Structure of the interface between two polar liquids: Nitrobenzene and water

Article Abstract:

Synchrotron X-ray reflectivity is used to explore the electron density as a function of depth through the bulk nitrobenzene-water interface at four different temperatures. The measured interfacial width differs from the predictions of capillary wave theory with a progressively smaller deviation as the temperature is raised and computer simulations have suggested a presence of both molecular layering and dipole ordering parallel to the interface.

Photoemission studies of polythiophene and polyphenyl films produced via surfaces polymerization by ion-assisted deposition

Article Abstract:

A study is carried out on the conducting polymer films that are grown by mass-selected, hyperthermal thiophene ions coincident on a surface with a thermal beam of organic monomers of either alpha-terthiophene (3T) or p-terphenyl (3P) neutrals. The conducting polymer films formed by surface polymerization by ion-assisted deposition (SPIAD) displayed new valence band features.

Nanostructure of fluorocarbon films deposited on polystyrene from hyperthermal C3F5(super +) ions

Article Abstract:

The complete structural analysis of the fluorocarbon films by comparing the X-ray reflectivity data with the power spectral densities of the atomic force microscopy (AFM) data is presented. The deposition of the polyatomic fluorocarbon ions is explained with molecular dynamics simulations.
