--- res: bibo_abstract: - Electrospinning can be used to create nanofibers from diverse polymers in which also other materials can be embedded. Inclusion of magnetic nanoparticles, for example, results in preparation of magnetic nanofibers which are usually isotropically distributed on the substrate. One method to create a preferred direction is using a spinning cylinder as the substrate, which is not always possible, especially in commercial electrospinning machines. Here, another simple technique to partly align magnetic nanofibers is investigated. Since electrospinning works in a strong electric field and the fibers thus carry charges when landing on the substrate, using partly conductive substrates leads to a current flow through the conductive parts of the substrate which, according to Ampère’s right-hand grip rule, creates a magnetic field around it. We observed that this magnetic field, on the other hand, can partly align magnetic nanofibers perpendicular to the borders of the current flow conductor. We report on the first observations of electrospinning magnetic nanofibers on partly conductive substrates with some of the conductive areas additionally being grounded, resulting in partly oriented magnetic nanofibers.@eng bibo_authorlist: - foaf_Person: foaf_givenName: Jan Lukas foaf_name: Storck, Jan Lukas foaf_surname: Storck foaf_workInfoHomepage: http://www.librecat.org/personId=221157 orcid: 0000-0002-6841-8791 orcid_put_code_url: https://api.orcid.org/v2.0/0000-0002-6841-8791/work/95037503 - foaf_Person: foaf_givenName: Timo foaf_name: Grothe, Timo foaf_surname: Grothe foaf_workInfoHomepage: http://www.librecat.org/personId=221330 orcid: 0000-0002-9099-4277 orcid_put_code_url: https://api.orcid.org/v2.0/0000-0002-9099-4277/work/94759559 - foaf_Person: foaf_givenName: Al foaf_name: Mamun, Al foaf_surname: Mamun - foaf_Person: foaf_givenName: Lilia foaf_name: Sabantina, Lilia foaf_surname: Sabantina - foaf_Person: foaf_givenName: Michaela foaf_name: Klöcker, Michaela foaf_surname: Klöcker - foaf_Person: foaf_givenName: Tomasz foaf_name: Blachowicz, Tomasz foaf_surname: Blachowicz - foaf_Person: foaf_givenName: Andrea foaf_name: Ehrmann, Andrea foaf_surname: Ehrmann foaf_workInfoHomepage: http://www.librecat.org/personId=223776 orcid: 0000-0003-0695-3905 orcid_put_code_url: https://api.orcid.org/v2.0/0000-0003-0695-3905/work/94763503 bibo_doi: 10.3390/ma13010047 bibo_issue: '1' bibo_volume: 13 dct_date: 2019^xs_gYear dct_isPartOf: - http://id.crossref.org/issn/1996-1944 dct_language: eng dct_subject: - electrospinning - magnetic nanofibers - magnetite - magnetic field lines - Ampère’s right-hand grip rule - Maxwell equations dct_title: Orientation of Electrospun Magnetic Nanofibers Near Conductive Areas@ ...
