A comparative study of heterostructured CuO/CuWO4 nanowires and thin films
(Elsevier B.V., 2017)
A comparative study of heterostructured CuO/CuWO4 core/shell nanowires and double-layer thin films was performed through X-ray diffraction, confocal micro-Raman spectroscopy and electron (SEM and TEM) microscopies. The ...
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 ...
Depth profiles of damage creation and hardening in MgO irradiated with GeV heavy ions
(Elsevier B.V., 2019)
The effect of irradiation with GeV heavy ions (U, Au, Bi) on the structure and mechanical properties of MgO single crystals was studied. The methods of nanoindentation, dislocation mobility, optical absorption and ...
Influence of Nb-doping on the local structure and thermoelectric properties of transparent TiO2:Nb thin films
(Elsevier Ltd, 2020)
Transparent n-type niobium-doped titanium dioxide thin films (TiO2:1.5 at.%Nb) with pronounced thermoelectric properties were produced from a composite Ti:Nb target by reactive magnetron sputtering. The thin films were ...
High-temperature X-ray absorption spectroscopy study of thermochromic copper molybdate
(Acta Materialia Inc, 2019)
X-ray absorption spectroscopy at the Cu and Mo K-edges was used to study the effect of heating on the local atomic structure and dynamics in copper molybdate (α-CuMoO4) in the temperature range from 296 to 973 K. The reverse ...
Magnon and Phonon Excitations in Nanosized NiO
(Sciendo, 2019)
Single-crystal, microcrystalline and nanocrystalline nickel oxides (NiO) have been studied by Raman spectroscopy. A new band at ~200 cm-1 and TO-LO splitting of the band at 350–650 cm-1 have been found in the spectra ...
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) ...
Pressure-induced structural changes in α-MoO3 probed by X-ray absorption spectroscopy
(Institute of Physics Publishing, 2019)
Energy-dispersive X-ray absorption spectroscopy at the Mo K-edge was used to study pressure-induced (up to 36 GPa) changes in the local atomic structure of 2D layered oxide α-MoO3. A linear combination analysis based on ...
Treatment of disorder effects in X-ray absorption spectra beyond the conventional approach
(Elsevier Ltd., 2020)
The contribution of static and thermal disorder is one of the largest challenges for the accurate determination of the atomic structure from the extended X-ray absorption fine structure (EXAFS). Although there are a number ...
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 ...
