Part Five
Selected
Applications: 1991 - K3C60 synthesized - it is a conductor which becomes superconducting below 18K - Rb3C60 is superconducting below 45K
1991 - Buckytubes discovered - they are capped at the ends
1991 - Conducting films of C60 and C70 are prepared 1992-93 - Buckyballs as lubricants - work best at 100C, low humidity and inert environments 1992 - Organo-bucky compound exhibits magnetic behavior 1992 - U@C28 made - stabilization of very small fullerene - result of work on shrink wrapping metals 1992 - Soot on exposure to electron beams gave rise to nested spheres of fullerenes, e.g. C600, which is C60 nested in C540 1992 - Better methods developed for separating fullerenes 1992 - La@C82 treated theoretically

1992-93 - Superconducting properties of buckides require new theory of superconductivity 1992-93 - Buckyballs squeezed to diamonds at room temperature and 2/3 the pressure needed to produce diamonds from graphite 1992-93 - Tubes heated in presence of lead open up at the ends and draw molten lead into the tube - can they be used as molds for very thin (2-4 nm) wires?
1993 - He and Ne compounds found with the He and Ne inside the cage - cage appears to open a window to release the He or Ne atoms
1993 - Metallocarbohedranes prepared from soot 1993 - Lanthanum carbide sealed in a fullerene cage - not affected by moisture, as it is in the open air - buckyjars? 1993 - C70 shown to carry electrons across membranes - useful in photosynthetic and solar energy research
