A fundamental advance was made at Rice University in Texas. The Second Strand A fundamental advance was made at Rice University in Texas. Smalley and co-workers developed a technique which enabled large metal clusters (with tens of atoms) to be studied for the first time

Graphite is known to consist of layers of hexagonally packed carbon atoms
