20.500.12556/DKUM-89111 Unmasking the structure of a chiral cubic thermotropic liquid crystal phase by a combination of soft and tender resonant X-ray scattering A resonant X-ray scattering response for two structural models of a chiral cubic phase with a giant unit cell, one composed of a continuous grid and micelles and the other with three continuous grids, is studied theoretically and compared to experimental measurements. For both structural models resonant enhancement of all the symmetry-allowed diffraction peaks is predicted, as well as the existance of several symmetry forbidden peaks (pure resonant peaks). Experimental measurements were performed at the carbon and sulphur absorption edge. Only one pure resonant peak was observed, which is predicted by both models. Two low-angle symmetry allowed peaks, not observed in non-resonant scattering, were resonantly enhanced and their intensity angular dependence can distinguish between the two structural models. resonant X-ray scattering chiral cubic thermotropic liquid crystal phase structural models carbon absorption edge sulphur absorption edge resonančno rentgensko sipanje kiralna kubična termotropna tekoča kristalna faza strukturni modeli absorpcijski rob ogljika absorpcijski rob žvepla true false true Royal Society of Chemistry Angleški jezik Slovenski jezik Znanstveno delo 2024-06-13 14:28:53 2024-06-13 14:43:55 2024-06-14 03:25:14 0000-00-00 00:00:00 2022 0 0 Str. 8194-8200 Št. 42 Letn. 18 Nov. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2022-07-31 2022-10-15 2022-10-17 53 127668483 10.1039/d2sm01030e 1744-6848 Grabovac-2022-Unmasking_the_structure_of_a_chi.pdf Grabovac-2022-Unmasking_the_structure_of_a_chi.pdf 1 151CF2F5454F4DAE4FC7AF120761C949 9d4b15300356c17a18b990274ba14f823dde31f34638312a9780123a0a64a350 69d2f2d4-2982-11ef-9d59-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=180519 https://doi.org/10.1039/D2SM01030E 0 7dfb630d-2982-11ef-9d59-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=180520 Fakulteta za naravoslovje in matematiko 0 0 0
