  • Although it is well known that silica can dissolve in water, the precise mechanism is unclear. Here, the authors employ sum frequency generation spectroscopy to probe the interfacial water structure reporting directly on the underlying dissolution mechanism, which appears to be auto-catalytic.

  • The surface chemistry of aqueous solutions plays a ubiquitous role in many chemical and biological processes. Here, the authors probe the surfaces of sodium halide solutions with surface-specific femtosecond vibrational spectroscopy, and observe surface concentrations of halide ions several times greater than in the bulk.

  • Reactions at the interface between mineral surfaces and flowing liquids are ubiquitous in nature. Here the authors explore, using surface-specific sum frequency generation spectroscopy and numeric calculations, how the liquid flow affects the charging and dissolution rates leading to flow-dependent charge gradients along the surface.

  • What do a rock in a river, a red blood cell in our body and the electrodes inside a car battery have in common? Charged surfaces in contact with water. Although a unified approach to study such a variety of systems is not available yet, the current understanding — even with its limitations — paves the road to the development of new concepts and techniques.
