Simple chemical processing converts graphite oxide into a porous graphene-like carbon material with exceptional surface area and electrical properties, according to a team led by researchers at the University of Texas, Austin (Science, DOI: 10.1126/science.1200770). The development could lead to commercial quantities of this inexpensive form of carbon, which the team has shown can be fashioned into high-performance supercapacitors—devices typically made from high-surface-area carbon. Unlike batteries, which are designed to store a relatively . . .
