Fullerene

Fullerenes are one of only four types of naturally occurring forms of carbon (the other three being diamond, graphite and ceraphite). They are molecules composed entirely of carbon, taking the form of a hollow sphere, ellipsoid, or tube. Spherical fullerenes are sometimes called buckyballs, while cylindrical fullerenes are called buckytubes or nanotubes.
