This is well known that the selectivity and sensitivity of tin dioxide (SnO2) thin film sensors for the detection of low concentration of volatile sulfides such as H2S in air can be improved by small amount of Ag additives. In this paper we present the results of comparative X-ray photoelectron spectroscopy (XPS), thermal desorption spectroscopy (TDS), and atomic force microscopy (AFM) studies ...

nous proposons d'examiner comparativement la chantefable franqaise Aucassin et Nicolette dans laquelle nous voyons une v~ritable composition dramatique oil <~ les indications qui accompagnent les r~pliques et les indications du mouvement qui les suivent sont analogues aux indications sc6niques de nos pi~ces de th&~tre)~ et le drame romanesque du porte Mihai Eminescu Mira, d'une longueur de text...

using titanium dioxide nano-silver packaging, which is antibacterial and resistance to the diffusion of gases such as oxygen, is increasing in food industry. therefore, we compared the effect of titanium dioxide-based nano-silver packaging and conventional polyethylene packaging on the fungal flora of consuming bread in order to increase the shelf-life storage of consuming bread. one hundred fo...

In this work, we present the electrochemical deposition of manganese dioxide (MnO₂) thin films on carbon-coated TiN/Si micro-pillars. The carbon buffer layer, grown by plasma enhanced chemical vapor deposition (PECVD), is used as a protective coating for the underlying TiN current collector from oxidation, during the film deposition, while improving the electrical conductivity of the stack. A c...

Nanocrystalline SnOx particles (x 0–2) were synthesized using tetramethyltin (Sn(CH3)4) vapor as the particle precursor reactant in hydrogen/oxygen/argon (H2/O2/Ar) flames. The particle composition and morphology were characterized using X-ray diffractometry, transmission electron microscopy, and nitrogen (N2) surface adsorption. By controlling the concentration of oxygen in the reactant gases ...

In this research, investigated characterization of pure and Cobalt doped Tin dioxide SnO2: Co with 3, 5 7wt% fabricated using radio frequency magnetron sputtering method deposited on glass surfaces. The results showed that prepared were nano films poly crystalline in form favored reflection permanently (110) plan, the crystallite size decreases as concentration increased 9-14 nm. opt...
