Latest Patents

One of his latest patents is titled "Superparamagnetic nanoparticles and nanocomposites." This invention is directed to the syntheses of superparamagnetic nanoparticles and the incorporation of these nanoparticles as the magnetic component to form a strongly magnetic nanocomposite. The superparamagnetic nanoparticles possess no hysteresis and are too small to support eddy currents. The invention utilizes a ligand exchange procedure to produce aminated nanoparticles that are then cross-linked using epoxy chemistry. The result is a magnetic nanoparticle component that is covalently linked and well separated. By employing this 'matrix-free' approach, it is possible to substantially increase the magnetic nanoparticle fraction while still maintaining good separation, leading to a superparamagnetic nanocomposite with strong magnetic properties and low magnetic losses.

Another notable patent is "Direct formation of metal nanoparticles using ultrasound." This method creates 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. This liberated material is captured and stabilized by a surfactant bilayer in the form of nanoparticles. The method is generally applicable to metals and alloys and can address environmentally important problems, such as the reclamation of gold from electronic waste streams.
