20.500.12556/DKUM-67137 Symmetry breaking and structure of a mixture of nematic liquid crystals and anisotropic nanoparticles Orientational ordering of a homogeneous mixture of uniaxial liquid crystalline(LC) molecules and magnetic nanoparticles (NPs) is studied using the Lebwohl-Lasher lattice model. We consider cases where NPs tend to be oriented perpendicularly to LC molecules due to elastic forces. We study domain-type configurations of ensembles, which are quenched from the isotropic phase. We show that for large enough concentrations of NPs the long range uniaxial nematic ordering is replaced by short range order exhibiting strong biaxiality. This suggests that the impact of NPs on orientational ordering of LCs for appropriate concentrations of NPs is reminiscent to the influence of quenched random fields which locally enforce a biaxial ordering. liquid crystals nanoparticles disorder orientational order quenched disorder symmetry breaking tekoči kristali nanodelci nered. orientacijski red true true true Beilstein-Institut Angleški jezik Slovenski jezik Znanstveno delo 2017-08-03 10:58:27 2017-08-03 10:59:11 2026-09-02 12:59:29 2019-07-11 16:10:14 2010 0 0 str. 1-7 št. 74 Letn. 6 2010 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2010-03-11 2010-06-11 2010-07-07 Y506-6603 620.1/.2 17406984 17869320 10.3762/bjoc.6.74 Y506-6603 URN:SI:UM:DK:IR9M0X91 Beilstein_Journal_of_Organic_Chemistry_2010_Krasna,_Cvetko,_Ambrozic_Symmetry_breaking_and_structure_of_a_mixture_of_nematic_liquid_crys.pdf Beilstein_Journal_of_Organic_Chemistry_2010_Krasna,_Cvetko,_Ambrozic_Symmetry_breaking_and_structure_of_a_mixture_of_nematic_liquid_crys.pdf 1 74F33741BAB5622A716A6EA2DC2674BF 8d42c8bf24627b2fdbbdb453fdb6aa15f04fd4f1ceb9beaf82fbffcc46cb4c19 78ecfac1-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/b938c95c-7d87-4485-b88d-fd4b5bfcec48 https://dk.um.si/Dokument.php?lang=slv&id=114789 http://www.beilstein-journals.org/bjoc/articles/6/74 1 https://dk.um.si/Dokument.php?lang=slv&id=114788 Fakulteta za naravoslovje in matematiko 0 0 0
