Sensing oxides

In a general sense, oxidation refers to the introduction of oxygen or other electronegative atoms to organic molecules. In this context, a-hydroxylation of a... 

In a general sense, oxidation is a reaction in which a substance (molecule, atom or ion) loses electrons. These are transferred to another substance called - oxidant. The oxidation number of the substance being oxidized increases. Oxidation and reduction always occur simultaneously. In nature, oxidation reactions play an important role, e.g., in - respiration, metabolic processes, photooxidation, - corrosion and combustion, and, most importantly in electrochemistry, oxidation processes proceed at - anodes. 

The unsubstituted TTE 16 is nonaromatic, in the Hiickel sense. Oxidation to the cation radical and dication occurs sequentially and reversibly at relatively low potentials ( 1/2 = 0.37 V and 1/2 = 0.67 V vs. SCE in 147t-electron system. In contrast to the neutral TTF, both the cation radical and dication are aromatic as a result of the brt-electron heteroaromaticity of the 1,3-dithiolium cation. The radical cation and dication can be isolated as stable crystalline compounds due to the effective resonance stabilization of the aromatic dithiolium and, to a minor extent, the polarizable sulfur atoms <1996SR1, 1997SL1211, 1999PS99, 2001AGE1372>. 

Tin oxide is an -1ype semiconductor with ca. 3.8 eV energy gap. It is the basic material commonly used in gas sensing, oxidative catalysis, photocatalysis, dye-sensitized solar cell and conductive glass. In order to enhance the performance of SnOa-based device, many studies have been focused on the synthesis of nanostructure Sn02-based materials with controllable microstructure, particle size and physico-chemical properties [1-6]. The sol-gel method was reported to be a simple and reproducible route for one-step synthesis of nanostructured... 

Oxidation In a literal sense, oxidation is a reaction in which a substance combines with oxygen provided by an oxidizer or oxidizing agent.

At somewhat higher temperatures (40° to 100°c) than is usual for peroxidic oxidations, f-butyl hydroperoxide reacts with amines in an entirely different way from other hydroperoxides. The overall result is not substitution on nitrogen (although this may be the initial step), but the formation of various products arising from either hydrogen abstraction or dealkylation. In this sense, oxidation by f-butyl hydroperoxide at high temperatures is reminiscent ofnon-peroxidic reagents.
