Y2O3:Yb,Tm and Y2O3:Yb,Ho powders for low-temperature thermometry based on up-conversion fluorescence
(Elsevier, 2013)
Recently, trivalent rare earth doped materials have received significant attention due to the strong temperature dependence of the fluorescence emission of these materials, which can be useful in temperature sensing. Here, ...
Preparation and properties of porous, biomorphic, ceria ceramics for immobilization of Sr isotopes
(Elsevier, 2013)
A new technology for radionuclide trapping which is based on bio-templating approach was proposed in this paper. Porous oxide ceramics was prepared by wet impregnation of biological template with water solution of cerium ...
Properties of 3Y-TZP zirconia ceramics with graphene addition obtained by spark plasma sintering
(Elsevier, 2018)
In this study the influence of graphene addition on the microstructure, phase composition, mechanical, and electrical properties of 3Y-TZP ceramics was investigated. Blends of pure 3Y-TZP and with addition of 1 − 4 vol% ...
Microstructure and dielectric properties of Dy/Mn doped BaTiO3 ceramics
(Elsevier, 2014)
Dy/Mn doped BaTiO3 with different Dy2O3 contents, ranging from 0.1 to 5.0 at% Dy, were investigated regarding their microstructural and dielectric characteristics. The content of 0.05 at% Mn was constant in all the ...
Electrochemical and structural study on cycling performance of γ-LiV2O5 cathode
(Elsevier BV, 2021)
Electrochemical and structural properties of LiV2O5 cathode were investigated. Obtained by solid state reaction at high temperature the material crystallized as gamma polymorph phase, γ-LiV2O5. The gamma structure provides ...
Monitoring of transformations in bentonite after NaOH-TMA treatment
(Oxford : Elsevier Sci, 2007)
Semi-quantitative methods of X-ray diffraction and FTIR-spectroscopy, accompanied by electron microscopy, X-ray microanalysis and others were used to monitor structural-phase reorganizations occurring in a smectite-gypsum ...
Dry-pressed anodized titania nanotube/CH3NH3PbI3 single crystal heterojunctions: The beneficial role of N doping
(Elsevier, 2019)
Highly ordered, anodically grown TiO 2 nanotubes on titanium supports were annealed in ammonia atmosphere in order to incorporate nitrogen doping (≤2 at.%) in the titanium oxide lattice. FESEM micrographs revealed nanotubes ...
Structural and electrical properties of sintered zinc-titanate ceramics
(Elsevier, 2009)
The aim of this work was an investigation of structural and electrical properties of sintered zinc-titanate ceramics obtained by mechanical activation. Mixtures of ZnO and TiO2 were mechanically activated in a planetary ...
Influence of ageing of milled clay and its composite with TiO2on the heavy metal adsorption characteristics
(Elsevier, 2015)
The aim of the present study was to investigate the effect of ageing of mechanochemically synthesized clay and its TiO2composite on the simultaneous removal of Pb(II), Cd(II), Cu(II) and Zn(II) ions from acidic aqueous ...
Structural Investigation of Mechanically Activated Nanocrystalline BaTiO3 Powders
(Elsevier, 2011)
In this article, in order to obtain tetragonal nanocrystalline BaTiO3, structural investigations of mechanically activated BaTiO3 powder have been performed. A mercury porosimetry analysis and scanning electron microscopy ...
