John F. Mitchell is an Argonne Distinguished Fellow and Interim Division Director of the Materials Science Division at Argonne National Laboratory. He received his A.B. from Cornell University in 1987 and his Ph.D. from the University of Chicago in 1993 for theoretical studies of defect structures and order-disorder transitions of early transition metal chalcogenides. His current research emphasizes strategic synthesis, crystal growth, and structural studies of correlated electron transition metal oxides and chalcogenides using neutron and X-ray scattering.
Paul Fenter received a B.S. in Physics at the Rensselaer Polytechnic Institute in 1984, and a PhD in Physics from the University of Pennsylvania in 1990. He then worked at Princeton University, first as a post-doctoral fellow and then as a research staff member. He joined the staff at Argonne National Laboratory in 1997 where he uses and develops a range of synchrotron X-ray scattering techniques (e.g., X-ray reflectivity, X-ray standing waves, resonant X-ray reflectivity, interfacial X-ray microscopy) to probe the structures and processes at solid-liquid interfaces through direct in-situ observations. His interests range from mineral-water interfaces in geochemical systems, electrical double-layer structure (e.g., in water, ionic liquids), as well as interfaces in electrical energy storage systems. He is a senior physicist and group leader for Interfacial Processes in the Chemical Sciences and Engineering Division. He has served, since 2014, as Director of the Center for Electrochemical Energy Science a DOE-funded Energy Frontier Research Center. He is a Fellow of the American Physical Society and the winner of the 2012 Bertram E. Warren Diffraction Physics Award from the American Crystallographic Association.
Multiscale correlations and hierarchies in solutions
David Tiede is a leading specialist in developing solar cell technology. At Argonne, Tiede is the Photosynthesis group leader, exploring the potential for harnessing photochemical energy in natural and artificial photosynthesis. In 2007, he co-founded the Argonne-Northwestern Solar Energy Research (ANSER) Center, a partnership with Northwestern University to explore the Sun’s potential to supply energy for human needs.
Tiede received his B.A. and Ph.D. from the University of Pennsylvania. After studying as a post-doctoral fellow in at the Centre CEA de Saclay, France, he came to Argonne in 1984 and has worked here ever since, serving as senior chemist and group leader for projects in the Chemistry Division.
