第一篇
Graphene' s Superstrength Big technology comes in tiny packages.New ccii phones and personal computers get snialler every year, which means these electronics require even smaller components on the inside.Engineer; are looking for creative ways to build these components,and they'ye turned their eyes to graphene,a superthin material, made of carbon,that could change the future of electronics. This year's Nobel Prize for Physics has been awarded to Andre Geim and Kostya Novoselov from the University of Manchester,U.K.for the discovery of graphene.Graphdne isn't just small;it's "the thinnest possible material in this world"says Novosclov.iJe calls it a “wonder material".It’s 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 fingers,you'ci have no idea because you wouldn't 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 earboti,but only one atom thick.You don't have to look far to find graphene一it's all around you. If you want this high-tech wonder stuff,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 tape over the area. When you pull up the tape,you'll see that it pulls up a thin layer of some of the shading from your pencil. That layer is called graphite,one of the softest mninerals in the world. Now stick the same piece of tape on another sheet of paper and pull the tape up一there should be an even thinner layer,this time left on the paper. Now imagine that you do this over and over,until you get the thinnest possible layer of material on the paper. This layer would he only one atom thick,and you wouldn't be able to see it. Graphite is made of layers of graphene.So when you get to the thinnest possible layer, you've found graphene. Which of the following statements about graphene is true? A.It is visible to the human eye. B.It is possibly the thinnest material in the world. C.It can he used to make paper. D.Finding it demands time and money. [单选题]合环点两端电压相角差不超过(____)。
