Silicon - Element information, properties and uses | …

The credit for discovering silicon really goes to the Swedish chemist Jöns Jacob Berzelius of Stockholm who, in 1824, obtained silicon by heating potassium fluorosilie with potassium. The product was contaminated with potassium silicide, but he removed this by stirring it with water, with which it reacts, and thereby obtained relatively pure silicon powder.

Theoretical Prediction of the N−H and O−H Bonds …

Effective cleavage of the N−H and O−H bonds at “metal-free” centers has attracted considerable attention due to the fundamental and industrial importance. In this paper, we show by density functional theory calculations that the pure silicon carbide nanotube (SiCNT) can effectively cleave the N−H bond of ammonia and the O−H bond of H−OX (X = H, CH 3, and C 2 H 5).
