Abstract
A method includes producing an isolation atmosphere in a phase changing area above a reactant liquid and then injecting a feed material into the reactant liquid. The feed material includes a carbon-bearing material. The method further includes maintaining the molecules of the injected carbon-bearing material and any reaction products in contact with the reactant liquid for a period of time sufficient to liberate carbon atoms from the carbon-bearing material or reaction products from that material, and place the liberated carbon atoms in an excited state. Liberated carbon atoms in the excited state are then allowed to traverse a surface of the reactant liquid and flow along a particle formation path through the phase changing area so that the liberated carbon atoms may phase change to the ground state while suspended in the phase changing area.
