Graphene gains nearly perfect liquid status
Scientists have found the electrons in a layer of carbon atoms can become a strongly interacting swirling soup

Some things always hold true — the amount of time it takes to find your keys, for example, depends on how late you are. Similarly, the rate that electrons collide in a given material is closely linked to its temperature. But graphene — a sheet of carbon that’s only one atom thick — doesn’t conform to such rules. Over a wide temperature range, graphene’s electrons should become a strongly interacting swirling soup, scientists report online July 6 in Physical Review Letters.
That finding sug...
