Abstract:
A method for creating nanoparticles directly from bulk metal by applying ultrasound to the surface in the presence of a two-part surfactant system. Implosive collapse of cavitation bubbles near the bulk metal surface generates powerful microjets, leading to material ejection. This liberated material is captured and stabilized by a surfactant bilayer in the form of nanoparticles. Nanoparticles can be produced regardless of the bulk metal form factor. The method is generally applicable of metals and alloys. The method can be applied to an environmentally important problem, the reclamation of gold from an electronic waste stream.

Claim (Index 4):
The method of  claim 1 , wherein the emulsion-forming surfactant comprises a quaternary ammonium salt.
