Tellurium and tellurium compounds

Lithium–tellurium batteries based on tellurium/ porous carbon composite

For the first time, lithiation/delithiation behavior of tellurium at room temperature was investigated using tellurium/porous carbon (Te/C) composite electrodes. The Te/C composite is synthesized by the infusion of liquid tellurium into a porous carbon host at the high temperature of 600 C under vacuum. Owing to the physical confinement of Te by porous carbon matrix, the Te/C electrode is capab...

Transformations of halogenated organic compounds under denitrification conditions.

Trihalomethanes, carbon tetrachloride, 1,1,1-trichloroethane, 1,2-dibromoethane, chlorinated benzenes, ethylbenzene, and naphthalene at concentrations commonly found in surface and groundwater were incubated under anoxic conditions to study their transformability in the presence of denitrifying bacteria. None of the aromatic compounds showed significant utilization relative to sterile controls ...

A glimpse on biological activities of tellurium compounds.

Tellurium is a rare element which has been regarded as a toxic, non-essential trace element and its biological role is not clearly established to date. Besides of that, the biological effects of elemental tellurium and some of its inorganic and organic derivatives have been studied, leading to a set of interesting and promising applications. As an example, it can be highlighted the uses of alka...

Tellurium in Organic Synthesis, IX [15] Oxidation of Some Nitrogenous Compounds with Te02

The reaction between bis(p-methoxyphenyl)telluroxide and various substituted phenylhydrazines has recently been reported [1]. In this reaction the phenylhydrazines are converted to the corresponding hydrocarbons and nitrogen, also producing bis(p-methoxyphenyl)telluride and an unsymmetrical telluride, resulting form aryl exchange. As a part of our investigation of the reactions of tellurium dio...
