Where did those electrons go? X-ray measurements solve decades-old mystery


November 2, 2017

There's been an unsolved mystery associated with mixed valence compounds: When the valence state of an element in these compounds changes with increased temperature, the number of electrons associated with that element decreases, as well. But just where do those electrons go? Using a combination of state-of-the-art tools, including X-ray measurements at the Cornell High Energy Synchrotron Source, Cornell University researchers have come up with the answer. Full Story
