Actinides and Rare Earths exhibit unique and diverse physical, chemical, and magnetic properties resulting from the complexity of the 5f and 4f electronic structure. The Actinide and Rare Earth Focus Topic Session concentrates on the fundamental chemistry, physics, materials, and interface science of f-electron materials with an emphasis on all aspects of nuclear technology while facilitating the involvement of early career scientists. The role of fundamental f-electron science in resolving challenges posed by actinide chemistry and materials will be central, particularly with regard to topics such as separation science, nuclear fuels, structural materials, nuclear energy processes, nuclear safeguards/forensics, and stewardship. Contemporary experimental approaches, including synchrotron radiation-based investigations and emerging techniques, all coupled to theory, will be featured to understand these complex materials.
