UCI researchers have devised a new method of dynamically forming a platinum shell on a metallic alloy nanoparticle core, a development that may lead to better materials for oxygen reduction reactions in fuel cells that power some cars and electronic devices. In a first, engineers were able to observe the process directly, in real time, in UCI's state-of-the-art transmission electron microscopy facility, part of the recently established Irvine Materials Research Institute.
