Hydrogen found to be essential to creating better graphene

Hydrogen found to be essential to creating better graphene: "Graphene, the 'wonder material' composed of single-atom-thick carbon sheets, is currently finding its way into a variety of electronic devices including computer chips, capacitors, transistors and batteries, just to name a few. It is typically created using a chemical vapor deposition process, in which carbon-containing gases are made to decompose on a copper foil substrate."
