The physical-chemical properties of a synthetic gallophosphate molecular sieve, the 30-A supercage cloverite , have been assessed [18]. Instead of attempting to list the burgeoning number of fullerene publications, attention is drawn to the formation and characterization of fullerene-like nanocrystals of tungsten disulfide [19,20]. Preparation, characterization and utilization of carbon nanotubes have been the subject of a number of reports from several laboratories [21-27]. 

The rod-like nanoparticles that are commonly discussed in the scientific literature are carbon nanotubes. Carbon nanofibers (CNFs), which have a larger diameter, are also available. They are cheaper and are available in much larger quantities than carbon nanotubes. Ceramic nanotubes (e.g., zirconia, tungsten disulfide) or whiskers (e.g., silicon nitride, silicon carbide, alumina) can also be used.
