Advanced approach to the local structure reconstruction and theory validation on the example of the W L3-edge extended X-ray absorption fine structure of tungsten
(IOP Publishing, 2018)
Atomistic simulations of the experimental W L3-edge extended x-ray absorption fine structure (EXAFS) of bcc tungsten at T = 300 K were performed using classical molecular dynamics (MD) and reverse Monte Carlo (RMC) methods. ...
Influence of Pressure and Temperature on X-Ray Induced Photoreduction of Nanocrystalline CuO
(Sciendo, 2018)
X-ray absorption spectroscopy at the Cu K-edge is used to study X-ray induced photoreduction of copper oxide to metallic copper. Although no photoreduction has been observed in microcrystalline copper oxide, we have found ...
Kinetic Monte Carlo modeling of Y2O3 nano-cluster formation in radiation resistant matrices
(Elsevier B.V., 2018)
As known, Y2O3 nano-clusters considerably increase radiation resistance of reactor construction materials. To model the nano-cluster formation kinetics, we propose the simplest possible mathematical model and perform kinetic ...
Investigation of precipitate in an austenitic ODS steel containing a carbon-rich process control agent
(Elsevier Ltd, 2018)
Austenitic oxide dispersion strengthened (ODS) steels are one of the candidates as a structural material for high-temperature applications in future power plants. To guarantee the necessary high production yield, the ...
Local structure of A-atom in ABO3 perovskites studies by RMC-EXAFS
(Elsevier Ltd, 2018)
The ferroelectric distortions in perovskites were a subject of numerous investigations for a long time. However, some controversial results still exist, coming from the analysis of diffraction (X-ray, neutron or electron) ...
Neural Network Approach for Characterizing Structural Transformations by X-Ray Absorption Fine Structure Spectroscopy
(American Physical Society, 2018)
The knowledge of the coordination environment around various atomic species in many functional materials provides a key for explaining their properties and working mechanisms. Many structural motifs and their transformations ...
ODS ferritic steels obtained from gas atomized powders through the STARS processing route: Reactive synthesis as an alternative to mechanical alloying
(Elsevier Ltd, 2018)
Oxide Dispersion Strengthened Ferritic Stainless Steels (ODS FS) are candidate materials for structural components in fusion reactors. Their ultrafine microstructure and the presence of a very stable dispersion of Y-Ti-O ...
Origin of Pressure-Induced Metallization in Cu3N: An X-ray Absorption Spectroscopy Study
(Wiley-VCH Verlag, 2018)
High-pressure (0–26.7 GPa) Cu K-edge X-ray absorption spectroscopy is used to study possible structural modifications of anti-perovskite-type copper nitride (Cu3N) crystal lattice. The analysis of X-ray absorption near-edge ...
