Is this a trigger for revolution in science! Graphene is also known as Graphene which has an incredible super strength of 20 times stronger than Diamond and 200 times stronger than steel and 6 times lighter. Just as the contents of a pencil are stronger than steel and diamond the difference between graphite is a type of carbon that is flammable and easily destroyed when subjected to pressure. However, by peeling and isolating graphite the contents of the pencil become a thick atomic layer using ordinary adhesive tape.
Graphene is also very conductive - good for conducting electricity and heat. If that isn't awesome enough, graphene is almost transparent, impermeable to gas, and has properties - which scientists say - are easy to change.
As is known, diamonds and graphite as used for the same pencil-based contents are carbon. The reactions that shape them become determinants of differences and values of both. Diamonds form at a depth of 150 kilometers, with a pressure of about 5 giga pascal with a surrounding temperature of 1,200 degrees Celsius. Make it a super-hard object. Even Diamond, which means diamond, comes from the Greek word adamas which means "indestructible".
Two Russian-born scientists, Andre Geim and Konstantin Novoselov, won the Nobel Prize in 2010. Directing the discovery of a 'magic material', which is destined to change human life in the 21st century: graphene or graphene.
Graphene is a carbon fiber which is only composed of one layer of carbon atoms arranged in a lair of honeycomb. At present, a research laboratory in South Korea may have made a leap from theory to practice, by developing ways to synthesize graphene, which has the potential to be used on a commercial scale. Substance, "perfect atomic lattice" has an interesting ability, which makes it potentially used in various industries and for almost all purposes.
Graphene is one form of carbon allotrope, the basis of all life on Earth. Carbon allotropes that are better known include diamonds and graphite. What makes graphene unique is its thinness - it has a thickness of only one atom, which is carbon arranged sideways on a lattice that resembles a honeycomb and is thought to be the thinnest semiconductor material in the world.
Its flexibility to make graphene can be used to make a device that is flexible or usable. "Graphene has a lot of potential, especially in terms of industrial applications for optical and electronic devices," said Ping Sheng, a professor of nanoscience at the Hong Kong University of Science and Technology. The only obstacle is the quantity. If graphene could be produced on a large scale. "If so, that would be a major breakthrough."
Besides extraordinary thinness, another advantage is its light weight. Graphene can be used to make ultra-light components for - for example - the aviation industry, which dramatically reduces the weight of the aircraft - and thus significantly increases fuel efficiency without sacrificing its strength. Extraordinary!
Graphene is even touted as the future of condoms. The Bill and Melinda Gates Foundation last year provided a $ 100,000 grant to fund the development of graphene contraceptives.
Challenges in Graphene Production
One of the important challenges of producing graphene is the way the material is developed. The material must still be isolated using the Scotch Tape technique, isolated from graphite - which is used in pencil rods with complex and complex techniques using tape. Also the conductivity is irreversible, which means that as a semiconductor, graphene is useless, even though researchers experimented with the substance to find ways to overcome this problem. One possible solution is to use a chemical process.
If this deficiency can be overcome, graphene can be used in a variety of devices instead of superfast silicon transistors, which have reached their maximum capacity. Graphene has the capability of a hundred times the mobility of silicon electrons. Another limitation comes in the form of production: currently it can only be synthesized in the form of small crystals. Although this is enough for researchers to test the properties and understand the benefits, it is not enough to produce it for mass commercial use.
Until now, public funding and the private sector actively explored the substance. The European Union poured US $ 1.3 billion in research funds that have the potential to change it so that it can be used in various sectors, including electronics, energy, health and construction. The funds are to be used in 2013 to 2023. Then, Samsung Advanced Institute of Technology last week announced it had developed a "breakthrough synthesis method" in the production of graphene, and hoped that it would pave the way for the commercialization of these materials. The results were published in the scientific journal Science.
Samsung sees graphene as the "perfect ingredient" for next generation devices, and breakthroughs that can have major implications for commercial production. "This is one of the most significant breakthroughs in graphene research in history," the researchers said in a statement
remove it by Samsung. "We hope this discovery can accelerate the commercialization of graphene, which could open the way for a new era of consumer-based electronic technology."
In partnership with Sungkyunkwan University, the Samsung Advanced Institute of Technology has pioneered gafena on a wafer layer scale. Previously, one 30-inch diameter graphene had been produced. But it feels less effective. Not yet revealed, whether Samsung plans to make a breakthrough in the process of mass synthesis, a step that will quickly accelerate the adoption of graphene in everyday use.
However, according to Sheng, it will not be long before the process is carried out widely. "I think it is impossible for them (Samsung) to hide it for a long time, even if they want it ... There will be many factories around the world doing the same thing," he said.
