20.500.12556/RUL-131814 Quasicrystalline ordering in thin liquid crystal films Quasicrystalline ordering was first observed in synthetic multi-component metallic alloys. These solid state materials exhibit quasicrystalline atomic ordering at nanometer length scales. Softmatter systems are another class of versatile materials that can exhibit quasicrystalline ordering across supra-nanometer (>10 nm) to supra-micrometer (>10 µm) length scales as recently observed in materials like-supramolecular dendritic molecules, ABC star polymers, binary nanoparticle systems and block co-polymers in condensed matter systems. The underlying mechanism in most of these soft quasicrystals seems to be the presence of two or more length scales in the system. Another class of development in self-assembled quasicrystals in softmatter is being observed in low molecular weight chiral and achiral nematic liquid crystals. Liquid crystal forms an efficient matrix for self- and directed-assemblies of colloidal structures where surface and geometry-tuning the particles in nematic liquid crystals gives rise to complex inter-particle interactions while the long-range order results in self-assembled structures of higher order rotational symmetries. Furthermore, there has also been attempts to generate colloidal quasicrystalline defect structures by directing the assemblies using multiple and single beam lasing techniques. In the present article, we will review self- and assisted-assembly of quasicrystalline structures in nematic liquid crystals (both chiral and achiral) and discuss the underlying mechanisms. liquid crystals quasi crystals self-assembly topological defects colloids nematic cholesteric optical manipulation tekoči kristali kvazikristali samourejanje topološki defekti koloidi true false true Angleški jezik Slovenski jezik Članek v reviji 2021-10-04 09:43:49 2021-10-04 09:43:50 2022-09-10 04:13:57 0000-00-00 00:00:00 2018 0 0 12 str. iss. 7, art. 275 Vol. 8 2018 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 538.9 2073-4352 10.3390/cryst8070275 3210340 RAZ_Dontabhaktuni_Jayasri_2018.pdf RAZ_Dontabhaktuni_Jayasri_2018.pdf 1 F176FA9C1AC77A3AE0799370EA4A7B02 b90f353256f3bf138cf601c07ba26067092966897b30761bb0ab5ccdf065141e 3397a67d-24eb-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=149232 https://www.mdpi.com/2073-4352/8/7/275 0 2bb334b1-24eb-11ec-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=149231 Fakulteta za matematiko in fiziko 0 0 0
