/purple coloration in humid conditions. Light microscopy, micro-spectrophotometry, contact angle goniometry and optical modelling indicate that the formation of a thin film of water on top of the hydrophilic scales increases their laminar thin film thickness, causing a shift towards violet/purple colour. Evaporation of thewater film causes the metallic golden colour to return. This constitutes a remarkably rapid colour change (in the order of seconds), only limited by the speed of water film condensation and evaporation, that may serve as inspiration for new dynamically coloured materials and sensors. journalArticle original public Article A1 published published ugent 7 Bram Vanthournout Bram Vanthournout aut author 975403013164 UGent Frans Janssens Frans Janssens aut author Gerben Debruyn Gerben Debruyn aut author 802003560037 WE11 Johan Mertens Johan Mertens aut author 978235956061 UGent Karen De Clerck Karen De Clerck aut author 801000947425 0000-0002-5650-3075 TW11 Liliana D'Alba Altamirano Liliana D'Alba Altamirano aut author 802002269634 0000-0002-2478-3455 WE11 Matthew Shawkey Matthew Shawkey aut author 802002093216 0000-0002-5131-8209 WE11 Department of Biology WE11 sht department 3G0A7921 ae3ff06f-4420-11eb-809b-01df1efbbcb6 2021-01-01 2024-12-31 1742-5689 1742-5662 2023 20 207 20230228 2023 Biology and Life Sciences Biomedical Engineering Biochemistry Biomaterials Bioengineering Biophysics Biotechnology Collembola humidity-dependent colour change scale spectrophotometry optical modelling MORPHOLOGY SPIDERS CUTICLE info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01HMXJ84F1Z7V71KJMX1APM5EF/file/01KV54MK2T96ADW4CYWWMW1827 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1617392 bytes accepted_manuscript.pdf https://biblio.ugent.be/publication/01HMXJ84F1Z7V71KJMX1APM5EF/file/01KV54MSW9R6E59K29RB0PZSRF info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1319887 bytes publisher_version.pdf https://biblio.ugent.be/publication/01HMXJ84F1Z7V71KJMX1APM5EF/file/01KV54N1DYTFFARFQP5MHP4QY2 info:eu-repo/semantics/closedAccess https://www.iana.org/assignments/media-types/application/vnd.openxmlformats-officedocument.wordprocessingml.document fullText http://purl.org/dc/dcmitype/Text 5896268 bytes Vanthournout_2023_AAM.docx Vanthournout, Bram, Frans Janssens, Gerben Debruyn, Johan Mertens, Karen De Clerck, Liliana D’Alba Altamirano, and Matthew Shawkey. 2023. “Rapid and Reversible Humidity-Dependent Colour Change by Water Film Formation in a Scaled Springtail.” JOURNAL OF THE ROYAL SOCIETY INTERFACE 20 (207). doi:10.1098/rsif.2023.0228.

Electrochemical treatments in (waste)water management show high potential in the global water resource crisis, but are often limited by the performance of the ion-exchange membrane (IEM)[1]. Low chemical resistance and fouling are major issues in the development of the next generation IEMs. An interesting choice of material for IEMs is the use of nanofibers due to their outstanding ionic properties as a result of their specific morphology. Nanofiber membranes are known to have a large specific surface area, flexibility, high porosity and interconnected pores. Different strategies are applied for the production and structural design of these ion-exchange nanofiber membranes. Nanofibers with an ion-exchange functionality can be produced by either pre- or post-functionalization methods, combined with electrospinning. Depending on the application, these nanofiber mats can be used as such, or further membrane processing is possible to improve the dimensional stability, typically by adding a pore-filling matrix in between the nanofibers. By producing IEMs from hybrid nanofibrous membranes containing both organic and inorganic parts, a wide range of different membrane properties can be obtained by altering the molecular structure. This results in IEMs with high thermal and chemical resistance as well as tunability towards a.o. mechanical properties and hydrophobicity for the use in harsh environmental conditions. For example, sulfonated silica-based nanofiber cation-exchange membranes (CEMs) offer a promising solution to the current issues of IEMs, due to their superior chemical resistance and self-cleaning properties. conference meetingAbstract public C3 published published ugent Bianca Swanckaert Bianca Swanckaert aut author 978889457589 0000-0001-6036-6512 Jozefien Geltmeyer Jozefien Geltmeyer aut author 000070582957 975000449525 0000-0002-1281-2968 Korneel Rabaey Korneel Rabaey aut author 801001551956 972717941111 0000-0001-8738-7778 LA25 Klaartje De Buysser Klaartje De Buysser aut author 801001571962 978828372447 0000-0001-7462-2484 WE06 Luiza Bonin Luiza Bonin aut author 802002939944 0000-0001-7123-0012 LA25 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Biotechnology LA25 sht department Department of Chemistry WE06 sht department Fiber Society ; KU Leuven Leuven, Belgium 2022-05-30 2022-06-01 2022 2022 Technology and Engineering info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8755131/file/8755133 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 73717 bytes Fiber_Society_2022_abstract_Bianca_Swanckaert.pdf https://www.mtm.kuleuven.be/english/events/fiber-society-conference-22 open fullText http://purl.org/dc/dcmitype/InteractiveResource Swanckaert, Bianca, Jozefien Geltmeyer, Korneel Rabaey, Klaartje De Buysser, Luiza Bonin, and Karen De Clerck. 2022. “Ion-Exchange Nanofiber Membranes for Advanced Water Treatment Applications.” In The Fiber Society’s Spring 2022 Conference, Abstracts.

Here, we propose dual-mode photonic designs (a static and a dynamic one), which modulate the emissivity to provide thermal regulation in both cold and hot environments. The first design is a Janus-yarn fabric that tunes statically via fabric flipping, while the second design is dynamic by utilizing a shape-memory polymer. conference proceedingsPaper public C1 published published ugent Muluneh G.

Here, a silica nanofibrous membrane is investigated as carrier for Ru nanoparticles, themselves encapsulated inside the metal organic framework Cr-MIL-101. The catalytic membrane is investigated for the Sabatier methanation reaction. The direct electrospinning of a tetraorthosilicate sol-gel system results in a highly thermal resistant silica nanofibrous structure (up to 1100°C) with a large amount of pores between the fibers in the µm-range, allowing a high gas throughput with low pressure requirements. A straightforward dip-coating procedure of the carrier was used to obtain a Ru@MIL-101 functionalized silica nanofibrous veil, avoiding Ru clustering. The obtained catalytic membrane exhibited an apparent turnover frequency of 3257 h-1 at 250°C. This system therefore paves the way towards structured reactors for efficient CO2 hydrogenation processes. conference poster public C3 published published ugent Eva Loccufier Eva Loccufier aut author 802002671374 974161061035 0000-0001-7045-2721 TW11 Geert Watson Geert Watson aut author 979564449873 0000-0002-2324-4521 UGent Yingrui Zhao Yingrui Zhao aut author Maria Meledina Maria Meledina aut author Pascal Van Der Voort Pascal Van Der Voort aut author 801002082830 978164144941 0000-0002-1248-479X WE06 Damien Debecker Damien Debecker aut author Dagmar D'hooge Dagmar D'hooge aut author 802000024082 973689492909 0000-0001-9663-9893 TW11 Klaartje De Buysser Klaartje De Buysser aut author 801001571962 978828372447 0000-0001-7462-2484 WE06 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Chemistry WE06 sht department Ghent, Belgium 2022-10-28 2022-10-28 2022 2022 Technology and Engineering info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01GMVB30NQ8WSC1CQYA0881359/file/01GMXFTCQQ5TXSBCXY39W66JSH info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1299448 bytes fears_2022_poster.pdf Loccufier, Eva, Geert Watson, Yingrui Zhao, Maria Meledina, Pascal Van Der Voort, Damien Debecker, Dagmar D’hooge, Klaartje De Buysser, and Karen De Clerck. 2022. “Inorganic Membranes Allow for a More Clever Use of Nanoparticles as CO2 Conversion Catalyst.” In Faculty of Engineering and Architecture Research Symposium 2022 (FEARS 2022), Abstracts. doi:10.5281/zenodo.7406152.

Electrochemical treatments in (waste)water management show high potential in the global water resource crisis, but are often limited by the performance of the ion-exchange membrane (IEM). Low chemical resistance and fouling are major issues in the development of the next generation IEMs. An interesting choice of material for IEMs is the use of nanofibers due to their outstanding ionic properties as a result of their specific morphology. Nanofiber membranes are known to have a large specific surface area, flexibility, high porosity and interconnected pores. Different strategies are applied for the production and structural design of these ion-exchange nanofiber membranes. Nanofibers with an ion-exchange functionality can be produced by either pre- or post-functionalization methods, combined with electrospinning. Depending on the application, these nanofiber mats can be used as such, or further membrane processing is possible to improve the dimensional stability, typically by adding a pore-filling matrix in between the nanofibers. By producing IEMs from hybrid nanofibrous membranes containing both organic and inorganic parts, a wide range of different membrane properties can be obtained by altering the molecular structure. This results in IEMs with high thermal and chemical resistance as well as tunability towards a.o. mechanical properties and hydrophobicity for the use in harsh environmental conditions. For example, sulfonated silica-based nanofiber cation-exchange membranes (CEMs) offer a promising solution to the current issues of IEMs, due to their superior chemical resistance and self-cleaning properties. conference poster public C3 published published ugent Bianca Swanckaert Bianca Swanckaert aut author 978889457589 0000-0001-6036-6512 Jozefien Geltmeyer Jozefien Geltmeyer aut author 000070582957 975000449525 0000-0002-1281-2968 Korneel Rabaey Korneel Rabaey aut author 801001551956 972717941111 0000-0001-8738-7778 LA25 Klaartje De Buysser Klaartje De Buysser aut author 801001571962 978828372447 0000-0001-7462-2484 WE06 Luiza Bonin Luiza Bonin aut author 802002939944 0000-0001-7123-0012 LA25 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Biotechnology LA25 sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Chemistry WE06 sht department Ghent, Belgium 2022-10-28 2022-10-28 2022 2022 Technology and Engineering info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01GMVB3AEXSKFSQX7AK4SGHAHR/file/01GMXFFM2YTHKXGTV1Z66F9DMN info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 483382 bytes fears_2022_poster.pdf Swanckaert, Bianca, Jozefien Geltmeyer, Korneel Rabaey, Klaartje De Buysser, Luiza Bonin, and Karen De Clerck. 2022. “Ion-Exchange Nanofiber Membranes for Advanced Water Treatment Applications.” In Faculty of Engineering and Architecture Research Symposium 2022 (FEARS 2022), Abstracts. doi:10.5281/zenodo.7406026.

Their high crystallinity prevents any active ingredients from entering our system. For this reason, increasing the aqueous solubility of poorly soluble drugs is highly researched. Solvent electrospinning of a solution of the flubendazole and poly(2-ethyl-2-oxazoline) is demonstrated to be a viable strategy to produce stable nanofibrous amorphous solid dispersions with ultrahigh drug-loadings (up to 55 wt\% flubendazole). Importantly, at such high drug loadings, the concentration of the polymer in the electrospinning solution has to be lowered below the concentration where it can be spun in absence of the drug as the interactions between the polymer and the drug result in increased solution viscosity. X-ray diffraction results and in vitro drug release studies confirm the remarkable amorphous stability and potential of this electrospinning formulation strategy by significantly increased drug solubility values and dissolution rates even after storing the formulation for one year. conference poster public C3 published published ugent Jana Becelaere Jana Becelaere aut author 977861082888 0000-0001-5024-3308 Elias Van Den Broeck Elias Van Den Broeck aut author 971635909747 0000-0002-9609-4333 UGent Veronique Van Speybroeck Veronique Van Speybroeck aut author 801001153549 919016668139 976495757166 0000-0003-2206-178X TW17 WE05 Chris Vervaet Chris Vervaet aut author 801000867397 973325837380 0000-0002-1291-6054 FW01 Richard Hoogenboom Richard Hoogenboom aut author 802000620432 975196852903 0000-0001-7398-2058 WE07 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Applied physics TW17 sht department Department of Pharmaceutics FW01 sht department Department of Organic and Macromolecular Chemistry WE07 sht department Ghent, Belgium 2022-10-28 2022-10-28 2022 2022 Technology and Engineering info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01GMVB2VRSG40997DK22NHW2WK/file/01GMXJADMDC5QAMNK6NYXRWWN3 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 924450 bytes fears_2022_poster.pdf Becelaere, Jana, Elias Van Den Broeck, Veronique Van Speybroeck, Chris Vervaet, Richard Hoogenboom, and Karen De Clerck. 2022. “Improving Flubendazole Efficiency through Time-Stable Electrospun Amorphous Solid Dispersions.” In Faculty of Engineering and Architecture Research Symposium 2022 (FEARS 2022), Abstracts. doi:10.5281/zenodo.7406006.

And yet, sacrificing sample preparation and separation techniques in favor of short analytical run times allows matrix effects to resurface unabated, leading to a decrease in sensitivity accompanied by repeatability and reproducibility issues. In this study, we introduce electrospun polymeric fibrous membranes (MetaSAMPs) for the sampling and direct analysis of biofluids using the established laser-assisted rapid evaporative mass spectrometry (LA-REIMS) methodology (Plekhova et al., Nat.Prot., 2021). By applying customized MetaSAMPs® as a sampling tool and direct substrate for LA-REIMS analysis, we aim to increase the short- and long-term preservation of the metabolome, reduce the impact of macromolecules during analysis while improving metabolome coverage and reproducibility. METHODS Polymeric fibrous sampling membranes (MetaSAMP) were developed by electrospinning with their composition individually optimized for three commonly addressed in light of clinical biochemistry biofluids, i.e. stool, urine and saliva. During validation experiments, pooled biological samples were analyzed as such or impregnated on the MetaSAMP® membranes to compare LA-REIMS signal intensity, metabolome coverage, and reproducibility. Next, the short- and long-term stability were examined by storing the impregnated MetaSAMP® membranes and crude biofluids at 4°C and 20° for 48 hours, or at -20°C and -80°C for up to six weeks. Finally, the clinical applicability of the three biofluid-specific MetaSAMPs® was verified in different pediatric cohorts, i.e. OPERA (n = 95, saliva, 6-16y) and MetaBEAse (n = 76, stool, 6-12y) studying adolescent and childhood obesity and CMA (n = 70, urine, 6 months-3y) studying infant food allergy. PRELIMINARY DATA Based on metabolome coverage, reproducibility and fiber network quality, the optimal urinary MetaSAMP® composition was determined to be a blend of 70/20/10 Polystyrene (PS)/Polyvinylpyrrolidone(PVP)/Polyacrylonitrile(PAN)%, enabling extraction of a broad range of metabolites (log P = -5 to 13). The addition of an outer 10% (w/w) nanofiber PAN coating promoted urine absorption while simultaneously acting as a filter to reduce macromolecule biofouling. Similarly, the optimal compositions of the salivary and rectal MetaSAMPs® were determined as 90/10 PS/PVP and 60/40 PVP/PS, respectively, both with PAN coating. In subsequent validation experiments, impregnated MetaSAMPs showed a higher number of detected metabolic features compared to the crude biofluids whilst maintaining good repeatability with 97%, 66% and 65% of features ≤ 30% CV threshold for the urinary, salivary and rectal MetaSAMP®. After 48h storage, mimicking the maximum transportation time from the patient's home or physician’s office to the laboratory, more metabolic features showed better stability when stored impregnated on the samplers as compared to the raw biofluids, as estimated by the interclass correlation coefficients (ICC). For example, 107 and 732 features detected in urine after storage at 20°C and 4°C, respectively, correlated well between 0 and 48h (ICC > 0.4), while urine impregnated on the MetaSAMP stored at the same conditions generated 1597 and 1851 features with ICCs > 0.4. A similar trend was observed following 6 weeks of storage, as urinary MetaSAMPs still retained 1206 highly correlated features at -20°C, while in urine only 780 remained stable. Lastly, the clinical validation in three independent cohorts showed better predictive power of multivariate OPLS-DA models based on metabolic fingerprints obtained with the MetaSAMPs® , e.g. Q2Y= 0.65 and p-value = 1.3e-11 for urinary MetaSAMP® whereas Q2 Y = 0.52 and p-value = 3.6e-7 for the analysis of crude urinary samples.

These fiber reinforcements allow for the improvement of the mechanical properties, but compared to traditionally produced composite materials, the fiber volume fraction often remains low. This study aims to evaluate the in-nozzle impregnation of continuous aramid fiber reinforcement with glycol-modified polyethylene terephthalate (PETG) using a modified, low-cost, tabletop 3D printer. We analyze how dimensional printing parameters such as layer height and line width affect the fiber volume fraction and fiber dispersion in printed composites. By varying these parameters, unidirectional specimens are printed that have an inner structure going from an array-like to a continuous layered-like structure with fiber loading between 20 and 45 vol%. The inner structure was analyzed by optical microscopy and Computed Tomography (µCT), achieving new insights into the structural composition of printed composites. The printed composites show good fiber alignment and the tensile modulus in the fiber direction increased from 2.2 GPa (non-reinforced) to 33 GPa (45 vol%), while the flexural modulus in the fiber direction increased from 1.6 GPa (non-reinforced) to 27 GPa (45 vol%). The continuous 3D reinforced specimens have quality and properties in the range of traditional composite materials produced by hand lay-up techniques, far exceeding the performance of typical bulk 3D-printed polymers. Hence, this technique has potential for the low-cost additive manufacturing of small, intricate parts with substantial mechanical performance, or parts of which only a small number is needed. journalArticle original public Article A1 published published ugent 4 Sander Rijckaert Sander Rijckaert aut author 977613653975 0000-0003-4447-0867 Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Ludwig Cardon Ludwig Cardon aut author 802000179080 972410561043 0000-0002-4019-612X TW11 Matthieu Boone Matthieu Boone aut author 802000287093 972712227609 0000-0002-5478-4141 WE05 Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Physics and astronomy WE05 sht department 3E016519 3c0a4b92-b36f-11e9-9b22-19a03077e1f4 2019-10-01 2022-09-30 01XP1717 c007e1ff-1de1-43a1-8ef5-573ce37d58c1 2017-02-01 2024-01-31 01J02013 23e0ac1b-2d66-4695-b51c-6f6965e4da3d 2013-03-01 2017-12-31 BOF/STA/202009/046 25182d45-ccf4-11eb-9f0b-e5cd0f711fbd 2021-07-01 2025-06-30 2073-4360 2022 14 2 298 2022 Technology and Engineering Polymers and Plastics General Chemistry additive manufacturing FFF FDM mechanical testing microscopy low-cost CONTINUOUS CARBON-FIBER MECHANICAL-PROPERTIES PLY THICKNESS SURFACE-TREATMENT ACID COMPOSITES STRENGTH TENSILE GLASS IMPREGNATION PERFORMANCE info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8733959/file/8733961 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 4267916 bytes Full_paper_PETG-aramid_printed_composites.pdf https://biblio.ugent.be/publication/8733959/file/8733962 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf dataset http://purl.org/dc/dcmitype/Dataset 1556926 bytes Supporting_info.pdf Rijckaert, Sander, Lode Daelemans, Ludwig Cardon, Matthieu Boone, Wim Van Paepegem, and Karen De Clerck. 2022. “Continuous Fiber-Reinforced Aramid/PETG 3D-Printed Composites with High Fiber Loading through Fused Filament Fabrication.” POLYMERS 14 (2). doi:10.3390/polym14020298.

These electrochemical processes typically make use of an ion-exchange membrane in between the anode and cathode. The choice of material for this membrane is crucial for the performance of the cell and often its performance is the key bottleneck. Over the last decade, research has been focused on the production of ion-exchange nanofibers as membrane material due to their outstanding ionic properties as a result of their specific morphology. Nanofiber membranes are known to have a large specific surface area, flexibility, high porosity and interconnected pores. Different strategies are applied for the production and structural design of these ion-exchange nanofiber membranes, which are discussed in this review. Nanofibers with an ion-exchange functionality can be produced by either pre-or postfunctionalization methods, combined with electrospinning. Depending on the application, these nanofiber mats can be used as such, or further membrane processing is possible to improve the dimensional stability, typically by adding a pore-filling matrix in between the nanofibers. Eventually, the current state of research on ion-exchange nanofibers in electrochemical separation and degradation applications is discussed. The many examples highlighted in this review prove the potential of nanofibers as ion-exchangers and provide insights for future research in this area. journalArticle review public Review VABB-1 not-approved A1 published published ugent 2 Bianca Swanckaert Bianca Swanckaert aut author 978889457589 0000-0001-6036-6512 Jozefien Geltmeyer Jozefien Geltmeyer aut author 000070582957 975000449525 0000-0002-1281-2968 Korneel Rabaey Korneel Rabaey aut author 801001551956 972717941111 0000-0001-8738-7778 LA25 Klaartje De Buysser Klaartje De Buysser aut author 801001571962 978828372447 0000-0001-7462-2484 WE06 Luiza Bonin Luiza Bonin aut author 802002939944 0000-0001-7123-0012 LA25 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Biotechnology LA25 sht department Department of Chemistry WE06 sht department 3S039119 9cfd7b5f-f96d-11e9-b85e-e128f57a36f9 2019-11-01 2023-10-31 1383-5866 1873-3794 2022 287 120529 2022 Technology and Engineering Chemistry Ion-exchange membranes Nanofibers Electrospinning Electrochemical separation Wastewater treatment WASTE-WATER TREATMENT MICROBIAL FUEL-CELL ADVANCED OXIDATION PROCESSES COMPOSITE MEMBRANES BIOELECTROCHEMICAL SYSTEMS ELECTROLYTE MEMBRANES POLYMER NANOFIBERS BIPOLAR MEMBRANE ELECTROSPUN NANOFIBERS SCALE ELECTRODIALYSIS info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8735807/file/8735833 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 7746733 bytes Swanckaert_et_al_SEPPUR_2022.pdf https://biblio.ugent.be/publication/8735807/file/8743627 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1717486 bytes Accepted_version_Review_paper_ion-exchange_nanofibers.pdf Swanckaert, Bianca, Jozefien Geltmeyer, Korneel Rabaey, Klaartje De Buysser, Luiza Bonin, and Karen De Clerck. 2022. “A Review on Ion-Exchange Nanofiber Membranes : Properties, Structure and Application in Electrochemical (Waste)Water Treatment.” SEPARATION AND PURIFICATION TECHNOLOGY 287. doi:10.1016/j.seppur.2022.120529.

The potential of 2-n-butyl-2-oxazoline (B) and 2-ethyl-2-oxazoline (E) statistical copolymers as a universal, versatile support platform for nanofibrous halochromic sensor design is demonstrated. These polymers are electrospinnable from eco-friendly solvent systems, while wettability, moist adsorption capacity, and water-solubility of the membranes can be easily tuned by changing the B/E monomer ratio, ensuring wide applicability. The halochromic sensing functionality is introduced by incorporating the alizarin yellow R (AYR) chromophore, which is covalently modified with an ethyl ester-group or a short poly(2-n-butyl-2-oxazoline) chain, which is demonstrated to simultaneously prevent dye-leaching and allows tuning of the halochromic pH-sensing window. The colorimetric nanofibrous sensors reversibly respond toward aqueous solutions of different pH, (hydrochloric) acid and alkaline (ammonia) vapors, and several biogenic amines with detection limits as low as 5 ppb. Tunability of sensor responsivity, sensitivity, and pKa via manipulation of dye–polymer interactions, determined by support polymer structure and semi-crystallinity, as well as the chain length of the AYR-modified polymer, are discussed. Preliminary proof-of-principle studies indicate the potential of the developed sensors for sub-ppm biogenic amine vapor detection, which may serve as the basis for future applications in food packaging or breath analysis. journalArticle original public Article A1 published published ugent 1 Ella Schoolaert Ella Schoolaert aut author 000100318410 802002133935 975208259089 0000-0003-4345-8225 UGent Ronald Merckx Ronald Merckx aut author 974260040744 0000-0002-2867-0888 Jana Becelaere Jana Becelaere aut author 977861082888 0000-0001-5024-3308 Serge Rijssegem Serge Rijssegem aut author 000130778228 975985389242 Richard Hoogenboom Richard Hoogenboom aut author 802000620432 975196852903 0000-0001-7398-2058 WE07 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Organic and Macromolecular Chemistry WE07 sht department 3G060518 68c7d40e-8a7e-479e-8231-436053702888 2018-01-01 2021-12-31 3GA01014 bb43e08f-d2c3-4f7d-922e-a8c0a105dfb3 2014-01-01 2020-02-29 3S012019 4b38d931-60d8-11e9-aa53-555acf89d448 2019-01-01 2022-12-31 1616-301X 1616-3028 2022 32 1 2106859 2022 Technology and Engineering alizarin yellow R colorimetric sensors eco-friendly electrospinning poly(2-oxazoline)s statistical copolymers INDUCED PKA SHIFTS PHOTOPHYSICAL PROPERTIES COLOR PK(A) POLY(2-OXAZOLINE)S RED POLYPENTAPEPTIDES SPECTRA PROTEIN PROBES info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8719362/file/8719364 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 4556317 bytes Manuscript_ES.pdf https://biblio.ugent.be/publication/8719362/file/8734683 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 2873730 bytes Publisher_version.pdf Schoolaert, Ella, Ronald Merckx, Jana Becelaere, Serge Rijssegem, Richard Hoogenboom, and Karen De Clerck. 2022. “Eco-Friendly Colorimetric Nanofiber Design : Halochromic Sensors with Tunable PH-Sensing Regime Based on 2-Ethyl-2-Oxazoline and 2-n-Butyl-2-Oxazoline Statistical Copolymers Functionalized with Alizarin Yellow R.” ADVANCED FUNCTIONAL MATERIALS 32 (1). doi:10.1002/adfm.202106859.

To be able to do so, the performance of multiple materials needs to be determined via mechanical testing. Here, we present the ability to combine mechanical tests with microstructural observations, which gives new insight into the microscale deformation and fracture mechanisms present in materials. Thanks to Scanning Electron Microscopy (SEM) during testing, we are able to perform in-situ visualization of the microstructure of the material and how it responds to mechanical loads. SEM offers a high resolution, a wide range of magnification, and a higher field of depth than traditional optical microscopic techniques. With these new insights, materials can be tuned more efficiently towards their specific applications. conference poster public C3 published published ugent Olivier Verschatse Olivier Verschatse aut author 974442908376 0000-0001-7732-6007 Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Ghent, Belgium 2022-10-28 2022-10-28 3E016519 3c0a4b92-b36f-11e9-9b22-19a03077e1f4 2019-10-01 2022-09-30 BOF/STA/202009/046 25182d45-ccf4-11eb-9f0b-e5cd0f711fbd 2021-07-01 2025-06-30 2022 2022 Technology and Engineering info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01GMVB42YZ7M41FSKMW0A8VYYD/file/01GMX60QGTNKBT0MEZ5DQV3EB9 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 3325298 bytes fears_2022_poster.pdf Verschatse, Olivier, Lode Daelemans, Wim Van Paepegem, and Karen De Clerck. 2022. “Observing Deformation Mechanisms at Microscale.” In Faculty of Engineering and Architecture Research Symposium 2022 (FEARS 2022), Abstracts. doi:10.5281/zenodo.7405881.

Solvent electrospinning of a solution of the drug and poly (2-ethyl-2-oxazoline) (PEtOx) is demonstrated to be a viable strategy to produce stable nanofibrous amorphous solid dispersions (ASDs) with ultrahigh drug-loadings (up to 55 wt% Flu) and long-term stability (at least one year). Importantly, at such high drug loadings, the concentration of the polymer in the electrospinning solution has to be lowered below the concentration where it can be spun in absence of the drug as the interactions between the polymer and the drug result in increased solution viscosity. A combination of experimental analysis and molecular dynamics simula- tions revealed that this formulation strategy provides strong, dominant and highly stable hydrogen bonds be- tween the polymer and the drug, which is crucial to obtain the high drug-loadings and to preserve the long-term amorphous character of the ASDs upon storage. In vitro drug release studies confirm the remarkable potential of this electrospinning formulation strategy by significantly increased drug solubility values and dissolution rates (respectively tripled and quadrupled compared to the crystalline drug), even after storing the formulation for one year. journalArticle original public Article A1 published published ugent 1 Jana Becelaere Jana Becelaere aut author 977861082888 0000-0001-5024-3308 Elias Van Den Broeck Elias Van Den Broeck aut author 971635909747 0000-0002-9609-4333 UGent Ella Schoolaert Ella Schoolaert aut author 000100318410 802002133935 975208259089 0000-0003-4345-8225 UGent Valérie Vanhoorne Valérie Vanhoorne aut author 802001047939 977541519725 0000-0003-4249-3408 FW01 Joachim Van Guyse Joachim Van Guyse aut author 000080062786 802001924676 979806612797 Maarten Vergaelen Maarten Vergaelen aut author 000080251635 802001657928 978043257578 UGent Sander Borgmans Sander Borgmans aut author 802002828695 0000-0002-9187-4293 TW17 Karolien Creemers Karolien Creemers aut author 000150641404 919028547508 Veronique Van Speybroeck Veronique Van Speybroeck aut author 801001153549 919016668139 976495757166 0000-0003-2206-178X TW17 WE05 Chris Vervaet Chris Vervaet aut author 801000867397 973325837380 0000-0002-1291-6054 FW01 Richard Hoogenboom Richard Hoogenboom aut author 802000620432 975196852903 0000-0001-7398-2058 WE07 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Applied physics TW17 sht department Department of Organic and Macromolecular Chemistry WE07 sht department Department of Pharmaceutics FW01 sht department Department of Physics and astronomy WE05 sht department 3G060518 68c7d40e-8a7e-479e-8231-436053702888 2018-01-01 2021-12-31 3S013517 4c4bb546-8208-11e9-8dbc-f3943d565b0b 2017-01-01 2021-03-31 3S000718 d89c7f90-be65-11e9-ace9-8bf558aeac68 2018-01-01 2022-12-31 HPC-UGent 01-JAN-08 0168-3659 1873-4995 2022 351 123 136 2022 Technology and Engineering Chemistry Medicine and Health Sciences Amorphous solid dispersions Solvent electrospinning Molecular dynamics Computational chemistry Poly(2-ethyl-2-oxazoline) Flubendazole info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8768650/file/8768653 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 10481930 bytes 1-s2.0-S016836592200623X-main_16_.pdf https://biblio.ugent.be/publication/8768650/file/01GK6ED97DTWYFQEP81XSNQAV9 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 2020682 bytes Accepted_manuscript.pdf https://biblio.ugent.be/publication/8768650/file/01GK6EEF3B9YDKM1JC39E2N4MB info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf dataset http://purl.org/dc/dcmitype/Dataset 2686521 bytes Supporting_information.pdf Becelaere, Jana, Elias Van Den Broeck, Ella Schoolaert, Valérie Vanhoorne, Joachim Van Guyse, Maarten Vergaelen, Sander Borgmans, Karolien Creemers, Veronique Van Speybroeck, Chris Vervaet, Richard Hoogenboom, and Karen De Clerck. 2022. “Stable Amorphous Solid Dispersion of Flubendazole with High Loading via Electrospinning.” JOURNAL OF CONTROLLED RELEASE 351: 123–136. doi:10.1016/j.jconrel.2022.09.028.

