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 preferably comprises a quantity of a hydrocarbon compound. The method further includes maintaining the molecules of the injected 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 compound or reaction products 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.
