Low temperature afterglow from SrAl 2 O 4 : Eu, Dy, B containing glass
(Acta Materialia Inc, 2021)
SrAl2O4: Eu, Dy, B particles were added in a phosphate glass (90NaPO3-10NaF (in mol%)) using the direct doping method. For the first time, the composition of the particles prior to and after embedding them in the glass was ...
Synthesis and characterization of GaN/ReS2, ZnS/ReS2 and ZnO/ReS2 core/shell nanowire heterostructures
(Elsevier B.V., 2021)
Layered 2D van der Waals (vdW) materials such as graphene and transition metal dichalcogenides have recently gained a great deal of scientific attention due to their unique properties and prospective applications in various ...
Thermal annealing and transformation of dimer F centers in neutron-irradiated Al2O3 single crystals
(Elsevier B.V., 2021)
The precise study of the thermal annealing of the F2-type dimer defects, being under discussion in the literature for a long time and responsible for the number of absorption bands below 4.5 eV, has been performed in ...
Changes in freshwater sediment microbial populations during fermentation of crude glycerol
(Pontificia Universidad Catolica de Valparaiso, 2021)
Background: This work studied how the exposure to an unusual substrate forced a change in microbial populations during anaerobic fermentation of crude glycerol, a by-product of biodiesel production, with freshwater sediment ...
Thickness-dependent properties of ultrathin bismuth and antimony chalcogenide films formed by physical vapor deposition and their application in thermoelectric generators
(Elsevier B.V., 2021)
In this work, a simple cost-effective physical vapor deposition method for obtaining high-quality Bi2Se3 and Sb2Te3 ultrathin films with thicknesses down to 5 nm on mica, fused quartz, and monolayer graphene substrates is ...
Study of the thermochromic phase transition in CuMo1−xWxO4 solid solutions at the W L3-edge by resonant X-ray emission spectroscopy
(Elsevier Ltd., 2021)
Polycrystalline CuMo1−xWxO4 solid solutions were studied by resonant X-ray emission spectroscopy (RXES) at the W L3-edge to follow a variation of the tungsten local atomic and electronic structures across thermochromic ...
Synthesis and luminescent properties of Mn-doped alpha-tricalcium phosphate
(Elsevier, 2021)
In this work, a series of Mn2+-doped α-tricalcium phosphate (α-TCP) powders was synthesized by wet co-precipitation method followed by high-temperature annealing and thermal quenching. It was shown that Mn2+-doped α-TCP ...