However, the production via a combination of sol-gel synthesis and electrospinning depends on many factors of which the influence is not completely understood. In this work, we investigate the link between the viscosity and the electrospinnability of the tetraethylorthosilicate (TEOS) based spinning solution as a first step in linking the different scales in the process. The viscosity of the silica sol has a clear effect on the behavior of the Taylor cone and hence on the stability of the electrospinning process. Exploiting these insights is of great importance for future chemically driven tuning of silica nanofibrous membranes. conference poster public C3 published published ugent Sofie Verschraegen Sofie Verschraegen aut author 000150868746 802003501534 919029486586 975200255882 0000-0002-6164-3662 TW11 Klaartje De Buysser Klaartje De Buysser aut author 801001571962 978828372447 0000-0001-7462-2484 WE06 Dagmar D'hooge Dagmar D'hooge aut author 802000024082 973689492909 0000-0001-9663-9893 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Chemistry WE06 sht department Ghent, Belgium 2022-10-28 2022-10-28 3F006621 190fbf11-2a82-11ec-95aa-05ef7abe0c3c 2021-11-01 2025-10-31 2022 2022 Technology and Engineering info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/01GMVB2854B8827YKTB6VNSYM7/file/01GMXMEBX4JSJDC9QT9G9VJ6DK info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 755723 bytes fears_2022_poster.pdf Verschraegen, Sofie, Klaartje De Buysser, Dagmar D’hooge, and Karen De Clerck. 2022. “Electrospinning of Silica Nanofibers : How the Sol Viscosity Influences the Taylor Cone.” In Faculty of Engineering and Architecture Research Symposium 2022 (FEARS 2022), Abstracts. doi:10.5281/zenodo.7400772.

Enhanced endothelial cell interactivity is of particular interest when targeting cardiovascular applications, more specifically, for creating synthetic vascular bypass grafts. In this study, the potential of PAT((n=10)) to be applied as synthetic bypass graft has been further investigated. After a thorough physico-chemical characterization of the synthesized PAT((n=10)), microsized fibers were processed via electrospinning. In a first part, the polymer-related parameters were investigated and optimized to obtain uniform beadless fibers. By changing the solution composition and device set-up, various fiber morphologies (i.e. random, aligned and porous fibers) were obtained and subjected to an in vitro biological evaluation with Human Umbilical Vein Endothelial Cells (HUVECs), while exploiting a clinically used synthetic graft (i.e. Dacron (R)) as benchmark. It was shown that the cells seeded onto all PAT((n=10)) fibers exhibited a superior metabolic activity compared to Dacron after 7 days of culture, while aligned and porous fibers had a beneficial effect on the survival of HUVECs. This study is a first step towards the application of PATs as novel cardiovascular bypass graft, fabricated via electrospinning. journalArticle original public Article A1 published published ugent 2 Babs Van de Voorde Babs Van de Voorde aut author 973915189273 Berna Şensu Berna Şensu aut author 000190304094 971758523609 Lobke De Vos Lobke De Vos aut author 000150666864 802003513355 979331383630 WE07 FW02 Robin Colenbier Robin Colenbier aut author 000120713971 802002726544 973942971992 Havva Başkan Havva Başkan aut author 000181437082 978594688030 Jozefien Geltmeyer Jozefien Geltmeyer aut author 000070582957 975000449525 0000-0002-1281-2968 Laurens Parmentier Laurens Parmentier aut author 802003290659 974167330669 0000-0002-5849-3042 WE07 Lenny Van Daele Lenny Van Daele aut author 802002999962 977727816511 0000-0002-6335-395X WE07 LA25 Ruslan Dmitriev Ruslan Dmitriev aut author 802003468996 978749151739 0000-0002-0347-8718 GE38 Lincy Pyl Lincy Pyl aut author Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Sandra Van Vlierberghe Sandra Van Vlierberghe aut author 801001801429 971159275288 0000-0001-7688-1682 WE07 Department of Organic and Macromolecular Chemistry WE07 sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Human Structure and Repair GE38 sht department 179I01217 f16f23c2-b9f8-41ae-896e-e004c8a0c50a 2018-01-01 2021-12-31 41W08919 231a3a5c-4c12-42d6-af0d-3716b6e1fd8e 2019-04-01 2022-03-31 3S003621 4b0688fa-2a81-11ec-a6b4-cd4eac00b947 2021-11-01 2025-11-23 3S013220 d3e42973-0fb3-11eb-89fc-81e15036b2fa 2020-11-01 2024-10-31 3S041519 5794adb9-f98c-11e9-9191-7fc8fa7ad5b7 2019-11-01 2023-10-31 0014-3057 1873-1945 2022 165 111003 2022 Chemistry Organic Chemistry Polymers and Plastics General Physics and Astronomy Materials Chemistry Poly(decamethylene terephthalate) Electrospinning Human Umbilical Vein Endothelial Cells Live dead staining MOLECULAR-WEIGHT POLYMER NANOFIBERS SCAFFOLDS BIOCOMPATIBILITY DEGRADATION BEHAVIOR DENSITY info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8735806/file/8747297 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 5675126 bytes 2022_Electrospinning_PAT_Babs-SVV.pdf https://biblio.ugent.be/publication/8735806/file/01KATN43KS0WJXY42SH7D54F3R info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/vnd.openxmlformats-officedocument.wordprocessingml.document fullText http://purl.org/dc/dcmitype/Text 2786604 bytes Electrospinning of poly(decamethylene terephthalate) to support vascular graft applications.docx Van de Voorde, Babs, Berna Şensu, Lobke De Vos, Robin Colenbier, Havva Başkan, Jozefien Geltmeyer, Laurens Parmentier, Lenny Van Daele, Ruslan Dmitriev, Lincy Pyl, Karen De Clerck, and Sandra Van Vlierberghe. 2022. “Electrospinning of Poly(Decamethylene Terephthalate) to Support Vascular Graft Applications.” EUROPEAN POLYMER JOURNAL 165. doi:10.1016/j.eurpolymj.2022.111003.

The three-dimensional arrangement of natural and synthetic network materials determines their application range. Control over the real-time incorporation of each building block and functional group is desired to regulate the macroscopic properties of the material from the molecular level onwards. Here we report an approach combining kinetic Monte Carlo and molecular dynamics simulations that chemically and physically predicts the interactions between building blocks in time and in space for the entire formation process of three-dimensional networks. This framework takes into account variations in inter- and intramolecular chemical reactivity, diffusivity, segmental compositions, branch/network point locations and defects. From the kinetic and three-dimensional structural information gathered, we construct structure-property relationships based on molecular descriptors such as pore size or dangling chain distribution and differentiate ideal from non-ideal structural elements. We validate such relationships by synthesizing organosilica, epoxy-amine and Diels-Alder networks with tailored properties and functions, further demonstrating the broad applicability of the platform. journalArticle original public Article A1 published published ugent 1 Lies De Keer Lies De Keer aut author 000100481791 802002106754 971930032541 0000-0003-2620-0046 Karsu I.

These are not currently recycled due to the presence of harmful finishes on the waste fabrics, that interfere with the recycling process, reduce the quality of the recycled product, and pose health risks. Through a combination of confidential washing, hydrolysis and physical treatments, all the finishing chemicals on waste, outdoor acrylic fabrics can be removed by at least 90%, thus enabling the mechanical recycling process. conference meetingAbstract public C3 published published ugent Brecht Tomme Brecht Tomme aut author 000120101558 802003221547 975685845663 0000-0001-7765-3059 TW11 Valentina Trovato Valentina Trovato aut author Jozefien Geltmeyer Jozefien Geltmeyer aut author 000070582957 975000449525 0000-0002-1281-2968 Giuseppe Rosace Giuseppe Rosace aut author Daniele Piga Daniele Piga aut author Barbara Ferrari Barbara Ferrari aut author Andrea Cataldi Andrea Cataldi aut author Steven De Meester Steven De Meester aut author 802000481497 973680737243 0000-0002-5246-3918 LA24 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Fernando Ferreira Fernando Ferreira edt editor A.

The large chemical diversity amongst these molecules leads to compound-specific properties such as color and stability towards external conditions. These properties are also attractive for food and non-food applications. The photophysical experimental characterization is not easy as this generally demands advanced analytical techniques along with optimized separation procedures. Molecular modeling can provide insights into the fundamental understanding of the photophysical properties of these compounds in a uniform way for a broad set of compounds. However, the current literature is quite fragmented on this topic. Herein, a large set of 140 naturally derived anthocyanins was evaluated in a systematic way with three functionals (B3LYP, PBE0, and CAM-B3LYP). The accuracy of these functionals was determined with experimental literature lambda(max,vis) values. In addition to lambda(max,vis) values, time-dependent (TD)-DFT calculations also provided oscillator strengths, molar absorption coefficients, and orbital energies, which define whether specific natural anthocyanin-based compounds can be deployed in food and non-food applications such as food additives/colorants, textile dyeing, analytical standards, and dye-sensitized solar cells (DSSCs). journalArticle original public Article VABB-1 not-approved A1 published published ugent 8 Kim Phan Kim Phan aut author 000090124821 802002578620 971260175395 0000-0001-8660-5251 UGent Steven De Meester Steven De Meester aut author 802000481497 973680737243 0000-0002-5246-3918 LA24 Katleen Raes Katleen Raes aut author 801001275508 973092298160 0000-0003-2382-120X LA23 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Veronique Van Speybroeck Veronique Van Speybroeck aut author 801001153549 919016668139 976495757166 0000-0003-2206-178X TW17 WE05 Department of Green Chemistry and Technology LA24 sht department Department of Food technology, Safety and Health LA23 sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Physics and astronomy WE05 sht department 0947-6539 1521-3765 2021 27 19 5956 5971 2021 Chemistry General Chemistry anthocyanins pyranoanthocyanins time-dependent density functional theory UV Vis spectroscopy info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/8693084/file/8703423 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 3682210 bytes published.pdf Phan, Kim, Steven De Meester, Katleen Raes, Karen De Clerck, and Veronique Van Speybroeck. 2021. “A Comparative Study on the Photophysical Properties of Anthocyanins and Pyranoanthocyanins.” CHEMISTRY-A EUROPEAN JOURNAL 27 (19): 5956–5971. doi:10.1002/chem.202004639.

In this approach, data is obtained at different temperatures, usually through a stepped isothermal method (SIM) on the same sample. Dynamic mechanical analysis (DMA) instruments offer two different measurement methods to obtain SIM data: (i) static creep tests and (ii) dynamic frequency sweeps. This paper compares both methods on highly graphite filled polypropylene. Our studies on reproducibility of each method show that the uncertainty for 20 year prediction can be lower than 6% for both methods. While creep-based tests require a shorter experimental time, frequency sweep based tests show a lower scatter on the final result. The two main factors introducing uncertainty on the end results are related to (i) the reproducibility of the experimental raw data and (ii) the TTS optimisation using shift factors. The optimisation of the shift factors by a numerical method improves the accuracy of the master curve. By comparing creep and frequency sweep SIM, it shows that for predictions of one decade, the methods deliver very comparable results (less than 10% difference). For longer predictions, the methods differ and are not interchangeable. Furthermore, DMA was also effectively used as a three-point bending setup, providing information about strain rate sensitivity and the linear visco-elastic region using the same test setup and same sample dimensions as for TTS. journalArticle original public Article A1 published published ugent 1 Joanna Schalnat Joanna Schalnat aut author 976703632210 Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Ives De Baere Ives De Baere aut author 801001866905 977854465771 0000-0002-6846-0981 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department 3E016519 3c0a4b92-b36f-11e9-9b22-19a03077e1f4 2019-10-01 2022-09-30 0142-9418 1873-2348 2021 103 107368 2021 Technology and Engineering Polymers and Plastics Organic Chemistry Time temperature superposition principle (TTS) Stepped isothermal method (SIM) Dynamic (thermo-) mechanical analysis (DMA DTMA) Graphite filled polymer Life time predictions info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8723036/file/8723037 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 5916527 bytes Schalnat2021Frequency.pdf Schalnat, Joanna, Lode Daelemans, Ives De Baere, Karen De Clerck, and Wim Van Paepegem. 2021. “Long-Term Stiffness Prediction of Particle Filled Polymers by Dynamic Mechanical Analysis : Frequency Sweep versus Creep Method.” POLYMER TESTING 103. doi:10.1016/j.polymertesting.2021.107368.

Yet, its brittle fracture behavior is an important downside for many sectors. Here, we show that the addition of electrospun thermoplastic nanofibers is a viable toughening strategy to design nanofiber reinforced epoxy materials with excellent toughness. Moreover, the use of transparent film-like specimens allowed in-situ imaging during mechanical testing. Optical and scanning electron microscopy, digital image correlation and crack length measurements are used to analyze the toughening mechanisms responsible for high toughening efficiency in detail. The addition of polyamide and polycaprolactone nanofibers resulted in an increased plastic energy uptake up to 100%. In-situ observation of the crack tip showed that the main energy-absorbing mechanism was due to bridging nanofibers. There was a profound decrease in toughening efficiency when nanofibers lacked sufficient adhesion with the matrix only when they were oriented parallel with the crack growth direction. The profound understanding of such underlying mechanisms opens up material design in applications where high toughness is required like adhesives, coatings, and fiber-reinforced composite laminates. journalArticle original public Article A1 published published ugent 3 Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Olivier Verschatse Olivier Verschatse aut author 974442908376 0000-0001-7732-6007 Lisa Heirman Lisa Heirman aut author Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department 3E016519 3c0a4b92-b36f-11e9-9b22-19a03077e1f4 2019-10-01 2022-09-30 01P03418 b2c0136d-5a95-11e9-b3e1-37a68b033e1d 2019-01-01 2019-09-30 0266-3538 1879-1050 2021 201 108504 2021 Technology and Engineering General Engineering Ceramics and Composites Nano composites Coating Fracture toughness Interfacial strength Damage mechanics Digital image correlation info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8678232/file/8678235 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 16410733 bytes Toughening_mechanisms_in_nanofibre_epoxy_2021_-_journal_version.pdf https://biblio.ugent.be/publication/8678232/file/8678236 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 3506202 bytes Toughening_mechanisms_in_nanofibre_epoxy_2021_-_postprint.pdf https://biblio.ugent.be/publication/8678232/file/8678237 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/video/mp4 dataset http://purl.org/dc/dcmitype/Dataset 43924441 bytes Video_1_SENT_specimen.mp4 Daelemans, Lode, Olivier Verschatse, Lisa Heirman, Wim Van Paepegem, and Karen De Clerck. 2021. “Toughening Mechanisms Responsible for Excellent Crack Resistance in Thermoplastic Nanofiber Reinforced Epoxies through In-Situ Optical and Scanning Electron Microscopy.” COMPOSITES SCIENCE AND TECHNOLOGY 201. doi:10.1016/j.compscitech.2020.108504.

Currently, the state-of-the-art dielectric sensors mainly focus on detecting the distinct stages of the polymeric composite curing process. While low-cost and quantitative monitoring of the thermal, mechanical, and chemical properties of the materials during the cure is of great interest, to date, such a sensor system has not been realized because the existing devices excessively depend on external instrumentations, combined with a lack of an embedded reliable data processing module. Here, a fully integrated dielectric monitoring sensor system (DMS) incorporating dielectric and temperature sensors is developed, capable of monitoring in real-time the temperature, the degree of cure, and the glass transition temperature (T-g) of polymeric composites. An independent characterization of the cure kinetics was performed using differential scanning calorimetry and Raman spectroscopy. These data enabled associating the main physical and chemical transformations in the polymeric materials with particular features observed in the dielectric measurements. We demonstrate the accurate estimation of the degree of cure and T-g of an epoxy resin. The proposed system shows the potential for a new generation of intelligent manufacturing technology of composite materials. journalArticle original public Article A1 published published ugent 3 Yang Yang Yang Yang aut author Bart Plovie Bart Plovie aut author 000120984662 802001686523 978920143743 0000-0002-3337-5955 UGent Gabriele Chiesura Gabriele Chiesura aut author 000100191502 802001344797 977870335476 UGent Thomas Vervust Thomas Vervust aut author 802000228388 978214065989 0000-0003-2771-3679 TW06 Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Diana-Elena Mogosanu Diana-Elena Mogosanu aut author 000110887669 802001116950 977380651487 UGent Pieter Wuytens Pieter Wuytens aut author 000110911113 802001259319 976589178775 UGent Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Jan Vanfleteren Jan Vanfleteren aut author 801000674512 979431558156 0000-0002-9654-7304 TW06 Department of Electronics and information systems TW06 sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department Imec IMEC sht department 3E016519 3c0a4b92-b36f-11e9-9b22-19a03077e1f4 2019-10-01 2022-09-30 0018-9456 1557-9662 2021 70 6004809 2021 Technology and Engineering Cure monitoring dielectric sensor degree of cure fully integrated system glass transition temperature info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/8707503/file/8707504 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 3600126 bytes 09359661.pdf Yang, Yang, Bart Plovie, Gabriele Chiesura, Thomas Vervust, Lode Daelemans, Diana-Elena Mogosanu, Pieter Wuytens, Karen De Clerck, and Jan Vanfleteren. 2021. “Fully Integrated Flexible Dielectric Monitoring Sensor System for Real-Time in Situ Prediction of the Degree of Cure and Glass Transition Temperature of an Epoxy Resin.” IEEE TRANSACTIONS ON INSTRUMENTATION AND MEASUREMENT 70. doi:10.1109/TIM.2021.3057291.

Here we focus on FFF composite formation using ductile poly (butylene adipate-co-terephthalate) (PBAT), the nanoclay cloisite and the chain extender Joncryl. A high modulus, flexibility, toughness and notched impact strength result upon combining PLA/PBAT (80:20; mass basis) with a sufficiently high cloisite amount (1-5 phr) supported by a suited Joncryl amount (0.3 phr). A fine PBAT dispersion is then ensured, as confirmed by scanning and transmission electron microscopy. For high cloisite amounts (e.g. 10 phr) the crystallinity and vicat softening temperature enhance but cloisite aggregation is unavoidable, leading to a strong reduction in tensile strain and toughness. Annealing increases crystallinity thus material strength, rigidity and impact, at least partially overruling the need of a fine dispersion. Novel radar charts are also reported to select an optimal bio-based blend suitable for different end-user applications by adjusting the composition and possible post-annealing of printed products. journalArticle original public Article A1 published published ugent 1 Sisi Wang Sisi Wang aut author 000160916128 802002436857 979929499370 Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Dagmar D'hooge Dagmar D'hooge aut author 802000024082 973689492909 0000-0001-9663-9893 TW11 Liesbeth Couck Liesbeth Couck aut author 802001945591 915273238883 978851740858 0000-0002-7965-4992 DI11 Wim Van Den Broeck Wim Van Den Broeck aut author 801000970865 975971404771 0000-0001-6683-5658 DI11 Pieter Cornillie Pieter Cornillie aut author 801001653202 971128432019 0000-0003-4412-3427 DI11 Maling Gou Maling Gou aut author Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Ludwig Cardon Ludwig Cardon aut author 802000179080 972410561043 0000-0002-4019-612X TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Morphology (ceased 1-1-2022) DI03 sht department 3E016519 3c0a4b92-b36f-11e9-9b22-19a03077e1f4 2019-10-01 2022-09-30 1359-8368 1879-1069 2021 210 108613 2021 Technology and Engineering Mechanical Engineering Industrial and Manufacturing Engineering Mechanics of Materials Ceramics and Composites Biopolymers Additive manufacturing Composites Thermo-mechanical properties info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/8694251/file/8694252 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 9528977 bytes 7.DHOOGE-Lifting_the_quality_of_fused_filament_fabrication_of_polylactic_acid_based_composites.pdf Wang, Sisi, Lode Daelemans, Dagmar D’hooge, Liesbeth Couck, Wim Van Den Broeck, Pieter Cornillie, Maling Gou, Karen De Clerck, and Ludwig Cardon. 2021. “Lifting the Quality of Fused Filament Fabrication of Polylactic Acid Based Composites.” COMPOSITES PART B-ENGINEERING 210. doi:10.1016/j.compositesb.2021.108613.

In these products, bioresorption and biocompatibility play a key role. The aim of this study is to provide progress in this area via nanofabrication and antimicrobial natural materials. Polyhydroxyalkanoates (PHAs) are a bio-based family of polymers that possess high biocompatibility and skin regenerative properties. In this study, a blend of poly(3-hydroxybutyrate) (P(3HB)) and poly(3-hydroxyoctanoate-co-3-hydroxy decanoate) (P(3HO-co-3HD)) was electrospun into P(3HB))/P(3HO-co-3HD) nanofibers to obtain materials with a high surface area and good handling performance. The nanofibers were then modified with silver nanoparticles (AgNPs) via the dip-coating method. The silver-containing nanofiber meshes showed good cytocompatibility and interesting immunomodulatory properties in vitro, together with the capability of stimulating the human beta defensin 2 and cytokeratin expression in human keratinocytes (HaCaT cells), which makes them promising materials for wound dressing applications. journalArticle original public Article A1 published published ugent 5 Özlem İpek Kalaoglu Altan Özlem İpek Kalaoglu Altan aut author 000091814136 802003037550 975697430594 UGent Havva Başkan Havva Başkan aut author 000181437082 978594688030 Timo Meireman Timo Meireman aut author 972580996713 Pooja Basnett Pooja Basnett aut author Bahareh Azimi Bahareh Azimi aut author Alessandra Fusco Alessandra Fusco aut author Niccola Funel Niccola Funel aut author Giovanna Donnarumma Giovanna Donnarumma aut author Andrea Lazzeri Andrea Lazzeri aut author Ipsita Roy Ipsita Roy aut author Serena Danti Serena Danti aut author Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department 41A09117 035f6009-5e69-457b-8ff6-598f0e66069f 2017-06-01 2020-07-31 1996-1944 2021 14 17 4907 2021 Technology and Engineering General Materials Science polyhydroxyalkanoates eco-friendly nanofibers wound dressings low-impact biomedical applications immunomodulation defensin keratinocytes info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8719114/file/8719142 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 5748258 bytes Silver_Nanoparticle-Coated_Polyhydroxyalkanoate_Based_Electrospun_Fibers_for_Wound_Dressing_Applications.pdf Kalaoglu Altan, Özlem İpek, Havva Başkan, Timo Meireman, Pooja Basnett, Bahareh Azimi, Alessandra Fusco, Niccola Funel, Giovanna Donnarumma, Andrea Lazzeri, Ipsita Roy, Serena Danti, and Karen De Clerck. 2021. “Silver Nanoparticle-Coated Polyhydroxyalkanoate Based Electrospun Fibers for Wound Dressing Applications.” MATERIALS 14 (17). doi:10.3390/ma14174907.

We prepared an olive leaf extract (OLE) and characterized it via high performance liquid chromatography (HPLC) analysis. OLE was blended with different polyhydroxyalkanoates (PHAs), namely, poly(hydroxybutyrate-co-hydroxyvalerate) (PHBHV) and polyhydroxybutyrate/poly(hydroxyoctanoate-co-hydroxydecanoate) (PHB/PHOHD), to produce fiber meshes via electrospinning: OLE/PHBV and OLE/ (PHB/PHOHD), respectively. An 80–90% (w/w%) release of the main polyphenols from the OLE/PHA fibers occurred in 24 h, with a burst release in the first 30 min. OLE and the produced fiber meshes were assayed using human dermal keratinocytes (HaCaT cells) to evaluate the expression of a panel of cytokines involved in the inflammatory process and innate immune response, such as the antimicrobial peptide human beta defensin 2 (HBD-2). Fibers containing OLE were able to decrease the expression of the pro-inflammatory cytokines at 6 h up to 24 h. All the PHA fibers allowed an early downregulation of the pro-inflammatory cytokines in 6 h, which is suggestive of a strong anti-inflammatory activity exerted by PHA fibers. Differently from pure OLE, PHB/PHOHD fibers (both with and without OLE) upregulated the expression of HBD-2. Our results showed that PHA fiber meshes are suitable in decreasing pro-inflammatory cytokines and the incorporation of OLE may enable indirect antibacterial properties, which is essential in wound healing and tissue regeneration. journalArticle original public Article A1 published published ugent 9 Jose Gustavo De la Ossa Jose Gustavo De la Ossa aut author Alessandra Fusco Alessandra Fusco aut author Bahareh Azimi Bahareh Azimi aut author Jasmine Esposito Salsano Jasmine Esposito Salsano aut author Maria Digiacomo Maria Digiacomo aut author Maria-Beatrice Coltelli Maria-Beatrice Coltelli aut author Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Ipsita Roy Ipsita Roy aut author Marco Macchia Marco Macchia aut author Andrea Lazzeri Andrea Lazzeri aut author Giovanna Donnarumma Giovanna Donnarumma aut author Serena Danti Serena Danti aut author Rossella Di Stefano Rossella Di Stefano aut author Department of Materials, Textiles and Chemical Engineering TW11 sht department 41A09117 035f6009-5e69-457b-8ff6-598f0e66069f 2017-06-01 2020-07-31 2076-3417 2021 11 9 4006 2021 Technology and Engineering polyphenol anti-inflammatory antibacterial wound healing wound dressings tissue regeneration bio-based info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8719144/file/8719146 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 4207568 bytes Immunomodulatory_Activity_of_Electrospun_Polyhydroxyalkanoate_Fiber_Scaffolds_Incorporating_Olive_Leaf_Extract.pdf De la Ossa, Jose Gustavo, Alessandra Fusco, Bahareh Azimi, Jasmine Esposito Salsano, Maria Digiacomo, Maria-Beatrice Coltelli, Karen De Clerck, Ipsita Roy, Marco Macchia, Andrea Lazzeri, Giovanna Donnarumma, Serena Danti, and Rossella Di Stefano. 2021. “Immunomodulatory Activity of Electrospun Polyhydroxyalkanoate Fiber Scaffolds Incorporating Olive Leaf Extract.” APPLIED SCIENCES-BASEL 11 (9). doi:10.3390/app11094006.

Therefore, typically metallic mordants are applied to improve the natural dye's affinity towards substrates, but this is not a suitable technique in a 'green story'. In this paper, we test the potential of using anthocyanins from blueberry waste for dyeing cotton with biomordants, which are selected to tailor the intermolecular interactions such as hydrogen bonds, ionic bonds and pi-pi interactions with the dye molecule. In the experimental part, parameters during extraction and dyeing were optimized (e.g. temperature, pH, dyeing time and concentration). The effect of the (bio)mordants was monitored by Fourier transform infrared spectroscopy, spectrophotometric measurements and standard ISO wash and light tests. It was shown that stannous chloride stands out as metallic mordant, while no biomordants show sufficient intermolecular interactions to replace this metal salt. The experimental study has been corroborated with a series of molecular modeling calculations to obtain more insight into the intermolecular interactions between dye and (bio)mordants. To this end, both static Density Functional Theory based calculations as semi-empirical and force field based molecular dynamics calculations have been performed. The results indeed confirm that, in general, too small interaction energies for the biomordants of interest with the dye molecules are found, in correspondence with experimental findings. Overall, by performing systematic experiments in combination with the interpretation of the molecular models, this study yields valuable insights into the development of green routes towards use of anthocyanins as a natural dye for cellulose-based materials. journalArticle original public Article VABB-1 not-approved A1 published published ugent 2 Kim Phan Kim Phan aut author 000090124821 802002578620 971260175395 0000-0001-8660-5251 UGent Elias Van Den Broeck Elias Van Den Broeck aut author 971635909747 0000-0002-9609-4333 UGent Veronique Van Speybroeck Veronique Van Speybroeck aut author 801001153549 919016668139 976495757166 0000-0003-2206-178X TW17 WE05 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Katleen Raes Katleen Raes aut author 801001275508 973092298160 0000-0003-2382-120X LA23 Steven De Meester Steven De Meester aut author 802000481497 973680737243 0000-0002-5246-3918 LA24 Department of Green Chemistry and Technology LA24 sht department Department of Applied physics TW17 sht department Department of Physics and astronomy WE05 sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Food technology, Safety and Health LA23 sht department 0143-7208 1873-3743 2020 176 108180 2020 Chemistry Technology and Engineering Anthocyanins Cotton Density functional theory (DFT) Molecular dynamics Natural dye ANTIOXIDANT ACTIVITY THERMAL-DEGRADATION RED-WINE ADSORPTION WATER COPIGMENTATION COLOR EXTRACTION STABILITY DYNAMICS info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/8644170/file/8644171 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 4963718 bytes PhanThe_potential_of_anthocyanins_from_blueberries_as_a_natural_dye_for_cotton_A_combined_experimental_and_theoretical_study.pdf Phan, Kim, Elias Van Den Broeck, Veronique Van Speybroeck, Karen De Clerck, Katleen Raes, and Steven De Meester. 2020. “The Potential of Anthocyanins from Blueberries as a Natural Dye for Cotton : A Combined Experimental and Theoretical Study.” DYES AND PIGMENTS 176. doi:10.1016/j.dyepig.2019.108180.

