Copper-/Zinc-Doped TiO Nanopowders Synthesized by Microwave-Assisted Sol-Gel Method.

Using the microwave-assisted sol-gel method, Zn- and Cu-doped TiO nanoparticles with an anatase crystalline structure were prepared. Titanium (IV) butoxide was used as a TiO precursor, with parental alcohol as a solvent and ammonia water as a catalyst. Based on the TG/DTA results, the powders were thermally treated at 500 °C.

Nanoscale Control of Structure and Composition for Nanocrystalline Fe Thin Films Grown by Oblique Angle RF Sputtering.

The use of Fe films as multi-element targets in space radiation experiments with high-intensity ultrashort laser pulses requires a surface structure that can enhance the laser energy absorption on target, as well as a low concentration and uniform distribution of light element contaminants within the films. In this paper, (110) preferred orientation nanocrystalline Fe thin films with controlled morphology and composition were grown on (100)-oriented Si substrates by oblique angle RF magnetron sputtering, at room temperature. The evolution of films key-parameters, crucial for space-like radiation experiments with organic material, such as nanostructure, morphology, topography, and elemental composition with varying RF source power, deposition pressure, and target to substrate distance is thoroughly discussed.

Influence of Sintering Strategy on the Characteristics of Sol-Gel BaCeTiO Ceramics.

Single-phase Ce-doped BaTiO powders described by the nominal formula BaCeTiO with = 0.005 and 0.05 were synthesized by the acetate variant of the sol-gel method.

BiEuFeO Powders: Synthesis, Characterization, Magnetic and Photoluminescence Properties.

Europium substituted bismuth ferrite powders were synthesized by the sol-gel technique. The precursor xerogel was characterized by thermal analysis. BiEuFeO (x = 0-0.
