XAFS and XPS analysis of Zn0.98Fe0.02Te0.91Se0.09 semiconductor
(Journal of Alloys and Compounds, 2015)
Local structures and electronic properties of II-VI quaternary Zn0.98Fe0.02Te0.91Se0.09 mixed crystal are studied by X-ray absorption fine structure (XAFS) while the surface composition and its oxidation in air are studied ...
Structural and magnetic properties of hydrothermally synthesized beta-MnO2 and alpha-KxMnO2 nanorods
(Elsevier, 2016)
Hydrothermal synthesis was applied for obtaining different manganese dioxide polymorphs whose morphology, structure and magnetic properties were thoroughly investigated. Variations in the synthesis pathways lead to the ...
Magnetic properties of NiO (nickel oxide) nanoparticles: Blocking temperature and Neel temperature
(Journal of Alloys and Compounds, 2015)
Crystalline nickel oxide (NiO) nanoparticles dispersed in an amorphous silica matrix have been prepared by a sol-gel combustion synthesis method. The sample was characterized using X-ray powder diffraction, energy-dispersive ...
Synthesis and microstructural properties of mixed iron-gallium oxides
(Journal of Alloys and Compounds, 2015)
Various mixed Fe-Ga oxides were prepared by the calcination of mixed Fe-Ga oxyhydroxide precursors (alpha-Fe1 xGaxOOH solid solutions, 0 LT = x LT = 1) at 500 or 1000 degrees C. Isostructural corundum-type oxides alpha-Fe2O3 ...
Site preference of Hf dopant in Ni3Al alloys: A perturbed angular correlation study
(Journal of Alloys and Compounds, 2015)
Perturbed angular correlation measurements of the hyperfine interactions of the Ta-181 probe in the polycrystalline intermetallic Ni3Al doped with 0.5 and 5 at.% Hf were performed in the temperature range 78-1230 K. The ...
Characterization and luminescent properties of Eu3+ doped Gd2Zr2O7 nanopowders
(Journal of Alloys and Compounds, 2015)
Nanopowders based on gadolinium zirconium oxide (Gd2Zr2O7) doped by europium ions (Eu3+) were successfully prepared using a flame combustion method. This material is suitable for various optical devices. The structure of ...
Preparation of ZrO2 and ZrO2/SiC powders by carbothermal reduction of ZrSiO4
(Journal of Alloys and Compounds, 2011)
This paper is dealing with the synthesis of zirconia/silicon carbide (ZrO2/SiC) and ZrO2 powders obtained by carbothermal reduction of natural mineral zircon (ZrSiO4). For the first time, the influence of carbon to ZrSiO4 ...
Surface structural heterogeneity of high power plasma-sprayed hydroxyapatite coatings
(Journal of Alloys and Compounds, 2016)
The aim of this work was to examine the dependence of the local surface structure (surface structural heterogeneity) on the local thickness (thickness uniformity) and structure properties along the thickness of hydroxyapatite ...
Sintering and electrical properties of Ce1-xBixO2-delta solid solution
(Journal of Alloys and Compounds, 2014)
Solid solution Ce1-xBixO2-delta nanopowders with the composition of x = 0.1-0.5 were synthesized by using Self Propagating Room Temperature procedure (SPRT). The results obtained by XRPD show that synthesized samples were ...
Structural investigation of mechanically activated ZnO powder
(Journal of Alloys and Compounds, 2015)
Commercially available ZnO powder was mechanically activated in a planetary ball mill. In order to investigate the specific surface area, pore volume and microstructure of non-activated and mechanically activated ZnO powders ...
