Specifics about Specific Ion Adsorption from Heterodyne-Detected Second Harmonic Generation
Mavis D. Boamah, Paul E. Ohno, Emilie Lozier +2
Ion specific outcomes at aqueous interfaces remain among the most enigmatic phenomena in interfacial chemistry. Here, charged fused silica/water interfaces have been probed by homo…

Beyond the Gouy-Chapman Model with Heterodyne-Detected Second Harmonic Generation
Paul E. Ohno, HanByul Chang, Austin P. Spencer +4
We report ionic strength-dependent phase shifts in second harmonic generation (SHG) signals from charged interfaces that verify a recent model in which dispersion between the funda…

Dendritic Oxide Growth in Zero-Valent Iron Nanofilms Revealed by Atom Probe Tomography
Mavis D. Boamah, Dieter Isheim, Franz M. Geiger
Atom probe tomography (APT) analysis of chemically pure nanofilms of zero-valent iron (Fe(0), or ZVI) and their thermal oxide nano-overlayers reveals the presence of dendritic iron…
