Graphene, a material with remarkable electrical and thermal properties, can now be made in small batches, using a common kitchen blender. The substance is composed of sheets of carbon atoms, just one atom thick. The material could revolutionize the world of electronics through its unique properties, including flexibility. The "lead" in pencils is actually made with graphite, which is composed of sheets of graphene, piled together. When a person writes, this graphene rubs off on the paper, leaving a mark. It is possible to create a single layer of graphene using just a pencil and adhesive tape. The Nobel Prize in Physics went to Andre Geim and Konstantin Novoselov for this discovery. The prize committee wrote, "As a conductor of electricity [graphene] performs as well as copper. As a conductor of heat it outperforms all other known materials. It is almost completely transparent, yet so dense that not even helium, the smallest gas atom, can pass through it."
