Nano-sized titanium dioxide TiO2 powder was prepared by new wet chemical route from its precursor Titanium (IV) chloride (TiCl4) as precursor with isopropoxy alcohol in presence of nitric acid under ambient condition. Their morphologies, phase compositions and components of the TiO2 nanoparticles were characterized by transmission electron ...

The solvent extraction of gallium from a concentrated Jajarm Bayer process liquor containing 164.90 g/l of Na2O, 86.70 g/l of Al2O3 and 106.02 ppm of gallium was investigated using 10 vol.% Kelex100, a 7-alkyl substituted-8 hydroxyquinoline as an extractant, 10 vol.% etanol as a modifier and kerosene as a diluent. At (Vo :Va = 1.0:1.0) ...

However, in situ X-ray diffraction (XRD) studies on the lithiation /delithiation of Si anodes confi rmed the absence of the above-mentioned stable compounds in the electrochemical reaction in Li-ion batteries at room temperature. [ 12,13 ] The only crystalline lithium silicide formed is Li 15 Si 4 (space group 43 I d), a metastable phase that decomposes to Li 13 Si 4 , Li 17 Si 4 /Li 4.11 Si, o...

The limit to which the phase change memory material Ge2Sb2Te5 can be scaled toward the smallest possible memory cell is investigated using structural and optical methodologies. The encapsulation material surrounding the Ge2Sb2Te5 has an increasingly dominant effect on the material’s ability to change phase, and a profound increase in the crystallization temperature is observed when the Ge2Sb2Te...

Orthonormal bases of compactly supported wavelet bases correspond to subband coding schemes with exact reconstruction in which the analysis and synthesis filters coincide. We show here that under fairly general conditions, exact reconstruction schemes with synthesis filters different from the analysis filters give rise: to two dual Riesz bases of compactly supported wavelets. We give necessary ...

in regard to both implementation of the second phase of targeted subsidises and the effect of inflation resulted from first phase of it on economic of country, inflation content estimation on economic of country especially agriculture sector is necessary. in this research effect of increasing price of energy carriers on inflation in various reproduction sectors such as agriculture was investiga...

In Part I of this diptych, we outlined the theory and an analysis methodology for quantitative phase recovery from real-space distortions Fresnel images acquired in parallel mode transmission electron microscopy (TEM). that work, properties method, termed TEM-differential contrast (TEM-DPC), were highlighted through use simulated data. explore TEM-DPC technique with experimental cryo-TEM a thin...

Zirconia ZrO 2 is one of the most important modern materials, but its use faces problem complex polymorphism. It generally accepted that, under normal conditions, it exists in monoclinic form P2_1/c (N 14), which undergoes an extended martensitic transformation into tetragonal P4_2/nmc 137) when heated above 1000 o C. However, group-theoretic analysis forbids a direct transition between these s...

The performance of football players within game context can be analyzed based on their ability to break or (re)balance the attacker-defender dyad. In this context, the analysis of each sub-phase (e.g., 1v1, 2v2) presents a feature that needs to be taken into account in sports analysis. This study aims to investigate the interpersonal dynamics dyad formed by the attacker and the defender in 1v1 ...
