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 ...
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 ...
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 ...
Bioactive hydroxyapatite/graphene composite coating and its corrosion stability in simulated body fluid
(Journal of Alloys and Compounds, 2015)
The hydroxyapatite/graphene (HAP/Gr) composite was electrodeposited on Ti using the electrophoretic deposition process to obtain uniform bioactive coating with improved mechanical strength and favorable corrosion stability ...
Combined XRD and XPS analysis of ex-situ and in-situ plasma hydrogenated magnetron sputtered Mg films
(Journal of Alloys and Compounds, 2015)
Contrary to traditional methods including top layer catalyst deposition and ex-situ hydrogenation in current study Mg-H films were synthesized using magnetron sputtering in Ar+ atmosphere and their in-situ hydrogenation ...
Anatase nanoparticles surface modified with fused ring salicylate-type ligands (1-hydroxy-2-naphthoic acids): A combined DFT and experimental study
(Journal of Alloys and Compounds, 2015)
Sensitization of TiO2 crystals and nanoparticles with appropriately chosen organic molecules can lead to a significant shift of their absorption threshold from the UV to the visible, thus improving the absorption of the ...
Raman spectroscopy of ZnS quantum dots
(Journal of Alloys and Compounds, 2015)
ZnS nanoparticles were synthesized mechanochemically by high-energy milling. In order to investigate influence off milling time to sample properties, samples were produced in three different milling times (5 min, 10 min ...
