An increase in the fluorescence lifetime of rhodamine B dye, when in contact with hematite nanoparticles in methanol from mildly acidic to alkaline pH, is consistent with the transfer of electrons from excited dye to the hematite conduction band.

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 fundamental and second harmonic beams modulates observed signal intensities

Atom probe tomography (APT) analysis of chemically pure nanofilms of zerovalent iron (Fe(0), or ZVI) and their thermal oxide nano-overlayers reveals the presence of dendritic iron oxide features that extend from the oxide nano-overlayer surface into

Current approaches for electric power generation from nanoscale conducting or semi-conducting layers in contact with moving aqueous droplets are promising as they show efficiencies of around 30 percent, yet, even the most successful ones pose challen

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 homodyne- and heterodyne-detected (HD) second harmonic generation (SHG) sp

We have investigated the dynamics of low-energy (1–20 eV) electron-induced reactions in condensed thin films of methanol (CH3OH) through both electron-stimulated desorption (ESD) and postirradiation temperature-programmed desorption (TPD) experimen
