Graphenes Superstrength1 Big technology comes in tiny packages. New cell phones and personal computers get smaller every year，which means these electronics require even smaller components on the inside. Engineers are looking for creative ways to build these components，and theyve turned their eyes to graphene，a superthin2 material，made of carbon，that could change the future of electronics. This years Nobel Prize for Physics3 has been awarded to Andre Geim and Kostya Novoselov from the University of Manchester4，UK. for the discovery of graphene. Graphene isnt just small, itsthe thinnest possible material in this world， says Novoselov. He calls it awonder material. Its so thin that you would need to stack about 25,000 sheets just to make a pile as thick as a piece of ordinary white paper. If you were to hold a sheet of graphene in your fingers5，youd have no idea because you wouldnt be able to see it. Carbon is one of the most abundant elements in the universe. Every known kind of life contains carbon. Graphene is a sheet of carbon，but only one atom thick. You dont have to look far to find grapheme its all around you. If you want this high-tech wonderstuff6，all you need is a pencil，paper and a little adhesive tape. Use the pencil to shade a small area on the paper, and then apply a small piece of adhesive |
