The ability to obtain a molecular-level understanding of the chemistry that takes place at
liquid/solid interfaces is key to the development and improvement of many chemical and …

Although a molecular monolayer is only a few nanometers thick it can completely change
the properties of a surface. Molecular monolayers can be readily prepared using the …

Proton transfer across single-layer graphene proceeds with large computed energy barriers
and is therefore thought to be unfavourable at room temperature unless nanoscale holes or …

This review discusses recent advances in the nonlinear optics of environmental interfaces.
We discuss the quantitative aspects of the label-free approaches presented here and …

Applications of the interface-selective methods of second harmonic (SHG) and sum
frequency (SFG) spectroscopy to the investigation of equilibrium and time-dependent …

Understanding the acid− base behavior of silica surfaces is critical for many nanoscience
and bionano interface applications. Silanol groups (SiOH) on silica surfaces exhibit two …

We imaged the interfacial structure and dynamics of water in a microscopically confined
geometry, in three dimensions and on millisecond time scales, with a structurally illuminated …

Specific ion effects (SIEs) are known to influence the acid/base behavior of silica and the
interfacial structure of water, yet evidence of the effect of pH on SIEs is lacking. Here …

Ionic binding of alkali ions Na+ and K+ to the carboxylic acid headgroups of fatty acid
monolayers is studied as a proxy toward understanding the fundamental chemistry in cell …

Using nonresonant second harmonic generation spectroscopy, we have monitored the
change in surface charge density of the silica/water interface over a broad pH range in the …
