Hydroxide adsorption on Ag(110) electrodes: An in situ second harmonic generation and ex situ electron diffraction study

Article Abstract:

The adsorption of hydroxide on the Ag(110) surface is studied with cyclic voltammetry, in situ second harmonic generation (SHG), and ex situ low energy electron diffraction (LEED) and reflection high energy electron diffraction (RHEED). OH(super -) is found to be adsorbed on the Ag(110) surface at potentials negative of the potential of zero charge, forming small antiphase domains of c(2x6) symmetry.

Surface tension of surfactant solutions

Article Abstract:

A study is describing how a so far unknown phenomenon, that of drastically decreasing the surface tension of surfactant solutions by lowering the solution's level in nonwetting containers can be achieved, is presented. The surfactant adsorption at the solid/solution interface can be estimated from the accompanying changes of the solution's surface tension.

Bending rigidity of interfaces in aqueous phase-separated biopolymer mixtures

Article Abstract:

A new model for interfacial tension and bending rigidity for liquid-liquid interfaces between semidilute polymer phases is presented. The equations for the interfacial properties for a two-phase multicomponent system are used for this purpose.
