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 ...
Recent progress in high-pressure X-ray absorption spectroscopy studies at the ODE beamline
(Taylor and Francis Ltd., 2020)
High pressure energy-dispersive X-ray absorption spectroscopy is a valuable structural technique, especially, when combined with a nano-polycrystalline diamond anvil cell. Here we present recent results obtained using the ...
Negative thermal expansion of ScF3: First principles vs empirical molecular dynamics
(Institute of Physics Publishing, 2019)
The crystal lattice of cubic scandium fluorine (ScF3) exhibits negative thermal expansion (NTE) over a wide range of temperatures from 10 K to 1100 K. Here the NTE effect in ScF3 is studied using atomistic simulations based ...
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 ...
Synthesis and characterization of ZnO/ZnS/MoS2 core-shell nanowires
(Elsevier B.V., 2017)
Hybrid nanostructures composed of layered materials have recently attracted a lot of attention due to their promising electronic and catalytic properties. In this study, we describe a novel synthesis strategy of ZnO/ZnS/MoS2 ...
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 ...
Origin of pressure-induced insulator-to-metal transition in the van der Waals compound FePS3 from first-principles calculations
(John Wiley and Sons Inc., 2020)
Pressure-induced insulator-to-metal transition (IMT) has been studied in the van der Waals compound iron thiophosphate (FePS3) using first-principles calculations within the periodic linear combination of atomic orbitals ...
Synthesis and vibration spectroscopy of nano-sized manganese oxides
(Polish Academy of Sciences, 2018)
X-ray diffraction, micro-Raman and the Fourier transform infrared spectroscopies as well as magnetometry measurements were performed on nanosized manganese oxides to probe their phase composition and magnetic properties. ...
Understanding of conversion process of magnetron deposited thin films of amorphous ReOx to crystalline ReO3 upon thermal annealing
(ACS Publications, 2020)
Thin films of rhenium trioxide (ReO3) were produced by reactive DC magnetron sputtering from metallic rhenium target followed by annealing in the air in the range of temperatures from 200C to 350C. Nanocrystalline ...
