Pellet (1 of 3) (IMAGE) Rice University Caption Researchers at Rice University consolidated functionalized graphene at room temperature by first crushing graphene powder and then pressing it into pellets. Chemically altering the graphene powder with carbon, oxygen and hydrogen provided a way to bind the graphene into a three-dimensional solid under pressure.
