ABSTRACT
In situ observation of the transformation of diamond nanoparticles (DNP) into onion-like carbon (OLC) was made during electron-beam irradiation inside an ultrahigh-vacuum transmission electron microscope at 300 kV with 8.5×1023 e/m2. 5 nm DNP changed into OLC within about 10 min of irradiation, while 20 nm DNP did not change to OLC but to graphite. Therefore, the size effect is critical to the formation of OLC. The mechanism of formation of OLC from DNP is discussed.

    The adsorption of C[sub 60] molecules on the surface of a rhenium ribbon heated to 1800 K is investigated quantitatively. It is found that the C[sub 60] molecules are adsorbed without reflection and then dissociate, and the carbon formed in the process is dissolved in the bulk of the rhenium to...
