Selenese provides commands for performing actions in a browser (click a link, select an option) and for retrieving data from the resulting pages. Selenese serves as the language for composing Selenium Commands, which are utilized in the testing of web applications.
Another class of reactions is the complexation of selenourea with transition metals and metalloids. Its ability to act as an effective ligand is attributed to the electron-donating effect of the amino groups and consequent stabilization of the selenium–metal π bond. In selenourea complexes only selenium–metal bonding has been observed ...
Selenium is found in metal sulfide ores, where it substitutes for sulfur. Commercially, selenium is produced as a byproduct in the refining of these ores. Minerals that are pure selenide or selenate compounds are rare. The chief commercial uses for selenium today are glassmaking and pigments. Selenium is a semiconductor and is used in photocells.
Selenium is a component of the amino acids selenocysteine and selenomethionine. In humans, selenium is a trace element nutrient that functions as cofactor for glutathione peroxidases and certain forms of thioredoxin reductase. [1] Selenium-containing proteins are produced from inorganic selenium via the intermediacy of selenophosphate (PSeO 3 3 ...
The Riley oxidation is a selenium dioxide-mediated oxidation of methylene groups adjacent to carbonyls.It was first reported by Harry Lister Riley and co-workers in 1932. [1] ...

Iodine supplementation in selenium-deficient populations is theoretically problematic, partly for this reason. [8] Selenocysteine (abbreviated as Sec or U, in older publications also as Se-Cys) [80] is the 21st proteinogenic amino acid, and is the root of iodide ion toxicity when there is a simultaneous insufficiency of biologically available ...
