Description:: Many processes in nature and human-made settings rely on the unique properties of charged metal oxide:aqueous interfaces. Despite their ubiquity, these buried interfaces are challenging to study, since any analytical technique aiming to overcome the relatively small number density of interfacial versus bulk species must be highly sensitive and surface-selective....

Description:: The nonlinear optical technique, second harmonic generation (SHG), is applied here for the first time to probe single and double strand DNA (ssDNA and dsDNA) chemically attached to fused quartz/water interfaces. DNA interfaces are often a critical functional component of biodetection, thus, the development of molecular biosensors requires a thorough...

Description:: Interfaces and surfaces are ubiquitous in the environment. Heterogeneous binding events and reactions control the transport and speciation of dissolved pollutants in groundwater. Many heterogeneous processes occur at mineral oxide/water interfaces, and can be controlled either by the mineral oxide, or organic molecules bound to the surface. The prevalent natural...
