He is a research scientist from Idaho National Laboratory (INL) with extensive experience in the fields of materials electrochemistry as applied to reactive and refractory metals, process metallurgy, synthesis and characterization of high-temperature metals and materials, energy-efficient manufacturing processes, and materials recycling. While working at Bhabha Atomic Research Center, India, he developed an entirely new (molten salt based) process flow-sheet for the production of vanadium metal with a view to fabricate a self-powered beta detector. He also worked on the development of a new high-temperature process for the production of commercial-grade zirconia and silica powders from the indigenously available zircon mineral. His other projects have been aimed at recovering valuable materials from waste, secondary resources, and lean ore bodies. His team could successfully develop a technology for the conversion of Zr-2.5Nb alloy scrap to high purity zirconium crystal bar by van Arkel de Boer process. This technology can be adopted to successfully transform the alloy scrap into high purity zirconium crystal bar, a metal of significant importance to the nuclear energy program. At the University of Cambridge, he worked on the process optimization studies pertaining to the preparation of titanium metal and its alloys by a novel molten salt electrochemical process. He developed a preparative process for titanium-lanthanum alloy from their mixed oxides. At the Massachusetts Institute of Technology, he worked on a high-temperature electrochemical process to generate oxygen from the lunar regolith. This is one of the two technologies shortlisted by NASA for its eventual deployment to produce breathable oxygen from in situ (lunar) resources. At INL, the scientific underpinning of his research activities has been to study the behavior of metals and materials under a given set of conditions. His diverse research pursuits include materials electrochemistry, energy-efficient manufacturing processes, and materials recycling.
His areas of expertise include synthesis, structure, experimental thermodynamics, physical and chemical properties of intermetallic compounds containing rare earth metals, anomalous behavior of 4f-electron systems, magnetostructural phase transformations, physical properties of ultra-pure rare earth metals, caloric materials and systems, mechanochemistry, mechanically induced solid state reactions and mechanochemical transformations, and relationships between composition, structure, physical and chemical properties of materials. He is a distinguished professor of Materials, Science, and Engineering at Iowa State University, and is an FWP leader and faculty scientist at Ames Laboratory. He is a member of the Materials Research Society, Royal Society of Chemistry, and International Centre for Diffraction Data. He has his doctorate in inorganic chemistry and a bachelor’s and master’s in chemistry (with distinction), both from L’viv State University, L’viv, Ukraine.
