Graphene is sometimes described as being two-dimensional, or 2D, which is probably more a reflection of the enthusiasm people feel about the material rather than a statement of fact since graphene is actually one atom thick.
It may only be one single atom, but it’s still there, which means that graphene is, in fact, three-dimensional.
Another interesting thing about graphene is that the naturally occurring composite mineral it’s extracted from – graphite – has been in use for thousands of years in such things as ceramic paints, and it’s been used in pencils for decades. But only now has graphene been extracted from it and suggested for a wide array of applications. [Read more…] about Graphene: A primer on the miracle material
