Mark Schlossman of the UIC physics department and colleagues Matthew Tirrell, Ka Yee C. Lee, Yu-Sheng Chen and Binhua Lin received a five-year grant for $14.1 million to develop new capabilities at the National Science Foundation’s (NSF’s) ChemMatCARS.
ChemMatCARS is a facility where scientists use brilliant X-rays to study matter at the atomic and molecular levels. Researchers at the facility investigate the development of new energy sources, new materials for a wide range of industries, new ways to care for the environment and new understanding of how life works.
The study of crystals of small molecules at NSF’s ChemMatCARS facility allows scientists to measure ordering at the atomic level and probe the shape of chemical bonds. New instrumentation supported by this grant will advance the study of structural changes that occur during irreversible chemical and physical reactions and processes, which have proven challenging to characterize on the atomic scale.
Research also reveals electron transfer in clusters of bound atoms and molecules, giving scientists an atomic-level understanding of what drives chemical reactions and allowing them to design new compounds with atomic-level precision. The new instrumentation will support studies that replace precious metals with earth-abundant metals while preserving the efficiency and selectivity of catalytic chemical reactions.
The study of liquid interfaces at the facility reveals the way molecules and nanoparticles interact within molecularly thin layers at liquid-liquid and liquid-vapor boundaries. New initiatives supported by this grant will address the challenge of characterizing the heterogeneity of liquid surfaces and interfaces on the nanoscale. The study of liquid-solid interfaces will be advanced by new instrumentation, which has the potential to address a wide range of scientific problems in the areas of water purification, protein-membrane interactions to determine the rules of life, and electrolyte-electrode interactions for catalysis and energy applications.
Located at the Advanced Photon Source, Argonne National Laboratory, the NSF’s ChemMatCARS serves as a training ground for national and international researchers at all levels, including STEM-focused students and future scientists.
