For dispersing nanoparticles in oil, the planetary ball mill method was used. The stability of fullerene nanoparticles in oil was reported to be acceptable, as after 720 h, there were no precipitation observed. It was also pointed out that fullerene resulted in the lowest thermal conductivity increase amongst all other carbon nanomaterials.

The solgel process is a more chemical method (wet chemical method) for the synthesis of various nanostructures, especially metal oxide nanoparticles. In this method, the molecular precursor (usually metal alkoxide) is dissolved in water or alcohol and converted to gel by heating and stirring by hydrolysis/alcoholysis. Since the gel obtained from the hydrolysis/alcoholysis process is wet or ...
