Swedish Academy of Sciences has awarded the research "revolutionary" of the two Russian scholars of the thinnest material ever created in a lab that will revolutionize electronics. Two unique prize: a recent discovery and an award winning one of the youngest in history "What is our invention? Would be like asking what's the use plastic." The scientist Andre Geim has just won the Nobel Prize for Physics with his colleague Konstantin Novoselov, both from the University of Manchester. From Stockholm, which awards the prize committee's surprise call to give him the news and ask what will the graphene, the new material that they have invented. He is speechless. "I do not know. It 's like a piece of plastic to make a man a century ago and ask what you can do. A little bit' of everything, I think." Graphene has been described by the Nobel committee in Stockholm as " the first material in two dimensions'. It is in fact so thin as to have virtually eliminated the size of the thickness. To reach a height of an inch must be superimposed on three million sheets of graphene. Its "plot" consists of a single layer atoms of carbon and if it is visible as a large sheet of honeycomb cells. "Graphene is thin, strong, light and yet dense, almost transparent and flexible," said the Nobel committee in the grounds of his choice. E ' consists of a very common element - carbon, an essential block of living things - and it is a good conductor of electricity. To say what can serve as a material - described by the two Russian scientists in Science in October 2004 - the only limit is fantasia.Schermi thin, much smaller than today's computers, solar panels, tools to get you to explore its gorges in our DNA sensors capable of picking up even individual molecules of poisonous gases are just some of the ideas put forward since 2004. But perhaps the most appealing to our imagination is that of wearable electronic devices such as t-shirts. Being flexible and lightweight, the graphene can in fact be treated as a fabric. And his property to conduct electricity makes it attractive for computer gadgets and television industry. To get to their discovery and Konstantin Geim departed from a peak of pencil (made of graphite) and an adhesive tape. But next to a kit so simple, they had to put all their knowledge. A so small in fact the materials cease to behave with the ordinary laws of physics and start to follow those of quantum mechanics. And to make sheets of graphene are, however, tools and equipment that can operate in infinitely small. The "new plastic" So do not invade our world from one day to the next. Contrary to the habits of the Nobel committee in Stockholm, this award came just a few years after the discovery in 2004. And while Geim (born in Russia but a Dutch national) is 51, Novoselov (citizen Russian and English) with its 36 years is one of the youngest Nobel history. From the Swedish capital did not fail to mention the aspect of "playful" of the two winners of doing science. It is no coincidence that ten years ago, Geim also won an Ig Nobel. Given the anti-Nobel, these prizes are awarded by Harvard University to research the most funny, entertaining, seemingly unnecessary and ridiculous. Geim won for its "flying frog": a small amphibian that within a magnetic field rose into the air. ELENA
