A group at the University of California, Los Angeles, has created microsupercapacitors using a simple DVD burner to forge the one-atom- thick sheets known as graphene on which these devices are formed, in arrays. Together with a battery, such supercapacitors could run a cellphone for days. And because an array is less than 10 micrometers …
