Finding of graphene deserves award of this year's Nobel Prize in Physics

Graphene is a recently found substance that is thinner, stronger and more conductive to electricity and heat than anything else known. The 2010 Nobel Prize in Physics, and also the $1.4 million dollar award that goes with it, were awarded to a duo of Russian scientists who found graphene. Experiments are being conducted by scientists around the globe to determine practical graphene applications that consist of replacing silicon in computer chips, ultra-definition screens and new materials as yet unknown.

Scotch tape assists to discover Graphene

Graphene was discovered by new Nobel laureates Andre Geim and Konstantin Novoselov at Manchester University. The NY Times accounts that while investigating the electrical properties of graphite, they tried peeling layers of it off with Scotch tape. A single atom thick of carbon is what they ended up with. The Times explained that a sheet of Graphene stretched over a coffee cup will support the weight of a truck bearing down on pencil point because of how thin and powerful it really is. Graphene is able to conduct electricity and create a ton of heat which may lead it to replacing silicon in computer chips. It would also be able to modify physics, change the way flat screen TVs are made and even become a pollution monitoring material.

Existence will never be the same with Graphene

Cable News Network talked to Geim who said graphene will change every little thing in life. It will change as much as finding plastic changed things. The material is two dimensional with the hexagonal array of carbon atoms. These atoms are arranged really specifically. Graphene is “fundamentally different” from three dimensional graphite because it is flexible. According to Graphene Industries, which works closely with Geim, two-dimensional materials like graphene give scientists access to materials of any dimension, including zero-dimensional atoms and one-dimensional nanowires. Cable News Network wrote that Geim said graphene can do countless amounts of things. It can never even be counted.

What exactly is next with graphene

Graphene is a common material throughout the world. Many laboratories are experimenting with it. One thing was discovered by researchers at the University of California, Berkeley. It was found, states PC World, that graphene is like a magnetic field when it is being stretched out. Knowing this about the substance can make it possible to build electronic devices differently. It will help to replace parts with it. Based on Science, technological innovation could be changing with a discovery in South Korea. Researchers figured out how to get sheets large enough to act as a touch screen much better than the ones we have now.
