Bend it,Charge it, Dunk it- Graphene

Graphene is pure carbon in the form of a very thin, nearly transparent sheet, basically one atom thick. It is remarkably strong for its very low weight (100 times stronger than steel ) and it conducts heat and electricity with great efficiency., it was first produced in the lab in 2004.Because it is virtually two-dimensional, it interacts oddly with light and with other materials.Technically, graphene is a crystalline allotrope of carbon with 2-dimensional properties. In graphene, carbon atoms are densely packed .If we stack layers of graphene on top of one another they form graphite, which is found in every pencil lead. In fact anyone who has drawn a line with a pencil has probably made some graphene.

Properties-a. Very good conductor of electricity and heat
                 b. 200 times stronger than steel
                 c. So thin that a single ounce of it covers 28 football fields
                 d. Highly flexible
                 f. Extremely light
Use-In 2011, a battery that incorporated Graphene and Silicon was built. This battery stayed
charged for more than a week and recharged in just 15 minutes.
This material can change the electronics industry using in flexible devices, supercharged
quantum computers, computers that can interface with the cells in our body.
Advancement in Graphene will lead to touch screen electronics that could make cellphone
as a thin piece of paper and foldable enough to slip into a pocket. 
             Truly Graphene is the material of tomorrow. If used extensively it can make a better world of living. By its extensive use, we can overcome the use of plastic and again hope for the coming generations to exist longer. Now, the large scale use of graphene can only save our beautiful nature!!!!!
