Especially nanofiber mats from biopolymers promote cell growth for wound healing, tis-sue engineering or other biotechnological applications. These materials, however, are often not stable at high temperatures, which makes sterilization challenging. The paper discusses sterilization methods, a comparison of different biopolymer blends for cell growth, and the influence of vacuum ultraviolet irradia-tion (VUV) and plasma treatment on cell growth and adhesion on electrospun nanofiber mats. This mini-review thus serves as a base for researchers working on the improvement of nanofiber mats for mammalian cell growth, giving some general ideas as well as interesting special findings.","lang":"eng"}],"status":"public","editor":[{"last_name":"Guxho","full_name":"Guxho, Genti","first_name":"Genti"},{"full_name":"Kosova Spahiu, Tatjana","first_name":"Tatjana","last_name":"Kosova Spahiu"},{"full_name":"Prifti, Valma","first_name":"Valma","last_name":"Prifti"},{"last_name":"Gjeta","first_name":"Ardit","full_name":"Gjeta, Ardit"},{"first_name":"Eralda","full_name":"Xhafka, Eralda","last_name":"Xhafka"},{"last_name":"Sulejmani","first_name":"Anis","full_name":"Sulejmani, Anis"}],"project":[{"_id":"0ec202b7-cd76-11ed-89f4-a9e1a6dbdaa7","name":"Institut für Technische Energie-Systeme"}],"doi":"10.1007/978-3-031-48933-4_51","citation":{"short":"A.

For these purposes, different physical, thermochemical, and biochemical properties are necessary, which are discussed within this review, such as porosity, high temperature resistance, or good mechanical properties for batteries and high energy density and abundance of the base materials in case of biofuel, along with the environmental aspects of using algae-based biopolymers in these applications. On the other hand, bacterial biopolymers are also often used in batteries as bacterial cellulose separators or as biopolymer network binders, besides their potential use as polymer electrolytes. In addition, they are also regarded as potential sustainable biofuel producers and converters. This review aims at comparing biopolymers from both aforementioned sources for energy conversion and storage. Challenges regarding the production of algal biopolymers include low scalability and low cost-effectiveness, and for bacterial polymers, slow growth rates and non-optimal fermentation processes often cause challenges. On the other hand, environmental benefits in comparison with conventional polymers and the better biodegradability are large advantages of these biopolymers, which suggest further research to make their production more economical.

In our study, they were grown on different titanium substrates, comparing commercially available titanium sheets of grade 1 and grade 2, respectively, with Ti64 which was 3D printed with different porosity in order to identify potential substitutes for common well-plates, which could – in case of 3D printed substrates – be produced in various shapes and dimensions and thus broaden the range of substrates for cell growth in biotechnology and tissue engineering. In addition, thin layers of poly(acrylonitrile) (PAN) nanofibers were electrospun on these substrates to add a nanostructure. The common titanium sheets showed lower cell cover factors than common well plates, which could not be improved by the thin nanofibrous coating. However, the Ti sheets with nanofiber mat coatings showed higher cell adhesion and proliferation than pure PAN nanofiber mats. The 3D printed Ti64 substrates prepared by laser metal fusion, on the other hand, enabled significantly higher proliferation of (66 ± 8)% cover factor after three days of cell growth than well plates which are usually applied as the gold standard for cell cultivation ((48 ± 11)% cover factor under identical conditions). Especially the Ti64 samples with higher porosity showed high cell adhesion and proliferation.

In many material systems, the EB field is reduced from one hysteresis loop to the next measurement. This so‐called training effect (TE) has been investigated in experiments and by means of theoretical efforts by many research groups. The reduction of the EB field as a result of subsequent magnetization reversal processes is often fitted by a power law, usually with the exception of n = 1, or with an equation based on the discretized Landau–Khalatnikov equation, as first suggested by Binek. Few other models, usually with more fitting parameters, have been proposed yet. Herein, it is shown that for large numbers of subsequent magnetization reversal processes in Co/CoO thin film samples, a modified power law or a logarithmic fit can model the TE in most cases as well as the abovementioned, commonly used models.