Chitin and lignin, byproducts of fishery and plant biomass, show antimicrobial and anti-inflammatory activity on the nanoscale. Due to their polarities, chitin nanofibril (CN) and nanolignin (NL) can be assembled into micro-complexes, which can be loaded with bioactive factors, such as the glycyrrhetinic acid (GA) and CN-NL/GA (CLA) complexes, and can be used to decorate polymer surfaces. This study aims to develop completely bio-based and bioactive meshes intended for wound healing. Poly(3-hydroxybutyrate)/Poly(3-hydroxyoctanoate-co-3-hydroxydecanoate), P(3HB)/P(3HO-co-3HD) was used to produce films and fiber meshes, to be surface-modified via electrospraying of CN or CLA to reach a uniform distribution. P(3HB)/P(3HO-co-3HD) fibers with desirable size and morphology were successfully prepared and functionalized with CN and CLA using electrospinning and tested in vitro with human keratinocytes. The presence of CN and CLA improved the indirect antimicrobial and anti-inflammatory activity of the electrospun fiber meshes by downregulating the expression of the most important pro-inflammatory cytokines and upregulating human defensin 2 expression. This natural and eco-sustainable mesh is promising in wound healing applications. journalArticle original public Article A1 published published ugent Bahareh Azimi Bahareh Azimi aut author Lily Thomas Lily Thomas aut author Alessandra Fusco Alessandra Fusco aut author Özlem İpek Kalaoglu Altan Özlem İpek Kalaoglu Altan aut author 000091814136 802003037550 975697430594 UGent Pooja Basnett Pooja Basnett aut author Patrizia Cinelli Patrizia Cinelli aut author Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Ipsita Roy Ipsita Roy aut author Giovanna Donnarumma Giovanna Donnarumma aut author Maria-Beatrice Coltelli Maria-Beatrice Coltelli aut author Serena Danti Serena Danti aut author Andrea Lazzeri Andrea Lazzeri aut author Department of Materials, Textiles and Chemical Engineering TW11 sht department 41A09117 035f6009-5e69-457b-8ff6-598f0e66069f 2017-06-01 2020-07-31 2079-4983 2020 11 3 62 2020 Technology and Engineering biopolymer bio-based surface modification nanolignin electrospinning electrospray anti-inflammatory DRUG-DELIVERY SCAFFOLDS CHALLENGES info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8675587/file/8675594 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 12146486 bytes jfb-11-00062.pdf Azimi, Bahareh, Lily Thomas, Alessandra Fusco, Özlem İpek Kalaoglu Altan, Pooja Basnett, Patrizia Cinelli, Karen De Clerck, Ipsita Roy, Giovanna Donnarumma, Maria-Beatrice Coltelli, Serena Danti, and Andrea Lazzeri. 2020. “Electrosprayed Chitin Nanofibril/Electrospun Polyhydroxyalkanoate Fiber Mesh as Functional Nonwoven for Skin Application.” JOURNAL OF FUNCTIONAL BIOMATERIALS 11 (3). doi:10.3390/jfb11030062.

By combining liquid chromatography-mass spectrometry and kinetic Monte Carlo modeling, we demonstrate that upon optimizing the dip-coating conditions (0.34 mol L (-1) TiO2 solution at a coating speed of 160 mm min( -1)) for the functionalization of a superhydrophilic electrospun silica nanofibrous membrane (i) hydroxylation is a dominant reaction pathway and (ii) once IPU reacts on the surface of the TiO(2 )nanoparticles, further hydroxylation occurs sufficiently fast, with complete IPU removal under the detection limit (5-10 mg Lsolution(-1)) as a result of UV irradiation within 8 h. As hydroxylation is dominant, degradation intermediates with a higher water solubility are formed and therefore a decreased toxicity is obtained upon reintroducing the treated solution into the environment. This is confirmed by respirometry, with an increase in the oxygen uptake rate of an activated sludge from 5.9 mg O(2 )g(activated) ( -1)(sludge) h (-1 )for an untreated 10 mg L-1 IPU solution to 8.2 mg O-2 g(activated sludge) (-1) h( -1) for a solution irradiated for 8 h, in line with a blank solution. journalArticle original public Article A1 published published ugent 1 Eva Loccufier Eva Loccufier aut author 802002671374 974161061035 0000-0001-7045-2721 TW11 Koen Deventer Koen Deventer aut author 801001589039 976190968315 0000-0001-8038-1824 GE32 Dave Manhaeghe Dave Manhaeghe aut author 802002394623 976978290033 0000-0002-4117-6892 LA24 Stijn Van Hulle Stijn Van Hulle aut author 801001539933 919019834884 971483871644 0000-0001-5773-7773 LA24 Dagmar D'hooge Dagmar D'hooge aut author 802000024082 973689492909 0000-0001-9663-9893 TW11 Klaartje De Buysser Klaartje De Buysser aut author 801001571962 978828372447 0000-0001-7462-2484 WE06 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Chemistry WE06 sht department Department of Green Chemistry and Technology LA24 sht department Department of Diagnostic Sciences GE32 sht department 1385-8947 1873-3212 2020 387 124143 2020 Technology and Engineering Chemistry Photodegradation kinetics Water treatment Electrospinning Kinetic Monte Carlo modeling Respirometry Hydroxylation ADVANCED OXIDATION PROCESSES HETEROGENEOUS PHOTOCATALYTIC DEGRADATION WASTE-WATER TREATMENT HERBICIDE ISOPROTURON ELECTROSPUN NANOFIBERS INTERMEDIATE PRODUCTS LIQUID-CHROMATOGRAPHY AQUEOUS-SOLUTION SUPPORTED TIO2 AZO DYES info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8644208/file/8644213 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 2829986 bytes Degradation_kinetics_of_isoproturon_and_its_subsequent_products_in_contact_with_TiO2_functionalized_silica_nanofibers.pdf https://biblio.ugent.be/publication/8644208/file/8649160 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/vnd.openxmlformats-officedocument.wordprocessingml.document dataset http://purl.org/dc/dcmitype/Dataset 5492163 bytes Supporting_Information.docx https://biblio.ugent.be/publication/8644208/file/8649161 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 442856 bytes Manuscript.pdf Loccufier, Eva, Koen Deventer, Dave Manhaeghe, Stijn Van Hulle, Dagmar D’hooge, Klaartje De Buysser, and Karen De Clerck. 2020. “Degradation Kinetics of Isoproturon and Its Subsequent Products in Contact with TiO2 Functionalized Silica Nanofibers.” CHEMICAL ENGINEERING JOURNAL 387. doi:10.1016/j.cej.2020.124143.

In the past decade, we have seen a steady increase in published research papers and industrial interest on this topic. In this chapter, we highlight the major findings related to the use of electrospun nanofiber toughening veils together with a concise overview of our own research trajectory of the past years on this topic. There are five main sections in this chapter which guide the reader (be them experienced or inexperienced with the topic) through the current state-of-the-art: an introductory section (Section 11.1), a section about the mechanisms of nanofiber toughening (Section 11.2), an overview of the nanofiber effect on a broad range of mechanical properties (Section 11.3), important considerations regarding nanofiber toughening (Section 11.4), and a future outlook and concluding section (Sections 11.5 and 11.6). bookChapter public B2 published published ugent Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Baogue Han Baogue Han edt editor Tuan Anh Nguyen Tuan Anh Nguyen edt editor K.

At a high volume fraction of reinforcing fibers, the matrix is confined to a microscale region in between the fibers (1–200 µm). Although these regions are interconnected, their behavior is likely dominated by their micro-scale. Nevertheless, the characterization of the matrix material (without reinforcing fibers) is usually performed on macroscopic bulk specimens and little is known about the micro-mechanical behavior of polymer matrix materials. Here, we show that the microscale behavior of an epoxy resin typically used in composite production is clearly different from its macroscale behavior. Microscale polymer specimens were produced by drawing microfibers from vitrifying epoxy resin. After curing, tensile tests were performed on a large set of pure epoxy microfiber specimens with diameters ranging from 30 to 400 µm. An extreme ductility was observed for microscale epoxy specimens, while bulk scale epoxy specimens showed brittle behavior. The microsized epoxy specimens had a plastic deformation behavior resulting in a substantially higher ultimate tensile strength (up to 380 MPa) and strain at break (up to 130 %) compared to their bulk counterpart (68 MPa and 8%). Polarized light microscopy confirmed a rearrangement of the internal epoxy network structure during loading, resulting in the plastic deformation of the microscale epoxy. This was further accompanied by in-situ electron microscopy to further determine the deformation behavior of the micro-specimens during tensile loading and make accurate strain measurements using video-extensometry. This work thus provides novel insights on the epoxy material behavior at the confined microscale as present in fiber reinforced composite materials. journalArticle original public Article A1 published published ugent 5 Olivier Verschatse Olivier Verschatse aut author 974442908376 0000-0001-7732-6007 Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department 3E016519 3c0a4b92-b36f-11e9-9b22-19a03077e1f4 2019-10-01 2022-09-30 01B03518 320e7057-5b7c-11e9-ac93-1bffacd2a7e2 2018-06-01 2020-05-31 01J02013 23e0ac1b-2d66-4695-b51c-6f6965e4da3d 2013-03-01 2017-12-31 01P03418 b2c0136d-5a95-11e9-b3e1-37a68b033e1d 2019-01-01 2019-09-30 2073-4360 2020 12 11 2581 2020 Technology and Engineering Scanning Electron Microscopy (SEM) micromechanical testing microscale yielding plasticity COMPOSITE-MATERIALS FRACTURE-TOUGHNESS TENSILE PROPERTIES STRENGTH RESIN POLYMER info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8679816/file/8679818 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 5763743 bytes Verschatse_2020_-_In-situ_microscale_ductility_in_a_quasi_brittle_epoxy.pdf Verschatse, Olivier, Lode Daelemans, Wim Van Paepegem, and Karen De Clerck. 2020. “In-Situ Observations of Microscale Ductility in a Quasi-Brittle Bulk Scale Epoxy.” POLYMERS 12 (11). doi:10.3390/polym12112581.

Yet they are prone to delamination between the reinforcing plies, which in turn limits the damage resistance of many applications. This is especially true for the interfaces between dissimilar reinforcing plies that are often encountered in actual components, e.g. differences in fibre orientation, fibre material or ply architecture, where high interlaminar stresses can occur. Nanofibrous toughening veils are known to increase the damage resistance when inserted between similar reinforcing plies, but it is currently unknown how they perform when delamination occurs at dissimilar interfaces. Here, the nanofibre toughening of frequently encountered dissimilar interfaces such as occurring between multidirectionally stacked unidirectional fibre plies (+45 degrees/-45 degrees), multistructural stackings (unidirectional versus fabrics) and multimaterial configurations (glass fibres versus carbon fibres) are analysed. These interfaces largely exert their influence on the crack path during delamination and thus alter the effectiveness of nanofibre toughening. Poly(ether-block-amide) nanofibres of the biosourced polyamide 11 family result in a large increase in mode I and mode II interlaminar fracture toughness for all the tested dissimilar interfaces. We show that their effectiveness however depends on the underlying delamination mechanics present in different dissimilar interfaces. (c) 2020 The Authors. Published by Elsevier Ltd.

Interleaving nanofibrous veils can potentially solve the issue of the limited delamination resistance encountered in composite laminates, but industrial upscaling has always been impeded by one or more critical factors. These constraining factors include a limited temperature stability of the nanofibers, a lack in simultaneous mode I and II delamination performance increase and the complexity of the electrospinning system because non-commercial polymers or specialty nanofibers (e.g. coaxial) are required. In this paper, a robust electrospinning system is proposed that is the first to overcome all major hurdles to make nanofiber toughening industrially viable. A new class of nanofibers based on biosourced polyamide 11 and its poly(ether-block-amide) co-polymers is used to deal with those shortcomings. The nanofibers have tuneable diameters down to 50 nm and cross-section morphologies ranging from circular to ribbon-shaped. The key to this work is the fundamental underpinning of the toughening effect using a broad range of interleaves with different mechanical and thermal properties, fiber diameters and fiber morphologies, all produced from the same bio-based base polymer. Generally, round and thin nanofibers performed better than larger and ribbon-like fibers. The relationship between the fiber morphology and the delamination performance is further underpinned using detailed analysis of the fracture surface. Ultimately, this results in a range of optimized nanofibrous veils capable of improving the delamination resistance considerably without suffering from the aforementioned drawbacks. journalArticle original public Article A1 published published ugent 2 Timo Meireman Timo Meireman aut author 972580996713 Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Sander Rijckaert Sander Rijckaert aut author 977613653975 0000-0003-4447-0867 Hubert Rahier Hubert Rahier aut author Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department 001D05703 d73db4b9-21d4-4a57-b31f-62c79ca4304d 2003-10-01 2005-09-30 178TW1215 6aa08433-5d75-4c9e-9d23-aab37736aa7b 2015-01-01 2018-12-31 3E016519 3c0a4b92-b36f-11e9-9b22-19a03077e1f4 2019-10-01 2022-09-30 01P03418 b2c0136d-5a95-11e9-b3e1-37a68b033e1d 2019-01-01 2019-09-30 0266-3538 1879-1050 2020 193 108126 2020 Technology and Engineering Nano composites Matrix cracking Fiber/matrix bond Fiber bridging Poly(ether-block-amide) (PEBA) INTERLAMINAR FRACTURE-TOUGHNESS MODE-I ELECTROSPUN NANOFIBERS INTERLAYERS BEHAVIOR SOLVENT info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8656395/file/8656398 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 3310668 bytes Gepubliceerde_paper_-_delamination_resistant_composites_---Timo.pdf https://biblio.ugent.be/publication/8656395/file/8694808 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 2430831 bytes Accepted_manuscript.pdf Meireman, Timo, Lode Daelemans, Sander Rijckaert, Hubert Rahier, Wim Van Paepegem, and Karen De Clerck. 2020. “Delamination Resistant Composites by Interleaving Bio-Based Long-Chain Polyamide Nanofibers through Optimal Control of Fiber Diameter and Fiber Morphology.” COMPOSITES SCIENCE AND TECHNOLOGY 193. doi:10.1016/j.compscitech.2020.108126.

This is especially true for polymer materials and their composites as their viscoelastic nature results in time-dependent material behaviour and any measurement uncertainties or errors amplify in long-term predictions. To measure this behaviour at smallest loadings, Dynamic Mechanical Analysis (DMA) is frequently declared as an ideal method. However, the measurement accuracy and repeatability of this method is strongly influenced by (i) the testing fixture and corresponding loading mode, (ii) the sample preparation and (iii) the plotting scale to interpret the test results. In this study, relevant experimental parameters were found for DMA and a proper procedure was designed, which was then applied to measure the viscoelastic behaviour of a highly temperature and creep resistant thermoplastic polymer (polyethersulfone) and of a highly graphite filled polypropylene composite. In combination with finite element simulations and in-situ strain measurements by digital image correlation (DIC), the main influences on measurement accuracy of three-point-bending DMA were identified and subsequently used to determine measurement guidelines. Using these guidelines, DMA measurements allow quantitative determination of the viscoelastic response for rigid polymer and composite materials. journalArticle original public Article A1 published published ugent 3 Joanna Schalnat Joanna Schalnat aut author 976703632210 David Garoz Gómez David Garoz Gómez aut author 000151210973 802001598415 972908523778 0000-0003-2110-0118 UGent Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Ives De Baere Ives De Baere aut author 801001866905 977854465771 0000-0002-6846-0981 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department 3E016519 3c0a4b92-b36f-11e9-9b22-19a03077e1f4 2019-10-01 2022-09-30 01P03418 b2c0136d-5a95-11e9-b3e1-37a68b033e1d 2019-01-01 2019-09-30 0142-9418 1873-2348 2020 91 106799 2020 Technology and Engineering DMA Accuracy Repeatability 3-Point-bending PESU Technoform-PP GUIDELINES info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8676908/file/8676909 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 7076549 bytes Schalnat2020Influencing.pdf https://biblio.ugent.be/publication/8676908/file/8694783 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1596198 bytes Accepted_manuscript.pdf Schalnat, Joanna, David Garoz Gómez, Lode Daelemans, Ives De Baere, Karen De Clerck, and Wim Van Paepegem. 2020. “Influencing Parameters on Measurement Accuracy in Dynamic Mechanical Analysis of Thermoplastic Polymers and Their Composites.” POLYMER TESTING 91. doi:10.1016/j.polymertesting.2020.106799.

Here, we report such translation going from the Felix 3.0 to Prusa i3 MK3 printer by adjusting the flow rate and overlap of strands, utilizing an in-house developed blend of polylactic acid (PLA) and poly(butylene adipate-co-terephthalate) (PBAT). We perform a sensitivity analysis for the Prusa printer, covering variations in nozzle temperature, nozzle diameter, layer thickness, and printing speed (T-nozzle, d(nozzle), LT, and v(print)), aiming at minimizing anisotropy and improving interlayer bonding. Higher mass, larger width, and thickness are obtained with larger d(nozzle), lower v(print), higher LT, and higher T-nozzle. A higher v(print) results in less tensile strain at break, but it remains at a high strain value for samples printed with d(nozzle) equal to 0.5 mm. v(print) has no significant effect on the tensile modulus and tensile and impact strength of the samples. If LT is fixed, an increased d(nozzle) is beneficial for the tensile strength, ductility, and impact strength of the printed sample due to better bonding from a wider raster structure, while an increased LT leads to deterioration of mechanical properties. If the ratio d(nozzle)/LT is greater than 2, a good tensile performance is obtained. An improved T-nozzle leads to a sufficient flow of material, contributing to the performance of the printed device. The considerations brought forward result in a deeper understanding of the FFF process and offer guidance about parameter selection. The optimal d(nozzle)/v(print)/LT/T-nozzle combination is 0.5 mm/120 mm s(-1)/0.15 mm/230 degrees C. journalArticle original public Article A1 published published ugent 5 Sisi Wang Sisi Wang aut author 000160916128 802002436857 979929499370 Dagmar D'hooge Dagmar D'hooge aut author 802000024082 973689492909 0000-0001-9663-9893 TW11 Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Hesheng Xia Hesheng Xia aut author Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Ludwig Cardon Ludwig Cardon aut author 802000179080 972410561043 0000-0002-4019-612X TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department 01P03418 b2c0136d-5a95-11e9-b3e1-37a68b033e1d 2019-01-01 2019-09-30 3E016519 3c0a4b92-b36f-11e9-9b22-19a03077e1f4 2019-10-01 2022-09-30 2073-4360 2020 12 11 2573 2020 Technology and Engineering printing parameter mechanical property printer transferability MECHANICAL-PROPERTIES IMPACT STRENGTH PLA FDM PROPERTY info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8681095/file/8681096 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 6977452 bytes 59._Dhooge-The_Transferability_and_Design_of_Commercial_Printer_Settings_in_PLAPBAT_Fused_Filament_Fabrication.pdf Wang, Sisi, Dagmar D’hooge, Lode Daelemans, Hesheng Xia, Karen De Clerck, and Ludwig Cardon. 2020. “The Transferability and Design of Commercial Printer Settings in PLA/PBAT Fused Filament Fabrication.” POLYMERS 12 (11). doi:10.3390/polym12112573.

Bionanocomposites were obtained through the incorporation of an organomodified montmorillonite (C30B) at 3 wt.%. The main features of the processing and physico-chemical characterization of films and injected samples were assessed and the influence of the components on the chemical, thermal and mechanical properties of the bionanocomposites was investigated. The results indicated that plasticized PLA/PHBV/C30B bionanocomposites present optimal mechanical properties for sanitary applications. Moreover, plasticized PLA/PHBV could lead to finely tuned biomaterials able to form electrospun nanofibers. journalArticle original public Article A1 published published ugent Clément Lacoste Clément Lacoste aut author Benjamin Gallard Benjamin Gallard aut author José-Marie Lopez-Cuesta José-Marie Lopez-Cuesta aut author Özlem İpek Kalaoglu Altan Özlem İpek Kalaoglu Altan aut author 000091814136 802003037550 975697430594 UGent Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department 41A09117 035f6009-5e69-457b-8ff6-598f0e66069f 2017-06-01 2020-07-31 2079-4983 2020 11 3 64 2020 Technology and Engineering biopolymer blends PLA PHBV nanocomposite FILMS PLLA/PHBV info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8675595/file/8675596 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 15111720 bytes jfb-11-00064-v2.pdf Lacoste, Clément, Benjamin Gallard, José-Marie Lopez-Cuesta, Özlem İpek Kalaoglu Altan, and Karen De Clerck. 2020. “Development of Bionanocomposites Based on Poly(3-Hydroxybutyrate-Co-3-Hydroxyvalerate)/Polylactide Blends Reinforced with Cloisite 30B.” JOURNAL OF FUNCTIONAL BIOMATERIALS 11 (3). doi:10.3390/jfb11030064.

In this work, the Forster resonance energy transfer (FRET) of dye-functionalized poly(2-ethyl-2-oxazoline) (PEtOx) was studied to evaluate the effect of dye positioning and polymer chain length on the FRET efficiency. Therefore, both alpha (initiating terminus)- or omega (terminal chain end)-fluorophore single labeled and dual alpha,omega-fluorescent dye labeled PEtOx were prepared via cationic ring opening polymerization (CROP) using 1-(bromomethyl)pyrene as the initiator and/or 1-pyrenebutyric acid or coumarin 343 as the terminating agent, yielding well-defined PEtOx with high labeling efficiency (over 91%). Fluorescence studies revealed that intramolecular FRET is most efficient for heterotelechelic PEtOx containing both pyrene and coumarin 343 fluorophores as chain ends, as expected. A strong dependence of the energy transfer on the chain length was found for these dual labeled polymers. The polymers were tested in both dilute organic (chloroform) and aqueous media revealing a higher FRET efficiency in water due to the enhanced emissive properties of pyrene. The application of dual labeled polymers as fluorescent probes for temperature sensing was demonstrated based on the lower critical solution temperature behavior of the PEtOx. Furthermore, these polymers could be successfully processed into fibers and thin films. Importantly, the fluorescence properties were retained in the solid state without decreasing the FRET efficiency, thus opening future possibilities for application of these materials in solar cells and/or sensors. journalArticle original public Article A1 published published ugent 4 Ronald Merckx Ronald Merckx aut author 974260040744 0000-0002-2867-0888 Thomas Swift Thomas Swift aut author Ryan Rees Ryan Rees aut author Joachim F.

Within these applications, poly(2-alkyl/aryl-2-oxazoline)s (PAOx) are emerging as a popular matrix due to excellent biocompatibility and miscibility with other polymers. However, as much is known of PAOx miscibility with other biocompatible polymer systems, so little is known of the miscibility within the PAOx class. We show the remarkable phase separation of two important, structurally alike, amorphous PAOx, i.e., poly(2-ethyl2-oxazoline) and poly(2-n-propyl-2-oxazoline), that occurs when the polymers' number-average molar mass exceeds 10 kg.mol(-1). The (im)miscibility as a function of average molar mass is experimentally investigated by thermal analysis, theoretically underpinned by the Flory-Huggins lattice theory, and visualized by fluorescence microscopy in both films and nanofibers, the latter being a high-potential support material in biomedicine. These results provide important knowledge on PAOx (im)miscibility which has a crucial impact on the behavior of the many final end products they are investigated for. journalArticle original public Article A1 published published ugent 2 Ella Schoolaert Ella Schoolaert aut author 000100318410 802002133935 975208259089 0000-0003-4345-8225 UGent Ronald Merckx Ronald Merckx aut author 974260040744 0000-0002-2867-0888 Jana Becelaere Jana Becelaere aut author 977861082888 0000-0001-5024-3308 Melissa Everaerts Melissa Everaerts aut author Joachim Van Guyse Joachim Van Guyse aut author 000080062786 802001924676 979806612797 Ondrej Sedlacek Ondrej Sedlacek aut author 802002515063 977034650467 UGent BRUNO DE GEEST BRUNO DE GEEST aut author 870110440223 UGent Guy Van den Mooter Guy Van den Mooter aut author Dagmar D'hooge Dagmar D'hooge aut author 802000024082 973689492909 0000-0001-9663-9893 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Richard Hoogenboom Richard Hoogenboom aut author 802000620432 975196852903 0000-0001-7398-2058 WE07 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Organic and Macromolecular Chemistry WE07 sht department 3G060518 68c7d40e-8a7e-479e-8231-436053702888 2018-01-01 2021-12-31 0024-9297 1520-5835 2020 53 17 7590 7600 2020 Chemistry SOLID DISPERSIONS DRUG-DELIVERY POLY(2-OXAZOLINE)S MISCIBILITY NANOFIBERS SOLUBILITY FORMULATION BLENDS info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/8676370/file/8676371 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 4334461 bytes 50._DHOOGE-_immiscibility_if_chemically_alike_amorphous.pdf Schoolaert, Ella, Ronald Merckx, Jana Becelaere, Melissa Everaerts, Joachim Van Guyse, Ondrej Sedlacek, BRUNO DE GEEST, Guy Van den Mooter, Dagmar D’hooge, Karen De Clerck, and Richard Hoogenboom. 2020. “Immiscibility of Chemically Alike Amorphous Polymers : Phase Separation of Poly(2-Ethyl-2-Oxazoline) and Poly(2‑n‑propyl-2- Oxazoline).” MACROMOLECULES 53 (17): 7590–7600. doi:10.1021/acs.macromol.0c00970.

Wicking and advanced contact angle experiments demonstrate the high potential for applications requiring specific interactions with aqueous media. PnPrOx is a popular member among the biocompatible poly(2-oxazoline)s due to its thermoresponsiveness in aqueous solutions, enabling the production of ‘smart materials’. On material level, however, many interesting properties of this polymer remain undiscovered. Electrospinning is an ideal technique to transfer the properties observed in solutions to end-material properties, as the polymer is processed into highly porous, nanofibrous membranes. PnPrOx' electrospinnability is here investigated in environmentally friendly ethanol/water solvent systems, ensuring industrial scalability. The nanofibrous membranes show increased hydrophobicity exhibiting the rose-petal effect. Upon functionalization with tannic acid, the hydrophobic membranes are transformed into hydrophilic nanofibers showing water-stability in both fresh and salty water, even below the polymer cloud point temperature. By varying the tannic acid amount, the hydrophilicity can be fine-tuned as the contact area between water droplets and surface, the rate and manner of water uptake and the extent of the rose-petal effect can be manipulated easily. Hence an interesting material is designed for applications in which water caption and transport are important. journalArticle original public Article A1 published published ugent 4 Ella Schoolaert Ella Schoolaert aut author 000100318410 802002133935 975208259089 0000-0003-4345-8225 UGent Luisa Cossu Luisa Cossu aut author 000161455587 Jana Becelaere Jana Becelaere aut author 977861082888 0000-0001-5024-3308 Joachim Van Guyse Joachim Van Guyse aut author 000080062786 802001924676 979806612797 Ali Tigrine Ali Tigrine aut author 802002407050 000090191610 975542025985 0000-0003-1639-1344 WE07 Maarten Vergaelen Maarten Vergaelen aut author 000080251635 802001657928 978043257578 UGent Richard Hoogenboom Richard Hoogenboom aut author 802000620432 975196852903 0000-0001-7398-2058 WE07 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Organic and Macromolecular Chemistry WE07 sht department 3G060518 68c7d40e-8a7e-479e-8231-436053702888 2018-01-01 2021-12-31 0264-1275 1873-4197 2020 192 108747 2020 Technology and Engineering Mechanical Engineering General Materials Science Mechanics of Materials Poly(2-n-propyl-2-oxazoline) Nanofibers Wettability Rose-petal Contact angle Tannic acid CRITICAL SOLUTION TEMPERATURE HYDROGEN-BONDED MULTILAYERS SUPERHYDROPHOBIC SURFACES SILVER NANOPARTICLES TANNIC-ACID POLY(2-OXAZOLINE)S POLYMER WATER MEMBRANE PH info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8667396/file/8667409 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 2375962 bytes MaterialsDesign_2020.pdf Schoolaert, Ella, Luisa Cossu, Jana Becelaere, Joachim Van Guyse, Ali Tigrine, Maarten Vergaelen, Richard Hoogenboom, and Karen De Clerck. 2020. “Nanofibers with a Tunable Wettability by Electrospinning and Physical Crosslinking of Poly(2-n-Propyl-2-Oxazoline).” MATERIALS & DESIGN 192. doi:10.1016/j.matdes.2020.108747.

In our work stimuli-sensitive dyes are incorporated in a polymeric nanofibrous matrix by the process of solvent electrospinning. An important challenge that is tackled here is dye-immobilization as to design a stable sensor. In addition, an ecological friendly production process is aimed for resulting in the use of “green” solvents such as water and ethanol. However, the use of hydrophilic polymers poses some challenges with regard to the solvent electrospinning process, which are addressed in this work as well. conference proceedingsPaper public C1 published published ugent Ella Schoolaert Ella Schoolaert aut author 000100318410 802002133935 975208259089 0000-0003-4345-8225 UGent Richard Hoogenboom Richard Hoogenboom aut author 802000620432 975196852903 0000-0001-7398-2058 WE07 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Organic and Macromolecular Chemistry WE07 sht department AUTEX (Association of Universities for Textiles) Ghent, Belgium 2019-06-11 2019-06-15 3G060518 68c7d40e-8a7e-479e-8231-436053702888 2018-01-01 2021-12-31 9789079892068 AUTEX 2019 2019 Technology and Engineering Chemistry Solvent electrospinning nanofibers optical sensors info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8620290/file/8620298 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 662122 bytes 2A_0127.pdf Schoolaert, Ella, Richard Hoogenboom, and Karen De Clerck. 2019. “Going from Polymer to Application : Solvent Electrospinning of Optical Nanofibrous Sensors.” In AUTEX2019 : 19th World Textile Conference on Textiles at the Crossroads.

Cloisite was added to improve the stiffness of the blend. The blends were made into filament suitable for extrusion-based additive manufacturing. Melt flow index of the filament and mechanical properties of the printed bars were tested. Preliminary results showed that the melt flow index increases significantly with cloisite and the modulus of polylactic acid/poly(butylene adipate-co-terephthalate) improved slightly. The notched impact strength of the blend increased with increasing content of cloisite, and it increased significantly after annealing, especially for blends without cloisite.

The development of more inert nanofibers with higher thermal and chemical resistance extends the application field. Silica nanofibrous membranes produced by direct electrospinning of a sol–gel solution without a sacrificing carrier meet these challenging demands. A combination of hydrolysis and condensation reactions of the tetraethoxysilane (TEOS) precursor, results in dense silica nanofibers with superior mechanical properties, without a rough and uneven surface, allowing the use in advanced engineering applications. conference proceedingsPaper public C1 published published ugent Eva Loccufier Eva Loccufier aut author 802002671374 974161061035 0000-0001-7045-2721 TW11 Jozefien Geltmeyer Jozefien Geltmeyer aut author 000070582957 975000449525 0000-0002-1281-2968 Dolores Esquivel Dolores Esquivel aut author Dagmar D'hooge Dagmar D'hooge aut author 802000024082 973689492909 0000-0001-9663-9893 TW11 Klaartje De Buysser Klaartje De Buysser aut author 801001571962 978828372447 0000-0001-7462-2484 WE06 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Chemistry WE06 sht department AUTEX (Association of Universities for Textiles) Ghent, Belgium 2019-06-11 2019-06-15 9789079892068 AUTEX 2019 2019 Technology and Engineering Electrospinning Silica Sol-gel synthesis Hydrophobicity Viscosity info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8620308/file/8620309 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1429763 bytes 2B_0505.pdf https://biblio.ugent.be/publication/8620308/file/8628435 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 3460084 bytes presentation.pdf Loccufier, Eva, Jozefien Geltmeyer, Dolores Esquivel, Dagmar D’hooge, Klaartje De Buysser, and Karen De Clerck. 2019. “Electrospinning of Silica Nanofibers without Carrier Polymer for Advanced Engineering Applications.” In AUTEX2019 : 19th World Textile Conference on Textiles at the Crossroads.

