Surfactant-assisted synthesis of Barium hexaferrite nanoparticles by hydrothermal method

In the present work, the synthesis of Barium hexaferrite (BaFe12O19) nanoparticles in thepresence of a large excess amount of OH− anions by the hydrothermal method in the presence and absence of surfactants such as Sodium dodecyl benzene sulfonate and Triton X-114 was reported. The optimized temperature in the absence of surfactant was determined (200 °C) and then Barium hexaferrite nanoparticl...

Photoluminescence and hydrogen gas-sensing properties of titanium dioxide nanostructures synthesized by hydrothermal treatments.

Titanium dioxide (TiO(2)) nanostructures were synthesized by microwave-assisted and conventionally heated hydrothermal treatment of TiO(2) powder. The tubular structures were converted to a rodlike shape by sintering the samples at various temperatures in air for 3 h. This was accompanied by phase transformation largely influenced by the method of synthesis and the mode of heating. The X-ray di...

Fabrication of p-Type Nano-porous Silicon Prepared by Electrochemical Etching Technique in HF-Ethanol and HF-Ethanol-H2O Solutions

Nano-porous silicon were simply prepared from p-type single crystalline silicon wafer by electrochemical etching technique via exerting constant current density in two different HF-Ethanol and HF-Ethanol-H2O solutions. The mesoporous silicon layers were characterized by field emission scanning electron microscopy and scanning electron microscopy. The results demonstrate that the width of nano-p...

Gas Sensing Properties of SnO2 Thin Films Modified by Ag Nanoclusters Synthesized by SILD Method

The effect of SnO2 surface modification by Ag nanoclusters, synthesized by SILD method, on the operating characteristics of thin film gas sensors was studied and models for the promotional role of Ag additives were discussed. It was found that mentioned above approach can be used for improvement both the sensitivity and the rate of response of the SnO2-based gas sensors to CO and H2. At the sam...
