20.500.12556/RUL-133683 Interactions on the interface between two liquid crystal materials In liquid crystal applications, boundary conditions are essential to ensuring suitable bulk molecular orientation and a deterministic response to external fields. Be it confinement to a droplet or a shell, a glass plate, or an interface with air or another liquid, proper surface alignment must be ensured—mechanically by rubbing, by chemical treatment that adds a layer of aligning molecules, by using photoalignment or even by leaving the surface untreated, using the intrinsic properties of the substrate itself. The anchoring can be classified as unidirectional (perpendicular homeotropic, or at oblique angles), or degenerate (planar or pre-tilted). However, if both substances at the interface are anisotropic, more diverse behaviour is expected. Here, we present a numerical simulation of a nematic droplet in a nematic host, and investigate behaviour of the director field and defects at the interface for different interfacial couplings. Finally, we compare the simulations to experimental images of discotic droplets in a calamitic nematic host. liquid crystals surface anchoring nematic droplets numerical simulations anisotropic interface Landau-de Gennes tekoči kristali površinsko sidranje nematske kapljice numerične simulacije true false true Angleški jezik Slovenski jezik Članek v reviji 2021-12-09 09:01:20 2021-12-09 09:01:22 2022-09-13 03:52:04 0000-00-00 00:00:00 2020 0 0 10 str. iss. 5, art. 393 Vol. 10 May 2020 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 538.9 2073-4352 10.3390/cryst10050393 15849731 RAZ_Gersak_Rok_2020.pdf RAZ_Gersak_Rok_2020.pdf 1 7ED183EE50B871DF1ADEF1D44194D0CB 7ca1ca90f69020b9a31ef81cc21d7b0a2bd012b573927f96667472d423dff664 62224e27-58c6-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=151954 https://www.mdpi.com/2073-4352/10/5/393 0 55171c52-58c6-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=151953 Fakulteta za matematiko in fiziko 0 0 0
