20.500.12556/RUL-173585 Biaxial structures of localized deformations and line-like distortions in effectively 2D nematic films We numerically studied localized elastic distortions in curved, effectively two-dimensional nematic shells. We used a mesoscopic Landau-de Gennes-type approach, in which the orientational order is theoretically considered by introducing the appropriate tensor nematic order parameter, while the three-dimensional shell shape is described by the curvature tensor. We limited our theoretical consideration to axially symmetric shapes of nematic shells. It was shown that in the surface regions of stomatocyte-class nematic shell shapes with large enough magnitudes of extrinsic (deviatoric) curvature, the direction of the in-plane orientational ordering can be mutually perpendicular above and below the narrow neck region. We demonstrate that such line-like nematic distortion configurations may run along the parallels (i.e., along the circular lines of constant latitude) located in the narrow neck regions of stomatocyte-like nematic shells. It was shown that nematic distortions are enabled by the order reconstruction mechanism. We propose that the regions of nematic shells that are strongly elastically deformed, i.e., topological defects and line-like distortions, may attract appropriately surface-decorated nanoparticles (NPs), which could potentially be useful for the controlled assembly of NPs. nematic shells orientational order topological defects stomatocytes order reconstruction mechanism nematične lupine orientacijski red topološki defekti stomatociti mehanizem rekonstrukcije orientacijskega reda true false true Angleški jezik Slovenski jezik Članek v reviji 2025-09-18 14:50:11 2025-09-18 14:50:17 2025-11-11 03:36:45 0000-00-00 00:00:00 2024 0 0 14 str. issue 3, art. 246 Vol. 14 Feb.-1 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 544.252.22 2079-4991 10.3390/nano14030246 183558659 nanomaterials-14-00246.pdf nanomaterials-14-00246.pdf 1 F10C2F9065563CA14F31C764B61A6D82 c9ec61d12810331c5215e3b026b3df43174d733c4183ab3590d5d40ef4c6e435 1776b78d-948e-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=218169 https://www.mdpi.com/2079-4991/14/3/246 1 e3a6135b-948d-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=218168 Fakulteta za elektrotehniko 0 0 0
