  • Argonne researchers and their collaborators sought to understand what happens when an electron is injected into water. They found that the electron binds with the water; however, its binding energy is much smaller than previously thought. (Image courtesy of Peter Allen/Institute for Molecular Engineering.)

    Scientists have been able to experimentally measure the electron affinity of water, determining what happens to an electron when it is injected into water. The result has importance for photochemical cells and may force scientists to a reexamine certain theories about electronic binding energy.
