Biography

Dr. William J. Weber is currently the Governor’s Chair Professor for Radiation Effects on Materials in the Department of Materials Science and Engineering at the University of Tennessee, with a joint appointment at Oak Ridge National Laboratory. He also serves as Director of the Ion Beam Materials Laboratory. He received his BS (1971) in Physics from the University of Wisconsin, Oshkosh, and his MS (1972) and PhD (1977) in Nuclear Engineering from the University of Wisconsin, Madison. In 1977, he joined the staff of Pacific Northwest National Laboratory (PNNL) and was appointed Laboratory Fellow in 1997. In 2010, he joined the faculty at the University of Tennessee. Dr. Weber is internationally recognized for his work on radiation effects and ion beam modification of ceramics. Much of his current research is focused on the effects of energy dissipation processes on the production and evolution of defects and nanostructures in ceramics, as well as on the long-term performance of nuclear ceramics. He is a Member of the EU Academy of Sciences and a Fellow of the American Ceramic Society, the American Association for the Advancement of Science, the Materials Research Society, the American Physical Society and Ion Beam Society of India. He is a recipient of the Lee Hsun Lecture Award (IMR, Chinese Academy of Sciences), Outstanding Young Alumni Award and Distinguished Alumni Award (University of Wisconsin-Oshkosh), the PNNL Laboratory Director’s Award for Individual Lifetime Achievement in Science & Technology; and the PNNL Chester L. Cooper Mentor of the Year Award. He has chaired over 30 international conferences, society symposia, and topical workshops, and he currently serves as a principal editor for the Journal of Materials Research.

Dr. Weber has published over 545 journal articles, 113 peer-reviewed conference papers, 12 book chapters, and 54 technical reports. His work has been widely cited, with more than 23,700 citations and an h-index of 73. He has delivered over 220 invited presentations at scientific conferences, workshops, research institutions and universities.

"Swift heavy ion track formation in Gd2Zr2-xTixO7 pyrochlore: Effect of electronic energy loss" Maik Lang, Marcel Toulemonde, Jiaming Zhang, Fuxiang Zhang, Cameron Tracy, Jie Lian, Zhongwu Wang, William Weber, Daniel Severin, Markus Bender, Christina Trautmann, Rodney Ewing, Nuclear Instruments and Methods in Physics Research, Section B: Beam Interactions with Materials and Atoms Vol. 336 2014 102-115 Link
The morphology of swift heavy ion tracks in the Gd2Zr2-xTixO7 pyrochlore system has been investigated as a function of the variation in chemical composition and electronic energy loss, dE/dx, over a range of energetic ions: 58Ni, 101Ru, 129Xe, 181Ta, 197Au, 208Pb, and 238U of 11.1 MeV/u specific energy. Bright-field transmission electron microscopy, synchrotron X-ray diffraction, and Raman spectroscopy reveal an increasing degree of amorphization with increasing Ti-content and dE/dx. The size and morphology of individual ion tracks in Gd2Ti2O7 were characterized by high-resolution transmission electron microscopy revealing a core–shell structure with an outer defect-fluorite dominated shell at low dE/dx to predominantly amorphous tracks at high dE/dx. Inelastic thermal-spike calculations have been used together with atomic-scale characterization of ion tracks in Gd2Ti2O7 by high resolution transmission electron microscopy to deduce critical energy densities for the complex core–shell morphologies induced by ions of different dE/dx.
