Marangoni instability in oblate droplets suspended on a circular frame
M. A. Shishkin, K. S. Kolegov, S. A. Pikin +2
We study theoretically internal flows in a small oblate droplet suspended on the circular frame. Marangoni convection arises due to a vertical temperature gradient across the drop…
Circulating Marangoni flows within droplets in smectic films
E. S. Pikina, M. A. Shishkin, K. S. Kolegov +2
We present theoretical study and numerical simulation of Marangoni convection within ellipsoidal isotropic droplets embedded in free standing smectic films (FSSF). The thermocapill…
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…
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…
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…
Analysis of the shape of x-ray diffraction peaks originating from the hexatic phase of liquid crystal films
I. A. Zaluzhnyy, R. P. Kurta, A. P. Menushenkov +2
X-ray diffraction studies of the bond-orientational order in the hexatic-B phase of 75OBC and 3(10)OBC compounds are presented. The temperature evolution of an angular profile of a…
Direct reconstruction of the two-dimensional pair distribution function in systems with angular correlations
I. A. Zaluzhnyy, R. P. Kurta, A. P. Menushenkov +2
An x-ray scattering approach to determine the two-dimensional (2D) pair distribution function (PDF) in partially ordered 2D systems is proposed. We derive relations between the str…
X-ray cross-correlation analysis of liquid crystal membranes in the vicinity of hexatic-smectic phase transition
R. P. Kurta, B. I. Ostrovskii, A. Singer +7
We present an x-ray study of liquid crystal membranes in the vicinity of hexatic-smectic phase transition by means of angular x-ray cross-correlation analysis (XCCA). By applying t…
