Latest Patents

One of Andrew's latest patents is focused on nanotextured metal powders for 3D printing of metals. This invention involves creating metal powder particles by removing material from their surfaces using wet chemical etching. The result is a nanoscale texturing that enhances the absorptivity of the metal powder particles to incident laser light while maintaining their flowability. The texturing features sub-wavelength characteristics at laser wavelengths ranging from 800-1100 nm. The particles are designed to be substantially spherical, with mean diameters between 10-70 μm.

Another notable patent is for an integrated dry gasification fuel cell system designed for the conversion of solid carbonaceous fuels. This integrated dry gas fuel cell (IDG-FC) includes a solid oxide fuel cell with an anode, cathode, and an electrolyte membrane. The system utilizes a conversion bed where carbon dioxide gas is introduced to convert carbon monoxide gas. Solid carbonaceous fuel is also provided to promote this gas conversion. The carbon monoxide serves as fuel for the anode, while air is supplied to the cathode to provide the necessary oxygen for oxidation, generating electric power. This innovative process operates without the need for water and utilizes an ionically selective solid oxide electrolyte membrane for oxygen supply.
