Water at Interface with Proteins

Electro-Coalescence of an Aqueous Droplet at an Oil–Water Interface with an Investigation of Secondary Droplets Formation

Organic ions at the air/water interface

Direct spectroscopic evidence of the presence of organic phenolate ions at the air/aqueous interface has been established using the nonlinear spectroscopic technique of vibrational sum frequency generation (SFG). By probing the phenol C–OH and the phenolate C–O vibrational stretches, which occur in the range of 1200–1300 cm and are distinguishable, we have succeeded in determining the identitie...

Hydrated electrons at the water/air interface.

The dynamics of hydrated electrons at the water/air interface are investigated using time-resolved second-harmonic generation spectroscopy. Initial solvation occurs in approximately 1 ps, and the electron remains at the interface for >750 ps. The location of the electron relative to the dividing surface is investigated using surfactants, which show that the electron is hydrated in the interfaci...

Connectivity at the Land-Water Interface

Bacterial Accumulation at the Air-Water Interface

Accumulation at the air-water interface of four bacterial strains with different hydrophobicities was studied. To exclude system influences, both a static batch system and a dynamic system involving rising bubbles were used. All bacteria accumulated at the air-water interface in both systems. Generally, attachment to the air-water interface increased with bacterial surface hydrophobicity. Accum...
