Welcome

Dr. Jason D. Nicholas PhotoWelcome to the Solid State Ionics Laboratory at Michigan State University! We develop new functional materials, processing routes, characterization techniques, and high-performance devices for energy-related applications. Presently we are focused on a) mechano-chemical coupling in electro-chemically active solids, b) high-temperature ceramic to metal seals, c) nano-composite Solid Oxide Fuel Cell electrodes, and d) strain-engineered thin film properties. Some of our past accomplishments include publication of the world's most highly cited "ceria sintering aid" paper,1 development of the world’s most highly cited nano-composite Solid Oxide Fuel Cell electrode model (the SIMPLE model),2-4 development of a new Ni-Ag stainless steel to ceramic brazing technique,5 and development of a new in situ, electrode-free bilayer curvature relaxation technique for measuring oxygen surface exchange coefficients as a function of simultaneously measured stress state.6 Please check our Publications, Google Scholar, or ResearchGate for information on our publications. Thanks for your interest in our group!
