Embodiment Construction

[0043] A typical nanoparticle production system can produce nanoparticles by feeding material into a plasma stream, thereby vaporizing the material and allowing the produced reacting plasma mixture to cool and condense into nanoparticles and composite or "nano-on-nano" -on-nano)" particles. The particles can then be collected for use in various applications. Preferred nanoparticles and "nano-on-nano" particles are described in US Application Serial No. 13 / 801,726, the entire description of which is incorporated herein by reference.

[0044] The present convex disclosure relates to both particles and powders. These two terms are equivalent, except that the singular "powder" refers to a collection of particles. The present invention can be applied to various powders and particles. Those skilled in the art will appreciate that the terms "nanoparticles" and "nano-sized particles" generally encompass particles with diameters on the nanometer scale, typically between about 0.5 nm...
