Well, after a while back to put an article in my blog ... Many will think that I had forgotten my blog. But no! Do not be so easily librareis me = D
The graphene is a flat sheet structure of an atom thick, composed of carbon atoms densely packed in a crystal lattice in the form of honeycomb through covalent would be formed from the superposition of the hybrid sp2 bonded carbons. Come on, a material that you shit. Indeed, the Nobel Prize in Physics 2010 was awarded to Andre Geim and Konstantin Novoselov for his groundbreaking discoveries dimensional material graphene.
The graphene has properties that make it a unique material on our planet. It developed the first material that has two dimensions, is the finest and the toughest at the same time. The best conductor of heat, conduct electricity more efficiently than copper, is virtually transparent and is so dense that no gas can pass. And, more importantly, is a potential replacement for silicon chips in computer science.
Theoretically, graphene was at the head of scientists for decades, and it was not until 2004 when researchers at the University of Manchester achieved two-dimensional crystals of the material. Since then, several research teams have published advances that come to its practical application. For example, in April, scientists at the University of Texas managed to create a graphene sample of an inch in length. (Until then, there had been micro-sized).
Besides size, another challenge is to create sufficient quantities for industrial use. Several teams around the world work with various methods to achieve it. And they are getting interesting achievements. For example, in December 2008 IBM announced graphene transistors 26 GHz.
But where else will the field to highlight, in my opinion, will be on notebooks. The most tangible and immediately you will notice is that it will solve the problems to achieve total connectivity call: you can not load the whole day with the PC, your phone has a screen too small and the processor speed does not always have the joy wanted.
is that this new material is almost everywhere, but "packaged" in a way that does not perform so spectacularly: we had coal (carbon with amorphous structure), diamonds (crystal structure) and graphite (a form which includes sheets atoms). But we had graphene. Until, in 2004, Andre Geim and Kostya Novoselov, University of Manchester (UK), broke one of these sheets in the least scientific ever. So, not surprisingly, have received the 2010 Nobel Physics.
In his laboratory to study the graphite heat stuck on the sample and tore to remove the surface layers full of impurities. But Geim came up one day looking debris, and discovered that sometimes I could start a separate layers one atom thick that form graphite. So, I got graphene. So Novoselov and he founded Graphene Industries and no longer engage in conduct electrons at the university, but expensive cars on the street, it's more fun.
But I hope they go ahead with this material if it is all true (but rarely has not hit ... it is even cheaper)
