The approach to the problem of the Se-polysaccharides presented in the current review is based precisely on the analysis of the structure of these compounds and related changes in biological activity. To our knowledge, an extensive analysis of the chemical structures of seleno-carbohydrates (with a...
Industrial production of selenium usually involves the extraction of selenium dioxide from residues obtained during the purification of copper. Common production from the residue then begins by oxidation with sodium carbonate to produce selenium dioxide, which is mixed with water and acidified to form se...

The Se vacancies can be used as the strong Lewis acid site, which can effectively enhance the adsorption of N atoms, and cooperate with Ni substitution to optimize the adsorption behavior of amine. Despite the significant impact of Se vacancy engineering on the broad field of electrocatalysis, a...
dioxide fixation, as well as the oxidative fragmentation of the pentose substrate, but the L subunit of Rubisco was down-regulated when treated with high concentrations of selenium in the leaves. The carbon fixation in dark reaction was also inhibited by high concentrations of selenium through down...

Selenium (Se) is an essential micronutrient for humans, animals and some lower plants at very low concentrations, whereas it is extremely toxic at higher doses. Furthermore, living organisms become exposed to high Se concentrations via both anthropogenic

Selenium (Se) is a widely distributed trace element with dual (beneficial or toxic) effects for humans, animals, and plants. The availability of Se in the soil is reliant on the structure of the parental material and the procedures succeeding to soil for