Here, we demonstrate a large EB of over 1000 Oe at 20 K in a twinned Co(111)/Co3O4(111) thin film epitaxially grown on sapphire(0001) with sixfold rotational lattice symmetry, which is among the highest values reported for Co/Co1−yO systems. In such systems, the effect intensity is largest along the magnetic easy axes, which usually results in an anisotropy of the EB in epitaxial interfaces. However, we observed identical EB values for 0°, 15°, and 30° angles between the magnetic field and the nearest Co[002] magnetic easy axes. The measurements imply a relaxation of the magnetization to the nearest easy axis, suggesting increasingly isotropic EB fields with higher orders of rotational lattice symmetry.\r\n ","lang":"eng"}],"status":"public","file_date_updated":"2023-12-29T07:53:14Z","has_accepted_license":"1","publication_status":"published","author":[{"full_name":"Wortmann, Martin","first_name":"Martin","last_name":"Wortmann"},{"first_name":"Tapas","full_name":"Samanta, Tapas","last_name":"Samanta"},{"first_name":"Maik","full_name":"Gaerner, Maik","last_name":"Gaerner"},{"full_name":"Westphal, Michael","first_name":"Michael","last_name":"Westphal"},{"full_name":"Fiedler, Johannes","first_name":"Johannes","last_name":"Fiedler"},{"last_name":"Ennen","first_name":"Inga","full_name":"Ennen, Inga"},{"full_name":"Hütten, Andreas","first_name":"Andreas","last_name":"Hütten"},{"last_name":"Blachowicz","first_name":"Tomasz","full_name":"Blachowicz, Tomasz"},{"full_name":"Caron, Luana","first_name":"Luana","last_name":"Caron"},{"id":"223776","orcid":"0000-0003-0695-3905","first_name":"Andrea","full_name":"Ehrmann, Andrea","last_name":"Ehrmann"}],"publication_identifier":{"eissn":["2166-532X"]},"doi":"10.1063/5.0183566","keyword":["Magnetic ordering","Crystallographic defects","Electron diffraction","Epitaxy","Ferromagnetic materials","Magnetic hysteresis","Magnetic materials","Thin films","Transmission electron microscopy","Solid solid interfaces"],"year":"2023","main_file_link":[{"open_access":"1"}],"funded_apc":"1","user_id":"220548","volume":11,"publisher":"AIP Publishing","date_updated":"2024-01-29T16:36:10Z"},{"main_file_link":[{"url":"https://mdpi-res.com/bookfiles/book/8445/3D_Printing_of_MEMS_Technology.pdf?v=1702887078","open_access":"1"}],"place":"Basel","year":"2023","keyword":["3D printed nanostructures and nano-composites for application in MEMS","Lab-on-a-chip devices","Microfluidics","Microelectronics","Micro-batteries and other energy storage devices","Micro- and nano-sensors and -actuators (physical","chemical","biological)","Challenges and possible solutions of using 3D printing technologies for MEMS","Similar approaches related to 3D printing of MEMS technology"],"quality_controlled":"1","tmp":{"short":"CC BY-NC-ND (4.0)","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","image":"/images/cc_by_nc_nd.png","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)"},"oa":"1","type":"book_editor","publisher":"MDPI","user_id":"231260","date_updated":"2023-12-18T08:13:55Z","editor":[{"id":"223776","orcid":"0000-0003-0695-3905","last_name":"Ehrmann","first_name":"Andrea","full_name":"Ehrmann, Andrea"}],"status":"public","abstract":[{"text":"Three-dimensional printing is among the emerging technologies of our time.

