Thanks, dxb, for that link. ...and Harry Kroto (University of Sussex, UK; non-NSF funded) shared the 1996 Nobel Prize in Chemistry for the discovery of "buckminsterfullerene." Friend of yours? :-)

It says buckytubes are the strongest materials known; I immediately wondered if that meant stronger than diamonds. Upon second thought, though, I realized that diamonds are known for their hardness, which might not necessarily equate with strength.
