Electrical and magnetotransport properties of polycrystalline tin dioxide films were investigated in the temperature range 2-300 K and in high magnetic fields up to 27 T. The experimental data were analyzed using models inherent both for 2D and 3D disordered systems. A crossover from 2D to 3D behaviour was observed as the temperature was increased.
Two 10 and 20nm samples of Cu nano-cluster were grown on quartz substrates with a thickness of by electron beam deposition method. Nanolayers of titanium dioxide with a thickness of 300 nm were deposited on these Cu nano-cluster layers. For comparison، a layer of titanium dioxide with a thickness of 300 nm was also coated on quartz substrate. All coatings were conducted using electron-beam phys...
In the synthesis of five-membered heterocycles by the annulation of epoxides with heterocumulenes such as carbon dioxide and isocyanates, we developed the indium-tin catalytic system and synthesized various cyclic adducts including novel types products under mild reaction conditions.
Hierarchical anatase TiO(2) nano-architecture arrays consisting of long TiO(2) nanowire trunk and numerous short TiO(2) nanorod branches on transparent conductive fluorine-doped tin oxide glass are successfully synthesized for the first time through a facile one-step hydrothermal route without any surfactant and template. Dye-sensitized solar cells based on the hierarchical anatase TiO(2) nano-...
The metal catalyst has good electrical conductivity, is simple to prepare and easy be applied in practice. It currently the most in-depth researched for electrochemical reduction of carbon dioxide. In recent decades, metals such as copper, cobalt, tin, gold have been used electrode catalysts reducing From perspective mechanism dioxide, it generally believed that formation C intermediate rate-de...
Lattice constant, cohesive energy, direct band gap and valence band width had been calculated for grey tin by using ( CNDO-LUC ) method, then we had been making a comparison with experimental and other workers results for ( C, Si, Ge and Sn ) with zinc-blende structure in order to study the efficiency of this method. The results had showed that this method is good for lattice constant and bad f...
Metal oxide sensors were created using nanosized tin dioxide obtained by a sol-gel method. Gas-sensitive layers of the sensors were impregnated with PdCl2 solutions of different concentrations to increase sensitivities of the proposed sensors. Influence of different temperature conditions of the sensor formation on the sensor properties was studied. It was found that decreasing duration of high...
