Prabhat Tripathy

Prabhat Tripathy is a research scientist with more than 25 years of research experience in the field of materials chemistry. His areas of expertise include process metallurgy of reactive and refractory metals, high temperature electrochemistry, synthesis and characterization of advanced materials, energy-efficient manufacturing process, and chemical processing of waste (including nuclear) materials as well as lean ore bodies. He earned his M.Sc. (Chemistry), M. Tech. (Materials Science & Engineering) and Ph.D (Chemistry) degrees from Utkal University (Bhubaneswar, India), Indian Institute of Technology (Kharagpur, India) and University of Mumbai (Mumbai, India) respectively. Right after obtaining his M.S. degree, he joined Bhabha Atomic Research Centre (Mumbai, India) and subsequently spent stints at the University of Cambridge (UK) and Massachusetts Institute of Technology (USA) before joining Idaho National Laboratory. The scientific underpinning of his research career has been to understand metals and materials, through the application of novel techniques and to develop technologies/methodologies to effectively utilize them for commercial exploitations. Some of his distinguished research works include development of (1) monolithic inert anode materials for deployment in extreme environments (2) a hydriding-cum-dehydriding process to recycle critical elements (3) a highly effective surface modification technology for structural alloys to mitigate hydrogen embrittlement and stress corrosion cracking (4) an electrometallurgical process for the preparation of near-net-shape metallic components directly from their oxide intermediates (5) a new process flowsheet for the production of high-purity vanadium metal for the fabrication of self-powdered beta detectors (6) modified version of the Van Arkel-de Boer process to grow zirconium crystal bar from Zr-2.5Nb alloy scrap feed, and (7) a high temperature chemical process to produce capacitor-grade tantalum metal. To date he has forty-one invention disclosure records, four granted U.S. patents, fourteen pending patent applications, two books (as a co-editor), one published article in a book, two technology development articles in a newsletter/blog and one hundred six publications including peer-reviewed papers, conference proceedings/presentations and technical reports to his credit. Exclusive licenses pertaining to four of his technologies have been purchased by an Arizona-based company for deployment in mining industry. Additionally, his research in materials electrochemistry has resulted in the discovery of a robust monolithic anode material not only for reprocessing used nuclear reactor fuels but also for producing rare earth metals/alloys and recovering critical elements from a variety of waste materials including electronic wastes. The identification of the new anode material has solved one of the U.S. Department of Energy's long-standing unmet needs pertaining to spent fuel treatment. In addition, he has worked on other potential anode materials which have shown early promises for their possible deployment as cost-effective anodes in both civilian and defense applications. He holds an adjunct professor position in the Materials Science and Engineering Department at the University of Utah. He has been organizing an international symposium, titled, “High Temperature Electrochemistry" since 2013 and guest edited a special issue of Journal of Metals , published in October 2020. He is actively pursuing collaborative research programs with researchers from national laboratories and U.S. universities. He also acted as a consultant on three projects. Outside work, he enjoys traveling, reading biographies, watching documentaries and volunteering time to mentor high school students and junior colleagues.