Various high-resolution microscopy techniques are used for morphological investigations, with the diameter as primary characteristic. Since methodological factors influencing the diameter distribution are usually ignored, numerical values can hardly be compared across different or even within single studies. Here, we investigate influencing factors such as microscopy technique, degree of magnification, eventual coatings, and the analysts' bias in the image selection and evaluation. We imaged a single nanofiber sample using scanning electron microscopy (SEM), helium ion microscopy (HIM), atomic force microscopy (AFM), and transmission electron microscopy (TEM). These techniques yield significant methodological variations between the diameter distributions. We further observed a strong influence of analysts' subjectivity, with a consistent average deviation between 4 different analysts of up to 31%. The average deviation between micrographs within each category was 14%, revealing a considerable influence of micrograph selection and strong potential for cherry picking. The mean values were mostly comparable with the results using automated image analysis software, which was more reproducible, much faster, and more accurate for images with lower magnification. The results demonstrate that one of the most frequently measured characteristics of nanofibers is subject to strong systematic fluctuations that are rarely if ever addressed.\r\n "}],"status":"public","publication_status":"published","has_accepted_license":"1","file_date_updated":"2023-11-25T11:02:42Z"},{"publication":"Polymers","issue":"19","article_type":"original","intvolume":" 15","type":"journal_article","oa":"1","quality_controlled":"1","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png"},"file":[{"date_created":"2023-11-25T11:04:17Z","success":1,"creator":"aehrmann","relation":"main_file","content_type":"application/pdf","file_size":5916920,"date_updated":"2023-11-25T11:04:17Z","file_name":"_2023_Heide-Wiebe_Polymers15_3951_v2.pdf","file_id":"3752","access_level":"open_access"}],"citation":{"mla":"Heide, Angela, et al. “Suitability of Mycelium-Reinforced Nanofiber Mats for Filtration of Different Dyes.” Polymers, vol. 15, no. 19, 3951, MDPI AG, 2023, doi:10.3390/polym15193951.","ama":"Heide A, Wiebe P, Sabantina L, Ehrmann A.

They are thus highly suitable as filters for small particles and molecules, such as organic dyes. On the other hand, they are usually very thin and thus have low mechanical properties. As a potential reinforcement, mycelium of Pleurotus ostreatus was grown on poly(acrylonitrile) nanofiber mats and thermally solidified after fully covering the nanofiber mats. This study investigates whether the filtration efficiency of the nanofiber mats is altered by the mycelium growing through it and whether the mechanical properties of the nanofibrous filters can be improved in this way. The study shows fast and reliable growth of the mycelium on the nanofiber mats and high filtration efficiency for astra blue and chlorophyll, while indigo carmine showed only very low filtration efficiency of up to 20%. For chlorophyll and safranin, membranes with mycelium showed higher filtration than pure nanofiber mats. In diffusion cell tests, especially astra blue was strongly adsorbed on the membranes with mycelium.\r\n "}],"file_date_updated":"2023-11-25T11:04:17Z","publication_status":"published","has_accepted_license":"1"},{"title":"Adhesion and Stab-resistant Properties of FDM-printed Polymer/Textile Composites","date_created":"2023-11-25T11:07:18Z","file_date_updated":"2023-11-25T11:06:49Z","has_accepted_license":"1","_id":"3755","publication_status":"published","status":"public","abstract":[{"text":" Stab-resistant clothing has been used for centuries by soldiers.