However, most of the current repellents are volatile in nature and must be frequently re-applied as their efficacy is only limited to a short period of time. Therefore, a slow release and abrasion-resistant mechanism is needed for prolonging the protection time of the repellents. The focus of this study is on the direct micro-encapsulation of repellents from an emulsion and integration of already encapsulated repellents into nanofibres via electrospinning. Different repellents were electrospun in polyvinyl alcohol (PVA) nanofibrous structures, namely p-menthane-3,8-diol micro-capsules, permethrin, chilli and catnip oil. The repellents were successfully incorporated in the nanofibres and the tensile properties of the resulting samples did not have a significant change. This means that the newly created textiles were identical to current PVA nanofibrous textiles with the added benefit of being mosquito repellent. Principally, all incorporated repellents in the nanofibrous structures showed a significantly reduced number of mosquito landings compared to the control. Consequently, the currently described method resulted in a new and very effective repelling textile material that can be used in the prevention against mosquito-associated diseases. journalArticle original public Article VABB-1 not-approved A1 published published ugent 8 Lucy Ciera Lucy Ciera aut author Lynda Beladjal Lynda Beladjal aut author 801001276417 974387308481 0000-0002-5755-7235 UGent Lieve Van Landuyt Lieve Van Landuyt aut author 801001285006 TW11 David Menger David Menger aut author Maarten Holdinga Maarten Holdinga aut author Johan Mertens Johan Mertens aut author 978235956061 UGent Lieva Van Langenhove Lieva Van Langenhove aut author 801000648543 972198930382 0000-0001-9802-7399 TW11 TW18 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Tom Gheysens Tom Gheysens aut author 002000654908 801001793648 971661450756 0000-0002-8185-8986 UGent Department of Biology WE11 sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Organic and Macromolecular Chemistry WE07 sht department 2054-5703 2019 6 8 182139 2019 Medicine and Health Sciences Technology and Engineering electrospinning mosquito repellent emulsion micro-capsules INSECT REPELLENTS ENCAPSULATION MORPHOLOGY info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8627257/file/8627465 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1622748 bytes 8627260.pdf Ciera, Lucy, Lynda Beladjal, Lieve Van Landuyt, David Menger, Maarten Holdinga, Johan Mertens, Lieva Van Langenhove, Karen De Clerck, and Tom Gheysens. 2019. “Electrospinning Repellents in Polyvinyl Alcohol-Nanofibres for Obtaining Mosquito-Repelling Fabrics.” ROYAL SOCIETY OPEN SCIENCE 6 (8). doi:10.1098/rsos.182139.

Although many studies showcase large increases in delamination resistance, these are typically obtained under either Mode I or Mode II loading and for a wide variety of nanofibres. Here, we present a more general approach towards simultaneous excellent Mode I and Mode II delamination resistance using a single nanofibre system without the need for additional chemical modification steps or speciality polymers. It is illustrated based on the concept of interdiffusion of polycaprolactone nanofibres during the curing process into the epoxy matrix resin for improved adhesion. The results show that for a simultaneous increase in Mode I and Mode II delamination resistance, the adhesion and the fibre morphology of the nanofibres are crucial. The methodology is then expanded to allow for industrial relevant working windows by core-shell structured polyamide/polycaprolactone nanofibres. This approach results in a of 650 ± 50 J m-2 (+ca. 60% vs. virgin material) and a of 3160 ± 35 J m-2 (+ca. 60% vs. virgin material). journalArticle original public Article A1 published published ugent 2 Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Nuray Kizildag Nuray Kizildag aut author 000161189849 802002292266 973174641965 UGent Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Dagmar D'hooge Dagmar D'hooge aut author 802000024082 973689492909 0000-0001-9663-9893 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department 01J02013 23e0ac1b-2d66-4695-b51c-6f6965e4da3d 2013-03-01 2017-12-31 01B03518 320e7057-5b7c-11e9-ac93-1bffacd2a7e2 2018-06-01 2020-05-31 01P03418 b2c0136d-5a95-11e9-b3e1-37a68b033e1d 2019-01-01 2019-09-30 0266-3538 1879-1050 2019 175 143 150 2019 Technology and Engineering General Engineering Ceramics and Composites info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8612400/file/8612401 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 2341775 bytes Journal version.pdf https://biblio.ugent.be/publication/8612400/file/8612402 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 2085363 bytes postprint.pdf https://biblio.ugent.be/publication/8612400/file/8612403 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1158194 bytes Supplementary Information.pdf Daelemans, Lode, Nuray Kizildag, Wim Van Paepegem, Dagmar D’hooge, and Karen De Clerck. 2019. “Interdiffusing Core-Shell Nanofiber Interleaved Composites for Excellent Mode I and Mode II Delamination Resistance.” COMPOSITES SCIENCE AND TECHNOLOGY 175: 143–150. doi:10.1016/j.compscitech.2019.03.019.

For filament printing at 210 °C, the PLA crystallinity increased significantly upon annealing. Specifically, for 2 h of annealing at 100 °C, the fracture surface became sufficiently coarse such that the PLA notched impact strength increased significantly (15 kJ m−2). The Vicat softening temperature (VST) increased to 160 °C, starting from an annealing time of 0.5 h. Similar increases in VST were obtained by blending with PHB (20 wt.%) at a lower printing temperature of 190 °C due to crystallization control. For the blend, the strain at break increased due to the presence of a second phase, with annealing only relevant for enhancing the modulus.</jats:p> journalArticle original public Article A1 published published ugent 4 Sisi Wang Sisi Wang aut author 000160916128 802002436857 979929499370 Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Rudinei Fiorio Rudinei Fiorio aut author 000181256523 802002862445 974407662418 UGent Maling Gou Maling Gou aut author Dagmar D'hooge Dagmar D'hooge aut author 802000024082 973689492909 0000-0001-9663-9893 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Ludwig Cardon Ludwig Cardon aut author 802000179080 972410561043 0000-0002-4019-612X TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department 01P03418 b2c0136d-5a95-11e9-b3e1-37a68b033e1d 2019-01-01 2019-09-30 3S009618 d937d58c-be65-11e9-ace9-8bf558aeac68 2018-01-01 2022-09-09 2073-4360 2019 11 9 1529 2019 Technology and Engineering extrusion-based additive manufacturing poly(lactic acid) poly(3-hydroxybutyrate) annealing notched impact strength info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8628993/file/8628994 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1828255 bytes polymers-11-01529.pdf Wang, Sisi, Lode Daelemans, Rudinei Fiorio, Maling Gou, Dagmar D’hooge, Karen De Clerck, and Ludwig Cardon. 2019. “Improving Mechanical Properties for Extrusion-Based Additive Manufacturing of Poly(Lactic Acid) by Annealing and Blending with Poly(3-Hydroxybutyrate).” POLYMERS 11 (9). doi:10.3390/polym11091529.

Three different ultraviolet (UV) irradiation methods, i.e. pre-crosslinking before electrospinning, in-situ crosslinking during electrospinning and post-crosslinking after electrospinning, were used to prepare crosslinked nanofibers. The influence of UV-irradiation at these different stages of the nanofiber production process was investigated in terms of alterations in viscosity, nanofiber morphology and water stability of the fibers. It was shown that pre-crosslinking the polymer solutions had a great influence on the solution viscosity which could both positively or negatively alter the stability of the electrospinning process. Whereas the strategy of crosslinking nanofibers during the production process did not lead to uniform nor water-stable nanofibers, the pre-crosslinking and post-crosslinking strategies greatly increased the water stability of the nanofibers. In both techniques the crosslinking density and therefore water solubility can be easily tuned by manipulating the polymer concentration, UV-irradiation time and membrane thickness. Complete insolubility, i.e. the formation of crosslinked networks, was achieved by the post-cross linking strategy. This work provides straightforward methods to increase the water stability of the PEtOx nanofibers, which will definitely be of great value to biomedical applications such as drug delivery and tissue engineering. journalArticle original public Article A1 published published ugent 4 Yin Li Yin Li aut author 000131149050 802001676621 975949733557 Maarten Vergaelen Maarten Vergaelen aut author 000080251635 802001657928 978043257578 UGent Ella Schoolaert Ella Schoolaert aut author 000100318410 802002133935 975208259089 0000-0003-4345-8225 UGent Richard Hoogenboom Richard Hoogenboom aut author 802000620432 975196852903 0000-0001-7398-2058 WE07 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Organic and Macromolecular Chemistry WE07 sht department 3G060518 68c7d40e-8a7e-479e-8231-436053702888 2018-01-01 2021-12-31 0014-3057 2019 112 24 30 2019 Chemistry Technology and Engineering Electrospinning Poly(2-ethyl-2-oxazoline) Benzophenone UV-irradiation Crosslinking Nanofibers POLY(ETHYLENE OXIDE) NANOPARTICLES CHEMISTRY FIBERS info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8586957/file/8586958 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1657408 bytes preprint PAOX BZP.pdf https://biblio.ugent.be/publication/8586957/file/8586959 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1369324 bytes 1-s2.0-S0014305718322031-main.pdf Li, Yin, Maarten Vergaelen, Ella Schoolaert, Richard Hoogenboom, and Karen De Clerck. 2019. “Effect of Crosslinking Stage on Photocrosslinking of Benzophenone Functionalized Poly(2-Ethyl-2-Oxazoline) Nanofibers Obtained by Aqueous Electrospinning.” EUROPEAN POLYMER JOURNAL 112: 24–30. doi:10.1016/j.eurpolymj.2018.12.030. the first two authors contributed equally as first author to the manuscript Ghent University Library pug01:8586957 2019-01-02T11:11:27Z 2026-03-31T14:54:18Z eng public 801000739277 2 3 false higher-education 2019 2 3 false higher-education 2019 http://hdl.handle.net/1854/LU-8644205 10.1016/j.eurpolymj.2019.109218 000498309000063 eng No license (in copyright) Poly(2-ethyl-2-oxazoline)s (PEtOx) have received substantial attention for various potential biomedical applications, yet they have not been explored as scaffold materials to any extensive degree. A major challenge to open up future applications is to overcome the poor water stability of these materials. We here propose a universal crosslinking strategy for these materials based on a partial acidic hydrolysis of PEtOx to poly[(2-ethyl-2-oxazoline)-co-(ethylenimine)] (PEtOx-EI) followed by exposure to glutaraldehyde vapour to create water-stable scaffolds. To demonstrate the utility of this approach two different fabrication techniques were used to make 2-and 3-dimensional structures, namely solution electrospinning and fused deposition modelling (FDM). Because the partial hydrolysis results in increased hydrophilicity, the crosslinking conditions for the fine PEtOx-EI nanofibers were carefully tuned to enable crosslinking of the nanofibers prior to a loss of the nanofibrous morphology. Conversely, for the thicker FDM printed PEtOx-EI structures the crosslinking conditions are more tolerant. Crosslinking with glutaraldehyde vapour provided water-stability to both 2D and 3D constructs, which is an important asset for biomedical applications. journalArticle original public Article A1 published published ugent 4 Özlem İpek Kalaoglu Altan Özlem İpek Kalaoglu Altan aut author 000091814136 802003037550 975697430594 UGent Yin Li Yin Li aut author 000131149050 802001676621 975949733557 Rebecca McMaster Rebecca McMaster aut author Aby Shaw Aby Shaw aut author Zhanyao Hou Zhanyao Hou aut author 000131333552 802001770284 978130174228 0000-0002-6189-1578 UGent Maarten Vergaelen Maarten Vergaelen aut author 000080251635 802001657928 978043257578 UGent Richard Hoogenboom Richard Hoogenboom aut author 802000620432 975196852903 0000-0001-7398-2058 WE07 Tim R Dargaville Tim R Dargaville aut author Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Organic and Macromolecular Chemistry WE07 sht department 3G060518 68c7d40e-8a7e-479e-8231-436053702888 2018-01-01 2021-12-31 0014-3057 1873-1945 2019 120 109218 2019 Technology and Engineering Chemistry Electrospinning Fused deposition modelling Poly(2-ethyl-2-oxazoline) Glutaraldehyde Crosslinking Bioextrusion TISSUE ENGINEERING APPLICATIONS 3-DIMENSIONAL SCAFFOLDS PORE-SIZE NANOFIBERS POLY(2-OXAZOLINE)S FABRICATION HYDROGELS info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/8644205/file/8644211 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 10515254 bytes 1-s2.0-S0014305719313588-main.pdf Kalaoglu Altan, Özlem İpek, Yin Li, Rebecca McMaster, Aby Shaw, Zhanyao Hou, Maarten Vergaelen, Richard Hoogenboom, Tim R Dargaville, and Karen De Clerck. 2019. “Crosslinking of Electrospun and Bioextruded Partially Hydrolyzed Poly(2-Ethyl-2-Oxazoline) Using Glutaraldehyde Vapour.” EUROPEAN POLYMER JOURNAL 120. doi:10.1016/j.eurpolymj.2019.109218.

The development of more inert nanofibers with higher thermal and chemical resistance extends the application field to high-end purification. Silica nanofibrous membranes produced by direct electrospinning of a sol-gel solution without a sacrificing carrier, starting from tetraethoxysilane, meet these challenging requirements. After electrospinning the membrane is highly hydrophobic. Storage under dry conditions preserves this property. Oppositely, a superhydrophilic membrane is obtained by storage under high humidity (month scale). This switch is caused by the reaction of ethoxy groups, present due to incomplete hydrolysis of the precursor, with moisture in the air, resulting in an increased amount of silanol groups. This transition can be accelerated to hour scale by applying a heat treatment, with the additional increase in cross-linking density for temperatures above 400 degrees C, enabling applications that make use of hydrophobic and hydrophilic membranes by tuning the functionalization. It is showcased that upon designing the water repellent or absorbing nature of the silica material, fast gravity-driven membrane separation of heterogeneous azeotropes can be achieved. journalArticle original public Article A1 published published ugent 1 Eva Loccufier Eva Loccufier aut author 802002671374 974161061035 0000-0001-7045-2721 TW11 Jozefien Geltmeyer Jozefien Geltmeyer aut author 000070582957 975000449525 0000-0002-1281-2968 Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Dagmar D'hooge Dagmar D'hooge aut author 802000024082 973689492909 0000-0001-9663-9893 TW11 Klaartje De Buysser Klaartje De Buysser aut author 801001571962 978828372447 0000-0001-7462-2484 WE06 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Chemistry WE06 sht department 3S009618 d937d58c-be65-11e9-ace9-8bf558aeac68 2018-01-01 2022-09-09 01B03518 320e7057-5b7c-11e9-ac93-1bffacd2a7e2 2018-06-01 2020-05-31 178TW1215 6aa08433-5d75-4c9e-9d23-aab37736aa7b 2015-01-01 2018-12-31 1616-301X 1616-3028 2018 28 44 1804138 2018 Chemistry Technology and Engineering electrospun nanofibrous membranes heterogeneous azeotrope separation silica wettability switch ELECTROSPUN NANOFIBERS WATER SEPARATION FLUX SUPERHYDROPHOBICITY ULTRAFILTRATION MICROFILTRATION PERFORMANCE CONVERSION SURFACES EMULSION info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8574639/file/8574663 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 4388893 bytes Manuscript.pdf https://biblio.ugent.be/publication/8574639/file/8574664 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 3791279 bytes Loccufier_et_al-2018-Advanced_Functional_Materials.pdf Loccufier, Eva, Jozefien Geltmeyer, Lode Daelemans, Dagmar D’hooge, Klaartje De Buysser, and Karen De Clerck. 2018. “Silica Nanofibrous Membranes for the Separation of Heterogeneous Azeotropes.” ADVANCED FUNCTIONAL MATERIALS 28 (44). doi:10.1002/adfm.201804138.

Herein, we present a methodology for the design of degradable diselenide-cross-linked nanofibers by aqueous electrospinning of selenol (SeH)-modified poly(2-ethyl-2-oxazoline) (PEtOx). The selenol groups have been introduced into PEtOx by reacting partially hydrolyzed PEtOx (poly(2-ethyl-2-oxazoline-)-co-ethylenimine (PEtOx-EI)) with gamma-butyroselenolactone, whereby ring-opening upon reaction with the secondary amine groups in the polymer backbone yields selenol side chains. Subsequent aqueous electrospinning of the selenol-containing PEtOx was linked water-stable nanofibers, ascribed to the formation of diselenide cross-links. The effects of changes in the experimental parameters and the influence of the selenium content on the electrospinning process were investigated in detail. Dynamic exchange between the remaining free SeH groups and diselenide bonds formed upon cross-linking enabled a tunable dissolution of the PEtOx-based nanofibers, which could be controlled by changing both the temperature and cross-linking density. Furthermore, the dissolution of the diselenide cross-linked nanofibers could also be induced by the exchange of diselenide groups under ultraviolet (UV) irradiation. journalArticle original public Article A1 published published ugent 2 Yin Li Yin Li aut author 000131149050 802001676621 975949733557 Maarten Vergaelen Maarten Vergaelen aut author 000080251635 802001657928 978043257578 UGent Xiangqiang Pan Xiangqiang Pan aut author Filip Du Prez Filip Du Prez aut author 801000886393 976639179245 0000-0001-7727-4155 WE07 Richard Hoogenboom Richard Hoogenboom aut author 802000620432 975196852903 0000-0001-7398-2058 WE07 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Organic and Macromolecular Chemistry WE07 sht department 3G060518 68c7d40e-8a7e-479e-8231-436053702888 2018-01-01 2021-12-31 0024-9297 1520-5835 2018 51 15 6149 6156 2018 Chemistry Technology and Engineering DRUG-DELIVERY MECHANICAL-PROPERTIES POLYMERIC NANOFIBERS FACILE SYNTHESIS SCAFFOLDS MEMBRANES LINKING BLOCK NANOPARTICLES BIOMATERIALS info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/8586960/file/8586961 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 6349888 bytes PAOx selenelactone printed version.pdf Li, Yin, Maarten Vergaelen, Xiangqiang Pan, Filip Du Prez, Richard Hoogenboom, and Karen De Clerck. 2018. “In Situ Cross-Linked Nanofibers by Aqueous Electrospinning of Selenol-Functionalized Poly(2-Oxazoline)s.” MACROMOLECULES 51 (15): 6149–6156. doi:10.1021/acs.macromol.8b01113.

This plasma dye coating (PDC) procedure immobilizes a preadsorbed layer of a dye functionalized with a radical sensitive group on the surface through radical addition caused by a short plasma treatment. The non-specific nature of the plasmagenerated surface radicals allows for a wide variety of dyes including azobenzenes and sulfonphthaleins, functionalized with radical sensitive groups to avoid significant dye degradation, to be combined with various materials including PP, PE, PA6, cellulose, and PTFE. The wide applicability, low consumption of dye, relatively short procedure time, and the possibility of continuous PDC using an atmospheric plasma reactor make this procedure economically interesting for various applications ranging from simple coloring of a material to the fabrication of chromic sensor fabrics as demonstrated by preparing a range of halochromic materials. journalArticle original public Article A1 published published ugent 2 Lieselot De Smet Lieselot De Smet aut author 000100053072 802002159395 971819515488 Gertjan Vancoillie Gertjan Vancoillie aut author 000060487479 802001083911 973415065357 UGent Peter Minshall Peter Minshall aut author 000141369618 Kathleen Lava Kathleen Lava aut author 802001421589 974160946756 UGent Iline Steyaert Iline Steyaert aut author 000060129993 802001072793 979860756278 UGent Ella Schoolaert Ella Schoolaert aut author 000100318410 802002133935 975208259089 0000-0003-4345-8225 UGent Elke Van De Walle Elke Van De Walle aut author 002004260476 802000699648 972251959272 UGent Peter Dubruel Peter Dubruel aut author 801001311476 978203976171 0000-0002-5928-7726 WE07 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Richard Hoogenboom Richard Hoogenboom aut author 802000620432 975196852903 0000-0001-7398-2058 WE07 Department of Organic and Macromolecular Chemistry WE07 sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department 3G060518 68c7d40e-8a7e-479e-8231-436053702888 2018-01-01 2021-12-31 2041-1723 2018 9 1123 2018 Technology and Engineering Chemistry SURFACE-ACTIVE COMPOUNDS ROSE-BENGAL POLY(ETHYLENE) SURFACES TEXTILE MATERIALS NITRAZINE YELLOW CHEMICAL SENSORS PH BRUSHES NANOFIBERS SULFATE info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8561225/file/8561226 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1621340 bytes Nat-Commun_2018_9_1123.pdf https://biblio.ugent.be/publication/8561225/file/8561227 info:eu-repo/semantics/closedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1621991 bytes s41467-018-03583-4.pdf De Smet, Lieselot, Gertjan Vancoillie, Peter Minshall, Kathleen Lava, Iline Steyaert, Ella Schoolaert, Elke Van De Walle, Peter Dubruel, Karen De Clerck, and Richard Hoogenboom. 2018. “Plasma Dye Coating as Straightforward and Widely Applicable Procedure for Dye Immobilization on Polymeric Materials.” NATURE COMMUNICATIONS 9. doi:10.1038/s41467-018-03583-4. the first two authors contributed equally Ghent University Library pug01:8561225 2018-05-08T07:27:31Z 2026-03-31T14:54:18Z eng public 802000474124 10 1 false higher-education 2018 10 1 false higher-education 2018 http://hdl.handle.net/1854/LU-8556775 eng No license (in copyright) conference poster public C3 published published ugent Ella Schoolaert Ella Schoolaert aut author 000100318410 802002133935 975208259089 0000-0003-4345-8225 UGent Dagmar D'hooge Dagmar D'hooge aut author 802000024082 973689492909 0000-0001-9663-9893 TW11 Richard Hoogenboom Richard Hoogenboom aut author 802000620432 975196852903 0000-0001-7398-2058 WE07 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Eugene Smit Eugene Smit edt editor Department of Materials, Textiles and Chemical Engineering TW11 sht department Stellenbosch Nanofiber Company (Pty) Ltd.

Nanofibers, characterized by high porosity, flexibility, and a large specific surface area, are the ideal material for ultrasensitive, fastresponding, and user-friendly sensor design. Indeed, a large specific surface area increases the sensitivity and response time of the sensor as the contact area with the analyte is enlarged. Thanks to the flexibility of membranes, nanofibrous sensors cannot only be applied in high-end analyte detection, but also in personal, daily use. Many different nanofibrous sensors have already been designed; albeit, the most straightforward and easiest-to-interpret sensor response is a visual change in color, which is of particular interest in the case of warning signals. Recently, many researchers have focused on the design of so-called colorimetric nanofibers, which typically involve the incorporation of a colorimetric functionality into the nanofibrous matrix. Many different strategies have been used and explored for colorimetric nanofibrous sensor design, which are outlined in this feature article. The many examples and applications demonstrate the value of colorimetric nanofibers for advanced optical sensor design, and could provide directions for future research in this area. journalArticle original public Article A1 published published ugent 1 Ella Schoolaert Ella Schoolaert aut author 000100318410 802002133935 975208259089 0000-0003-4345-8225 UGent Richard Hoogenboom Richard Hoogenboom aut author 802000620432 975196852903 0000-0001-7398-2058 WE07 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Organic and Macromolecular Chemistry WE07 sht department 1616-301X 2017 27 38 1702646 2017 Chemistry Technology and Engineering METAL-HALIDE PEROVSKITES QUANTUM-DOT PHOTODETECTORS CHARGE-CARRIER DYNAMICS NARROW-BAND INFRARED PHOTODETECTORS SOLAR-CELLS RECOMBINATION PHOTOVOLTAICS FORMAMIDINIUM PHOTODIODES colorimetric sensors nanofibers optical sensors solvent-electrospinning info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8541242/file/8541245 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 2148906 bytes Manuscript_Colorimetric nanofibers as optical sensors_AFM_Ella Schoolaert.pdf https://biblio.ugent.be/publication/8541242/file/8561079 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 7331377 bytes Colorimetric nanofibers as optical sensors - Ugent access.pdf Schoolaert, Ella, Richard Hoogenboom, and Karen De Clerck. 2017. “Colorimetric Nanofibers as Optical Sensors.” ADVANCED FUNCTIONAL MATERIALS 27 (38). doi:10.1002/adfm.201702646.

Most water-soluble polymers have the inherent limitation of resulting in water-soluble nanofibers, and a tedious chemical cross-linking step is required to reach stable nanofibers. An interesting alternative route is the use of thermoresponsive polymers, such as poly(N-isopropylacrylamide) (PNIPAM), as they are water-soluble beneath their lower critical solution temperature (LCST) allowing low-temperature electrospinning while the obtained nanofibers are water-stable above the LCST. Moreover, PNIPAM nanofibers show major potential to many application fields, including biomedicine, as they combine the well-known on off switching behavior of PNIPAM, thanks to its LCST, with the unique properties of nanofibers. In the present work, based on dedicated turbidity and rheological measurements, optimal combinations of polymer concentration, environmental temperature, and relative humidity are identified allowing, for the first time, the production of continuous, bead-free PNIPAM nanofibers electrospun from water. More specifically, PNIPAM gelation was found to occur well below its LCST at higher polymer concentrations leading to a temperature regime where the viscosity significantly increases without compromising, the polymer solubility. This opens up the ecological, water-based production of uniform PNIPAM nanofibers that are stable in water at temperatures above PNIPAM's LCST, making them suitable for various applications, including drug delivery and switchable cell culture substrates. journalArticle original public Article A1 published published ugent 2 Ella Schoolaert Ella Schoolaert aut author 000100318410 802002133935 975208259089 0000-0003-4345-8225 UGent Paulien Ryckx Paulien Ryckx aut author 000100547469 Jozefien Geltmeyer Jozefien Geltmeyer aut author 000070582957 975000449525 0000-0002-1281-2968 Samarendra Maji Samarendra Maji aut author 802001215768 979452096692 UGent Paul Van Steenberge Paul Van Steenberge aut author 802000264461 975633424843 0000-0001-6244-1299 TW11 Dagmar D'hooge Dagmar D'hooge aut author 802000024082 973689492909 0000-0001-9663-9893 TW11 Richard Hoogenboom Richard Hoogenboom aut author 802000620432 975196852903 0000-0001-7398-2058 WE07 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Organic and Macromolecular Chemistry WE07 sht department 1944-8244 2017 9 28 24100 24110 2017 Chemistry Technology and Engineering POLY-N-ISOPROPYLACRYLAMIDE THERMORESPONSIVE POLYMERS DRUG-RELEASE BIOMEDICAL APPLICATIONS AQUEOUS-SOLUTIONS GENE DELIVERY NANOFIBERS TEMPERATURE SENSORS BEHAVIOR poly(N-isopropylacrylamide) aqueous media electrospinning nanofibers lower critical solution temperature rheology info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8536522/file/8536523 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 2812270 bytes waterborne Electrospinning.pdf https://biblio.ugent.be/publication/8536522/file/8561078 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1694485 bytes Revised Manuscript Waterborne electrospinning.pdf Schoolaert, Ella, Paulien Ryckx, Jozefien Geltmeyer, Samarendra Maji, Paul Van Steenberge, Dagmar D’hooge, Richard Hoogenboom, and Karen De Clerck. 2017. “Waterborne Electrospinning of Poly(N-Isopropylacrylamide) by Control of Environmental Parameters.” ACS APPLIED MATERIALS & INTERFACES 9 (28): 24100–24110. doi:10.1021/acsami.7b05074.

These new woven fabrics with integrated prismatic shaped cavities are produced in one single run eliminating a lot of manual labour and in the case of composites lead to an improved resistance against delamination. In this paper, these fabrics are used to produce composites and concrete elements which are subjected to three point bending tests. The first tests show promising results as well for the composites as for the concrete reinforcement. conference proceedingsPaper public C1 published published ugent Ruben Geerinck Ruben Geerinck aut author 000107011410 802001963072 974477498576 Ives De Baere Ives De Baere aut author 801001866905 977854465771 0000-0002-6846-0981 TW11 Geert De Clercq Geert De Clercq aut author 802000722381 919013370543 977142365937 TW11 Alessandro Proia Alessandro Proia aut author 802001931548 977904928811 0000-0002-6776-5708 TW14 Stijn Matthys Stijn Matthys aut author 801000980060 973084180270 0000-0002-9588-8561 TW14 Jan Ivens Jan Ivens aut author Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Structural Engineering and Building Materials TW14 sht department Ghent, Belgium 2017-10-16 2017-10-18 2017 2017 Technology and Engineering 3D woven fabrics 3D composites 3D concrete reinforcement info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/8548640/file/8565263 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 406462 bytes Ruben_Geerinck.pdf Geerinck, Ruben, Ives De Baere, Geert De Clercq, Alessandro Proia, Stijn Matthys, Jan Ivens, and Karen De Clerck. 2017. “Woven Fabrics with Integrated Prismatic Shaped Cavities for Technical Applications.” In Proceedings of the 6th International Conference on Intelligent Textiles and Mass Customisation.

However, delamination between the reinforcing plies remains a major problem as it limits further breakthrough of these materials. Recently, interleaving electrospun nanofibres between the reinforcing plies has proven to be a viable interlaminar toughening method which can significantly limit the occurrence of delamination failure in composite materials. This presentation will give a thorough insight into the relationship between the electrospun nanofibre properties and the resulting tough composites, and as such, allow for engineering novel and damage resistant nanofiber toughened composites. conference proceedingsPaper public C1 published published ugent Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Timo Meireman Timo Meireman aut author 972580996713 Ives De Baere Ives De Baere aut author 801001866905 977854465771 0000-0002-6846-0981 TW11 Hubert Rahier Hubert Rahier aut author Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Ghent 2017-10-15 2017-10-18 178TW1215 6aa08433-5d75-4c9e-9d23-aab37736aa7b 2015-01-01 2018-12-31 Ghent 2017 2017 Technology and Engineering composites electrospinning delamination mechanical properties info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/8629108/file/8629111 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 280798 bytes S123_DAELEMANS_et_al_1.pdf Daelemans, Lode, Timo Meireman, Ives De Baere, Hubert Rahier, Wim Van Paepegem, and Karen De Clerck. 2017. “Electrospun Nanofibers for Highly Toughened Fibre Reinforced Polymer Composite Laminates.” In International Conference on Intelligent Textiles and Mass Customisation (ITMC2017) : Proceedings.

