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 ...
Electronic Processes in Solid State: Dirac Framework
(Sciendo, 2019)
The present paper proposes canonical Dirac framework adapted for application to the electronic processes in solid state. The concern is a spatially periodic structure of atoms distinguished by birth and annihilation of ...
Production of Phosphorescent Coatings on 6082 Aluminum Using Sr0.95Eu0.02Dy0.03Al2O4-δ Powder and Plasma Electrolytic Oxidation
(MDPI AG, 2019)
In this study, a new approach for producing phosphorescent aluminum coatings was studied. Using the plasma electrolytic oxidation (PEO) process, a porous oxide coating was produced on the Al6082 aluminum alloy substrate. ...
Traffic induced air pollution modeling: Scenario analysis for air quality management in street canyon
(Elsevier B.V., 2019)
Mathematical models are intensively used in environmental science for various reasons - status quo assessment, statistical modeling, forecasting, and planning, scenario analysis. Traffic flow and related atmospheric pollution ...
PVA Hydrogel Electrolyte and Porous Polyisoprene Carbon Nanostructure Composite Based Pressure Sensitive Supercapacitor
(Institute of Physics Publishing, 2019)
Narrow operational voltage window can be considered as one of the greatest limitations for aqueous polymer electrolytes. Using freeze-thaw hydrogel preparation method we have synthesized wider potential window electrolytic ...
Optical properties of zinc-iridium oxide thin films
(Institute of Physics Publishing, 2019)
We present the results of an investigation of ultraviolet, visible, near-infrared (UV-Vis-NIR) and X-ray absorption spectroscopy absorption spectra for zinc-iridium oxide (Zn-Ir- O) thin films with various iridium ...
Synthesis and studying of reduced few-layered graphene coatings in gas sensor applications
(Institute of Physics Publishing, 2019)
In this work reduced few-layered graphene (rFLG) nanoparticles were synthesized using electrochemical pulse exfoliation method from waste graphite crucibles. The regular change in voltage polarity in the synthesis process ...
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 ...
Effect of donor substituents on thermally activated delayed fluorescence of diphenylsulfone derivatives
(Elsevier B.V., 2019)
Diphenylsulfones substituted by acridan, carbazole, phenothiazine and phenoxazine moieties were synthesized and characterized by thermal analysis, UV-, steady-state and time-resolved luminescent spectrometries, cyclic ...
