Fast-Response Single-Nanowire Photodetector Based on ZnO/WS2 Core/Shell Heterostructures
(American Chemical Society, 2018)
The surface plays an exceptionally important role in nanoscale materials, exerting a strong influence on their properties. Consequently, even a very thin coating can greatly improve the optoelectronic properties of ...
Formation of dislocations in LiF irradiated with 3He and 4He ions
(Elsevier B.V., 2018)
Influence of the irradiation with 13.5 MeV 3He and 5 MeV 4He ions on the micro-structure and mechanical properties of LiF single crystals was studied. The depth profiles of nanoindentation, dislocation mobility, selective ...
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 ...
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) ...
Probing the Thermochromic Phase Transition in CuMoO4 by EXAFS Spectroscopy
(Wiley-VCH Verlag, 2018)
Extended X-ray absorption fine structure (EXAFS) spectroscopy at the Mo K-edge is used to follow the thermochromic γ-to-α phase transition in copper molybdate (CuMoO4). The temperature dependence (10–300 K) of the radial ...
X-ray absorption near edge spectroscopy of thermochromic phase transition in CuMoO4
(Institute for Low Temperature Physics and Engineering, 2018)
Thermochromic phase transition was studied in CuMoO4 using the Cu and Mo K-edge x-ray absorption spec-troscopy in the temperature range of 10-300 K. The hysteretic behavior has been evidenced from the tempera-ture dependence ...
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 ...
