On the Electronic Structures of the M-Centers in Alkali-halide Crystals [PDF]

open access: yesProgress of Theoretical Physics, 1952
The electronic energy levels of the M-centers in the colored LiCI and NaCl crystals are calculated by LCAO method, assuming Seitz's model. The ground state and the first excited state (optically permitted) are shown to belong to A, and B, symmetry, respectively, the wave-lengths of the optical transition between them being in comparatively good ...

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Mechanisms of influence of modifiers on crystallization of tin and aluminium bronzes

open access: yesЛитьë и металлургия, 2023
It has been shown that elementary crystalline cells of α‑phases of tin, aluminum bronzes and main modifying phases do not correspond to the principle of structural and dimensional correspondence of Dankov‑Konobeevsky.

A visualization of the damage in Lead Tungstate calorimeter crystals after exposure to high-energy hadrons

open access: yes, 2012
The anticipated performance of calorimeter crystals in the environment expected after the planned High-Luminosity upgrade of the Large Hadron Collider (HL-LHC) at CERN has to be well understood, before informed decisions can be made on the need for ...

Features of isothermal crystallization of ammonium sulphate

open access: yesProceedings of the NTUU "Igor Sikorsky KPI". Series: Chemical engineering, ecology and resource saving, 2021
Soil fertility is rapidly decreasing due to irrational land use, erosion and soil pollution and adverse weather conditions. The use of composite granular organic-mineral fertilizers that contain mineral and organic components allows the soil fertility to

NANOSTRUCTURAL PROCESSES AT MELTING AND MOULDING OF SILUMINS

open access: yesВесці Нацыянальнай акадэміі навук Беларусі: Серыя фізіка-тэхнічных навук, 2017
The existing theories of liquid state, crystallization and modifying don’t allow determining nanostructural physical and chemical mechanisms of melting and casting of silumins.
