Our world is constantly trying to find new and better materials to build things with. In 2004, the discovery of a stable graphene layer initiated a new frontier for construction and electrical products.
Graphene is a lattice exactly one atom thick. It has tremendous strength, and because of its properties it may pave the way for electrical devices that do not depend on metal or semiconductors. This has ramifications including: smaller size, strength of great proportion compared to its weight, and electrical conductivity which may require a lot less power.
Electricity is easier to control in graphene. Electrons also move faster in graphene than metal. Acid and alkali cannot break graphene chemically. Things wrapped in graphene are resistant to corrosion. Graphene may be used to build light weight fuel tanks for hydrogen cars. More responsive gas detectors could be built with graphene. Graphene batteries can store far more energy than lithium and they can be charged faster.
Graphene has been known for 50 years, but only in 2004 were Professor Andre Geim and his team successful in isolating a perfect graphene layer. Read more. http://john000.hubpages.com/hub/New-Graphite-Material-Graphene-One-of-Newest-Discoveries-in-Science
