Researchers, led by Alexander Balandin at the University of California-Riverside, USA, have demonstrated that graphene - sheets of carbon only one atom thick - can also be an excellent heat conductor. Since the discovery of the material in 2004, researchers have been able to demonstrate that it is a good electrical conductor, as well as having good strength. It has also been surmised that graphene could show interesting heat conduction properties too, based on the behaviour of carbon nanotubes.
