Biography
Changyong Park is a Beamline Scientist at HPCAT, Sector 16 of Advanced Photon Source located at Argonne National Laboratory. He developed the Resonant Anomalous X-ray Reflectivity technique for probing element-specific ion-adsorption profiles at mineral and aqueous solution interfaces (Park and Fenter, 2007). Combined with the high spatial resolution feature in the High-Resolution X-ray Reflectivity, this technique allows probing both specifically and non-specifically bound ion species at mineral surfaces, thus identifying the sterically resolved adsorbed species, i.e., inner-sphere adsorbed species vs. outer-sphere species.
