What is graphene and what uses does it have for technology?
Carbon , one of the most important chemical elements of nature, is present in all living beings and is the source from which is obtained the graphene . This material originates when tiny carbon particles are grouped very densely into sheets of two very fine dimensions, the size of an atom, and hexagonal cells. Where do you get your raw material? Because something that is found abundantly in nature, especially in countries like China and Brazil, we refer to graphite. Yes, the same product that is used to make that pencil that you used when you went to school, is also used to make a wide range of other products. Origins of grapheme Graphene is not a new invention, it has been known since the 30's. Already in 1949 the Canadian physicist, Philip Russell Wallace , had calculated for the first time its structure. However, it was only at the beginning of this century that the ore became fashionable, largel...
