US Patent 8119093 - C70 fullerene nanotube

http://www.freepatentsonline.com/8119093.html

This patent from Japan's National Institute for Materials Science claims a new type of nanotube structure based on C70 fullerenes. Claim 1 reads:

1. A C70 nanotube which is a thin line with a hollow structural portion made of a C70 fullerene molecule, wherein a wall thickness of the nanotube is in the range of from 1 to 500 nm, and an outer diameter of the nanotube is in the range from 200 to 1000 nm, wherein an inner diameter of the nanotube is linearly related to the outer diameter of the nanotube throughout the hollow structural portion.
