Actinide materials exhibit unique and diverse electronic, transport, and chemical properties, largely resulting from the complexity of their 5f electronic structure. This Symposium will focus on a range of topics in physics, chemistry, and materials science of actinides that are of contemporary interest. Emphasis will be on 5f electronic and magnetic characteristics; synthesis; surface science; radiation damage and Pu aging; bulk, thin-film, and nanoparticle properties; and applications of each to nuclear energy and security-related issues. The role of fundamental and targeted actinide science in resolving challenges in actinide materials processing and environmental and technical issues with actinide materials will be stressed, particularly regarding energy applications, including novel nuclear fuels and structural materials, waste remediation, and waste disposal. Experimental approaches, including state-of-the-art techniques and synchrotron radiation- and neutron-based investigations, as well as theoretical modeling, are parts of the Symposium. Actinide issues related to nuclear forensics, non-proliferation, security, and the renaissance in nuclear energy, including fuel synthesis, oxidation, corrosion, actinide stability in extreme environments and biological media, prediction of properties via simulations, separation science, and environmental impact are all critical to the future of actinide science that will be discussed herein. The previous eleven Actinide Symposia were held in Boston, San Francisco, Phoenix, Seattle, and most recently in Honolulu (Spring 2022).
