Sergei Kalinin and Mariappan Parans Paranthaman, researchers at the U.S. Department of Energy's Oak Ridge National Laboratory (ORNL), have been elected fellows of the Materials Research Society (MRS). The professional society, which limits fellows to 0.2 percent of the MRS membership, is dedicated to the worldwide advancement of materials research. Kalinin is director of ORNL's Institute for Functional Imaging of Materials and a distinguished staff member at the Center for Nanophase Materials Sciences, and is an adjunct associate professor of materials science and engineering at the University of Tennessee, Knoxville. He is cited for "pioneering contributions to the understanding of nanoscale ferroelectric, transport and electrochemical phenomena in complex oxides through the development of scanning probes techniques." At ORNL, Kalinin develops novel scanning probe microscopy (SPM) techniques to measure and control local structure and properties of materials. He joined ORNL in 2002 as a Eugene P. Wigner Fellow after earning bachelor's and master's degrees in chemistry and materials science from Moscow State University and a doctoral degree in materials science from the University of Pennsylvania. Paranthaman, a distinguished research staff member and leader of the Materials Chemistry group of ORNL's Chemical Sciences Division, was cited for "pioneering contributions to materials chemistry, including research, development, and commercialization of materials for superconductors, solar cells and energy storage, and for exceptional service to the materials community." He serves on the faculty for the University of Tennessee's Bredesen Center for Interdisciplinary Research and Graduate Education. Paranthaman is also a fellow of the American Association for the Advancement of Science, ASM International, the American Ceramic Society and the Institute of Physics in London. He received his doctorate in solid-state chemistry from the Indian Institute of Technology, Madras, in 1988. Kalinin and Paranthaman will be honored at the professional society's annual meeting in April. MRS is a nonprofit organization that brings together scientists, engineers and research managers from industry, government, academia and research laboratories to share findings in the research and development of new materials of technological importance.