In practice, rigid EMI shields are the most commonly used ones. However, for humans or in automotive and aviation applications, flexible, drapable materials, such as textile fabrics, can be more effective and useful. Textile fabrics are usually nonconductive and not magnetic, i.e., they lack the requirements for EMI shielding. However, shielding properties of textile fabrics can be achieved by blending yarns with fine wires or coating fibers or by blending complete textile layers with conductive or magnetic materials. In this paper, shielding textile fabrics and 3D-printed materials, as references with different conductive (and partly also magnetic) properties, are examined. The measurements show a high shielding effectiveness of 80 dB given by densely woven fabrics with a thin metallic coating in the frequency range of 6.5–11 GHz, while large pores in crocheted fabrics significantly reduce the EMI shielding effectiveness, and other samples did not show shielding at all, suggesting that a combination of conductivity and the structure of the samples is responsible for the shielding potential.\r\n ","lang":"eng"}],"has_accepted_license":"1","publication_status":"published","file_date_updated":"2023-11-25T11:09:10Z","article_number":"9777","author":[{"full_name":"Wójcik, Dariusz","first_name":"Dariusz","last_name":"Wójcik"},{"last_name":"Surma","full_name":"Surma, Maciej","first_name":"Maciej"},{"last_name":"Magnuski","full_name":"Magnuski, Mirosław","first_name":"Mirosław"},{"full_name":"Blachowicz, Tomasz","first_name":"Tomasz","last_name":"Blachowicz"},{"id":"222971","full_name":"Tuvshinbayar, Khorolsuren","first_name":"Khorolsuren","last_name":"Tuvshinbayar"},{"last_name":"Dotter","full_name":"Dotter, Marius","first_name":"Marius","orcid":"0000-0001-8398-1809","id":"242889"},{"first_name":"Yusuf","full_name":"Topuz, Yusuf","last_name":"Topuz"},{"last_name":"Ehrmann","full_name":"Ehrmann, Andrea","first_name":"Andrea","orcid":"0000-0003-0695-3905","id":"223776"}],"publication_identifier":{"eissn":["2076-3417"]},"doi":"10.3390/app13179777","intvolume":" 13","quality_controlled":"1","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png"},"oa":"1","type":"journal_article","publication":"Applied Sciences","article_type":"original","issue":"17","_id":"3758","date_created":"2023-11-25T11:09:44Z","title":"Experimental Verification of the Shielding Properties of Selected Textile Materials in the X Frequency Band","file":[{"file_name":"_2023_Wojcik_ApplSci13_9777_v2.pdf","access_level":"open_access","file_id":"3759","content_type":"application/pdf","file_size":54523499,"date_updated":"2023-11-25T11:09:10Z","relation":"main_file","success":1,"creator":"aehrmann","date_created":"2023-11-25T11:09:10Z"}],"language":[{"iso":"eng"}],"citation":{"short":"D.

While common Ag/AgCl glued gel electrodes enable good electrode skin contact, even during movements, they are not comfortable and can irritate the skin during long-term measurements. A possible alternative is textile electrodes, which have been investigated extensively during the last years. These electrodes, however, are usually not able to provide reliable, constant skin contact, resulting in reduced signal quality. Another important problem is the modification of the electrode surface due to washing or abrasion, which may impede the long-term use of such textile electrodes. Here, we report a study of washing and abrasion resistance of different ECG electrodes based on an isolating woven fabric with conductive embroidery and two conductive coatings, showing unexpectedly high abrasion resistance of the silver-coated yarn and optimum ECG signal quality for an additional coating with a conductive silicone rubber. Sheet resistances of the as-prepared electrodes were in the range of 20–30 Ω, which was increased to the range of 25–40 Ω after five washing cycles and up to approximately 50 Ω after Martindale abrasion tests. ECG measurements during different movements revealed reduced motion artifacts for the electrodes with conductive silicone rubber as compared to glued electrodes, suggesting that electronic filtering of such noise may even be easier for textile electrodes than for commercial electrodes.\r\n ","lang":"eng"}],"doi":"10.3390/coatings13091624","article_number":"1624","author":[{"first_name":"Dajana","full_name":"Doci, Dajana","last_name":"Doci"},{"first_name":"Melisa","full_name":"Ademi, Melisa","last_name":"Ademi"},{"first_name":"Khorolsuren","full_name":"Tuvshinbayar, Khorolsuren","last_name":"Tuvshinbayar","id":"222971"},{"last_name":"Richter","first_name":"Niclas","full_name":"Richter, Niclas","id":"224900","orcid":"0000-0002-8980-0957"},{"last_name":"Ehrmann","first_name":"Guido","full_name":"Ehrmann, Guido"},{"first_name":"Tatjana","full_name":"Spahiu, Tatjana","last_name":"Spahiu"},{"orcid":"0000-0003-0695-3905","id":"223776","last_name":"Ehrmann","full_name":"Ehrmann, Andrea","first_name":"Andrea"}],"publication_identifier":{"eissn":["2079-6412"]},"oa":"1","type":"journal_article","quality_controlled":"1","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png"},"intvolume":" 13","issue":"9","article_type":"original","publication":"Coatings","date_created":"2023-11-25T11:06:05Z","title":"Washing and Abrasion Resistance of Textile Electrodes for ECG Measurements","_id":"3753","citation":{"ieee":"D.

