Abstract

Carbon nanostructures are mass produced from graphite. In particularly preferred aspects, graphene is thermo-chemically derived from graphite and used in numerous compositions. In further preferred aspects, the graphene is re-shaped to form other nanostructures, including nanofractals, optionally branched open-ended SWNT, nanoloops, and nanoonions.

Claims

exact text as granted — not AI-modified
1 .- 22 . (canceled) 
     
     
         23 . A method of producing an open-ended single-wall carbon nanotube the method comprising providing a graphene, and providing energy to the graphene to thereby form the open-ended single-wall carbon nanotube. 
     
     
         24 . The method of  claim 23  wherein providing energy to the graphene comprises heating the graphene to a temperature of 200° C. and 600° C.
