US Patent 7550128 Method and apparatus for producing carbon nanostructures

A method includes liberating carbon atoms from hydrocarbon molecules by reaction with or in a reactant liquid and maintaining the liberated carbon atoms in an excited state. The chemically excited liberated carbon atoms are then enabled to traverse a surface of the reactant liquid and are directed across a collection surface. The collection surface and the conditions at and around the collection surface are maintained so that the liberated carbon atoms in the excited state phase change to a ground state by carbon nanostructure self-assembly.
