Colin Wolden

Professor, Chemical and Biological Engineering

Colin WoldenOur research interests are focused on the synthesis of nanostructured materials and their application to solving challenges in the areas of renewable energy and sustainability. Synthesis techniques include both vapor deposition (sputtering, CVD) and solution processing (reactive precipitation, electrodeposition, etc.). A central theme is developing novel processing techniques that impart nanoscale control while retaining high rate for the efficient synthesis of mesoscale structures (5 – 500 nm). The materials we synthesize serve as integral components in thin film photovoltaics, solid state batteries, and membrane reactors. Investigation of these processes is guided by detailed reactive flow modeling and experimental measures of both homogeneous and heterogeneous kinetics. In-situ process diagnostics and ex-situ materials characterization are used to gain a fundamental understanding of the process–structure–performance relationships in these systems.
