New Strategies for Energy and Materials Research with NMR
NMR spectroscopy is a powerful tool for the study of structure and dynamics in complex materials systems. Atomic-, molecular-, and systems-level insights have been gained for environmental oxide interfaces, nuclear waste glasses, and various parts of battery systems (anodes, cathodes, and electrolytes) through recent, novel applications of NMR. These results are often analyzed in concert with computational chemistry to understand the complex behaviors of these systems while under environmental or operational conditions. In situ studies have also progressed in a number of areas, and multi-modal strategies are currently under consideration or development for simultaneous observations of NMR signals with other spectroscopic or technological signatures (such as chromatography). An overview of current experiments, strategies, and results will be presented along with a brief prospectus of future advancements and tools.
Short Biographical Sketch
Educated at the University of Rochester (B.S., Chemistry, 1985), Cambridge University (Churchill Scholar, Natural Sciences/Chemistry, 1986), and the University of California at Berkeley (Ph.D., Chemistry, 1991), Karl Mueller has been a faculty member at Penn State University for over twenty years. In 2010 he was recruited as a Laboratory Fellow to PNNL, where he leads a research team in the development and application of solid-state NMR to address complex problems including structure and dynamics in battery materials and catalyst systems. Remaining on the faculty at Penn State, he also directs a team of graduate students in studies of ionic conduction in polymer electrolytes and surface reactivity in the environment. Dr. Mueller is the author of over one hundred research communications, articles, and book chapters, and he was recently inducted as a Fellow of the American Association for the Advancement of Science.
