First Nanotubes, then Graphene and now new form of carbon schwarzites

UC Berkeley chemists have proved that three carbon structures recently created by scientists in South Korea and Japan are in fact the long-sought schwarzites, which researchers predict will have unique electrical and storage properties like those now being discovered in buckminsterfullerenes (buckyballs or fullerenes for short), nanotubes and graphene. The new structures were built inside …
