Monolayer of aerosol-OT surfactants adsorbed at the air/water interface: An atomistic computer simulation study

Article Abstract:

The study carried out an atomistic molecular dynamics (MD) simulation to investigate the structural and dynamical properties of a monolayer of the anion surfactant bis(2-ethyl-1-hexyl) sulfosuccinate absorbed at the air/water interface. It concluded that the surfactant monolayer has a strong influence in restricting both the translational and reorientational motions of the water molecules close to the interface.

The electronic structure and orientation of styrene adsorbed on FeO(111) and Fe3o4(111)-a spectroscopic investigation

Article Abstract:

The adsorption of styrene on (111)-oriented thin layers of FeO and Fe3O4 epitaxially grown on Pt(111) single-crystal surfaces are investigated using near-edge X-ray absorption fine structure spectroscopy and X-ray photoelectron spectroscopy. The spectroscopic study of the adsorption of styrene on iron oxide surfaces reveals significant differences between the different oxides in their chemical behavior.

Solvent-induced organization of squaraine dyes in solution capillary layers and adsorbed films

Article Abstract:

Unusual behavior of indolenine and hydroxyphenyl squaraines is observed in solution capillary layers and adsorbed films. It is found that indolenine squarine is capable of forming H-aggregates in confined dimethylformamide solutions and hydroxyphenyl squarine is capable of forming J-aggregates in confined dimethylformamide solutions and adsorbed films.
