Lateral disorder in Langmuir monolayers: theoretical derivations and grazing-incidence X-ray diffraction
L. R. Muftakhova, K. V. Nikolaev, A. V. Rogachev +3
Recent studies of the self-assembly of Langmuir monolayers have revealed novel forms of lateral molecular ordering. Such studies typically involve the use of grazing-incidence sync…
Conical diffraction of the synchrotron beam to probe the efficiency and morphology of blazed gratings
K. V. Nikolaev, L. I. Goray, P. S. Savchenkov +8
This study explores the use of synchrotron measurements as a nanometrology tool for blazed gratings. In grazing incidence geometry, one can measure both the conical diffraction and…
X-ray diffraction from smectic multilayers: crossover from kinematical to dynamical regime
V. V. Samsonov, K. V. Nikolaev, B. I. Ostrovskii +1
We study X-ray diffraction in smectic liquid crystal multilayers. Such systems are fabricated as freely suspended films and have a unique layered structure. As such, they can be de…
Probing Langmuir monolayer self-assembly in condensed and collapsed phases: grazing incidence X-ray diffraction and X-ray standing waves studies
K. V. Nikolaev, L. R. Muftakhova, G. M. Kuzmicheva +4
Ce-induced effects on the self-assembly of arachidic acid Langmuir monolayers was studied in this work. The monolayers were formed on the liquid subphase in the presence of Ce(III)…
Multimodal reconstruction of TbCo thin film structure with Basyeian analysis of polarised neutron reflectivity
P. S. Savchenkov, K. V. Nikolaev, V. I. Bodnarchuk +3
We implemented the Bayesian analysis to the polarised neutron reflectivity data. Reflectivity data from a magnetic TbCo thin film structure was studied using the bundle of a Monte-…
