Latest Patents

One of his latest patents is the "Pulsed-field differential mobility analyzer system and method for separating particles and measuring shape parameters for non-spherical particles." This invention provides a method for extracting shape information for particles with similar shapes using a tandem differential mobility analyzer (DMA) and a pulse field differential mobility analyzer (PFDMA) system. The process involves generating a steady-state aerosol concentration, passing aerosol flow through a bipolar charger, and measuring mobility as a function of electric field by varying the duty cycle of the pulse in the PFDMA system. This method allows for the separation of particles based on shape by adjusting the duty cycle of the pulse.

Another significant patent is the "Method of producing metal particles by spray pyrolysis using a co-solvent and apparatus therefor." This innovative spray pyrolysis method produces pure metal and/or metal oxide particles using a mixture of a carrier gas and a solution of a metal salt precursor, water, and a co-solvent reducing agent. The method is designed to work with various metals, including Fe, Co, Ni, Cu, Zn, Pd, Ag, and Au, and utilizes low-carbon numbered alcohols as co-solvents.
