20.500.12556/DKUM-89752 Experimental advances in nanoparticle-driven stabilization of liquid-crystalline blue phases and twist-grain boundary phases Recent advances in experimental studies of nanoparticle-driven stabilization of chiral liquid-crystalline phases are highlighted. The stabilization is achieved via the nanoparticles’ assembly in the defect lattices of the soft liquid-crystalline hosts. This is of significant importance for understanding the interactions of nanoparticles with topological defects and for envisioned technological applications. We demonstrate that blue phases are stabilized and twist-grain boundary phases are induced by dispersing surface-functionalized CdSSe quantum dots, spherical Au nanoparticles, as well as MoS2 nanoplatelets and reduced-graphene oxide nanosheets in chiral liquid crystals. Phase diagrams are shown based on calorimetric and optical measurements. Our findings related to the role of the nanoparticle core composition, size, shape, and surface coating on the stabilization effect are presented, followed by an overview of and comparison with other related studies in the literature. Moreover, the key points of the underlying mechanisms are summarized and prospects in the field are briefly discussed. liquid crystals nanoparticles quantum dots reduced-graphene oxide calorimetry microscopy blue phases twist-grain boundary phases disclination lines screw dislocations tekoči kristali nanodelci kvantne pike reducirani grafen oksid kalorimetrija mikroskopija modre faze faze na meji med zasukom in zrnom dislokacijske linije vijačne dislokacije true true true MDPI Angleški jezik Slovenski jezik Članek v reviji 2024-08-09 12:14:43 2024-08-09 12:35:22 2024-08-14 08:48:43 0000-00-00 00:00:00 2021 0 0 Str. 1-19 Št. 11, št. članka 2968 Letn. 11 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2021-10-07 2021-11-03 2021-11-05 53 83680771 10.3390/nano11112968 2079-4991 Cordoyiannis-2021-Experimental_Advances_in_Nan.pdf Cordoyiannis-2021-Experimental_Advances_in_Nan.pdf 1 4D5ACF228352B94BBA76A77E2DCE8FDF 80a1dbf198d9120a160126e343872f8257273106eab4eaeec2ecdf5f4bcc46eb e5953b6a-563a-11ef-97b6-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=182183 https://doi.org/10.3390/nano11112968 0 f292862a-563a-11ef-97b6-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=182184 Fakulteta za naravoslovje in matematiko 0 0 0
