Research
Professor Harry Tuller is a world-renowned expert in electroceramics, a class of ceramic materials that enable technologies such as energy conversion, environmental sensing, electronics, and communications. Another research focus is solid-state ionics, which examines the movement of ions, or charged atoms, in solids such as ceramics. His research group models, processes, and optimizes energy-related devices such as sensors, batteries, and fuel cells as well as microelectromechanical (MEMS) systems.
Biography
Professor Tuller received a BS and an MS in electrical engineering and a doctorate in solid-state science and engineering, all from Columbia University. Before joining the DMSE faculty, he served as a postdoctoral research associate at Technion in Israel. He has published more than 500 articles, co-edited 15 books, and was awarded 33 patents. He is editor-in-chief of the Journal of Electroceramics and series editor of Electronic Materials: Science and Technology. He is also co-founder of Boston MicroSystems, a pioneer in silicon carbide-based MEMS technology and devices.
Key Publications
Chemical Control of Space Charge Barriers and Grain Boundary Resistances in Polycrystalline Ionic Conductors
Developed a way to selectively change the chemistry of grain boundaries—the tiny interfaces between individual crystals in a material, making it easier or harder for electrical charges to move across them.
Reactivation of chromia poisoned oxygen exchange kinetics in mixed conducting solid oxide fuel cell electrodes by serial infiltration of lithia
Extended the commercial viability of fuel cells and improved original performance despite long-term degradation of the metal oxide components. We recovered poisoned metal oxide surfaces by systematically controlling their acidity.
