A Catalyst article about buckytubes, a type of carbon nanoparticle.The allotropes of carbon —diamond, graphite and buckminsterfullerene (bucky balls) — are well known. Now scientists are working on buckytubes. These are based on elongated tubes formed from sheets of hexagonally-linked carbon atoms, capped at both ends with carbon pentagons. These tubes can be as little as 1 nanometre (10–9 m) in diameter. Although scientists have known about buckytubes since the 1960s, it was only in 1992 in Japan that Sumio Iijima first managed to make them in large quantities.
