Superfast airplanes through super tiny technology

Princeton engineers will study how fuel additives made of tiny particles of graphene can help supersonic jets fly faster and make diesel engines cleaner and more efficient. To create the graphene particles, the researchers remove carbon dioxide molecules from graphite oxide (top two molecules) which leaves a irregular bond pattern that creates a buckle in the otherwise flat graphene molecule (bottom molecule). This ridge prevents the graphene molecule from folding into ball.
