✦ Synopsis

We present a study of the heat treatment of carbon soot generated by an electric arc using graphite electrodes and run in a low inert gas helium pressure. This carbon soot has been incompletely characterized; primary results indicate properties distinct from other carbons. Heat treatments from 50@24OO"C were applied. At 17OO'C a glassy carbon material is obtained, but above 2000°C the generation of multilayer closed graphitic particles was observed. The size of the closed shell graphitic particles is very small (3-10 nm). These results suggest that a macroscopic quantity of fullerene-related particles, as well as short nanotubes, may be obtained by a simple thermal treatment of fullerene black.

The electric arc method of fullerene preparation leaves about 90% of the carbon as insoluble soot. Unprotected storage of CbO also leads to insoluble carbonaceous material. This "fullerene black" has been characterised with respect to its structural, electron spectroscopic and chemical properties. C

## Abstract High temperature annealing in a dynamic vacuum has been utilised to induce the growth of duplex oxide over the whole surface of stainless steel specimens. It is found that duplex oxide grows at a rate which does not obey a simple power law. The oxidation kinetics and oxide morphology ha