More recently, interleaving the laminated structures with electrospun (thermoplastic) nanofibrous veils is shown to be a viable toughening method. Where toughening composite laminates with nanofibrous interleaves becomes more and more evident under static conditions, the effectiveness under fatigue loadings has yet to be proven. This article provides insight in the nanofibre toughening mechanisms acting under fatigue conditions. Several nanofibre types with a high potential for toughening are considered. A substantial decrease of the delamination propagation rate up to one order of magnitude was obtained for all tested nanofibre types. Furthermore, two distinct zones of delamination behaviour are observed in nanofibre interleaved laminates on exposure to cyclic loading. These insights reveal the crucial design parameters which allow for the production of nanofibre toughened composites with an improved fatigue life. journalArticle original public Article A1 published published ugent 1 Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Sam van der Heijden Sam van der Heijden aut author 000070168988 802001291348 972120157894 UGent Ives De Baere Ives De Baere aut author 801001866905 977854465771 0000-0002-6846-0981 TW11 Hubert Rahier Hubert Rahier aut author Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department 178TW1215 6aa08433-5d75-4c9e-9d23-aab37736aa7b 2015-01-01 2018-12-31 01J02013 23e0ac1b-2d66-4695-b51c-6f6965e4da3d 2013-03-01 2017-12-31 1359-835X Elsevier BV 2017 94 10 20 2017 Technology and Engineering Nanocomposites Damage tolerance Fatigue Electrospinning info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/8507673/file/8507676 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 3296630 bytes journal version.pdf Daelemans, Lode, Sam van der Heijden, Ives De Baere, Hubert Rahier, Wim Van Paepegem, and Karen De Clerck. 2017. “Improved Fatigue Delamination Behaviour of Composite Laminates with Electrospun Thermoplastic Nanofibrous Interleaves Using the Central Cut-Ply Method.” COMPOSITES PART A-APPLIED SCIENCE AND MANUFACTURING 94: 10–20. doi:10.1016/j.compositesa.2016.12.004.

Although fiber-reinforced polymer composites show many advantages compared to other materials, delamination between reinforcing plies remains a major problem limiting further breakthrough. Traditional solutions that have been proposed to toughen the interlaminar region between reinforcing plies have already reached their limit or have important disadvantages such as a high cost or the need for adapted production processes. Recently, electrospun nanofibers have been suggested as a more viable interlaminar toughening method. Although the expected benefits are numerous, the research on composite laminates enhanced with electrospun nanofibrous veils is still very limited. The work that has been done so far is almost exclusively focused on interlaminar fracture toughness tests with different kinds of nanofibers, where typically a trial and error approach has been used. A thorough understanding of the micromechanical fracture mechanisms and the parameters to obtain toughened composites has not been reported as of yet, but it is crucial to advance the research and design highly damage-resistant composites. This article provides such insight by analyzing the nanofiber toughening effect on three different levels for several nanofiber types. Only by combining the results from different levels, a thorough understanding can be obtained. These levels correspond to the hierarchical nature of a composite: the laminate, the interlaminar region, and the matrix resin. It is found that each level corresponds to certain mechanisms that result in a toughening effect. The bridging of microcracks by electrospun nanofibers is the main toughening mechanism resulting in damage resistance. Nevertheless, the way in which the nanofiber bridging mechanism expresses itself is different for each scale and dependent on parameters linked to a certain scale. The multiscale analysis of the toughening mechanisms reported in this paper is therefore crucial for understanding the behavior of nanofiber toughened composites, and as such allows for designing novel, damage-resistant, nanofiber-toughened materials. journalArticle original public Article A1 published published ugent Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Sam van der Heijden Sam van der Heijden aut author 000070168988 802001291348 972120157894 UGent Ives De Baere Ives De Baere aut author 801001866905 977854465771 0000-0002-6846-0981 TW11 Hubert Rahier Hubert Rahier aut author Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Kirk Schanze Kirk Schanze edt editor Department of Materials Science and Engineering (ceased 1-2-2017) TW10 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department 1944-8252 2016 8 18 111806 11818 2016 Technology and Engineering nanofiber bridging fracture toughness electrospinning nanocomposites veils fiber reinforced polymer DELAMINATION STRENGTH delamination INTERLAMINAR FRACTURE-TOUGHNESS MODE-I CARBON/EPOXY COMPOSITES CURING CHARACTERISTICS POLYMER DIFFUSION PHASE-SEPARATION EPOXY MATRIX NANOCOMPOSITES info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/7202753/file/7202772 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 2217596 bytes ACS_appl_mat_int_Toughening_mechanisms_Daelemans_van_der_Heijden_et_al.pdf http://pubs.acs.org/journal/aamick open fullText http://purl.org/dc/dcmitype/InteractiveResource Daelemans, Lode, Sam van der Heijden, Ives De Baere, Hubert Rahier, Wim Van Paepegem, and Karen De Clerck. 2016. “Damage-Resistant Composites Using Electrospun Nanofibers: A Multiscale Analysis of the Toughening Mechanisms.” Ed by.

Nevertheless, delamination between reinforcing plies and brittle matrix fracture remain the most important failure modes that are encountered in service for laminated composite materials. Although traditional solutions exist to toughen the interlaminar region between reinforcing plies, these systems often have important disadvantages which makes it too difficult to apply them to industrial scale. Recently, electrospun nanofibers have been suggested as an interlaminar toughening method which is much more viable as the electrospinning is relatively straightforward and scalable while the nanofibers do not affect the composite production process. Nevertheless, although the expected benefits are numerous, the research on composite laminates enhanced with electrospun nanofibrous veils is still very limited. A thorough understanding of the micromechanical fracture mechanisms and the parameters to obtain toughened composites have not been determined as of yet, but it is crucial in order to advance the research into these materials. In this presentation we would like to provides such insights by analyzing the nanofiber toughening effect on three different levels simultaneously for several nanofiber types: (i) the nano reinforced epoxy level, (ii) the interlaminar level and (iii) the laminate level. It was found that each level corresponds to certain (micro)mechanisms that result in a toughening effect. The bridging of microcracks by electrospun nanofibers is the main toughening mechanisms present on all levels. Nevertheless, the obtained increase in interlaminar fracture toughness on the interlaminar and laminate level is dependent on many more parameters which have been overlooked until now and are exposed by our multiscale analysis. In this presentation emphasis will be given on the effect of the mechanical properties of the nanofiber and how it influences the fracture toughness of the composites on these different levels. conference public C3 published published ugent Sam van der Heijden Sam van der Heijden aut author 000070168988 802001291348 972120157894 UGent Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Ives De Baere Ives De Baere aut author 801001866905 977854465771 0000-0002-6846-0981 TW11 Hubert Rahier Hubert Rahier aut author Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Dario Pisignano Dario Pisignano edt editor Luana Persano Luana Persano edt editor Andrea Camposeo Andrea Camposeo edt editor Department of Materials Science and Engineering (ceased 1-2-2017) TW10 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department Otranto, Italy 2016-06-28 2016-07-01 Otranto, Italy Universita del Salento 2016 1 1 2016 Technology and Engineering info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/8034167/file/8034173 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 8359 bytes 1108__VanderHeijden_.pdf https://biblio.ugent.be/publication/8034167/file/8034327 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf toc http://purl.org/dc/dcmitype/Text 410553 bytes Electrospin2016_Program_Posters_Final.pdf http://conference.unisalento.it/ocs/index.php/electrospin/electrospin2016 open fullText http://purl.org/dc/dcmitype/InteractiveResource van der Heijden, Sam, Lode Daelemans, Ives De Baere, Hubert Rahier, Wim Van Paepegem, and Karen De Clerck. 2016. “TOWARDS DAMAGE RESISTANT COMPOSITES USING ELECTROSPUN NANOFIBERS: A MULTISCALE ANALYSIS OF THE TOUGHENING MECHANISMS.” In 4th International Conference on Electrospinning, ed by.

Self-healing materials are being developed to extend their lifetime. Today, most self-healing systems are based on the introduction of microcapsules. Although a lot of progress has been made, the effect of introducing such healing feature on the mechanical properties of the neat material is mainly overlooked, with the microcapsules creating potential artefacts in the neat matrix material. The use of a nanovascular network may show a better solution to apply self-healing systems. Therefore in the present paper we created a nanovascular network by pullulan sacrificial electrospun nanofibers, analysed the flexural properties and compared them to those of the neat matrix material as well as reported microcapsule-based materials. A detailed parameter analysis of the electrospinning process allowed for the production of tailored pullulan nanofibers. The introduction of the pullulan nanofibers showed no effect on the strength and modulus of the neat epoxy. On removal of the pullulan, the properties of the resultant nanovascular epoxy matrix system were somewhat reduced relative to the neat epoxy with an effect in proportion to the volume fraction and the diameter of the channels. However very interesting, the decrease of the mechanical properties of the nanovascular epoxy is far lower than on the introduction of microcapsules and opens potentials for a more appropriate introduction of self-healing systems in composite materials. conference public C3 published published ugent Ana Torre Muruzabal Ana Torre Muruzabal aut author 000091854350 091009031436 UGent Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 G Van Assche G Van Assche aut author Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Hubert Rahier Hubert Rahier aut author Dario Pisignano Dario Pisignano edt editor Luana Persano Luana Persano edt editor Andrea Camposeo Andrea Camposeo edt editor Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Otranto, Italy 2016-06-28 2016-07-01 Otranto, Italy Universita del Salento 2016 1 1 2016 Technology and Engineering info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/8035083/file/8035138 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 87232 bytes 1211__Torre-Muruzabal_.pdf https://biblio.ugent.be/publication/8035083/file/8035144 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf toc http://purl.org/dc/dcmitype/Text 410553 bytes Electrospin2016_Program_Posters_Final.pdf http://conference.unisalento.it/ocs/index.php/electrospin/electrospin2016 open fullText http://purl.org/dc/dcmitype/InteractiveResource Torre Muruzabal, Ana, Lode Daelemans, G Van Assche, Karen De Clerck, and Hubert Rahier. 2016. “Electrospinning of Sacrificial Nanofibers for the Creation of a Self-Healing Nanovascular Network and Its Effect on the Properties of an Epoxy Matrix.” In 4th International Conference on Electrospinning, ed by.

This makes them applicable in many fields, including wound management, where nanofibers serve as an optimal support material. In this paper, fast responding and user-friendly biocompatible, halochromic nanofibrous sensors are successfully fabricated by incorporating the halochromic dyes Methyl Red and Rose Bengal inside a chitosan/poly(e-caprolactone) nanofibrous matrix. The commonly applied dye-doping technique frequently suffers from dye-leaching, which not only reduces the sensor's sensitivity over time but can also induce adverse effects. Therefore, in this work, dye-immobilization is accomplished by covalent dye-modification of chitosan before blend electrospinning. It is shown that efficient dye-immobilization with minimal dye-leaching is achieved within the biomedical relevant pH-region, without significantly affecting the halochromic behavior of the dyes. This is in contrast to the commonly applied dye-doping technique and other dye-immobilization strategies stated in literature. Moreover, the nanofibers show high and reproducible pH-sensitivity by providing an instantaneous color change in response to change in pH in aqueous medium and when exposed to acidic or basic gases. The results stated within this work are of particular interest for natural (bio) polymers for which covalent modification combined with electrospinning provides a universal method for versatile dye-functionalization of large area nanofibrous membranes with proper dye-immobilization. journalArticle original public Article A1 published published ugent 4 Ella Schoolaert Ella Schoolaert aut author 000100318410 802002133935 975208259089 0000-0003-4345-8225 UGent Iline Steyaert Iline Steyaert aut author 000060129993 802001072793 979860756278 UGent Gertjan Vancoillie Gertjan Vancoillie aut author 000060487479 802001083911 973415065357 UGent Jozefien Geltmeyer Jozefien Geltmeyer aut author 000070582957 975000449525 0000-0002-1281-2968 Kathleen Lava Kathleen Lava aut author 802001421589 974160946756 UGent Richard Hoogenboom Richard Hoogenboom aut author 802000620432 975196852903 0000-0001-7398-2058 WE07 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Organic and Macromolecular Chemistry WE07 sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department 2050-750X 2016 4 26 4507 4516 2016 Technology and Engineering POLYCAPROLACTONE DESIGN CELLULOSE DERIVATIVES NANOFIBERS AZO-DYES OPTICAL SENSORS NITRAZINE YELLOW ROSE-BENGAL CELLULOSE DERIVATIVES DESIGN IMMOBILIZATION POLYCAPROLACTONE IMMOBILIZATION info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8109195/file/8109230 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 5556473 bytes dye-functionalized_chitosan_Journal_of_Materials_Chemistry_Schoolaert_et_al.pdf https://biblio.ugent.be/publication/8109195/file/8557396 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 861631 bytes Revised manuscript_versie biblio.pdf Schoolaert, Ella, Iline Steyaert, Gertjan Vancoillie, Jozefien Geltmeyer, Kathleen Lava, Richard Hoogenboom, and Karen De Clerck. 2016. “Blend Electrospinning of Dye-Functionalized Chitosan and Poly(ε-Caprolactone) : Towards Biocompatible PH-Sensors.” JOURNAL OF MATERIALS CHEMISTRY B 4 (26): 4507–4516. doi:10.1039/c6tb00639f.

Halochromic dyes show high potential within this field as pH-changes are visualized by a fast and simple change of color.[1] A smart halochromic sensor can be fabricated by incorporating such halochromic dye into a suitable matrix material, resulting in a custom, user-friendly product, providing clear information in a non-destructive way. Polymer nanofibers are a very well suited matrix material since nanofibrous nonwovens are characterized by a high specific surface area, small pore size, high pore volume and high absorbance capacity, making them ideal candidates for advanced, fast-responding sensor applications.[2] Dye-immobilization is, currently, a major challenge in nanofibrous sensor design as dye-doped solvent electrospinning, i.e.the most commonly applied processing technique, suffers from leaching of the dye out of the nanofibrous network.[3] Our research focuses on dye-immobilization through covalent dye-modification, where the polymer backbone is modified with a halochromic dye before the electrospinning process, providing a covalent linkage between the dye and the polymer. This technique is of particular interest for the application of natural (bio)polymers, such as chitosan.[4] The nanofibrous structure is ideally produced via blend electrospinning, which allows for the selection of a suitable carrier polymer that is widely available and well electrospinnable along with an appropriate amount of dye-modified polymer for the specific application. Of course, the question arises, if the modification of the polymer has a significant influence on the electrospinning process and, moreover, if the halochromic properties of the dye are maintained within the nanofibrous network. Within our research, chitosan was successfully modified and blend electrospun for the production of halochromic nanofibers. We found that the covalent modification could both positively as well as negatively affect the electrospinnability of the polymer. Additionally, dye-migration was significantly reduced within the entire pH-range, without majorly affecting the halochromic properties of the dyes. Future work will include the selection of a dye with a suitable pH-range for the intended application, without negatively affecting the electrospinning process. Nevertheless, our research already showed the great potential of the combination of covalent modification with electrospinning, especially for natural (bio)polymers, as it provides a universal method for versatile dye-functionalization of large-area nanofibrous nonwovens. conference poster public C3 published published ugent Ella Schoolaert Ella Schoolaert aut author 000100318410 802002133935 975208259089 0000-0003-4345-8225 UGent Richard Hoogenboom Richard Hoogenboom aut author 802000620432 975196852903 0000-0001-7398-2058 WE07 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Organic and Macromolecular Chemistry WE07 sht department Hasselt, Belgium 2016-05-23 2016-05-24 2016 129 129 2016 Technology and Engineering Nanofibers Electrospinning stimuli-sensitive dyes optical sensor info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/8604752/file/8604754 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 19989635 bytes 1463728915Book-BPG-2016-Web.pdf https://biblio.ugent.be/publication/8604752/file/8604755 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 918843 bytes Poster P087_BPG annual meeting 2016_Ella Schoolaert.pdf Schoolaert, Ella, Richard Hoogenboom, and Karen De Clerck. 2016. “Blend Electrospinning of Dye-Functionalized Chitosan and Polycaprolactoe : Towards Biocompatible PH-Sensors.” In BPG Annual Meeting 2016_Book of Abstracts, 129–129.

By controlling the reaction conditions, the rheological properties of the sol allowed for electrospinning without needing the addition of an organic polymer. This allows the polymer removal step, which is deleterious to the fibers and an economic and ecological inconvenience, to be skipped. The effects on the electrospinning process of the viscosity of the sol, the concentration of ethanol, the degree of crosslinking and the size of the colloidal species were studied in depth with ATR-FTIR, Si-29 NMR, H-1 NMR and DLS. Moreover, to separate the contributions of the different parameters three different set-ups for sol preparation were used. An optimum amount of 9 mol L-1 ethanol for electrospinning was determined. In addition, the optimum degree of crosslinking and size of colloidal particles, approximately 3.5-7 nm, were obtained for stable electrospinning and for producing uniform, beadless nanofibers that were stable in time. The optimum viscosity range is in between 100 and 200 mPa s, which is in line with previous work. Using these optimum conditions, continuous electrospinning was carried out for 3 h, resulting in large flexible silica nanofibrous membranes. journalArticle original public Article A1 published published ugent 5 Jozefien Geltmeyer Jozefien Geltmeyer aut author 000070582957 975000449525 0000-0002-1281-2968 Jonathan De Roo Jonathan De Roo aut author 000070278722 802001023081 975366723747 0000-0002-1264-9312 UGent Freya Van den Broeck Freya Van den Broeck aut author 002005434984 802000856060 978599531865 UGent José Martins José Martins aut author 801000687646 971318312650 0000-0001-7350-2253 WE07 Klaartje De Buysser Klaartje De Buysser aut author 801001571962 978828372447 0000-0001-7462-2484 WE06 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Inorganic and physical chemistry (ceased 1-1-2018) WE06* sht department Department of Organic and Macromolecular Chemistry WE07 sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department 0928-0707 2016 77 2 453 462 2016 Technology and Engineering NMR Sol-gel TEOS Nanofibers GEL PROCESS FIBERS FABRICATION COMPOSITE SPECTROSCOPY SPECTRA SOLVENT Electrospinning info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/6959183/file/6959218 info:eu-repo/semantics/closedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 2000848 bytes 10_1007_s10971-015-3875-1.pdf https://biblio.ugent.be/publication/6959183/file/8516768 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1776921 bytes Geltmeyer_2016_JSGST_77_2_453.pdf https://biblio.ugent.be/publication/6959183/file/8561082 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1386882 bytes 150424 Paper JGeltmeyer.pdf Geltmeyer, Jozefien, Jonathan De Roo, Freya Van den Broeck, José Martins, Klaartje De Buysser, and Karen De Clerck. 2016. “The Influence of Tetraethoxysilane Sol Preparation on the Electrospinning of Silica Nanofibers.” JOURNAL OF SOL-GEL SCIENCE AND TECHNOLOGY 77 (2): 453–462. doi:10.1007/s10971-015-3875-1.

Although fiber reinforced polymer composites show many advantages compared to other materials, delamination between reinforcing plies remains a major problem limiting further breakthrough. Previous work has shown that electrospun nanofibers can significantly improve the interlaminar fracture toughness of fiber reinforced composites thus preventing delaminations. In the present paper, the effect of the morphology of the toughening polymer is analyzed by incorporating different polycaprolactone structures in the interlaminar regions. Both Mode I and Mode II interlaminar facture toughness of composites containing five different electrospun morphologies - nanofibers, microfibers, microspheres, dense films, and PCL spray coated glass fibers - were evaluated. Analyzing the fracture behavior of the PCL toughened laminates ensures a better insight in the micro mechanical fracture mechanisms behind the observed interlaminar fracture toughness and results in guidelines on the optimal interleave morphology. The results clearly demonstrate the distribution of PCL in the interlayer has a large effect on the crack path of the delamination and the resulting interlaminar fracture toughness. In order to improve the interlaminar fracture toughness in both Mode I as well as Mode II without adverse effects, porous PCL structures such as PCL nanofibers, microfibers, and micro spheres are much more suitable than non-porous structures such as PCL films or spray-coated glass fibers. Among the porous structures, the nanofibers had an overall better performance with an increase in Mode I and Mode II interlaminar fracture toughness of about 60% and 80% respectively.

Recently, these dye molecules were modified to form a covalent bond with the polymer host. This had a large influence on the pH-sensitive properties, in particular on the acidity constant (pKa). Obtaining molecular control over the factors that influence the pK(a) value is mandatory for the future intelligent design of sensor materials. Herein, we show that advanced molecular dynamics (MD) methods have reached the level at which the pK(a) values of large solvated dye molecules can be predicted with high accuracy. Two MD methods were used in this work: steered or restrained MD and the insertion/deletion scheme. Both were first calibrated on a set of phenol derivatives and afterwards applied to the dye molecule bromothymol blue. Excellent agreement with experimental values was obtained, which opens perspectives for using these methods for designing dye molecules. journalArticle original public Article A1 published published ugent 5 Thierry De Meyer Thierry De Meyer aut author 000060024711 802001054912 976159278112 UGent Bernd Ensing Bernd Ensing aut author Sven Rogge Sven Rogge aut author 802001863547 974472205006 0000-0003-4493-5708 TW17 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Evert Jan Meijer Evert Jan Meijer aut author Veronique Van Speybroeck Veronique Van Speybroeck aut author 801001153549 919016668139 976495757166 0000-0003-2206-178X TW17 WE05 Department of Applied physics TW17 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Department of Physics and astronomy WE05 sht department 1439-4235 1439-7641 2016 17 21 3447 3459 2016 Technology and Engineering Chemistry Physics and Astronomy Physical and Theoretical Chemistry Atomic and Molecular Physics and Optics DENSITY-FUNCTIONAL THEORY PH-SENSITIVE FUNCTION TEXTILE MATERIALS AQUEOUS-SOLUTION LIQUID WATER FREE-ENERGY PKA VALUES HALOCHROMIC PROPERTIES SULFONPHTHALEINE DYES NITRAZINE YELLOW acidity dyes/pigments free energy methods molecular dynamics steered molecular dynamics info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8501546/file/8501549 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1813834 bytes De-Meyer_et_al-2016-ChemPhysChem.pdf De Meyer, Thierry, Bernd Ensing, Sven Rogge, Karen De Clerck, Evert Jan Meijer, and Veronique Van Speybroeck. 2016. “Acidity Constant (PKa) Calculation of Large Solvated Dye Molecules : Evaluation of Two Advanced Molecular Dynamics Methods.” CHEMPHYSCHEM 17 (21): 3447–3459. doi:10.1002/cphc.201600734.

Inappropriate storage, however, could alter their performance, e.g. regarding water filtration. This shows the need for investigating this effect in more detail so as to offer a solution for long-term behaviour and stability. In this study, polyamide nanofibre membranes were treated under different conditions, simulating the diverse storage conditions and to simulate their use in water filtration systems. Under all these different settings, nanofibre properties (scanning electron microscope pictures, dimensional changes, tensile strength) and water filtration performance (clean water permeability (CWP), bacterial removal) were investigated. The results demonstrate that, as soon as the dimensional change of a membrane is >2%, the CWP, tensile strength and bacterial removal significantly decrease. These dimensional changes occurred when the membrane became dry after it had been in contact with water. As such, it is important to keep the membrane either in dry or in wet conditions to store its unique properties. When heat-treated, the membrane had a higher tensile strength and kept its morphology and characteristics better during storage. journalArticle original public Article A1 published published ugent 14 Nele Daels Nele Daels aut author 002003290072 802000583955 977784615061 UGent Lies Harinck Lies Harinck aut author 802001417650 972688684190 LA24 Annelies Goethals Annelies Goethals aut author 002004215111 802000839185 971337473685 UGent Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Stijn Van Hulle Stijn Van Hulle aut author 801001539933 919019834884 971483871644 0000-0001-5773-7773 LA24 Department of Mathematical Modelling, Statistics and Bio-informatics (ceased 1-1-2018) LA10 sht department Department of Sustainable Organic Chemistry and Technology (ceased 1-1-2018) LA11 sht department Department of Industrial Biological Sciences (ceased 1-1-2018) LA16 sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department 0273-1223 2016 73 8 1920 1926 2016 Technology and Engineering electrospinning membrane stability microfiltration nanofibres 3D FIBER ORIENTATION OPTIMIZATION PERFORMANCE PARAMETERS MORPHOLOGY EFFICIENCY NETWORKS HUMIDITY FILTERS MBR info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/7197165/file/7197168 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 450049 bytes Daels_et_al.__2016.pdf Daels, Nele, Lies Harinck, Annelies Goethals, Karen De Clerck, and Stijn Van Hulle. 2016. “Structure Changes and Water Filtration Properties of Electrospun Polyamide Nanofibre Membranes.” WATER SCIENCE AND TECHNOLOGY 73 (8): 1920–1926. doi:10.2166/wst.2016.033.

Interleaving composites with electrospun nanofibrous veils is proving to be a viable technique in order to increase the delamination resistance. The veils can easily be placed in the resin rich interlayers prior to production and do not require a dispersion in the matrix resin such as traditional particle toughening techniques. Furthermore, they are easily produced by electrospinning. Although there are many expected obvious benefits, the research on composites toughened with electrospun nanofibres is still very limited. We will give thorough insight into the toughening micromechanisms that are present in laminates interleaved with nanofibrous veils. The bridging of microcracks by nanofibres is shown to be the main mechanism resulting in an increased interlaminar fracture toughness. Upon crack extension, nanofibres will bridge the newly formed crack surfaces and take up energy by straining, yielding and fracture. Several parameters are identified which influence this nanofibre bridging, and thus the observed interlaminar fracture toughness. This allows us to accurately determine the crucial parameters and toughening mechanisms which is necessary for the design of advanced damage resistance composite materials. conference public C1 published published ugent Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Sam van der Heijden Sam van der Heijden aut author 000070168988 802001291348 972120157894 UGent Ives De Baere Ives De Baere aut author 801001866905 977854465771 0000-0002-6846-0981 TW11 Hubert Rahier Hubert Rahier aut author Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials Science and Engineering (ceased 1-2-2017) TW10 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department Munich, Germany 2016-06-26 2016-06-30 978-3-00-053387-7 European Society for Composite Materials (ESCM) 2016 1 8 2016 Technology and Engineering Nanofibres Electrospinning Fracture toughness Damage resistance Delaminaion info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/8050496/file/8050508 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 497936 bytes full_paper.pdf Daelemans, Lode, Sam van der Heijden, Ives De Baere, Hubert Rahier, Wim Van Paepegem, and Karen De Clerck. 2016. “Increasing the Damage Resistance of Composites by Interleaving Them with Electrospun Nanofibrous Veils.” In 17th European Conference on Composite Materials, 1–8.

Self-healing materials are being developed to extend their lifetime. Today, most self-healing systems are based on the introduction of microcapsules. Although a lot of progress has been made, the effect of introducing such healing feature on the mechanical properties of the neat material is mainly overlooked, with the microcapsules creating potential artefacts in the neat matrix material. The use of a nanovascular network may show a better solution to apply self-healing systems. Therefore in the present paper we created a nanovascular network by pullulan sacrificial electrospun nanofibers, analysed the flexural properties and compared them to those of the neat matrix material as well as reported microcapsule-based materials. A detailed parameter analysis of the electrospinning process allowed for the production of tailored pullulan nanofibers. The introduction of the pullulan nanofibers showed no effect on the strength and modulus of the neat epoxy. On removal of the pullulan, the properties of the resultant nanovascular epoxy matrix system were somewhat reduced relative to the neat epoxy with an effect in proportion to the volume fraction and the diameter of the channels. However very interesting, the decrease of the mechanical properties of the nanovascular epoxy is far lower than on the introduction of microcapsules and opens potentials for a more appropriate introduction of self-healing systems in composite materials. conference public C3 published published ugent Ana Torre Muruzabal Ana Torre Muruzabal aut author 000091854350 091009031436 UGent Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Guy Van Assche Guy Van Assche aut author Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Hubert Rahier Hubert Rahier aut author Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Otranto, Italy 2016-09-05 2016-09-08 Otranto, Italy 2016 1 1 2016 Technology and Engineering info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/8127576/file/8127582 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 881957 bytes Electrospin_2016_Torre-Muruzabal.pdf Torre Muruzabal, Ana, Lode Daelemans, Guy Van Assche, Karen De Clerck, and Hubert Rahier. 2016. “Electrospinning of Sacrificial Nanofibers for the Creation of a Self-Healing Nanovascular Network and Its Effect on the Properties of an Epoxy Matrix.” In 4th International Conference on Electrospinning, 1–1.

Until now sol-gel-based colorimetric sensors are usually nonflexible bulk glass or thin-film sensors. Large-area, flexible sensors usable in strong acidic environments are not available. Therefore, in this study organically modified silicon oxide nanofibrous membranes are produced by combining electrospinning and sol-gel technology. Two pH-indicator dyes are immobilized in the nanofibrous membranes: methyl yellow via doping, methyl red via both doping, and covalent bonding. This resulted in sensor materials with a fast response time and high sensitivity for pH-change in water. The covalent bond between dye and the sol-gel network showed to be essential to obtain a reusable pH-sensor in aqueous environment. Also a high sensitivity is obtained for sensing of HCl and NH3 vapors, including a memory function allowing visual read-out up to 20 min after exposure. These fast and reversible, large-area flexible nanofibrous colorimetric sensors are highly interesting for use in multiple applications such as protective clothing and equipment. Moreover, the sensitivity to biogenic amines is demonstrated, offering potential for control and monitoring of food quality. journalArticle original public Article A1 published published ugent 1 Jozefien Geltmeyer Jozefien Geltmeyer aut author 000070582957 975000449525 0000-0002-1281-2968 Gertjan Vancoillie Gertjan Vancoillie aut author 000060487479 802001083911 973415065357 UGent Iline Steyaert Iline Steyaert aut author 000060129993 802001072793 979860756278 UGent Bet Breyne Bet Breyne aut author 000100486946 Gabriella Cousins Gabriella Cousins aut author 000141364766 Kathleen Lava Kathleen Lava aut author 802001421589 974160946756 UGent Richard Hoogenboom Richard Hoogenboom aut author 802000620432 975196852903 0000-0001-7398-2058 WE07 Klaartje De Buysser Klaartje De Buysser aut author 801001571962 978828372447 0000-0001-7462-2484 WE06 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Organic and Macromolecular Chemistry WE07 sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Department of Inorganic and physical chemistry (ceased 1-1-2018) WE06* sht department 1616-301X 2016 26 33 5987 5996 2016 Chemistry ACID-BASE EQUILIBRIA ELECTROSPUN NANOFIBERS SOL-GEL MATRIX PH-INDICATOR METHYL RED TEXTILE MATERIALS NITRAZINE YELLOW OPTICAL SENSORS GAS NANOPARTICLES info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8166617/file/8166629 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1608188 bytes Geltmeyer_et_al-2016-Advanced_Functional_Materials.pdf https://biblio.ugent.be/publication/8166617/file/8561081 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 1900132 bytes Manuscript JGeltmeyer_revision data Methyl Yellow_2-kdc.pdf Geltmeyer, Jozefien, Gertjan Vancoillie, Iline Steyaert, Bet Breyne, Gabriella Cousins, Kathleen Lava, Richard Hoogenboom, Klaartje De Buysser, and Karen De Clerck. 2016. “Dye Modification of Nanofibrous Silicon Oxide Membranes for Colorimetric HCl and NH3 Sensing.” ADVANCED FUNCTIONAL MATERIALS 26 (33): 5987–5996. doi:10.1002/adfm.201602351.

