Researcher

 

Dr. Frederick F. Stewart is manager of the Biological and Chemical Processing Department at the Idaho National Laboratory. He leads a team of 30 to 40 researchers in the biological and chemical sciences.  In his current position, he is responsible for technical oversight of research in electrochemical processing, membranes and filtration, chemical synthesis, energy storage materials, computational methods, catalysis, supercritical fluid processing, microbiology, extremophilic organisms, and biomass processing and characterization. His research interests are membrane separations and polymer synthesis where he has been active for over 20 years. Specifically, he is published in the area of phosphazene chemistry and has established methods to functionalize these materials and form them into membranes for harsh chemical separations, such as flue gas carbon capture. He has also developed these materials as lithium battery electrolytes and electrodes. He has published > 90 journal articles, conference proceedings papers, and invited book chapters. Additionally, he has chaired the North American Membrane Society meetings in 2003 and 2013, as well as the 2012 Membranes, Materials and Processes Gordon Research Conference. He earned his Ph.D. in organic chemistry from Montana State University. Since 1997 he has been an adjunct assistant professor of chemistry for the University of Idaho. In 2013 he was honored with an R&D 100 Award with Aaron Wilson and Mark Stone for their work in switchable polarity solvent forward osmosis.
