US Patent 7550129 - Faceted graphene nanofibers

This patent from Catalytic Materials teaches manufacturing a variation of carbon nanotubes in which the nanotube walls are faceted instead of cylindrical. Claim 1 reads:

1. A crystalline graphitic nanofiber consisting essentially of at least one uninterrupted, unbroken, substantially graphite sheet that is aligned substantially parallel to the longitudinal axis of the nanofiber and which has a substantially non-cylindrical multifaceted tubular structure, wherein when two or more of said sheets is present they are present as a tube within a tube structure and wherein the distance between graphite sheets is from about 0.335 nm to about 0.67 nm, wherein said substantially crystalline graphitic nanofiber has a crystallinity greater than about 95%.