This paper investigates if polycaprolactone (PCL) nanofibre nonwovens can increase the interlaminar fracture toughness of resin transfer moulded glass fibre/epoxy laminates, without causing problems during impregnation and without negatively affecting other (mechanical) properties. The mode I fracture toughness was shown to be dependent on both the nanofibre content as well as on how the nanofibres were introduced into the laminates. Almost 100% improvement in fracture toughness could be achieved by electrospinning the PCL nanofibres on both sides of the glass fibre mats prior to impregnation. This led to a mode I fracture toughness of over 1200 J/m2. It could be concluded that even state of the art infusion resins with a high intrinsic fracture toughness can benefit significantly from nanofibre toughening. conference public C1 published published ugent Sam van der Heijden Sam van der Heijden aut author 000070168988 802001291348 972120157894 UGent Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Ives De Baere Ives De Baere aut author 801001866905 977854465771 0000-0002-6846-0981 TW11 Huber Rahier Huber Rahier aut author Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials Science and Engineering (ceased 1-2-2017) TW10 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department Copenhagen, Denmark 2015-07-19 2015-07-24 2015 2015 Technology and Engineering info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/8037278/file/8037313 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/vnd.openxmlformats-officedocument.wordprocessingml.document fullText http://purl.org/dc/dcmitype/Text 237878 bytes versie_iccm.docx http://iccm20.org/fullpapers/file?f=dRpeDO2RaA open fullText http://purl.org/dc/dcmitype/InteractiveResource van der Heijden, Sam, Lode Daelemans, Ives De Baere, Huber Rahier, Wim Van Paepegem, and Karen De Clerck. 2015. “Interlaminar Toughening of Resin Transfer Moulded Glass Fibre Epoxy Laminates by Polycaprolactone Electrospun Nanofibres.” In 20th International Conference on Composite Material.

Most of these sensors rely on indicator compounds showing a change in optical absorbance (colour) or fluorescence under the influence of a certain parameter. Halochromic dyes, for instance, change colour with pH. Since the use of nanofibres improves sensor sensitivity and response time due to their large surface area to volume ratio, the incorporation of indicator compounds into nanofibres is one of the current challenges in sensor design. This chapter discusses the production of colorimetric and fluorescent nanofibrous membranes for visual and optical monitoring (Sects. 7.3 and 7.4), supplemented by some fundamental information on those sensing systems (Sect. 7.2) and some interesting applications (Sect. 7.5). conference proceedingsPaper public Proceedings Paper P1 published published ugent Iline Steyaert Iline Steyaert aut author 000060129993 802001072793 979860756278 UGent Hubert Rahier Hubert Rahier aut author Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Antonella Macagnano Antonella Macagnano edt editor Emiliano Zampetti Emiliano Zampetti edt editor Erich Kny Erich Kny edt editor Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Natl ResCouncil, Inst Atmospher Pollut Res, Rome, ITALY 2014-04-29 2014-04-30 1434-4904 9783319144061 Springer 2015 157 177 2015 Technology and Engineering DYE NITRAZINE YELLOW VOLATILE ORGANIC-COMPOUNDS CONJUGATED POLYMER ELECTROSPUN NANOFIBERS CHEMICAL SENSORS AZO-DYES PH SENSOR FLUORESCENCE BIOSENSORS MEMBRANES info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/5967681/file/5967800 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 16760438 bytes boekhfdst.pdf http://www.springer.com/it/book/9783319144054 open fullText http://purl.org/dc/dcmitype/InteractiveResource Steyaert, Iline, Hubert Rahier, and Karen De Clerck. 2015. “Nanofibre-Based Sensors for Visual and Optical Monitoring.” In Nanoscience and Technology, ed by.

However, it is often reported that the presence of these polyesters has a detrimental effect on the mechanical properties of the resulting composite laminates. This study shows that interlaminar toughness can be increased without negatively affecting other properties by a applying a bisphenol A based polyester binder. Both polyester modified epoxy resin as well as polyester modified glass/epoxy laminates are studied. It is shown that the presence of the polyester has a profound effect on the curing characteristics and glass transition temperature of the epoxy resin. Furthermore, fracture toughness experiments (Single Edge Notch Bending) show that there is an optimum polyester concentration which leads to a toughened epoxy matrix. Composite laminates are produced from binder coated glass fibre plies with VARTM. Double Cantilever Beam fracture experiments show that the polyester binder increases the Mode I interlaminar toughness by 60 %. Three point bending experiments show that the flexural properties were not negatively affected by the presence of the polyester in the interlaminar region between plies. conference proceedingsPaper public Proceedings Paper P1 published published ugent Lode Daelemans Lode Daelemans aut author 802001635191 971650880382 0000-0001-6214-3785 TW11 Sam van der Heijden Sam van der Heijden aut author 000070168988 802001291348 972120157894 UGent Ives De Baere Ives De Baere aut author 801001866905 977854465771 0000-0002-6846-0981 TW11 Hubert Rahier Hubert Rahier aut author Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials Science and Engineering (ceased 1-2-2017) TW10 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department Copenhagen, Denmark 2015-07-19 2015-07-24 2015 2015 Technology and Engineering Double cantilever beam Fracture toughness Binder/tackifier Vacuum assisted resin transfer moulding info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/6976872/file/6976874 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 665692 bytes USING_A_POLYESTER_BINDER_FOR_THE_INTERLAMINAR_TOUGHENING_OF_GLASS.pdf Daelemans, Lode, Sam van der Heijden, Ives De Baere, Hubert Rahier, Wim Van Paepegem, and Karen De Clerck. 2015. “Using a Polyester Binder for the Interlaminar Toughening of Glass/Epoxy Composite Laminates.” In 20TH INTERNATIONAL CONFERENCE ON COMPOSITE MATERIALS.

Unfortunately, conventional water treatment processes are not able to remove these micropollutants. As such, advanced treatment methods are required to meet both current and anticipated maximally allowed concentrations. Plasma discharge in contact with water is a promising new technology, since it produces a wide spectrum of oxidizing species. In this study, a new type of reactor is tested, in which decomposition by atmospheric pulsed direct barrier discharge (pDBD) plasma is combined with micropollutant adsorption on a nanofiber polyamide membrane. Atrazine is chosen as model micropollutant with an initial concentration of 30 mu g/L. While the H2O2 and O-3 production in the reactor is not influenced by the presence of the membrane, there is a significant increase in atrazine decomposition when the membrane is added. With membrane, 85% atrazine removal can be obtained in comparison to only 61% removal without membrane, at the same experimental parameters. The by-products of atrazine decomposition identified by HPLC-MS are deethylatrazine and ammelide. Formation of these by-products is more pronounced when the membrane is added. These results indicate the synergetic effect of plasma discharge and pollutant adsorption, which is attractive for future applications of water treatment. (C) 2014 Elsevier Ltd. All rights reserved.

Dark brown and brown fibers show a higher sorption capacity compared to beige and white fibers. The differences in sorption capacity are found to be related to the maturity and crystallinity index of the fibers. All fibers exhibited sorption hysteresis to varying degrees throughout the full relative humidity range. The variations in hysteresis behavior are mainly attributed to the differences in crystallinity index of the fibers. In addition the monolayer and polylayer moisture content is analyzed using the Hailwood Horrobin model. Monolayer sorption is most closely related to the crystallinity index and, to a lower extent, maturity of the fibers. For beige and white fibers monolayer sorption remains almost constant, whereas for darker fibers it shows a substantial increase with increasing color difference. In contrast, polylayer sorption shows a general increasing trend over the whole studied color spectrum. Also a noticeable relationship was found between the total hysteresis and the monolayer sorption. Yet such relation was less evident for polylayer sorption. This study contributes to the better understanding of the dynamic moisture sorption behavior of white and naturally colored cotton fibers. This improved understanding is important for optimal application of naturally colored cotton fibers in novel materials. journalArticle original public Article A1 published published ugent 1 Özgür Ceylan Özgür Ceylan aut author 002005040722 802000481295 972618734561 UGent Florence Goubet Florence Goubet aut author Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department 0969-0239 2014 21 3 1149 1161 2014 Technology and Engineering NATURALLY COLORED COTTON WATER-VAPOR SORPTION ADSORPTION-ISOTHERMS ORGANIC-MATTER CELLULOSE MATURITY KINETICS MODEL WOOD HYSTERESIS Moisture sorption Naturally colored cotton Dynamic vapor sorption Hailwood and Horrobin model info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/4420867/file/4420907 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 2456853 bytes Dynamic_moisture_sorption_behavior_of_cotton_fiberswith_natural_brown_pigments_Ceylan_Goubet_De_Clerck_online_version.pdf http://www.researchgate.net/publication/260478924_Dynamic_moisture_sorption_behavior_of_cotton_fibers_with_natural_brown_pigments open fullText http://purl.org/dc/dcmitype/InteractiveResource Ceylan, Özgür, Florence Goubet, and Karen De Clerck. 2014. “Dynamic Moisture Sorption Behavior of Cotton Fibers with Natural Brown Pigments.” CELLULOSE 21 (3): 1149–1161. doi:10.1007/s10570-014-0206-6.

The melting behaviour of several polyamide (PA) types was researched using a fast-scanning calorimeter (RHC, T A Instruments) capable of controlled heating rates above 1000 K min-1. Past heating suppresses kinetic processes such as cold crystallization, crystal reorganization and crystalline perfectioning, which can be necessary for a correct-analysis of crystal structures, especially in oriented polymorphous structures such as PA nanofibres. For PA69, for instance, analysis at higher rates reveals that nanofibres have a much more stable crystal structure than bulk material (only 15% of low-melting phase vs. 71 % in bulk). This difference cannot be seen at 20 K min-1 since this crystal phase recrystallizes during heating, indicating the importance of a higher rate. However, high heating rates may result in thermal lag and a reduced resolution. Our results indicate that this effect becomes significant for all samples at rates above 500 K min-1 due to the high porosity of nanofibrous sample (-90%) and thus low thermal conductivity.

Boron trifluoride diethyl etherate (BF3OEt2) in a various percentage range (1-10%, w/w GPTMS) has been used to catalyze the epoxide ring opening. In order to optimize the system, an FTIR study has been developed and kinetic data were obtained for the epoxy ring opening process. A linear correlation between the obtained kinetic rates and BF3percentage was observed. By nuclear magnetic resonance (NMR) analysis in solution the real structure of NY, derived from an attack of diazonium salt to parahydroxyl position, was confirmed and the final product of the reaction between NY and GPTMS was characterized. Finally, the different amounts of catalyst were found to affect the coatings wash fastness and the halochromic response of the cellulose-based sensors. (C) 2014 Elsevier B. V. All rights reserved.

This paper investigates if polycaprolactone (PCL) nanofibre nonwovens can increase the interlaminar fracture toughness of resin transfer moulded glass fibre/epoxy laminates, without causing problems during impregnation and without negatively affecting other (mechanical) properties. The mode I fracture toughness was shown to be dependent on both the nanofibre content as well as on how the nanofibres were introduced into the laminates. Almost 100% improvement in fracture toughness could be achieved by electrospinning the PCL nanofibres on both sides of the glass fibre mats prior to impregnation. This led to a model fracture toughness of over 1200 J/m(2). Tensile and dynamic mechanical properties of the toughened laminates were not affected by the PCL nanofibres. It could be concluded that even state of the art infusion resins with a high intrinsic fracture toughness can benefit significantly from nanofibre toughening. (C) 2014 Elsevier Ltd.

Modulated temperature differential scanning calorimetry measurements show that the initial reaction rate follows a linearly increasing trend as a function of the moisture content present in the nanofibrous structures. Compared to PA 6 microfibrous structures, incorporating PA 6 nanofibrous structures exposed to the same humidity resulted in a higher initial reaction rate, which is in agreement with the higher water absorption of the nanofibrous structure, measured with differential vapour sorption. Overall, the nanofibres themselves affect the curing characteristics, and the moisture present in the structures enhances this effect. (C) 2014 Elsevier Ltd. All rights reserved.

In this paper, we present a combined experimental and theoretical study to elucidate the halochromic behaviour of a large set of sulfonphthaleine compounds. Starting from an experimental analysis consisting of UV-Vis spectroscopy, the pH region and the absorption wavelengths related to the colour shift are obtained and pK(a) values are derived. The effect of the substituents on the pH region can be traced back to their electron donating/withdrawing properties. Time-Dependent Density Functional Theory (TD-DFT) is able to adequately produce the trend in experimental wavelengths. Proton affinities are used to assess the effect of substituents on the pH region.

In this paper, we present a combined experimental and theoretical study to elucidate the halochromic behaviour of a large set of sulfonphthaleine compounds. Starting from an experimental analysis consisting of UV-Vis spectroscopy, the pH region and the absorption wavelengths related to the colour shift are obtained and pK(a) values are derived. The effect of the substituents on the pH region can be traced back to their electron donating/withdrawing properties. Time-Dependent Density Functional Theory (TD-DFT) is able to adequately produce the trend in experimental wavelengths. Proton affinities are used to assess the effect of substituents on the pH region. The combination of theory and experiment is able to give a better understanding of the pH sensitivity; the methodology in this work will be useful in future dye design and is applicable to other dye classes as well.

Previous studies have shown that nanofiber membranes have high clean water permeability. The pathogen removal efficiency can be improved by functionalization with (organic) biocides. However, these membranes, like other membranes, are vulnerable to fouling which reduces the filtration efficiency. Therefore the present article investigates the potential of zinc phthalocyanines, which can produce singlet oxygen in the presence of visible light, as a functionalizing agent. The polyamide nanofiber membranes were functionalized with phthalocyanines using both a pre-functionalizing and post-functionalizing method. Only the post-functionalization method shows to result in nanofiber membranes capable of producing singlet oxygen. After 30 min 45% of 1,2-diphenylisobenzofuran (DPBF), used as an oxygen quencher, was removed by reaction with singlet oxygen. This resulted in a removal rate of 0.33 mol DBPF mol(-1)Zn min(-1). During short term leaching tests, phthalocyanines could not be detected. (c) 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 40486.

The method implies sampling of the ground state potential energy surface. Subsequently, the power spectrum of the velocities is compared with the power spectrum of the excitation energy computed using time-dependent density functional theory. Peaks in both spectra are compared, and motions exhibiting a linear or quadratic behavior can be distinguished. The quadratically active motions are mainly responsible for the changes in the excitation energy and hence cause shifts between the dynamic and static values of the spectral property. Moreover, information about the potential energy surface of various excited states can be obtained. The procedure is illustrated with three case studies. The first electronic excitation is explored in detail and dominant vibrational motions responsible for changes in the excitation energy are identified for ethylene, biphenyl, and hexamethylbenzene. The proposed method is also extended to other low-energy excitations. Finally, the vibrational fingerprint of the excitation energy of a more complex molecule, in particular the azo dye ethyl orange in a water environment, is analyzed. (C) 2014 AIP Publishing LLC.

However, this knowledge is necessary for upscaling the process. In this study, the optimum viscosity to electrospin in a stable manner is determined and the preparation procedure to obtain this viscosity is evaluated. A narrow viscosity region in which electrospinning is stable could be determined, moreover this region corresponded with nanofibres having the smallest mean diameter. Uniform nanofibres could be obtained with freshly prepared sols and diluted sols, however electrospinning of the fresh sols was more stable. These results demonstrate the feasibility of upscaling the electrospinning of silica nanofibres, since they are electrospinnable in a stable, reproducible manner. conference public C1 published published ugent Jozefien Geltmeyer Jozefien Geltmeyer aut author 000070582957 975000449525 0000-0002-1281-2968 Lien Van der Schueren Lien Van der Schueren aut author 002002166892 802000424715 UGent Klaartje De Buysser Klaartje De Buysser aut author 801001571962 978828372447 0000-0001-7462-2484 WE06 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Chokri Cherif Chokri Cherif edt editor Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Dresden, Germany 2013-05-22 2013-05-24 9783867803434 Dresden, Germany Autex 2013 1 4 2013 Technology and Engineering electrospinning silica sol-gel tetraethyl orthosilicate info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/3228837/file/3228841 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 803213 bytes Autex_2013_JGeltmeyer_Stable_electrospinning.pdf Geltmeyer, Jozefien, Lien Van der Schueren, Klaartje De Buysser, and Karen De Clerck. 2013. “Stable Electrospinning of Silica Nanofibres: Viscosity Study.” In 13th Autex World Textile Conference, Proceedings, ed by.

Even though it is well know that the curing cycle affects the final properties of the composites, up till today the effect of these nanofibrous structures on the curing characteristics of epoxies is not studied in detail. Therefore the influence of nanofibres of different polyamide types (PA 6, PA 6.6, PA 6.9 and PA 4.6) and of polyvinyl alcohol (PVAL) on the curing reaction of a diglycidyl ether of bisphenol A (DGEBA)-methylenedianiline (MDA) system was investigated, using non-isothermal and quasi-isothermal (modulated temperature) differential scanning calorimetry ((MT)DSC) measurements. The effect of the nanofibre fraction and polyamide type is examined, and a comparison with conventional PA 6 fibres is made. For polyamide nanofibres, the accelerating effect seems to result mainly from water present in the nano- and microfibers. PVAL nanofibres accelerated the curing more strongly than the PA nanofibres, though their moisture content was lower, indicating a catalytic effect of the surface hydroxyls. (C) 2013 Elsevier Ltd.

Since it is difficult to obtain a homogeneous dispersion of these nanoparticles, the mechanical improvement of the composites is very moderate. Thermoplastic nanofibrous structures can overcome this issue. Therefore, this paper investigated the effect of electrospun polyamide 6 nanofibrous structures on the mechanical properties of a glass fiber/epoxy composite. The nanofibers are incorporated in the glass fiber/epoxy composite as stand-alone interlayered structures and directly spun on the glass fiber reinforcement. Both incorporation procedures have no negative effect on the impregnation of the epoxy. Incorporation of nanofibers increases the stress at failure in the 0°-direction, the best results are obtained when the nanofibers are directly electrospun on the glass fibers. Optical microscopic images also demonstrate that nanofibers prevent delamination when a 90° crack reaches a neighbourly 0° ply. When the composites are loaded under 45°, it is proven that for an identical stress, the glass fiber composite with deposited nanofibers has less cracks than when interlayered nanofibrous structures are incorporated. conference public C1 published published ugent Ives De Baere Ives De Baere aut author 801001866905 977854465771 0000-0002-6846-0981 TW11 Bert De Schoenmaker Bert De Schoenmaker aut author 002003264107 802000214244 978815731125 UGent Sam van der Heijden Sam van der Heijden aut author 000070168988 802001291348 972120157894 UGent Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Larissa Gorbatikh Larissa Gorbatikh edt editor Department of Materials Science and Engineering (ceased 1-2-2017) TW10 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department Leuven, Belgium 2013-09-16 2013-09-20 Leuven, Belgium 2013 2013 Technology and Engineering info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/4142174/file/4142175 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 746492 bytes CWL_full_paper_IvesDEBAERE.pdf De Baere, Ives, Bert De Schoenmaker, Sam van der Heijden, Wim Van Paepegem, and Karen De Clerck. 2013. “Modifying the Crack Growth in a Glass Fiber Reinforced Epoxy by Adding Polyamide 6 Nanofibers.” In CompositesWeek@Leuven, ed by.

The effect of the test parameters on the thermal degradation of raw cotton fibers is determined. Focus is given to the influence of water immersion on the thermal behavior of cotton fibers. For less mature fibers a clear difference is noted between the degradation profiles of the water-immersed and untreated samples. On the contrary, only a small change is noted on the degradation profile for more mature fibers after water immersion. The maturity and variations in water-soluble content of the fiber are found to be important factors influencing the thermal behavior of raw cotton fibers. Inductively coupled plasma atomic emission spectrometry (ICP-AES) is used to underpin the effect of water immersion on cotton fibers.

To produce silica nanofibres most of the time organic solutions are applied containing a carrying polymer, which is afterwards removed by a thermal treatment to form pure ceramic nanofibres. Although electrospinning of the pure silica precursors without carrying polymer is preferred, the parameters influencing the stability of the electrospinning process are however largely unknown. In addition, this knowledge is essential for potential upscaling of the process. In this study, the optimum viscosity to electrospin in a stable manner is determined and the way to obtain this viscosity is evaluated. Sols with a viscosity between 120 and 200 mPa.s could be electrospun in a stable way, resulting in uniform and beadless nanofibres. Furthermore, this viscosity region corresponded with nanofibres having the lowest mean nanofibre diameters. Electrospinning with diluted sols was possible as well, but electrospinning of the fresh sols was more stable. These results illustrate the importance of the viscosity and degree of crosslinking of the sol for the stable electrospinning of silica nanofibres and demonstrate that upscaling of the electrospinning process of silica nanofibres is feasible journalArticle original public Article A1 published published ugent 5 Jozefien Geltmeyer Jozefien Geltmeyer aut author 000070582957 975000449525 0000-0002-1281-2968 Lien Van der Schueren Lien Van der Schueren aut author 002002166892 802000424715 UGent Frederik Goethals Frederik Goethals aut author 002002096467 802000157155 UGent Klaartje De Buysser Klaartje De Buysser aut author 801001571962 978828372447 0000-0001-7462-2484 WE06 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Inorganic and physical chemistry (ceased 1-1-2018) WE06* sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department 0928-0707 2013 67 1 188 195 2013 Technology and Engineering FIBERS COMPOSITE GEL PROCESS GLASS NANOFIBERS Tetraethyl orthosilicate Silica Stability Electrospinning Sol-gel MORPHOLOGY DIAMETER RESINS info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/3223956/file/3223970 info:eu-repo/semantics/closedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 346503 bytes Optimum_sol_viscosity_for_stable_electrospinning_of_silica_nanofibres_J_Geltmeyer_et_al.pdf https://biblio.ugent.be/publication/3223956/file/4087911 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 714780 bytes 10.1007_2Fs10971-013-3066-x.pdf https://biblio.ugent.be/publication/3223956/file/8561080 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 707610 bytes Revised Stable electrospinning silica nanofibres_1.pdf Geltmeyer, Jozefien, Lien Van der Schueren, Frederik Goethals, Klaartje De Buysser, and Karen De Clerck. 2013. “Optimum Sol Viscosity for Stable Electrospinning of Silica Nanofibres.” JOURNAL OF SOL-GEL SCIENCE AND TECHNOLOGY 67 (1): 188–195. doi:10.1007/s10971-013-3066-x.

These chromic textiles can be used as flexible sensors for various applications. The aim of the current research is to develop textile pH-sensors through the application of pH-sensitive dyes on various textile materials using different techniques. The results of our study show that halochromic dyes can be incorporated into conventional textiles by a conventional dyeing technique. Also coating the fabrics with a sol-gel layer layer containing the halochromic dye proved to be successful. The majority of these developed materials showed a clearly visible color change with a pH-variation. The response of the sensors was dependent on the density of the fabric but was generally relatively fast, especially for the sol-gel treated fabrics. The halochromic coloration of nanofibres was realized by directly adding the dyes during the fiber formation, which was shown to be highly effective. Again, a clear halochromic shift was observed. The response of these sensors was fast thanks to the high porosity of nanofibrous non-wovens. Yet, it should be kept in mind that the halochromic behavior of the dyes in the textile matrix altered compared to their behavior in solution which is most likely attributed to dye-fiber interactions. Generally we can conclude that various coloration techniques showed to be effective for the development of innovative textile pH-sensors. conference proceedingsPaper public Proceedings Paper P1 published published ugent Lien Van der Schueren Lien Van der Schueren aut author 002002166892 802000424715 UGent Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 P Vincenzini P Vincenzini edt editor C Carfagna C Carfagna edt editor Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Montecatini Terme, Italy 2012-06-10 2012-06-14 1662-0356 9783908158660 Stafa-Zürich, Switzerland Trans Tech Publications 2013 80 47 52 2013 Technology and Engineering dyeing chromism sol-gel electrospinning pH sensor info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/3118695/file/3118697 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 351952 bytes AST_80_471.pdf Van der Schueren, Lien, and Karen De Clerck. 2013. “Halochromic Textile Materials as Innovative PH-Sensors.” In Advances in Science and Technology, ed by.

A case study of PA6, PA46 and PA69 nanofibres is performed using a Rapid Heat-Cool DSC (RHC), a fast-scanning calorimeter capable of controlled heating rates above 1000 K min(-1). Thermal lag becomes significant at scan rates above 500 K min(-1) and the ideal scan rate for analysis of the crystal structure depends on the PA type. Measurements at the most suitable heating rate indicate that the thermal stability of the crystals is higher for nanofibres compared to bulk material. Additionally, more stable crystals are favoured in finer nanofibres. This is especially the case for PA6 nanofibres, having an increasing fraction of stable cc-crystal phase with decreasing fibre diameter, as shown by both thermal analysis and X-ray diffraction.

A homogeneous dispersion of these nanoparticles is still a problem. Thermoplastic nanofibrous structures can tackle this dispersion issue. Therefore, this paper investigated the effect of electrospun polyamide 6 nanofibrous structures on the mechanical properties of a glass fibre/epoxy composite. The nanofibres were incorporated in the glass fibre/epoxy composite as stand-alone interlayered structures and directly spun on the glass fibre reinforcement. Both ways of nanofibre incorporation have no negative effect on the impregnation of the epoxy. Moreover, the nanofibres remain well dispersed within the matrix. Incorporation of nanofibres increases the stress at failure in the 0 degrees-direction, the best results are obtained when the nanofibres are directly electrospun onto the glass fibres. Optical microscopic images also demonstrate that nanofibres prevent delamination when a 90 degrees crack reaches a neighbouring 0 degrees ply. Furthermore, mode I tests showed a small improvement when a thin nanofibrous structure is deposited directly onto the glass fibres. When the composites are loaded under 45 degrees, it is proven that, for an identical stress, the glass fibre composite with deposited nanofibres has less cracks than when interlayered nanofibrous structures are incorporated. Generally, it can be concluded that the addition of polyamide 6 nanofibres improves some mechanical characteristics of a glass fibre/epoxy composite. (C) 2013 Elsevier Ltd. All rights reserved.

However, the application of biocompatible polymers is vital to allow for their use in (bio)medical applications. Therefore, this paper focuses on the development and characterisation of pH-sensitive polycaprolactone (PCL) nanofibrous structures and PCL/chitosan nanofibrous blends with 20% chitosan. Electrospinning with added Nitrazine Yellow molecules proved to be an excellent method resulting in pH-responsive non-wovens. Unlike the slow and broad response of PCL nanofibres (time lag of more than 3 h), the use of blends with chitosan led to an increased sensitivity and significantly reduced response time (time lag of 5 min). These important effects are attributed to the increased hydrophilic nature of the nanofibres containing chitosan. Computational calculations indicated stronger interactions, mainly based on electrostatic interactions, of the dye with chitosan (Delta G of-132.3 kJ/mol) compared to the long-range interactions with PCL (Delta G of 35.6 kJ/mol), thus underpinning our experimental observations. In conclusion, because of the unique characteristics of chitosan, the use of PCL/chitosan blends in pH-sensitive biocompatible nanofibrous sensors is crucial. (C) 2012 Elsevier Ltd.

Even though a lot of literature is available on the electrospinning of nanofibres, only minor research has been performed on the effect of the relative humidity (RH). This paper investigates the influence of this parameter on the electrospinning process and fibre morphology of the hydrophilic polyamide 4.6 and the less hydrophilic polyamide 6.9. First, the electrospinning process and deposition area of the nanofibres is examined at 10, 50 and 70 % RH. Subsequently, the effect of the polyamide concentration and solvent ratio on the fibre morphology is investigated using scanning electron microscopy and differential scanning calorimetry. It was found that the nanofibre diameter decreased with increasing RH. This resulted in less stable crystals for polyamide 4.6 while electrospinning of polyamide 6.9 at higher RH led to slightly more stable crystals. In conclusion, the water affinity of a polymer is an important factor in predicting the nanofibre morphology at different humidities. journalArticle original public Article A1 published published ugent 5 Bert De Schoenmaker Bert De Schoenmaker aut author 002003264107 802000214244 978815731125 UGent Lien Van der Schueren Lien Van der Schueren aut author 002002166892 802000424715 UGent Ruphino Zugle Ruphino Zugle aut author Annelies Goethals Annelies Goethals aut author 002004215111 802000839185 971337473685 UGent Philippe Westbroek Philippe Westbroek aut author 801000885888 TW11 Paul Kiekens Paul Kiekens aut author 973210305734 0000-0002-8280-2108 UGent Tebello Nyokong Tebello Nyokong aut author Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department 41MC3410 e2b6ffa1-0585-4090-b87b-206153bb0f7c 2010-08-01 2012-07-31 0022-2461 2013 48 4 1746 1754 2013 Technology and Engineering ELECTROSPINNING PROCESS NANOCOMPOSITES info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/3118590/file/3118613 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 619413 bytes art_3A10.1007_2Fs10853-012-6934-9.pdf https://biblio.ugent.be/publication/3118590/file/3118605 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 855733 bytes Effect_of_the_relative_humidity_on_the_fibre_morphology_of_polyamide_4_6_and_polyamide_6_9_nanofibres_Bert_De_Schoenmaker_et_al_Karen_De_Clerck.pdf De Schoenmaker, Bert, Lien Van der Schueren, Ruphino Zugle, Annelies Goethals, Philippe Westbroek, Paul Kiekens, Tebello Nyokong, and Karen De Clerck. 2013. “Effect of the Relative Humidity on the Fibre Morphology of Polyamide 4.6 and Polyamide 6.9 Nanofibres.” JOURNAL OF MATERIALS SCIENCE 48 (4): 1746–1754. doi:10.1007/s10853-012-6934-9.

