Int3D: A Data Reduction Software for Single Crystal Neutron Diffraction

open access: yesCrystals, 2021
We describe a new software package for the data reduction of single crystal neutron diffraction using large 2D detectors. The software consists of a graphical user interface from which the user can visualize, interact with and process the data.

Axial-Symmetric Diffraction Radiation Antenna with a Very Narrow Funnel-Shaped Directional Diagram

open access: yesApplied Sciences, 2021
The paper is focused on reliable modeling and analysis of axially symmetric radiators with a very narrow (throat) funnel-shaped radiation pattern. When such a diagram is formed, a wave analogue of Smith–Purcell coherent radiation is realized—the surface ...

Diffraction in grating optical filters with angular-selective light transmission [PDF]

open access: yesКомпьютерная оптика, 2020
The effect of diffraction on the directional light transmittance of grating optical filters designed for smart windows is studied. The filter has an angular selective light transmission due to two thin-film gratings formed by "non-transmissive ...

Incommensurate structures of the [CH3NH3][Co(COOH)3] compound

open access: yesIUCrJ, 2019
The present article is devoted to the characterization of the structural phase transitions of the [CH3NH3][Co(COOH)3] (1) perovskite-like metal–organic compound through variable-temperature single-crystal neutron diffraction.

Phenomenology of diffractive DIS in the framework of fracture functions and determination of diffractive parton distribution functions [PDF]

open access: yesPhys. Rev. D 99, 054007 (2019), 2019
The goal of this study is to determine a set of diffractive parton distribution function (diffractive PDFs) from a QCD analysis of all available and up-to-date diffractive deep inelastic scattering (diffractive DIS) data sets from HERA $ep$ collider, including the most recent H1 and ZUES combined inclusive diffractive cross section measurements.

Characterisation and Study of Compounds by Single Crystal X-ray Diffraction

open access: yesCrystals, 2020
A few years after the discovery in 1895 of X-rays by Röntgen, the first successful experiment single crystal X-ray diffraction (SCXRD) was reported by Laue, Friedrich, and Knipping [...]

Crystal Structure of 17α-Dihydroequilin, C18H22O2, from Synchrotron Powder Diffraction Data and Density Functional Theory

open access: yesCrystals, 2017
The crystal structure of 17α-dihydroequilin has been solved and refined using synchrotron X-ray powder diffraction data, and optimized using density functional techniques. 17α-dihydroequilin crystallizes in space group P212121 (#19) with a = 6.76849(1) Å,
