Workshop 8: Advancing Actinide Science

Organizer: Lynda Soderholm

Actinide science continues to benefit enormously from synchrotron-based techniques. This workshop will highlight recent experiments that offer new insights into long-standing problems. In addition, examples of recent work will be presented that reveal new directions and opportunities for studying structures and speciation in complex systems. Although these examples will pertain to problems in actinide research, their relevance to more mainstream applications will also be addressed.
