It is named after the mythological Titan who provided fire to human beings and whose name represents human striving.Groundbreaking Research at ORNL”The whole idea was to explore this extremely rare aspect to acquire brand-new understanding,” stated Alex Ivanov, an ORNL scientist who co-led the research. Utilizing a research study reactor, hot cells and supercomputers, as well as the built up understanding and skills of 18 researchers in different fields, the authors detailed the very first observation of a promethium complex in solution.The ORNL scientists bound, or chelated, radioactive promethium with unique natural particles called diglycolamide ligands.”Reference: “Observation of a promethium complex in service” by Darren M.
