Various macrokinetic models (Avrami, Evans, Tobin, Malkin, Dietz, Nakamura, and modified first-order models) were applied to describe non-isothermal crystallization kinetics of Eu3+ doped zinc silicate powders prepared via ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
