Dynamic Liquid Film Interfaces

Axisymmetric drop shape analysis as penetration film balance applied at liquid–liquid interfaces

A new application of the axisymmetric drop shape analysis (ADSA) has been developed, using the pendant-drop film balance technology for penetration studies of insoluble monolayers at the liquid–liquid interface. A monolayer is spread on the surface of a drop of a buffer solution suspended from a capillary, which is the outer one of an arrangement of two coaxial capillaries connected to the two ...

Photocurrents at polarized liquid|liquid interfaces enhanced by a gold nanoparticle film.

Photocurrent responses associated with the interfacial quenching of the photo-excited water-soluble zinc meso-tetra(4-carboxyphenyl)porphyrin (ZnTPPC) by ferrocene have been studied at a water|1,2-dichloroethane interface in the absence and in the presence of adsorbed gold nanoparticles. Upon addition of methanol, a mirror-like gold film is formed and an important enhancement of the photocurren...

Liquid Film Dynamic on the Spray Impingement Modelling

The present paper addresses a liquid film sub-model included into a computational model that aims at reproducing the spray impingement phenomena. This numerical extension incorporates the spread of the liquid film over the neighbouring nodes due to the dynamic motion induced by the film inertia but also the exchange of mass between the liquid layer and the incident and splashing particles. More...

Dynamic labyrinthine pattern in an active liquid film.

We report the generation of a dynamic labyrinthine pattern in an active alcohol film. A dynamic labyrinthine pattern is formed along the contact line of air/pentanol/aqueous three phases. The contact line shows a clear time-dependent change with regard to both perimeter and area of a domain. An autocorrelation analysis of time development of the dynamics of the perimeter and area revealed a str...
