Title: Innovations of Jonathan Chavez in Nanoparticle Synthesis
Introduction
Jonathan Chavez is an accomplished inventor based in Grovetown, GA (US). He has made significant contributions to the field of nanoparticle synthesis, holding two patents that address environmentally important challenges. His innovative methods utilize ultrasound technology to create nanoparticles from bulk metals, including gold.
Latest Patents
Chavez's latest patents include a method for the direct formation of metal nanoparticles using ultrasound. This technique allows for the creation of nanoparticles directly from bulk metal by applying ultrasound to the surface in the presence of a two-part surfactant system. The implosive collapse of cavitation bubbles near the bulk metal surface generates powerful microjets, leading to material ejection. The liberated material is captured and stabilized by a surfactant bilayer, resulting in nanoparticles that can be produced regardless of the bulk metal form factor. This method is particularly applicable to the reclamation of gold from electronic waste streams.
Another notable patent is the direct formation of gold nanoparticles using ultrasound. This invention provides a green chemistry, aqueous method to synthesize gold nanoparticles directly from bulk gold sources. The process involves the ultrasonication of bulk gold in water with an alkythiol species and a quaternary ammonium surfactant. An organic bilayer forms on the surface of the gold, making it susceptible to material ejection from the collapse of cavitation bubbles. The ejected material is stabilized in solution and can be easily separated, allowing for the recovery of gold from sources such as SIM cards without prior manipulation.