With these nonwovens, many applications can be targeted, such as water filtration. In this paper, polyamide nanofibrous membranes are evaluated for their pore size, a key parameter in water filtration, and for their removal of microorganisms. To increase the removal efficiency to values exceeding the state of the art, innovative functionalization of the nanofibres is studied. The nanofibrous membranes are functionalized using a one step method. Different functionalization chemicals are investigated which are Ag nanoparticles and bactericides. Ag functionalized nanofibres are used as a reference medium to compare with a novel bactericide based functionalization system. It is seen that nanofibrous membranes functionalized with the bactericides exceed the normal removal efficiencies obtained by microfiltration membranes. Furthermore, knowledge is built up on how these bactericides are inserted in the nanofibres themselves. journalArticle original public Article A1 published published ugent 4 Sander De Vrieze Sander De Vrieze aut author 802000062074 002001065843 TW11 Nele Daels Nele Daels aut author 002003290072 802000583955 977784615061 UGent Karel Lambert Karel Lambert aut author 001999183538 801001974716 TW03 Bjorge Decostere Bjorge Decostere aut author 000101067128 802000860205 976566687610 UGent Zeger Hens Zeger Hens aut author 801001028762 972250855290 0000-0002-7041-3375 WE06 Stijn Van Hulle Stijn Van Hulle aut author 801001539933 919019834884 971483871644 0000-0001-5773-7773 LA24 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department University College West Flanders HOWEST sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Department of Inorganic and physical chemistry (ceased 1-1-2018) WE06* sht department 01MR0110 e8ded5bb-d2f9-4991-ae4c-e97d04f71cd4 2010-05-01 2017-04-30 0040-5175 2012 82 1 37 44 2012 Technology and Engineering microorganisms Electrospinning water filtration WATER MEMBRANES FABRICATION SOLVENT info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/1917707/file/4397968 info:eu-repo/semantics/closedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 298968 bytes 0040517511416273.full.pdf https://biblio.ugent.be/publication/1917707/file/4397969 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 299863 bytes Filtration_performance_of_electrospun.pdf De Vrieze, Sander, Nele Daels, Karel Lambert, Bjorge Decostere, Zeger Hens, Stijn Van Hulle, and Karen De Clerck. 2012. “Filtration Performance of Electrospun Polyamide Nanofibres Loaded with Bactericides.” TEXTILE RESEARCH JOURNAL 82 (1): 37–44. doi:10.1177/0040517511416273.

This, however, requires that the nanofibrous structures are produced in a highly reproducible way. The article gives focus to polyamide (PA) 6.9, a less exploited PA though with interesting properties such as a very low moisture absorption. To trace and understand the dominant parameters that allow for the aimed reproducible characteristics, the influence of the solution parameters on the steady state behaviour during electrospinning as well as the resultant fibre morphology is followed by scanning electron microscopy and differential scanning calorimetry. Results show a significant effect of the amount of non-solvent acetic acid, added to the solvent formic acid, on the steady state behaviour and the fibre morphology. The non-solvent acetic acid broadens the steady state window by making the electrospin solutions more suitable to obtain uniform and reproducible nanofibrous structures with a narrow nanofibre diameter distribution. The mixture of the solvent formic acid and the non-solvent acetic acid strongly contributes to the future potentials of PA 6.9 nanofibres, with its leading to a smaller fibre distribution and moreover highly reproducible in time. journalArticle original public Article A1 published published ugent 5 Bert De Schoenmaker Bert De Schoenmaker aut author 002003264107 802000214244 978815731125 UGent Annelies Goethals Annelies Goethals aut author 002004215111 802000839185 971337473685 UGent Lien Van der Schueren Lien Van der Schueren aut author 002002166892 802000424715 UGent Hubert Rahier Hubert Rahier aut author Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department 0022-2461 2012 47 9 4118 4126 2012 Technology and Engineering NANOCOMPOSITES FIBERS PARAMETER STABILITY JETS info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/2034716/file/2034778 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 442380 bytes fulltextDOIPA69.pdf De Schoenmaker, Bert, Annelies Goethals, Lien Van der Schueren, Hubert Rahier, and Karen De Clerck. 2012. “Polyamide 6.9 Nanofibres Electrospun under Steady State Conditions from a Solvent/Non-Solvent Solution.” JOURNAL OF MATERIALS SCIENCE 47 (9): 4118–4126. doi:10.1007/s10853-012-6266-9.

For this purpose a spectrophotometric method based on the absorption of a negatively charged dye (Acid Orange 7) is extensively studied. The processing parameters have been optimized for analyzing small amounts of fibers and the feasibility of the method is examined by using two other well established techniques for nitrogen analysis. Good correlations were obtained between the different methods, however, the reproducibility of the Acid Orange 7 was superior to the other two methods. Moreover, statistically significant differences were found between fibers from cotton lines designed to produce oligochitin and control fibers without oligochitin. This shows that the proposed method is capable of accurately detecting increased nitrogen levels in bioengineered cotton fibers. journalArticle original public Article A1 published published ugent 4 Özgür Ceylan Özgür Ceylan aut author 002005040722 802000481295 972618734561 UGent Lieve Van Landuyt Lieve Van Landuyt aut author 801001285006 TW11 Lien Van der Schueren Lien Van der Schueren aut author 002002166892 802000424715 UGent M Hauben M Hauben aut author M De Block M De Block aut author Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department 0040-5175 2012 82 8 801 809 2012 Technology and Engineering bioengineered cotton screening reactivity Acid Orange 7 info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/2034810/file/2078092 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 292439 bytes Ceylan_2012_TRJ_82_8_801.pdf https://biblio.ugent.be/publication/2034810/file/2034853 info:eu-repo/semantics/closedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 225477 bytes 0040517511404595_full.pdf https://biblio.ugent.be/publication/2034810/file/2034857 info:eu-repo/semantics/closedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 373556 bytes TRJ_OC_Innovative_screening_of_novel_bioeng.pdf Ceylan, Özgür, Lieve Van Landuyt, Lien Van der Schueren, M Hauben, M De Block, and Karen De Clerck. 2012. “Innovative Screening of Novel Bioengineered Cotton Fibers Containing Oligochitin.” TEXTILE RESEARCH JOURNAL 82 (8): 801–809. doi:10.1177/0040517511404595.

The purpose of this paper is to produce uniform and reproducible nanofibrous PA 4.6 structures. Therefore, a mixture of the solvent formic acid and the nonsolvent acetic acid is used to dissolve and electrospin the PA 4.6. First the steady-state behaviour of the process and the boundary limits of the solution parameters needed for steady-state electrospinning are investigated. Subsequently, the effect of several solution and process parameters on the fibre morphology is examined, using microscopic techniques and thermal analysis. The polyamide concentration is found to be the dominant parameter affecting the fibre diameter and morphology. Furthermore, tensile tests are performed on upscaled nanofibrous structures and electrospun under optimised steady-state conditions. It is shown that the PA 4.6 nanofibrous structures, compared to nanofibrous nonwovens of PA 6 and PA 6.6, have a higher stress and strain at break. journalArticle original public Article A1 published published ugent 8 Bert De Schoenmaker Bert De Schoenmaker aut author 002003264107 802000214244 978815731125 UGent Lien Van der Schueren Lien Van der Schueren aut author 002002166892 802000424715 UGent Özgür Ceylan Özgür Ceylan aut author 002005040722 802000481295 972618734561 UGent Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department 1687-4110 2012 2012 860654 1 9 2012 Technology and Engineering NANOCOMPOSITES FIBERS FABRICATION WATER info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/2153977/file/2154029 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 5666523 bytes 860654_1_.pdf De Schoenmaker, Bert, Lien Van der Schueren, Özgür Ceylan, and Karen De Clerck. 2012. “Electrospun Polyamide 4.6 Nanofibrous Nonwovens: Parameter Study and Characterization.” JOURNAL OF NANOMATERIALS 2012: 1–9. doi:10.1155/2012/860654.

Owing to the high specific surface and low fibre diameter of nanofibres, they are very promising as secondary reinforcement for composites. Therefore, this research focuses on the mechanical properties of an epoxy resin with unidirectional glass fibres as primary reinforcement and polyamide 6 nanofibres as secondary reinforcement. Glass fibre composite plates are compared with composite plates with free interlayered nanofibrous nonwovens and with nanofibres directly electrospun on the unidirectional glass fibre mats. These interlayer nanofibrous structures, approximately 35 )!m thick, were obtained by solvent nozzle electrospinning and had an average fibre diameter of 136 ± 18 nm. The [OO,900h composite plates were produced through the resin transfer moulding process and mechanically characterized by tensile tests. The knee point of the composite plates significantly increased when nanofibres were added between the glass fibre layers, which imply that the matrix was strongly strengthened by the incorporated nanofibres. Also the shear modulus and strength under 45° increased with free interlayered nanofibres. When the nanofibres were directly electrospun on the glass fibres, the strength was even higher. Furthermore, the ratio of Poisson was considerably better when secondary nanofibres were added, especially when they were directly electrospun on the glass fibres. In conclusion, the nanofibrous nonwovens improve the mechanical properties of the glass fibre/epoxy composite plates, especially when loaded under 45°. This research highlights the advantages of adding nanofibres to glass fibre composites, and thus creating an innovative application area for nanofibres. conference public C3 published published ugent Bert De Schoenmaker Bert De Schoenmaker aut author 002003264107 802000214244 978815731125 UGent Ives De Baere Ives De Baere aut author 801001866905 977854465771 0000-0002-6846-0981 TW11 Wim Van Paepegem Wim Van Paepegem aut author 801001240344 972217192553 0000-0003-0672-3675 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials Science and Engineering (ceased 1-2-2017) TW10 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department Jeju, Korea 2012-05-29 2012-06-01 Jeju, Korea Korea Advanced Institute of Science and Technology, Korea 2012 6 6 2012 Technology and Engineering info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/2154244/file/2154245 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 935240 bytes Electrospin2012_De_Schoenmaker.pdf De Schoenmaker, Bert, Ives De Baere, Wim Van Paepegem, and Karen De Clerck. 2012. “The Influence of Polyamide 6 Nanofibres on the Mechanical Properties of Glass Fibre/Epoxy Composites.” In 2th International Conference on Electrospinning, Abstracts, 6–6.

The c1ectrospinning technique is a process for making continuous nanofibrcs in a nonwoven fonn. This process spins fibres ranging from 80 om diameter to several hundred nanometers. The non-woven structure is produced by app lying a high voltage to the anode, submerged in a spinn ing solution. This produces a charged jet of fluid when the electrical force is highcr than the surface tension of the solution and the fibres are collected on a grounded aluminum plate. Nanofibres have a small pore size and a large surface area to volume ratio compared to nonwovens (this ratio for a nanofibre can be as large as 1000 times of that of a microfibre). This, together with their low density and interconnected open pore structure. make the nanofibre nonwoven appropriate for a wide variety of filtration applications (Huang et al.. 2003). Due to the large effective surface areas. nanofibres can carry functional agents with different properties. such as biocidcs. With microfiltration membranes it is possible to retain suspended solids and micro-organisms. The added value of the tested nanofibre microfiltration membranes functionalized with silver nanoparticles (nAg) or other biocides to pathogen removal was studied. The biocides used in this study are commercially available. WSCP for example. is used as a cooling tower biocide and is applied directly into the water. Silver nanoparticles are nowadays implemented in a wide variety of consumer products for antimicrobial controL The aim of the study is to examine the effectiveness of different biocides and the possibility to electrospin them in a steady state nanofibre membrane. The results show that due to the silver nanoparticles and the funct ionalisation with biocides in the functionalized membrane a higher efficiency (3.9 10giO - 5,5 10glO) could be achieved. Further, the removal of pathogens is a factor 100 (2 10g10) higher with a WSCP (5%) than conventional microfihration. Functionalisation with Ag nanoparticles gave a 4 10gi0 removal. It is generally known that these particles only have effect on gram negative bacteria such as E. coli. WSCP and bronopol are bactericides that can be applicd on c1ectrospun nanofibres and it has also effect on gram positive bacteria (Chen et aI., 2008). The removal with a non-functionalised membrane is not as good as other micro-filtration studies. With other commercial membranes a 2 log I 0 - 4 logl 0 removal is possible (Zodrow et al.. 2009). conference public C3 published published ugent Nele Daels Nele Daels aut author 002003290072 802000583955 977784615061 UGent Annelies Goethals Annelies Goethals aut author 002004215111 802000839185 971337473685 UGent Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Stijn Van Hulle Stijn Van Hulle aut author 801001539933 919019834884 971483871644 0000-0001-5773-7773 LA24 Department of Mathematical Modelling, Statistics and Bio-informatics (ceased 1-1-2018) LA10 sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department University College West Flanders HOWEST sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Jeju, Korea 2012-05-29 2012-06-01 Jeju, Korea Korea Advanced Institute of Science and Technology 2012 38 38 2012 Technology and Engineering info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/2154246/file/2154304 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 972535 bytes Electrospin2012_Daels.pdf Daels, Nele, Annelies Goethals, Karen De Clerck, and Stijn Van Hulle. 2012. “Performance Assessment of Functionalized Electrospun Nanofibres for Removal of Pathogens.” In 2th International Conference on Electrospinning, Abstracts, 38–38.

However, the high demand for materials with specific properties indicates the need to eiectrospin polymer blends. Electrospinning of blends containing a synthetic and a natural polymer enables us to combine the favourable characteristics of both (e.g. biocompatibility and sufficient mechanical strength) into one material, which is often necessary in for example medical applications. A morphological characterization of these blend nanofibres is however crucial because there is a broader range of polymer properties influencing the resulting nanofibres. In this work, chitosanlpolycaprolactone (CS/PCL) solutions were electrospun using an acetic acid/fonnie acid solvent system to create antibacterial biodegradable blend nanofibres. The fibres were characterized and the parameters influencing the stability of the production process were analysed. The fibre characterisation includes techniques such as SEM, thennal analysis (using differential scanning calorimetry and dynamic mechanical analysis) and vibrational spectroscopy (infrared spectroscopy). It was found that by adding CS to a PCL electrospinning solution, the fibre diametcrs and deviat ions can be lowered because of two possible causes. The first is the presence of more charges due to the polycationic nature, possibly reducing thc diameter by more extensive jet splaying. The second effect of CS is a significant increase in viscosity, enabling the production of electrospinnable solutions with a lower total polymer concentration. Also other specific blend fibre properties, identified by a variation of techniques, can be linked to the CS addition.

More recently, pH-sensitive chromic textiles have also been investigated to a considerable extent, as the pH value is an important parameter in various circumstances. This review therefore elaborates on pH-sensitive textile materials. The outcome of this review process demonstrates that halochromic dyes can be successfully incorporated into textile materials, leading to flexible sensors. Various textile materials and different application methods have both been shown to be effective. Yet the textile material in which the pH-sensitive agent is present affects its halochromic behaviour and this factor should thus always be considered. Finally, this review establishes the major potential of pH-sensitive textile materials. journalArticle review public Review A1 published published ugent Lien Van der Schueren Lien Van der Schueren aut author 002002166892 802000424715 UGent Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department 01J04009 070a44f0-b14b-48f0-9f2a-a0ec5c90b554 2009-01-01 2013-10-31 1478-4408 2012 128 2 82 90 2012 Technology and Engineering PHOTOCHROMIC DYES SOL-GEL DISPERSE DYES AZO DYES SPECTRAL PROPERTIES AQUEOUS-SOLUTION OPTICAL SENSOR METHYL RED CONGO RED PART 1 info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/2064105/file/2064144 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 472077 bytes Coloration_and_application_of_pHsensitive_dyes.pdf Van der Schueren, Lien, and Karen De Clerck. 2012. “Coloration and Application of PH-Sensitive Dyes on Textile Materials.” COLORATION TECHNOLOGY 128 (2): 82–90. doi:10.1111/j.1478-4408.2011.00361.x.

A relatively simple synthesis and large variety of colours have made azo dyes the most abundant class of colourants. The dye studied in this research, ethyl orange (EO), is a prototypical example of a halochromic (pH-sensitive) azo dye. Halochromic dyes have already proven useful for application in textile sensors since the colour change of such sensors is easy to perceive and the advantages of the parent materials (e.g. flexibility) are maintained.[1] The key to further development of smart materials is combining multiple responses that can be separately addressed by different triggers.[2] To achieve this, we need a full knowledge of the colour changing mechanism and the influence of the environment. Herein, both theoretical and experimental methods were used to unravel the halochromic properties of EO.[3] Experimental UV-VIS and Raman spectra point towards a structural change of EO in water between pH 5 and pH 3. This pH-sensitivity is modeled through a series of ab initio computations on the neutral, various singly and doubly protonated structures. Static calculations (with inclusion of implicit solvation) are successful in assigning the most probable protonation site. However, to fully understand the origin of the main absorption peaks, a molecular dynamics simulation study in a water molecular environment is used in combination with Time Dependent-DFT calculations to deduce average UV-VIS spectra which take into account the flexibility of the dye and the explicit interactions with the surrounding water molecules. The proposed methodology allows to achieve a remarkable agreement between the theoretical and experimental UV-VIS spectrum and enables to fully unravel the pH sensitive behaviour of EO in aqueous environment.

This paper focuses on the solvent use in the production of PCL/chitosan nanofibres by solution electrospinning, since this is a crucial parameter in the electrospinning process. It was established that an acetic acid/formic acid shows great potential for the stable electrospinning of the blend. Additionally, the fibre morphology using this solvent system was analysed. journalArticle original public Article A1 published published ugent Iline Steyaert Iline Steyaert aut author 000060129993 802001072793 979860756278 UGent Lien Van der Schueren Lien Van der Schueren aut author 002002166892 802000424715 UGent Hubert Rahier Hubert Rahier aut author Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department 1022-1360 2012 321 1 71 75 2012 Technology and Engineering blends chitosan polycaprolactone electrospinning info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/3118558/file/3118576 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 136382 bytes 2012_marcomol_symp_Steyaert.pdf Steyaert, Iline, Lien Van der Schueren, Hubert Rahier, and Karen De Clerck. 2012. “An Alternative Solvent System for Blend Electrospinning of Polycaprolactone/Chitosan Nanofibres.” MACROMOLECULAR SYMPOSIA 321 (1): 71–75. doi:10.1002/masy.201251111.

Mature fibers show a typical sigmoidal isotherm, IUPAC type II, describing the adsorption on macroporous and non-porous adsorbents with a typical hysteresis. This is different from the type III isotherms exhibited by elongating fibers explained by the weak adsorbate-adsorbent interactions. The maximum sorption capacity clearly decreases throughout the cotton fiber development. This decrease is very rapid during the elongation phase of the fibers, but declines beyond 25 days post anthesis (DPA). This transition corresponds to the time point where the secondary cell wall becomes dominant over the primary cell wall, as confirmed with FT-IR. Also only little moisture hysteresis appeared during the elongation phase whereas from 25 DPA onwards a distinct hysteresis is observed that remains almost constant until maturation of the fiber. The study clearly elucidates the sorption mechanism during the elongation phase of the fiber to be different from the one during the secondary cell wall synthesis.

Experimental UV/Vis and Raman spectroscopy pointed towards a structural change of the azo dye with changing pH value (in the range pH 53). The pH-sensitive behavior was modeled through a series of ab initio computations on the neutral and various singly and doubly protonated structures. For this purpose, contemporary DFT functionals (B3LYP, CAM-B3LYP, and M06) were used in combination with implicit modeling of the water solvent environment.

Experimental UV/Vis and Raman spectroscopy pointed towards a structural change of the azo dye with changing pH value (in the range pH 53). The pH-sensitive behavior was modeled through a series of ab initio computations on the neutral and various singly and doubly protonated structures. For this purpose, contemporary DFT functionals (B3LYP, CAM-B3LYP, and M06) were used in combination with implicit modeling of the water solvent environment. Static calculations were successful in assigning the most-probable protonation site. However, to fully understand the origin of the main absorption peaks, a molecular dynamics simulation study in a water molecular environment was used in combination with time-dependent DFT (TD-DFT) calculations to deduce average UV/Vis spectra that take into account the flexibility of the dye and the explicit interactions with the surrounding water molecules.

The Kjeldahl method is used to validate the proposed method. A few transgenic lines designed to produce oligochitin and their respective controls were screened with the methods to see whether the proposed method is capable of accurately detecting the differences in nitrogen levels. Also a broad range of dyes from different classes are investigated. Their ability to detect differences in reactivity is to be proven using cotton fibres treated with different concentrations of a cationic agent. Four dyes of different classes and structures which show most promising results are proposed to screen dyeability differences between the bioengineered cotton lines. conference public C1 published published ugent Özgür Ceylan Özgür Ceylan aut author 002005040722 802000481295 972618734561 UGent Lieve Van Landuyt Lieve Van Landuyt aut author 801001285006 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Portorož, Slovenia 2012-09-15 2012-09-17 9789612483562 Portorož, Slovenia University of Maribor 2012 18 22 2012 Technology and Engineering reactivity dye absorption bioengineered cotton info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/3004663/file/3004672 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 440589 bytes CEC_PROCEEDINGS_-_2012_CEYLAN.pdf Ceylan, Özgür, Lieve Van Landuyt, and Karen De Clerck. 2012. “Dye Absorption Method for the Evaluation of Novel Bioengineered Cotton Fibres.” In 7th Central European Conference on Fibre-Grade Polymers, Chemical Fibres and Special Textiles, Proceedings, 18–22.

Recent advances in biotechnology, especially in genetic engineering, offer an alternative route to alter reactivity of cotton fibres and thus to reduce the environmental impact and energy consumption of conventional cotton processing. However the success of this breakthrough approach is dependent on the early selection of new fibre types with the best performance. This requires novel tests that use only small amounts of fibre sample due to the very limited availability of bioengineered lines. For this purpose, a semi industrial dyeing method is extensively studied. The method is validated by a well established technique for nitrogen analysis, the Kjehdahl method, using cotton fibres treated with a commercially available cationic agent at various concentrations. conference meetingAbstract public C3 published published ugent Özgür Ceylan Özgür Ceylan aut author 002005040722 802000481295 972618734561 UGent Lieve Van Landuyt Lieve Van Landuyt aut author 801001285006 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Giuliano Freddi Giuliano Freddi edt editor Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Milan, Italy 2011-03-02 2011-03-04 Milan, Italy Stazione Sperimentale per la Seta 2011 abstract F.105 2011 Technology and Engineering bioengineering cotton fibres reactivity info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/1186180/file/1186190 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 92808 bytes Small_Scale_Dyeing_Method_to_Evaluate_Novel_Bioengineered_Cotton_Fibres_a_Feasibility_Study.pdf Ceylan, Özgür, Lieve Van Landuyt, and Karen De Clerck. 2011. “Small Scale Dyeing Method to Evaluate Novel Bioengineered Cotton Fibres : A Feasibility Study.” In Polymer and Textile Biotechnology, 7th International Conference, Abstracts, ed by.

It is a well known fact that malaria and dengue fever are amongst the most killing diseases in the world: 500 million people a year are infected with malaria and more than a million people die of the disease, i.e. one person every 30 seconds, of which 90% are children, and an estimated 100 million cases of dengue fever and 250000 cases of dengue hemorrhagic fever occur annually. As a result of global warming of the earth, the problem is expanding and is even becoming a threat for Europe. conference meetingAbstract public C3 published published ugent Vincent Nierstrasz Vincent Nierstrasz aut author 802000230513 TW11 Lucy Wanjiru Ciera Lucy Wanjiru Ciera aut author 000081414120 802000854848 975665422618 UGent Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Lieva Van Langenhove Lieva Van Langenhove aut author 801000648543 972198930382 0000-0001-9802-7399 TW11 TW18 Giuliano Freddi Giuliano Freddi edt editor Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Milan, Italy 2011-03-02 2011-03-04 41U00109 e4dcf902-3697-4547-b327-0a25ca337730 2009-10-15 2013-10-14 Milan, Italy Stazione Sperimentale de la Seta 2011 abstract A.111 2011 Technology and Engineering textile bio-aggregates malaria mosquito repellent textiles biomimetics protective textile dengue info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/1186198/file/1186221 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 64717 bytes NO_BUG_Novel_Release_Systems_and_Biobased_Utilities_for_Insect_Repellent_Textiles.pdf Nierstrasz, Vincent, Lucy Wanjiru Ciera, Karen De Clerck, and Lieva Van Langenhove. 2011. “NO BUG : Novel Release Systems and Biobased Utilities for Insect Repellent Textiles.” In Polymer and Textile Biotechnology, 7th International Conference, Abstracts, ed by.

Their hydrophilic nature is a key characteristic for many applications. However, because of their high porosity, it is difficult to measure the hydrophilicity of nanofibrous structures with contact-angle measurements. Therefore, characterization through wicking behavior is more appropriate. The International Organization for Standardization norm on wicking needs some refining to account for the specific nature of highly porous nanofibrous structures. A refined method was used on several structures that differed in the fiber diameter and the polyamide type. The structures with the thickest nanofibers had the highest wicking rates. At equilibrium, the wicking heights of structures of different polyamide types with the same average fiber diameter followed the trend expected from their intrinsic hydrophilicity. In the initial phase, the capillary forces established the wicking behavior. Later in the process, the wicking behavior was determined by the capillary forces and the hydrophilicity. In conclusion, the hydrophilicity of nanofibrous structures can be successfully determined by an optimized wicking procedure, and the fiber diameter is the dominant parameter for the resulting wicking height at equilibrium.

Although the working principle of electrospinning is rather straight forward, it is influenced by many parameters. There is still a serious lack of knowledge concerning the influence of the ambient parameters, for which preliminary knowledge reveals that the relative humidity is of primary importance. This article reports the influence of the relative humidity on electrospun polyamide 6 nanofibres. Mixtures of formic acid and acetic acid are used for steady state electrospinning of polyamide 6 nanofibres, for which a steady state table is determined. When the relative humidity increases, the average fiber diameter decreases and the fraction of the less stable c-phase crystals in the polyamide diminishes. This effect is explained by absorbed water acting as a plasticizer, reducing the Tg of the polyamide. This article shows the importance of working in climatized conditions during electrospinning to obtain reproducible nanofibres. (C) 2010 Wiley Periodicals, Inc.

A possible application of this textile pH-sensor can be found in wound dressings. In addition to the use of traditional textile materials such as cotton gauze, nanofibrous nonwovens may provide benefits in medical applications. This paper discusses the development of pH-sensitive cotton fabrics by the combination of standard pH-indicator dyes with standard dyeing processes. Also halochromic polyamide nanofibres were produced by adding the pH-indicator dyes to the polymer solution. Both approaches were found to be promising. After the immobilization of the dye on a textile structure, still a clearly visible colour change was present for most of the dye-textile systems. It should however be noted that the behaviour of the pH-indicator dye was dependent on the medium in which it is incorporated. conference public C1 published published ugent Lien Van der Schueren Lien Van der Schueren aut author 002002166892 802000424715 UGent Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Tampere, Finland 2011-06-28 2011-06-30 Tampere, Finland Tampere University of Technology 2011 1 5 2011 Technology and Engineering info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/1897078/file/1897081 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 49479 bytes Fibermed11_voorblad_proceedings.pdf https://biblio.ugent.be/publication/1897078/file/1897082 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 384450 bytes VanderSchueren_paper.pdf Van der Schueren, Lien, and Karen De Clerck. 2011. “PH-Sensitive Textile Materials as Innovative Wound Dressings.” In International Conference on Fibrous Products in Medical and Health Care, Proceedings, 1–5.

Therefore new developments in water treatment are needed. One of such new developments is presented in this study. Nanofiber membranes produced by the electrospinning technique offer great potential in water filtration. Nanofiber structures have a small pore size, a large specific surface area and interconnected open pore structure which makes them appropriate for water filtration. However, the pathogen removal efficiency is not yet satisfactory. To improve this, disinfectants as a functional agent on nanofiber membranes were used in this study. The pathogen removal of the functionalized membranes was evaluated with wastewater from a general hospital with ca. 107 culturable organisms per 100 ml before filtration. Pathogen removal of about 4 to 5,5 log10 is possible with selected biocides. This is higher than a nanofibers membrane without disinfectant, which gives a removal of 2 log10 and commercial membranes with a removal of 3 to 4 log10. In addition to this, the biocides stay immobilized inside the membrane and only a limited fraction (10%) leaches into the water. conference public C1 published published ugent Annelies Goethals Annelies Goethals aut author 002004215111 802000839185 971337473685 UGent Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 N Daels N Daels aut author I Scampers I Scampers aut author Stijn Van Hulle Stijn Van Hulle aut author 801001539933 919019834884 971483871644 0000-0001-5773-7773 LA24 Department of Mathematical Modelling, Statistics and Bio-informatics (ceased 1-1-2018) LA10 sht department University College West Flanders HOWEST sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Tampere, Finland 2011-06-28 2011-06-30 Tampere, Finland Tampere University of Technology 2011 2011 Technology and Engineering info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/1897083/file/1897086 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 49479 bytes Fibermed11_voorblad_proceedings.pdf https://biblio.ugent.be/publication/1897083/file/1897087 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 280181 bytes Goethals_paper.pdf Goethals, Annelies, Karen De Clerck, N Daels, I Scampers, and Stijn Van Hulle. 2011. “Functionalized Nanofiber Membranes for Disinfection of Water.” In FiberMed11 : International Conference on Fibrous Products in Medical and Health Care.

Thanks to this, they can be used as filtration membranes. Nanofiber membranes have high clean water permeability values, however the pathogen removal efficiency is currently not satisfactory. For this reason, we functionalized the membranes with antibacterial particles, such as silver nanoparticles and commercial biocides, by adding them into the spinning solution. Afterwards, the membranes were characterized to study the effect of the functionalization on the fiber diameter and pathogen removal efficiency. The distribution of the silver nanoparticles was studied with SEM and TEM images. TEM-images showed that the silver nanoparticles are trapped inside the nanofibers. SEM-images confirmed that the average fiber diameter is not affected by the functionalization. To evaluate the removal of pathogens, water samples were taken from waste water from a general hospital (107 – 108 colony forming units per 100 ml) and were filtered with different membranes. A non functionalized nanofiber membrane could not achieve the same reduction in culturable organisms as commercial membranes (2 log10 – 4 log10 removal). Higher reduction was reached when silver nanoparticles were added to the membrane. A 3 log10 – 4 log10 removal was reached by adding silver nanoparticles to the spinning solution. Nanofiber membranes with biocides as functionalization agents achieved even a much higher reduction, up to 5,5 log10, which is competitive with commercial membranes currently on the market. In conclusion, the electrospinning process allows the functionalization of nanofiber membranes with antibacterial particles. This highly improves the pathogen removal efficiency of the membranes. conference public C3 published published ugent Annelies Goethals Annelies Goethals aut author 002004215111 802000839185 971337473685 UGent Nele Daels Nele Daels aut author 002003290072 802000583955 977784615061 UGent Imca Sampers Imca Sampers aut author 802000197874 978769808190 0000-0001-5536-7852 LA23 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Stijn Van Hulle Stijn Van Hulle aut author 801001539933 919019834884 971483871644 0000-0001-5773-7773 LA24 Department of Mathematical Modelling, Statistics and Bio-informatics (ceased 1-1-2018) LA10 sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department University College West Flanders HOWEST sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Montpellier, France 2011-09-12 2011-09-15 Société Française de Métallurgie et de Matériaux ; Associazione Italiana di Metallurgia 2011 abstract A42-O-5-4 2011 Technology and Engineering info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/1903380/file/1903388 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 70449 bytes Euromat_2011_-_Goethals.pdf Goethals, Annelies, Nele Daels, Imca Sampers, Karen De Clerck, and Stijn Van Hulle. 2011. “Electrospun Nanofiber Membranes Functionalized with Antibacterial Particles.” In EUROMAT 2011, Abstracts.

