Angular structure factor of the hexatic-B liquid crystals: bridging theory and experiment
Ivan A. Zaluzhnyy, Ruslan P. Kurta, Michael Sprung +2
We report results from X-ray scattering studies of the angular structure factor of liquid crystal hexatic-B films. According to the sixfold rotational symmetry of the hexatic-B pha…
Femtosecond laser produced periodic plasma in a colloidal crystal probed by XFEL radiation
Nastasia Mukharamova, Sergey Lazarev, Janne-Mieke Meijer +20
With the rapid development of short-pulse intense laser sources, studies of matter under extreme irradiation conditions enter further unexplored regimes. In addition, an applicatio…
Angular x-ray cross-correlation analysis (AXCCA): Basic concepts and recent applications to soft matter and nanomaterials
Ivan A. Zaluzhnyy, Ruslan P. Kurta, Marcus Scheele +3
Angular x-ray cross-correlation analysis (AXCCA) is a technique which allows quantitative measurement of the angular anisotropy of x-ray diffraction patterns and provides insights…
Unravelling structural rearrangement of polymer colloidal crystals under dry sintering conditions
Alexey V. Zozulya, Ivan A. Zaluzhnyy, Nastasia Mukharamova +7
Structural rearrangement of polystyrene colloidal crystals under dry sintering conditions has been revealed by in situ grazing incidence X-ray scattering. Measured diffraction patt…
Evidence of a first-order smectic -- hexatic transition and its proximity to tricritical point in smectic films
Ivan A. Zaluzhnyy, Ruslan P. Kurta, Nastasia Mukharamova +10
Experimental and theoretical studies of a smectic-hexatic transition in freely suspended films of 54COOBC compound are presented. X-ray investigations revealed a discontinuous firs…
Structural studies of the bond-orientational order and hexatic-smectic transition in liquid crystals of various compositions
I. A. Zaluzhnyy, R. P. Kurta, E. A. Sulyanova +9
We report on X-ray studies of freely suspended hexatic films of three different liquid crystal compounds. By applying angular X-ray cross-correlation analysis (XCCA) to the measure…
