Abstract:
1. Stoichiometric-nanostructured material produced through the steps comprising: generating a plasma; forming an “active volume” through introduction of an oxidizing gas into the plasma, before the plasma is expanded into a field free zone, in a region in close proximity to either (1) a zone of charge carrier generation, or (2) a region of current conduction between field generating elements, including the surface of the field generating electrodes; and transferring energy from the plasma to a precursor material or materials and forming in the “active volume” at least one of stoichiometric-nanostructured material and a vapor that may be condensed to form a stoichiometric-nanostructured material; wherein the stoichiometric-nanostructured material is cerium oxide and has a surface chemistry with the value of the zeta potential greater than 20 mV.
