Rare earth metals/ oxides in nanoscale are widely studied for their use in catalysis, energy, environmental, and biomedical applications. Recently, nanoceria, a redox active material in the rare earth family, is being used as a high-temperature coating and as additives for chemical mechanical planarization (CMP) slurries in microelectronics. The morphologies of nanoceria play an important role in determining their redox and catalytic performances. Our research involves examination of the synthesis design strategies of CMP with various shapes and sizes and their effect on surface chemistry. While high-resolution TEM (HRTEM) is used to follow the particle structure-morphology evolution, the defected surfaces are studied using high resolution x-ray photoelectron spectroscopy (XPS). Atomistic computer simulations were used to help rationalize how the synthetic design impacts particle chemistry. Recently, we also discovered the unique antioxidant properties of the same rare earth ceria nanoparticles, where it protects mammalian cells against damage caused by increased reactive oxygen or nitrogen species and has been shown to act as an effective superoxide dismutase mimetic in vitro. This lecture will provide an overview of the biomedical applications of these redox active nanostructures. 2021 ASM/TMS Distinguished Lectureship in Materials and Society Tuesday, September 14 | 11:00 a.m. – 12:00 p.m. Prof. Ian M. Robertson, FASM University of Wisconsin-Madison “Hydrogen as an Energy Carrier” To meet the goals of increasing the amount of energy generated from renewable sources and decreasing CO2 emissions, several challenges must be overcome. First, the disparity in prime locations for renewable energy production and high-use regions such as large cities or industrial sites needs to be addressed. Second, there is a need for efficient energy storage systems to mitigate the difference in peak energy production periods to peak demand times. One option for a large-scale storage system is to use the produced energy to generate hydrogen fromwater and to deploy hydrogen gas as the energy carrier. Hydrogen can then be used to fuel the transportation sector, and to provide energy for buildings and various industries. This talk will look at the potential benefits of using hydrogen gas as an energy carrier and will identify the challenges associated with producing sufficient quantities of hydrogen to meet the needs and delivering it safely to the consumer. 2021 Edward DeMille Campbell Memorial Lecture Tuesday, September 14 | 9:40 – 10:40 a.m. Prof. Elizabeth A. Holm, FASM Carnegie Mellon University, Pittsburgh “Computational Materials Science: Past, Present, Future” Materials science and engineering calculations were among the first applications of digital computing, and the field of computational materials science has grown in proportion to computational power—which is to say, exponentially. We shall review the history of computing in support of materials research and observe how increases in computer capacity enable scientific advances with examples drawn from multiscale modeling in support of microstructural science. The transformative impact of integrated computational materials engineering and the Materials Genome Initiative will be discussed, along with the current focus on artificial intelligence, machine learning, and data science. Finally, we will make some predictions about where computational materials science will and will not take us in the next decade. Seal Robertson Holm 2021 LECTURERS ANNOUNCED
