You can make graphene out of almost anything. Even Girl Scout cookies. A sheet of graphene made from one box of shortbread cookies would cover nearly three football fields. And talk about profit—at $250 for a two-inch square, a box could earn $15 billion.
In a newly published study, researchers at Rice University describe how graphene—a single-atom-thick sheet of the same material in pencil lead—can be made from just about any carbon source, including chocolate, grass, a cockroach leg, dog feces, and Girl Scout cookies.
The scientists say the experiment is a whimsical way to make a serious point: that graphene—touted as a miracle material for its toughness and conductivity since its discovery in 2004—can be drawn from many sources.
