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.

ON DIFFRACTION BY A STRIP [PDF]

open access: yesProceedings of the National Academy of Sciences, 1954
The problem of diffraction by an infinite strip or slit has been the subject of several investigations. There are at least two "exact" methods for attacking this problem. One of these is the integral equation method, the other the Fourier-Lame method.

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 ...

Structural determination and packing analysis of a cholesteryl caprate/cholesteryl laurate solid solution.

open access: yesJournal of Lipid Research, 1994
This paper describes the X-ray crystal structure analysis of a cholesteryl ester solid solution, cholesteryl decanoate/cholesteryl laurate, grown from a bulk concentration with molar ratio 0.56/0.43. The unit cell is monoclinic with a = 12.969, b = 9.048,

Scattering from a Truncated Metamaterial Layer Hosted by a Planar PEC Structure: Uniform Asymptotic Solution and Validation Tests

open access: yesApplied Sciences, 2022
This research paper proposes an analytical approach for evaluating electromagnetic scattering from a planar complex object made of a perfect electric conductor, which hosts a double negative metamaterial half-layer on the lit face. The method is based on

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.
