Graphene is a thin sheet of carbon atoms that bond to their neighbors to form a chicken-wire-type lattice precisely one atom thick. That doesn't sound too spectacular, but it has scientists in a tizzy. It has been considered for everything from DNA sequencing, to water sterilization systems, to electronics. Although each possible use requires more testing, the electronic applications give the material the most hurdles to jump before it can be declared practically useful. A little while ago, it sailed over one more bar. [io9]
It's all great, but has it actually been used in anything commercially available yet? It's wonderful having all this miraculous materials and fuel substitutes and stuff, but it takes years and years, if ever, for them to actually become available to the public in every day items.
