Plasma-wall interaction studies within the EUROfusion consortium: Progress on plasma-facing components development and qualification
(Institute of Physics Publishing, 2018)
The provision of a particle and power exhaust solution which is compatible with first-wall components and edge-plasma conditions is a key area of present-day fusion research and mandatory for a successful operation of ITER ...
Photovoltaic effect in bulk heterojunction system with glass forming indandione derivative DMABI-6Ph
(Elsevier Ltd, 2018)
The aim of the work is to evaluate possible use of 2-[[4-(bis(2-trityloxyethyl)amino)phenyl]methylene]indane-1,3-dione (DMABI-6Ph) as light absorbing material for solar cells. DMABI-6Ph is a perspective material due to its ...
Surface termination effects on the oxygen reduction reaction rate at fuel cell cathodes
(Royal Society of Chemistry, 2018)
The results of first principles calculations of oxygen vacancy and oxygen adsorbate concentrations are analyzed and compared for the polar (La,Sr)O and MnO2 (001) terminations of (La,Sr)MnO3 fuel cell cathode materials. ...
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 ...
Surface relief grating recording in azobenzene epoxy films
(National Institute of Optoelectronics, 2018)
In this work the direct one step formation of surface relief gratings (SRG) in azo-epoxy polymer films during holographic recording was studied. In this material azo-compound is covalently attached to epoxy forming polymer. ...
Optical detection of paramagnetic centres in activated oxyfluoride glass-ceramics
(Polish Academy of Sciences, 2018)
Electron paramagnetic resonance (EPR), magnetic circular dichroism (MCD) and EPR detected via MCD (MCD-EPR) investigations have been performed on rare-earth activated oxyfluoride glasses and glass-ceramics. Er3+, Gd3+, and ...
Systematic trends in (0 0 1) surface ab initio calculations of ABO3 perovskites
(Elsevier B.V., 2018)
By means of the hybrid exchange–correlation functionals, as it is implemented in the CRYSTAL computer code, ab initio calculations for main ABO3 perovskite (0 0 1) surfaces, namely SrTiO3, BaTiO3, PbTiO3, CaTiO3, SrZrO3, ...
