2010 NOBEL PRIZE IN PHYSICS NOBEL PRIZE IN CHEMISTRY

Russian physicists Andre Geim and Novoselov Konstantin won the Nobel Prize of Physics 2010 for his groundbreaking experiments with graphene , a powerful form of carbon material that promises transform the way in which today are manufactured electronic and computer products.



The graphene is an outdoor structure, in fact, a few decades ago, it is clear from the graphite (eg, mining of a pen). However, there were difficulties in isolating individual layers in order to study it. That is what they managed to successfully Andre Geim and Novoselov Konstantin .

Why is it so important graphene ?

The graphene has the form of a thin slab of ordinary carbon, the thickness of just one atom, which has excellent properties: high strength, transparency, and extreme flexibility.

As conductor of electricity, graphene perform as well as copper to transmit power . It is extremely thin and extremely strong. And best of all, it's made of carbon the basis of all life on Earth, an element that can be easily found in any country in the world.

What makes it so important to the investigation of graphene is the possibility of replacing silicon currently used in the manufacture of all computer chips, and on which rests all information-related industries, and much of the technology .

Although experiments Geim and Novoselov also have theoretical implications, including the ability to study a new class of two-dimensional material with unique properties, its evidence and findings open the way for a wide range of practical applications.


Graphene is a hexagonal lattice like a honeycomb, made of carbon atoms

is believed that graphene transistors , for example, would be much faster than current silicon transistors, resulting in more efficient computers. And less expensive, since the carbon is a readily available material. Contamination would also be less than that of silicon-based products.

But also, as the graphene is transparent and a good conductor, is ideal for producing flexible touch screens, light panels folding or even solar panels .

When combined with plastics, the graphene can turn them into conductors of electricity while making them more resistant to heat and more mechanically robust. This capability can be used in new super-strong materials, but at the same time are slim, elastic and lightweight. In the future, satellites, airplanes, and cars may be made of such materials include the graphene .

Konstantin Novoselov , barely 36, first worked with Andre Geim , 51, as a PhD student in the Netherlands, although both were born and began his career in Russia Physics.

continued to work together United Kingdom, where they are now professors at the University of Manchester . The 2010 Nobel Prize , consisting of about 1 million euros, is due to his incessant experiments and contributions to the development of research on this new material, rather than an investigation or experiment in particular.

Geim and Novoselov successfully managed to produce, isolate, identify, and characterize the graphene , a task performed better than any other scientist, according to the Royal Swedish Academy of Sciences, responsible for ruling winners Nobel Prize in Physics every year.
