20.500.12556/DKUM-60177 Impact of nanoparticles on nematic ordering in square wells Nematic liquid crystalline structures within square wells are studied numerically using both Lebwohl-Lasher lattice semimicroscopic and the Landau-de Gennes mesoscopic approach. At lateral boundary wall strong planar anchoring is enforced. The cell thickness h along the z Cartesian coordinate is assumed to be smaller than the characteristic square well size R. Using semimicroscopic modelling we restrict to effectively two-dimensional systems which we study in terms of the tensor nematic order parameter. We consider impact of appropriate nanoparticles (NPs) on nematic configuration for cases where R becomes comparable to the biaxial order parameter correlation length. In this case a star-like order reconstruction biaxial profile could be formed in absence of NPs. We demonstrate existence of a rich variety of different nematic structures, including topological defects, which are enabled by presence of appropriate NPs. liquid crystals nanoparticles nematic ordering square well software simulation visualization tekoči kristali nano delci nematična urejenost kvadratna kletka simulacije grafični prikaz true true true Angleški jezik Slovenski jezik Znanstveno delo 2016-06-09 03:15:52 2017-06-14 09:35:40 2022-06-22 03:06:09 2019-07-11 11:37:52 2015 0 0 str. 1-11 Letn. 2015 2015 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1687-8108 532.783 23812647 21186312 10.1155/2015/532745 1687-8108 URN:SI:UM:DK:JARITKUL Advances_in_Condensed_Matter_Physics_2015_Slavinec_et_al._Impact_of_Nanoparticles_on_Nematic_Ordering_in_Square_Wells.pdf Advances_in_Condensed_Matter_Physics_2015_Slavinec_et_al._Impact_of_Nanoparticles_on_Nematic_Ordering_in_Square_Wells.pdf 1 5F989FDCA74A8A62316934D5E5BAAEE4 bb600ec40670eb2c78a6f4a7b1c525b5e464a74974d89ad6c33c426eb7b4cb77 3d2593b8-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=112483 http://www.hindawi.com/journals/acmp/2015/532745/ 1 https://dk.um.si/Dokument.php?lang=slv&id=93992 Fakulteta za naravoslovje in matematiko 0 0 0