However, the knowledge on crocheted fabrics is very scarce and only few technical applications are presented in the literature. To provide a basis for possible future technical applications, the general tensile properties of crocheted fabrics are explored, and a promising application as composite reinforcement is introduced. Due to the early development state of the crochet machine prototype, conventionally hand-made crocheted fabrics are studied and the benefit of improving the machine is evaluated. The mechanical properties of crocheted fabrics depend significantly on the individual crocheter, but fabrics produced from the same person are sufficiently reproducible for reasonable investigations. Anisotropic properties with a trend toward higher resisted forces in course compared to wale direction were identified with crochets constructed from single crochet (sc) and from half double crochet (hdc) stitches. Furthermore, a tendency toward higher possible loads at larger elongations was revealed for crocheted fabrics compared to knitted ones. To the best of our knowledge, for the first time crocheted aramid fabrics were used in epoxy composites. With a crocheted reinforcement in a non-cut composite produced by vacuum-assisted hand lay-up, significantly higher ultimate tensile strength and Young’s modulus were recorded compared to a knitted one with comparable fracture modes.\r\n ","lang":"eng"}],"date_updated":"2023-12-04T09:18:36Z","article_type":"original","volume":18,"publisher":"SAGE Publications","user_id":"220548","publication":"Journal of Engineered Fibers and Fabrics","quality_controlled":"1","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png"},"funded_apc":"1","oa":"1","type":"journal_article","intvolume":" 18","main_file_link":[{"open_access":"1","url":"https://journals.sagepub.com/doi/10.1177/15589250231203381"}],"year":"2023"},{"issue":"18","date_updated":"2023-09-18T07:43:15Z","article_type":"original","volume":13,"publisher":"MDPI AG","user_id":"245590","publication":"Nanomaterials","type":"journal_article","oa":"1","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png"},"year":"2023","intvolume":" 13","main_file_link":[{"url":"https://doi.org/10.3390/nano13182507","open_access":"1"}],"citation":{"ama":"Morina E, Dotter M, Döpke C, Kola I, Spahiu T, Ehrmann A.

The latter allow for producing large-area nanofiber mats, e.g., with a width of 50 cm and lengths of several meters, if electrospinning proceeds for several hours, depending on the required thickness. Even spinning smaller samples, however, raises the question of homogeneity, especially if defined mechanical properties or a defined thickness is required, e.g., for filtration purposes. Very often, only the inner parts of such electrospun nanofiber mats are used to avoid too high variation of the nanofiber mat thickness. For this study, we used wire-based electrospinning to prepare nanofiber mats with slightly varying spinning parameters. We report investigations of the thickness and mass per unit area, measured on different positions of needleless electrospun nanofiber mats. Martindale abrasion tests on different positions are added as a measure of the mechanical properties. All nanofiber mats show unexpectedly strong variations of thickness, mass per unit area, and porosity, as calculated from the apparent density of the membranes. The thickness especially varied by nearly one order of magnitude within one sample, while the apparent density, as the most uniform parameter, still showed variations by more than a factor of two within one sample. This shows that even for apparently highly homogeneous areas of such nanofiber mats, variations cannot be neglected for all potential applications.\r\n "}]}]
