20.500.12556/DKUM-60191 Controlled nanoparticle targeting and nanoparticle-driven nematic structural transition We study experimentally and theoretically controlled targeting of specific nanoparticles (NPs) to different regions within nematic liquid crystal. Using a simple mesoscopic Landau-de Gennes-type model in terms of a tensor nematic order parameter, we demonstrate a general mechanism which could be exploited for controlled targeting of NPs within a spatially nonhomogeneous nematic texture. Furthermore, we experimentally demonstrate using polarising microscopy that even a relatively low concentration of localised appropriate NPs could trigger a nematic structural transition. A simple estimate is derived to account for the observed transition. liquid crystals nanoparticles structural transitions tekoči kristali nanodelci strukturni prehodi true true true Angleški jezik Slovenski jezik Članek v reviji 2016-06-09 03:16:09 2017-06-14 08:45:02 2024-03-27 09:16:28 2019-07-11 11:38:20 2015 0 0 str. 1-9 Letn. 2015 2015 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1687-8108 532.783 23812647 21848584 10.1155/2015/803480 1687-8108 URN:SI:UM:DK:3XGCF3SE Advances_in_Condensed_Matter_Physics_2015_Dubtsov_et_al._Controlled_Nanoparticle_Targeting_and_Nanoparticle-Driven_Nematic_Structural_Tr.pdf Advances_in_Condensed_Matter_Physics_2015_Dubtsov_et_al._Controlled_Nanoparticle_Targeting_and_Nanoparticle-Driven_Nematic_Structural_Tr.pdf 1 9807FF8EB1FE6931AD2AA4F438B05AAB 166a6b0dbf8094e913154cfc8ed04abe16c6c64118260662f689cd7420ac36d8 3ccd1105-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=112472 http://www.hindawi.com/journals/acmp/2015/803480/ 1 https://dk.um.si/Dokument.php?lang=slv&id=112471 Fakulteta za naravoslovje in matematiko 0 0 0
