Our understanding of the dielectric response of interfacial water, which underlies the solvation properties and reaction rates at aqueous interfaces, relies on the linear response approximation: an external electric field induces a linearly proportional polarization. This implies antisymmetry with respect to the sign of the field. Atomistic simulations have suggested, however, that the polarization of interfacial water may deviate considerably from the linear response. Here we present an… Expand

TLDR
This study applied an external gate potential to the silica/water interface via an electrolyte-insulator-semiconductor (EIS) junction to control the surface charging state, and found a drastic enhancement of interfacial OH vibrational signals at high potential in weakly acidic water. Expand

Water Structure, Dynamics and Sum-frequency Generation Spectra at Electrified Graphene Interfaces.
TLDR
It is shown that the value of the applied electrode potential has dramatic effects on the structure and dynamics of interfacial water molecules, and electrified graphene interfaces provide promising paradigm systems for comprehending both short- and long-range neighboring aqueous system impacts.

TLDR
Experimental evidence is provided that not only screening of surface charges but also interference limits the extent to which V-SFG probes interfacial water at sub-mM salt concentrations. Expand

TLDR
This work determines the response of the tangential component of the surface tension to the application of an electric field normal to the surface using finite field molecular dynamics simulations and finds an upside down parabola with a maximum shifted away from zero field. Expand
Unified molecular view of the air/water interface based on experimental and theoretical χ(2) spectra of an isotopically diluted water surface.
TLDR
The present study indicates that there is no ice-like structure at the surface, but that there are water pairs interacting with a strong hydrogen bond at the outermost surface, and confirms that the major source of the isotope effect on the water χ((2)) spectra is the intramolecular anharmonic coupling, i.e., Fermi resonance.

In situ probing electrified interfacial water structures at atomically flat surfaces
TLDR
To elucidate the structures of electric double layers at electrochemical interfaces, in situ Raman spectroscopy and ab initio molecular dynamics are combined and two structural transitions of interfacial water at electrified Au single-crystal electrode surfaces are identified. Expand
Effect of field direction on electrowetting in a nanopore.
TLDR
Reduction of surface free energy observed upon alignment of confinement walls with field direction suggests a novel mechanism whereby the applied electric field can operate selectively on water-filled nanotubes while empty ones remain unaffected. Expand

SERS is used to measure the vibrational Stark shifts of surface-bound thiolated-benzonitrile molecules bound to an electrode surface during hydrogen evolution reactions (HERs), which results in a highly linear electric field versus applied electrochemical voltage relation. Expand
