1. A method for producing carbon nanostructures, the method including:
- (a) producing a collection atmosphere in a collection area above a reactant liquid;
(b) injecting a feed material into the reactant liquid, the feed material comprising a quantity of a first type of hydrocarbon compound;
(c) maintaining the hydrocarbon molecules of the first type of hydrocarbon compound and any reaction products in contact with the reactant liquid for a period of time sufficient to liberate carbon atoms from the hydrocarbon molecules of the first type of hydrocarbon compound or reaction products and place the liberated carbon atoms in an excited state; and
(d) enabling the liberated carbon atoms in the excited state to traverse a surface of the reactant liquid and flow along a collection path through the collection area so that the liberated carbon atoms pass over a collection surface in the collection area under conditions in which the liberated carbon atoms are enabled to phase change to the ground state on the collection surface.

Abstract
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.
