Selenium, a critical micronutrient for human and animal health, exhibits a complex cycle in plant and soil systems, where its chemical speciation dictates both bioavailability and potential toxicity.

Researchers from the Wuhan National Laboratory for Optoelectronics (WNLO) in China have fabricated a selenium (Se) solar cell with a selenium-tellurium (Se-Te) absorber, which they claim can optimize ...

Absorption Absorption of selenium is efficient and is not regulated. More than 90 percent of selenomethionine, the major dietary form of the element, is absorbed by the same mechanism as methionine ...

THE fact that selenium dioxide, a white solid, gives a brown vapour has been discussed by Meyer and Langner (Ber., 60 B, 285; 1927), who conclude that the colour must be due to the dioxide and cannot ...
