Chromium in lead metasilicate glass: Solubility, valence, and local environment via multiple spectroscopy Abstract: In this article the doping of chromium in a lead metasilicate glass is explored using Raman, UV–Vis, and Cr K-edge XANES […]
Temperature dependence on phase evolution in the BaTiO3 polytypes studied using ab initio calculations Abstract: Identifying the forces that drive a temperature-induced phase transition is always challenging in the prospect of the first-principles methods. Herein, […]
Structural evolution, growth mechanism and photoluminescence properties of CuWO4 nanocrystals Abstract: Copper tungstate (CuWO4) crystals were synthesized by the sonochemistry (SC) method, and then, heat treated in a conventional furnace at different temperatures for 1 h. […]
Pristine carbon nitride as active material for high-performance metal-free supercapacitors: simple, easy and cheap Abstract: Understanding the basic properties of pristine carbon nitride electrodes is of great importance for their further applications as supercapacitor materials. To […]
Schottky contacts in germanium nanowire network devices synthesized from nickel seeds Abstract: This paper presents reliable process to the synthesis of germanium nanowires by the vapor-liquid-solid method using nickel as an alternative catalyst to gold, […]
Novel insights on the physicochemical properties of eumelanins and their DMSO derivatives Abstract: The biopigment eumelanin, ubiquitous in flora and fauna, is made up of chemically heterogeneous macromolecules based on the 5,6-dihydroxyindole and 5,6-dihydroxyindole-2-carboxylic acid […]
First-principles calculations and Raman scattering evidence for local symmetry lowering in rhombohedral ilmenite: temperature- and pressure-dependent studies Abstract: ATiO(3)-type materials may exist in two different crystalline forms: the perovskite and ilmenite. While many papers have devoted […]
Structural and photoluminescence properties of Eu3+ doped alpha-Ag2WO4 synthesized by the green coprecipitation methodology Abstract: Europium doped silver tungstates alpha-Ag2-3xEuxWO4 (x = 0, 0.0025, 0.005, 0.0075 and 0.01 mol) were synthesized by the coprecipitation method at […]
Rietveld refinement, cluster modelling, growth mechanism and photoluminescence properties of CaWO4:Eu3+ microcrystals Abstract: CaWO4:Eu3+ microcrystals (with 0, 1, 2 and 4 mol% Eu3+) were synthesized by a co-precipitation (CP) method and grown in a microwave-assisted hydrothermal […]
