Research focuses on the synthesis of novel nanostructure for a host of applications ranging from magnetic nanoparticles for energy applications to catalytic nanoparticles for organic synthesis.  Our magnetic work is focused on the synthesis and characterization of new nanomagnetic materials. Current high efficiency motors utilize rare earth elements which are expensive and have uncertain supply chains. Our group has developed a new class of magnets which contain no rare earths. Our goals are to develop this new magnet system for use in renewable energy applications such as power generators and electric motors.  Chemical engineering comes into play because all too often a promising synthesis is never moved into commercialization application due in part to the low yield and/or lack of scalability of the synthesis method.  All our processes focus on techniques which can be converted into continuous flow processes.  We utilize not just simple precipitation but also high pressure supercritical fluids.  We focus on magnetic elements of iron, cobalt, and nickel, and catalytic elements of platinum and palladium.
