Class Information
Number: 977/845
Name: Nanotechnology > Manufacture, treatment, or detection of nanostructure > For carbon nanotubes or fullerenes > Purification or separation of fullerenes or nanotubes
Description: Subject matter wherein the process or apparatus is adapted to extract the fullerene or nanotube from the material that accompanies the growth process (e.g. residual catalyst, amorphous carbon, graphite) or to sort or divide the fullerene or nanotube based upon their physical or chemical properties (e.g. separation by size, chirality, etc.).
