In 1907, the first light emitting diode (LED) was created by applying voltage to a silicon carbide crystal. Through the 1930s silicon use grew with the development of new chemical products, including silanes and silicones. The growth of electronics over the past century has also been inextricably linked to silicon and its unique properties.

2016-7-29 · Silicon Carbide is the only chemical compound of carbon and silicon. It was originally produced by a high temperature electro-chemical reaction of sand and carbon. Silicon carbide is an excellent abrasive and has been produced and made into grinding wheels and other abrasive products for over one hundred years.
A technique capable of making an object move and transporting it without generation of a current, and extracting mechanical work. As a result of diligent effort, the present inventors have found that by arranging two electrodes for generating an electric field for a dielectric body of a micrometer-size or the like in an insulating fluid such as oil, such that the central axes of the two

The chemical syol for tungsten is W which stands for wolfram. The name came from medieval German smelters who found that tin ores containing tungsten had a much lower yield. It was said that the tungsten devoured the tin “like a wolf”. Pure tungsten metal was first isolated by two Spanish chemists, the de Elhujar brothers in 1783.
