有一种材料,导电性能比所有金属都高出不少,强度比钢铁强上百倍,导热性能超过我们所熟知的一切物质。它的厚度只有百亿分之三米,是人们能够制造出来的最薄的材料。然而,只要仔细检查铅笔,就能找到它的痕迹。这就是石墨烯,由碳原子构成的二维结构,也许将会把人类带入全新的太空时代和更快的信息时代的超级明星。我们这颗星球上所有的生命的基础是碳,我们使用的电能有2/3来源于各种碳的沉积;用来做为永恒见证的钻石是碳;最常用的书写工具铅笔,虽然名字里
There is a material, the electrical conductivity of all metals are much higher than the strength of a hundred times stronger than steel, thermal conductivity than we are all well known material. Its thickness is only three billionths of a meter and is the thinnest material that people can make. However, as long as the pen carefully examined, you can find traces of it. This is graphene, a two-dimensional structure made of carbon atoms that may bring humans into the new space age and a superstar of the faster information age. The foundation of all life on our planet is carbon. Two-thirds of the electricity we use comes from the deposition of various carbons. The diamonds used as eternal testimonials are carbon. The most commonly used pencils for writing instruments, though in their names
