The molecular level structure of materials gives rise to their properties. However, it is challenging to determine the structure of materials that lack long-range order, making it difficult to form structure-property relationships. My research group develops and applies solid-state nuclear magnetic resonance (SSNMR) spectroscopy to obtain detailed structural models of materials. SSNMR spectroscopy is amongst the most powerful atomic level characterization technique for solids because it can measure inter-atomic distances, and probe chemical bonding and symmetry with element specificity in both ordered and amorphous systems. In this talk, I will illustrate how sensitivity-enhanced SSNMR spectroscopy techniques can be applied to study the structures of inorganic nanomaterials such as semiconductor nanoparticles, disordered 2D materials, and heterogeneous catalysts.
Aaron Rossini is an Associate Professor of Chemistry at Iowa State University and a Faculty Scientist at the US DOE Ames Laboratory. He has published more than 150 peer-reviewed publications. His independent research was recognized with a Alfred P. Sloan Research Fellowship in 2020 and he was awarded the Caldarelli Prize in Magnetic Resonance for Young Investigators at the 2019 Alpine Conference on Magnetic Resonance. He completed his PhD studies in September 2010 at the University of Windsor, Windsor, Ontario, Canada, under the supervision of Prof. Robert W. Schurko. In 2011 he moved to Lyon, France to work with Prof. Lyndon Emsley and Dr. Anne Lesage at the Centre de Resonance Magnetique Nucleaire à Très Haut Champs (CRMN Lyon) at the Ecole Normale Superieure de Lyon (ENS Lyon) as a Marie Curie International Incoming Fellow. In October 2014 he moved to École Polytechnique Fédérale de Lausanne (EPFL) in Lausanne, Switzerland to continue working with Prof. Emsley. In August 2015, he moved to Ames, Iowa to join the Department of Chemistry at Iowa State University as an Assistant Professor. He was promoted to Associate Professor in August 2021 and to Full Professor in August 2023.
