How To Cure Kidney Cysts

Physics Nobel 2010 to two Russian scientists for their work on graphene

Andre Konstantin Geim and Novoselov 2010 Nobel Prize in Physics for his work on graphene and Quantum Physics
In 1997, Geim managed to levitate a frog in a magnetic field, "an ingenious way of illustrating the principles of physics," said the Nobel Foundation. In those experiments with the frog, received in 2000 IgNobel of Physics, one of the Nobel prizes that are considered alternative and given 20 years for those jobs "that first make you laugh and then think."

first .... Good start having fun with physics levitating frogs and ten years later won the Nobel ...

The winners, Geim (Russia, 1958) and Novoselov (Russia, 1974) have shown that carbon in the flat configuration has extraordinary properties originating in the world of quantum physics

The figure shows an almost perfect graphene network, one atom thick formed by atoms carbon in a hexagonal configuration

Graphene is a new material, extremely thin and strong that, as a conductor of electricity, it behaves like copper, and as conductor of heat than any other known material . It is almost completely transparent and so thick that even the helium gas atom smaller, can pass through it.

Geim, of Dutch nationality, and Novoselov, British and Russian scientists at the University of Manchester (United Kingdom), graphene obtained from normal graphite, the material from the mines of the pencils and found a picture of a just one atom thick. Many thought then that it was impossible for a material and be stable. However, from the work of these two scientists, physicists can now study a new class of two-dimensional materials with unique properties.

Graphene also has a wide variety of applications, including the production of new materials and electronic devices advanced.

graphene transistors may be substantially faster than current silicon, which may make computers more effective.

Also, as is transparent and a good driver, are emerging applications of electronic screens and even solar panels.

The Nobel Prize in Physics has been awarded since 1901 (except in specific years: 1916, 1931, 1934, 1940, 1941 and 1942) and is worth 10 million kronor (1.1 million euros).