These chameleon textiles can be seen as the artificial equivalent of the colour changing species found in nature. A colour change of a textile material may provide information concerning the surrounding medium and a chameleon textile has thus possible uses as warning sensor. Within the group of colour changing textiles, halochromic textiles, which vary in colour depending on the pH, offer major potentials since a whole range of processes in nature are affected by this parameter. For example, during the healing process of a wound, the pH-value of the skin varies. The progress of the healing process could thus be indicated by a pH-sensitive wound dressing which may avoid unnecessary removal of the dressing. The aim of the current research is to develop pH-sensitive textile sensors through the application of pH-sensitive dyes on various textile materials. pH-indicators, normally used to indicate the pH of aqueous solutions, will be used as pH-sensitive dyes since they are easy available and possibly show high affinity for textiles as their molecular structures are similar to the one of standard dyes. Conventional textile fabrics such as cotton and polyamide will be investigated as substrate material for the pH-indicator dyes. Besides these traditional textile materials, also nanofibrous nonwovens will be incorporated with the dyes as the typical characteristics of nanofibres (such as high surface area, small pore size) may provide benefits in various medical applications. The results of our study showed that conventional textile materials can be dyed with pH-indicator dyes using standard dyeing processes. Nanofibrous nonwovens could, as expected, not be dyed with these standard processes but can be coloured by a direct incorporation of the dyes in the polymer solution before the electrospinning process. The halochromic study after the application of the dyes showed that a clearly visible colour change with pH was still present on the textile materials for most of the dye-textile systems. With this it should be noted that the halochromic behaviour of the dyes on the different textile materials was dependent on the surrounding medium due to the different dye-fibre interactions. conference public C3 published published ugent Lien Van der Schueren Lien Van der Schueren aut author 002002166892 802000424715 UGent Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Montpellier, France 2011-09-12 2011-09-15 01J04009 070a44f0-b14b-48f0-9f2a-a0ec5c90b554 2009-01-01 2013-10-31 Société Française de Métallurgie et de Matériaux ; Associazione Italiana di Metallurgia 2011 abstract F12-O-2-6 2011 Technology and Engineering info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/1903396/file/1903431 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 102967 bytes Euromat_2011_-_Van_der_Schueren.pdf Van der Schueren, Lien, and Karen De Clerck. 2011. “PH-Sensitive Textile Sensors with Possible Use as Wound Dressings.” In EUROMAT 2011, Abstracts.

Because of their very small fibre diameter these fibrous materials have specific and unique characteristics such as a high surface-to-volume ratio and high porosity. Thanks to this these nanofibres can be used in a broad spectrum of applications such as liquid and air filtration, wound bandages and composites. Although the literature on nanofibre composites is restricted, nanofibres can have advantages for advanced composites. Composites reinforced with conventional glass or carbon fibres may have very high tensile strengths, but the impact resistance is sometimes limited. A second problem of these actual composites is the delamination of the several textile layers. Both problems can be reduced by using nanofibrous webs between the glass or carbon layers. In our research large polyamide nanofibrous structures (PA 6, PA6.6, PA 4.6 and PA 6.9) were produced on a multi-nozzle setup. Starting from these structures the effect of the nanofibres on the curing of a epoxy matrix was investigated by thermo analytical measurements using a differential scanning calorimeter. Changing the nanofibres characteristics, especially the polyamide type and fibre diameter, will affect the curing behaviour of the resin. Furthermore the influence of the amount of water absorbed through the nanofibrous webs is inquired, by making identical composite samples at different relative humidity’s. In the second part of the research glass fibre/polyamide nanofibre composites were produced on large scale by infusion. The polyamide nanofibres were brought into the composites as stand-alone structures as well as coatings on the glass fabrics. The tenacity of these composites is compared to glass fibre composites without nanofibres. This research gives a good overview of the curing behaviour of the resin affected by the nanofibrous webs on the one side and the advantages of nanofibres for high performance composites on the other side. conference public C3 published published ugent Bert De Schoenmaker Bert De Schoenmaker aut author 002003264107 802000214244 978815731125 UGent Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Montpellier, France 2011-09-12 2011-09-15 IOF10STEP001W 19791cfe-91df-4bbd-b61d-914dd90e6ccb 2010-02-01 2012-02-28 Société Française de Métallurgie et de Matériaux ; Associazione Italiana di Metallurgia 2011 abstract B31-P-1-44 2011 Technology and Engineering info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/1903434/file/1903453 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 247246 bytes Euromat_2011_-_De_Schoenmaker.pdf De Schoenmaker, Bert, and Karen De Clerck. 2011. “The Influence of Nanofibres in Composite Materials.” In EUROMAT 2011, Abstracts.

PCL nanofibres, produced by electrospinning, could provide new characteristics that are of interest for these applications. Nanofibrous structures indeed show unique properties such as higher specific surface area, higher porosity and smaller pore size compared to microfibres. At present the most commonly used solvent for electrospinning PCL is chloroform, but this only leads to fibres in the microscale range. A key issue in electrospinning PCL is thus the ability to obtain bead-free fibres with diameters in the nanoscale range. To obtain these small diameter nanofibres of PCL various solvent systems were examined. The innovative solvent mixture formic acid/acetic acid was found to allow for nanofibres with a diameter ten times smaller than the one obtained by chloroform. Steady state conditions could be obtained which thus allow electrospinning in a stable and reproducible way. Moreover, GPC measurements on the PCL pellet and the produced nanofibrous structures showed that there was no degradation of PCL during the electrospinning process from the acid solution. Further it was noticed that the average fibre diameter decreased with decreasing polymer concentration. The solvent ratio was found to have a minor influence on the fibre diameter but showed a significant effect on the fibre diameter distribution with a decreasing standard deviation with increasing amount of formic acid. Also the humidity, an often overlooked yet important parameter, was noted to affect both diameter characteristics. Generally it can be concluded that the solvent system formic acid/acetic acid could fill the gap in electrospinning PCL since it is readily able to produce uniform fibres in the nanoscale range. conference public C3 published published ugent Lien Van der Schueren Lien Van der Schueren aut author 002002166892 802000424715 UGent Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Lyon, France 2011-05-29 2011-05-31 2011 abstract P.3.161 2011 Technology and Engineering polycaprolactone electrospinning steady state nanofibres info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/1903484/file/1903493 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 664650 bytes POLY2011_0169.pdf Van der Schueren, Lien, and Karen De Clerck. 2011. “An Alternative Solvent System for the Steady State Electrospinning of Polycaprolactone.” In Frontiers in Polymer Science, 2nd International Symposium, Programme Book and CD of Abstracts.

Polyamide 6.9 is a seldom used polyamide though with specific properties such as the lowest water absorption of all polyamides. This can, for example, be advantageous for nanofibres in composite applications. Acetic acid/formic acid solvent mixtures prove to be very suitable for the steady state electrospinning of PA 6.9, with the formic acid serving the solubility of the PA 6.9 and the acetic acid serving the appropriate solution characteristics for obtaining steady state. Steady state behaviour means no irregularities in the nanofibrous structures and a high reproducibility A limited range of polymer concentrations, solvent ratios and process parameters results in steady state electrospinning. The combination of those parameters is determined by the viscosity, surface tension and electric properties of the electrospinning solutions. Different steady state tables showing the limits within a varying polymer concentration and solvent ratio that allow for the production of nanofibres are composed. Sequentially the influence of the main solution and process parameters on the fibre diameter (using SEM) and thermal behaviour (using DSC and XRD) is investigated. The polymer concentration has a significant effect on the morphology of the nanofibres: the average PA 6.9 diameter and the fraction less stable crystal phase increase with increasing polymer concentration. The effect of the solvent ratio is less obvious. The process parameters only have a minor effect on the nanofibres. The applied voltage and TCD show no influence on the nanofibre morphology. The flow rate has a small influence on the fibres, but the difference in diameters is small compared to the differences found with varying polymer concentration. It can be concluded that the polymer concentration is the key parameter to alter the fibre morphology of PA 6.9 nanofibres. conference public C3 published published ugent Bert De Schoenmaker Bert De Schoenmaker aut author 002003264107 802000214244 978815731125 UGent Annelies Goethals Annelies Goethals aut author 002004215111 802000839185 971337473685 UGent Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Lyon, France 2011-05-29 2011-05-31 2011 abstract P.3.162 2011 Technology and Engineering Nanofibres Electrospinning Polyamide 6.9 info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/1903494/file/1903505 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 46899 bytes POLY2011_0176.pdf De Schoenmaker, Bert, Annelies Goethals, and Karen De Clerck. 2011. “Morphology Study of Polyamide 6.9 Nanofibres Electrospun under Steady State Conditions.” In Frontiers in Polymer Science, 2nd International Symposium, Programme Book and CD of Abstracts.

Design/methodology/approach - As a start point, the feasibility of incorporating pH-indicators in conventional textiles using standard dyeing processes was investigated. Next, a pH-indicator was incorporated into a nylon nanofibrous structure by adding the dye to the polymer solution before the start of the electro-spinning process. Findings - The authors' results proved that it is possible to develop a pH-sensor using conventional textiles dyed by a standard dyeing process. Also, the incorporation of a pH-indicator dye into a nanofibrous structure was possible. Moreover, reproducible samples could be obtained. Furthermore, the majority of the obtained textile structures showed a clear colour change with a change in acidity. This halochromic behaviour was, however, different from the behaviour of the dyes in solution due to dye-fibre interactions. Originality/value - The knowledge obtained in this study can lead to the development of a textile pH-sensor. This sensor can be used in a broad field of applications since a colour change is a non-disturbing but clear signal which can perform a first warning function. journalArticle proceedingsPaper public Article; Proceedings Paper A1 published published ugent 11 Lien Van der Schueren Lien Van der Schueren aut author 002002166892 802000424715 UGent Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department 01J04009 070a44f0-b14b-48f0-9f2a-a0ec5c90b554 2009-01-01 2013-10-31 0955-6222 2011 23 4 269 274 2011 Technology and Engineering Textiles DYES Acidity Colours technology Alkalinity info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/1920674/file/1920677 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 138229 bytes VanderschuerenIntJClothSciTech.pdf https://biblio.ugent.be/publication/1920674/file/1920678 info:eu-repo/semantics/closedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 74159 bytes __www.emeraldinsight.com_journals.htm_issn_0955-6222_volum.pdf Van der Schueren, Lien, and Karen De Clerck. 2011. “Textile Materials with a PH-Sensitive Function.” INTERNATIONAL JOURNAL OF CLOTHING SCIENCE AND TECHNOLOGY 23 (4): 269–274. doi:10.1108/09556221111136539.

In this process, the early selection of fibers with the best performance is of utmost importance. However, due to the limited availability of these specialty fibers, the use of available test methods is limited and thus new test methodologies are needed. The aim of this paper is to study Cone calorimetry for the characterization of cotton fibers. One of the main aspects of the procedure, namely sample weight, is optimized to improve the reproducibility. conference public C3 published published ugent Özgür Ceylan Özgür Ceylan aut author 002005040722 802000481295 972618734561 UGent Lieve Van Landuyt Lieve Van Landuyt aut author 801001285006 TW11 J Alongi J Alongi aut author A Frache A Frache aut author Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Alessandria, Italy 2011-06-26 2011-06-30 Alessandria, Italy Politecnico di Torino 2011 1 2 2011 Technology and Engineering info:eu-repo/semantics/openAccess https://biblio.ugent.be/publication/2085018/file/2085027 info:eu-repo/semantics/openAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 721715 bytes Cone_calorimetry.pdf Ceylan, Özgür, Lieve Van Landuyt, J Alongi, A Frache, and Karen De Clerck. 2011. “Cone Calorimetry as a Useful Technique for the Screening of Cotton Fibers.” In 13th European Meeting on Fire Retardant Polymers, Abstracts, 1–2.

The effect of the addition of pH-sensitive dyes to the polymer solution is however unknown. Moreover also the halochromic behaviour of the resulting nonwovens can be influenced by this incorporation. Therefore, we studied the production of halochromic nano nonwovens by adding various pH-indicator dyes to a polyamide 6.6 polymer solution prior to electrospinning. Next, the halochromism of two selected dyes (Bromocresol Purple and Brilliant Yellow) was investigated as case studies. Our results show that the pH-indicator addition has no influence on the average fibre diameter. Poorly dissolved dyes cause however instabilities in the process as seen by the droplet formation. The investigated nanofibrous structures showed a clear colour change with a change in pH. This halochromic behaviour was however different from the behaviour of the dye in solution due to dye-fibre interactions. Generally it can be concluded that a nanofibrous pH-sensor can be developed by electrospinning with incorporated pH-indicator dyes. (C) 2010 Elsevier Ltd. All rights reserved.

Steady state conditions are essential in nozzle electrospinning to generate a stable process which fabricates reproducible material, permitting industrial upscaling. This study shows that only a limited mixture range of formic acid/acetic acid allows electrospinning of polyamide 6.6 in steady state. Furthermore, the weight concentration in solution; the tip to collector distance and the flow rate have been changed to control the average diameter of the nanofibres. The average diameter increases by increasing weight concentration in solution, increasing volume fraction of acetic acid in the mixture, increasing tip to collector distance and increasing flow rate.

However due to the high porosity of the structures, it is difficult to measure this property with contact angle measurements. Therefore a characterisation through wicking behaviour is more appropriate. The ISO-norm on wicking behaviour needs some refining to account for the specific nature of the highly porous nanofibrous structures. This refined method is used on polyamide 6 nanofibrous structures with different diameters and on polyamide 6 nanofibres with an incorporated hydrophilic compound. It was found that the fibre diameter is the major characteristic which influences the wicking behaviour. conference public C1 published published ugent Bert De Schoenmaker Bert De Schoenmaker aut author 002003264107 802000214244 978815731125 UGent Sander De Vrieze Sander De Vrieze aut author 802000062074 002001065843 TW11 Philippe Westbroek Philippe Westbroek aut author 801000885888 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Vilnius, Lithuania 2010-06-21 2010-06-23 9789955258292 AUTEX 2010 2010 Technology and Engineering hydrophilicity Electrospinning wicking behaviour nanofibrous structures info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/988965/file/988966 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 120383 bytes WICKING_PROPERTIES_OF_POLYAMIDE_NANOFIBROUS_STRUCTURES.pdf De Schoenmaker, Bert, Sander De Vrieze, Philippe Westbroek, and Karen De Clerck. 2010. “Wicking Properties of Polyamide Nanofibrous Structures.” In World Textile Conference, 10th, Proceedings.

Therefore, a new method to examine the wicking behaviour of the structures is developed. This method is used on several structures, which differ in fibre diameter and polyamide type. The structures with the thickest nanofibres have the highest wicking rates. For different polyamide types, the capillary forces establish the wicking behaviour in the initial phase. Further in the process, it is determined by the capillary forces and the water absorption capacity of the bulk phase. conference public C1 published published ugent Bert De Schoenmaker Bert De Schoenmaker aut author 002003264107 802000214244 978815731125 UGent Sander De Vrieze Sander De Vrieze aut author 802000062074 002001065843 TW11 Philippe Westbroek Philippe Westbroek aut author 801000885888 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Merih Sariisik Merih Sariisik edt editor Gülseren Karabay Gülseren Karabay edt editor Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Istanbul, Turkey 2010-05-16 2010-05-18 9789754412857 Istanbul, Turkey Dokuz Eylül University.

Although previously categorized as unwanted, colour changing textiles can be used in a broad field of applications since a colour change is a non-disturbing but clear signal which can perform a first warning function. This research focuses on halochromism or pH-sensitivity due to the importance of pH. These kind of materials can be applied in wound dressings, geotextiles, protective clothing etc. A halochromic wound dressing would for example be able to indicate the healing process of a wound since the pH-value varies during healing. Thanks to their extremely fine fibres, nanofibrous structures show interesting characteristics such as small pore size, high porosity and high specific surface area, which turn them suitable for a whole range of applications. Incorporating pH-sensitive dyes into nanofibrous structures would lead to unique materials that combine the intrinsic properties of nanofibres with an extra sensor functionality. As a start point, the feasibility of incorporating pH-indicator dyes in conventional textiles using standard dyeing processes was investigated. Next, the dyes were incorporated into a polyamide 6.6 nanofibrous structure by adding the dyes to the polymer solution before the start of the electrospinning process. The influence of this incorporation on the electrospinning process and the halochromic properties of the obtained structures were investigated. Our results proved that it is possible to develop a pH-sensor using conventional textiles dyed by a standard dyeing process. Also the incorporation of the pH-indicator dyes into a nanofibrous structure was possible. Moreover, the process parameters and fibre diameters were not influenced by this addition and reproducibility could be obtained. Furthermore, the majority of the obtained textile structures showed a clear colour change with a change in acidity. This halochromic behaviour was however different from the behaviour of the dyes in solution due to dye-fibre interactions. conference public C1 published published ugent Lien Van der Schueren Lien Van der Schueren aut author 002002166892 802000424715 UGent Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Merih Sariisik Merih Sariisik edt editor Gülseren Karabay Gülseren Karabay edt editor Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Istanbul, Turkey 2010-05-16 2010-05-18 9789754412857 Istanbul, Turkey Dokuz Eylül University.

Some very specific application fields are targeted in the literature about electrospinning. One of these research fields is filtration. In this field, mainly air filtration is targeted. Recent studies showed the strong performance of nanofibrous material in liquid filtration. For liquid (such as water) filtration the material needs to be flawless and pressure resistant. To cope with the first problem, we have developed a specific technology based on nozzle electrospinning. The key feature in our technology is the possibility to electrospin under steady state conditions. In each time period, the amount of polymer that is pumped out of the needle as a solution is the same as the amount of polymer that is deposited in the form of nanofibers. In the case of water filtration, a polyamide 6 nanofibrous nonwoven is created. The polyamide is chosen because of its high inherent strength. This high mechanical strength makes it possible for the material to withstand the pressure applied on the material during filtration. At this moment, projects are running to investigate if the polyamide 6 nanofibrous structures give an added value in the field of water filtration. The first results show that nanofibres enhance the water flux values at the same pressure. Next to flux investigations, experiments concerning the use of the membranes in a membrane bioreactor (MBR) are performed. These experiments show that the nanofibrous material has the same filtration efficiency as commercial MBR membranes. It even surpasses that efficiency with an extra functionalisation. conference public C1 published published ugent Sander De Vrieze Sander De Vrieze aut author 802000062074 002001065843 TW11 N Daels N Daels aut author Philippe Westbroek Philippe Westbroek aut author 801000885888 TW11 Stijn Van Hulle Stijn Van Hulle aut author 801001539933 919019834884 971483871644 0000-0001-5773-7773 LA24 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Merih Sariisik Merih Sariisik edt editor Gülseren Karabay Gülseren Karabay edt editor University College West Flanders HOWEST sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Istanbul, Turkey 2010-05-16 2010-05-18 9789754412857 Istanbul, Turkey Dokuz Eylül University.

With a diameter ranging from 80 nm to several hundred nanometers, the nanofibres have a large surface area to volume ratio and a very high porosity. The aim of the study was to evaluate the use of nanofibre microfiltration membranes in three different membrane bioreactor (MBR) set-ups. More specific, in an active sludge MBR (AS-MBR), an AS-MBR with flux performing enhancer MPE50 and in a trickling filter MBR (TF-MBR). The results showed that the nanofibre membrane performed best with the TF-MBR. This was due to the removal of turbidity by the trickling filter, and also because of a new membrane module configuration. The flux was higher than the other configurations, and more important, the flux was stable for 85 days after which the experiment was stopped. Also different cleaning techniques with 0.5% NaOCl and 0.2% HCl were tested and compared in this study. The nanofibre membrane structure and strengths were not affected after the procedures for cleaning. Scanning electron micrograph (SEM) pictures show the nanofibre membrane being clean after 12 h of the alkali and acid treatment. (C) 2010 Elsevier B.V. All rights reserved.

As such, this study bridges the gap between developments in electrospinning techniques for the production of flat-sheet membranes and the application of these membranes in water filtration. Three different applications were examined. Firstly, the use of the membrane (functionalised or non-functionalised) for the removal of pathogens was investigated. Secondly, the electrospun flat-sheet membranes were applied for wastewater treatment in a laboratory-scale submerged membrane bioreactor (MBR). In addition to these applications, physical properties such as clean water permeability (CWP) and strength were also examined. The tests showed that the electrospun membranes can be used for water filtration applications, but that further improvements are necessary before these membranes can be practically employed. In particular, the level of functionality and the properties of irreversible fouling require further research. journalArticle original public Article A1 published published ugent 16 Bjorge Decostere Bjorge Decostere aut author 000101067128 802000860205 976566687610 UGent Nele Daels Nele Daels aut author 002003290072 802000583955 977784615061 UGent Sander De Vrieze Sander De Vrieze aut author 802000062074 002001065843 TW11 Pascal Dejans Pascal Dejans aut author 972309636987 UGent Tamara Van Camp Tamara Van Camp aut author 801001940663 001998321046 UGent Wim Audenaert Wim Audenaert aut author 000080787357 802000510395 976625357856 UGent Philippe Westbroek Philippe Westbroek aut author 801000885888 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Charlotte Boeckaert Charlotte Boeckaert aut author 801001798597 001998202828 UGent Stijn Van Hulle Stijn Van Hulle aut author 801001539933 919019834884 971483871644 0000-0001-5773-7773 LA24 University College West Flanders HOWEST sht department Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department 0378-4738 2010 36 1 151 155 2010 Technology and Engineering WASTE-WATER MICROFILTRATION MEMBRANES MBR pathogen removal microfiltration electrospinning nanofibre info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/881386/file/887660 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 600832 bytes Decostere_2010_WaterSA_36_1_151.pdf Decostere, Bjorge, Nele Daels, Sander De Vrieze, Pascal Dejans, Tamara Van Camp, Wim Audenaert, Philippe Westbroek, Karen De Clerck, Charlotte Boeckaert, and Stijn Van Hulle. 2010. “Initial Testing of Electrospun Nanofibre Filters in Water Filtration Applications.” WATER SA 36 (1): 151–155. manuscript reference no. 2425 Ghent University Library pug01:881386 2010-02-25T11:58:48Z 2026-03-31T14:52:08Z eng public 801000739277 1 false higher-education 2010 1 false higher-education 2010 http://hdl.handle.net/1854/LU-947706 10.1177/0040517509346443 000276772000002 eng No license (in copyright) The development of halochromic textile materials could lead to interesting end-use applications as it offers the potential for flexible pH-sensors with a first warning signal.

However, sustained, profitable cotton production suffers increasing pressure from the competition of synthetic fibres. To remain competitive on the market, it is necessary to direct the research towards the breakthrough technologies that are propelling this ancient crop into the high-tech world of tomorrow. The selection of the novel fibre types with the best performance in an early stage of this development process is very crucial and requires new test methods that can score new traits on a large number of small volume fibre samples. Therefore, it is essential to develop new methods or adapt existing ones and optimise them to be applicable on a few grams of fibre material. In the scope of this research 2 main fibre properties were chosen as focus aspects namely reactivity/dye ability and flame retardancy. conference public C1 published published ugent Özgür Ceylan Özgür Ceylan aut author 002005040722 802000481295 972618734561 UGent Lieve Van Landuyt Lieve Van Landuyt aut author 801001285006 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Jennifer Tata Jennifer Tata aut author Jenny Alongi Jenny Alongi aut author Alberto Frache Alberto Frache aut author Alessandro Gigli Alessandro Gigli edt editor Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Stresa, Italy 2010-05-05 2010-05-07 9788896679005 Stresa, Italy Associazione Italiana di Chimica Tessile e Coloristica (AICTC) 2010 2010 Technology and Engineering CHARACTERISATION TECHNIQUES COTTON info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/947800/file/947801 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 290607 bytes C05_Ceylan_IFATCC_congress.pdf Ceylan, Özgür, Lieve Van Landuyt, Karen De Clerck, Jennifer Tata, Jenny Alongi, and Alberto Frache. 2010. “The Search for Superior Cotton Fibres of the Future: Novel Small Scale Tests Needed Today.” In IFATCC International Congress, 22nd, Proceedings, ed by.

This paper focuses on pH-sensitive or halochromic textile materials. Standard pH-indicator dyes were incorporated into different textile materials. Firstly, conventional textiles such as cotton and nylon were studied. Secondly, electrospun nano-nonwovens were investigated in which the dyes were added at the start of the production process. The results of the broad screening process showed the feasibility of dyeing cotton and nylon with pH-indicator dyes. In addition to this, electrospinning of polymer solutions with pH-indicator dyes was also achievable. The results prove the possibility of incorporating pH-indicator dyes into textiles. Moreover, the halochromic properties were retained in most of the studied textile systems. It was however noticed that the chromism of the dyes depended on the medium due to the dyefibre interactions. conference public C1 published published ugent Lien Van der Schueren Lien Van der Schueren aut author 002002166892 802000424715 UGent Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Alessandro Gigli Alessandro Gigli edt editor Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Stresa, Italy 2010-05-05 2010-05-07 9788896679005 Stresa, Italy Associazione Italiana di Chimica Tessile e Coloristica (AICTC) 2010 2010 Technology and Engineering NYLON PH-INDICATOR DYES COTTON HALOCHROMISM SENSOR info:eu-repo/semantics/restrictedAccess https://biblio.ugent.be/publication/947819/file/947820 info:eu-repo/semantics/restrictedAccess https://www.iana.org/assignments/media-types/application/pdf fullText http://purl.org/dc/dcmitype/Text 740672 bytes C06_VanderSchueren_IFATCC_congress.pdf Van der Schueren, Lien, and Karen De Clerck. 2010. “The Development of an Innovative PH-Sensor Based on Colour Changing Textiles.” In IFATCC International Congress, 22nd, Proceedings, ed by.

Temperature and humidity affect this process. In this article the influence of humidity and temperature on the formation and the properties of nanofibres are studied using cellulose acetate (CA) and poly(vinylpyrrolidone) (PVP) as target materials. The experiments indicate that two major parameters are dependent of temperature and have their influence on the average fibre diameter. A first parameter is the solvent evaporation rate that increases with increasing temperature. The second parameter is the viscosity of the polymer solution that decreases with increasing temperature. The trend in variation of the average nanofibre diameter as a function of humidity is different for CA and PVP, which can be explained by variations in chemical and molecular interaction and its influence on the solvent evaporation rate. As the humidity increases, the average fibre diameter of the CA nanofibres increases, whilst for PVP the average diameter decreases. The average diameter of nanofibres made by electrospinning change significantly through variation of temperature and humidity. journalArticle original public Article A1 published published ugent 8 Sander De Vrieze Sander De Vrieze aut author 802000062074 002001065843 TW11 Tamara Van Camp Tamara Van Camp aut author 801001940663 001998321046 UGent A.

A small scale laboratory method is developed to dye cotton with commercial dyes in vials. For the quantification of the dyeing levels of these small fibre samples, different techniques were adapted, such as UVVIS and Raman spectroscopy. The preferred method is dependent on the colour and the type of dye. conference public C1 published published ugent Özgür Ceylan Özgür Ceylan aut author 002005040722 802000481295 972618734561 UGent Lieve Van Landuyt Lieve Van Landuyt aut author 801001285006 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Izmir, Turkey 2009-05-26 2009-05-28 9754837872 Izmir, Turkey Ege University.

After a screening process in which the color depth, levelness and the color change properties of the dyed samples were examined, some dyes were selected to study in more detail. It was found that the behavior of the indicator dyes is different when the dyes are incorporated in textile materials instead of being dissolved in an aqueous solution. Our results show that it is possible to develop a textile pH-sensor using pH-indicators and conventional textiles. conference public C1 published published ugent Lien Van der Schueren Lien Van der Schueren aut author 002002166892 802000424715 UGent Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Paul Kiekens Paul Kiekens edt editor 973210305734 0000-0002-8280-2108 UGent Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Ghent, Belgium 2009-09-23 2009-09-25 9789081392426 Ghent, Belgium Ghent University.

The process exists at this moment 80 years and has seen a very turbulent history. There is a need to see what actually happened in this history. We have taken a brief look in the history of electrospinning. This paper is reporting on some of the aspects that electrospinning encountered. It is crucial to see that electrospinning has been used in different countries in different time periods. The history of electrospinning is mainly characterised by bad timing. The future of electrospinning looks however quit bright. conference public C1 published published ugent Sander De Vrieze Sander De Vrieze aut author 802000062074 002001065843 TW11 Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Paul Kiekens Paul Kiekens edt editor 973210305734 0000-0002-8280-2108 UGent Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department Ghent, Belgium 2009-09-23 2009-09-25 9789081392426 Ghent, Belgium Ghent University.

This cell is constructed of two electrodes planarly positioned against each other using a series of PVC plates. The obtained impedance, as a result of applied alternating potential and measured current signal, is equal to the resistance of the system electrode-electrolyte in the frequency region where no shift is observed in phase angle between applied potential and measured current. This resistance provides information about the properties and performance of the electrodes and a change of this resistance during the lifetime of the electrodes is an interesting parameter for quality control of the used electrodes. After characterization of the cell a range of textile electrodes (woven, non-woven and knitted) were investigated and compared. Results showed that the textile electrodes behave initially similar, obeying an equation that shows that the resistance is proportional to d, c(-1) and A(-2/3), d being the distance between the electrodes, c the electrolyte concentration and A the electrode surface. However, after longer exposure some indication of corrosion and malfunction was detected. journalArticle original public Article A1 published published ugent 7 Philippe Westbroek Philippe Westbroek aut author 801000885888 TW11 Georgios Priniotakis Georgios Priniotakis aut author 801001110002 TW11 Elina Palovuori Elina Palovuori aut author Karen De Clerck Karen De Clerck aut author 801000947425 976215851340 0000-0002-5650-3075 TW11 Lieva Van Langenhove Lieva Van Langenhove aut author 801000648543 972198930382 0000-0001-9802-7399 TW11 TW18 Paul Kiekens Paul Kiekens aut author 973210305734 0000-0002-8280-2108 UGent Department of Materials, Textiles and Chemical Engineering TW11 sht department Department of Textiles (ceased 1-2-2017) TW11* sht department 0040-5175 London, UK Sage Publications ltd 2006 76 2 152 159 2006 Technology and Engineering GARMENT MANUFACTURE INTELLIGENT TEXTILE Westbroek, Philippe, Georgios Priniotakis, Elina Palovuori, Karen De Clerck, Lieva Van Langenhove, and Paul Kiekens. 2006. “Quality Control of Textile Electrodes by Electrochemical Impedance Spectroscopy.” TEXTILE RESEARCH JOURNAL 76 (2): 152–159. doi:10.1177/0040517506053911.
