In this work, we study the effects of treating nanostructured SnO2–SiO2 films derived by a sol-gel method with nitrogen and oxygen plasma. The structural chemical properties are closely investigated. To quantify surface site activity in following treatment, employed photocatalytic UV degradation test brilliant green. Using X-ray photoelectron spectroscopy, it was found that treatment plasma led...

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.

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.

Substantial improvement is needed in efficient and affordable decolorization disinfection methods to solve the issues caused by dyes harmful bacteria water wastewater. This work involves photocatalytic degradation of methylene blue (MB) as well gram-negative gram-positive cobalt-doped tin oxide (Co-SnO2) nanoparticles (NPs) Co-SnO2/SGCN (sulfur-doped graphitic carbon nitride) nanocomposites (NC...

Sulfur dioxide (SO2) is a typical sulfur hexafluoride (SF6) decomposition by product in gas insulated switchgear (GIS). Online monitoring and analyzing SO2 gas concentration can timely and effectively evaluate the insulation performance of SF6-gas-insulated apparatus. In this study, pure and 3 at % Cu-doped SnO2 microspheres were synthesized via a simple and facile hydrothermal method, and were...

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...

In this work, semiconductor tin oxide (II) (SnO) nanoparticles and plates were synthesized at room conditions via a hydrolysis procedure. X-ray diffraction (XRD) transmission electron microscopy (TEM) confirmed the high crystallinity of as-synthesized romarchite SnO with dimensions ranging from 5 to 16 nm. The stability initial controlled oxidation SnO2 was studied based on either thermal treat...

The integration of gas sensor components into smart phones, tablets and wrist watches will revolutionize the environmental health and safety industry by providing individuals the ability to detect harmful chemicals and pollutants in the environment using always-on hand-held or wearable devices. Metal oxide gas sensors rely on changes in their electrical conductance due to the interaction of the...
