Ion transfer across the interface of two immiscible liquids involves a mechanism for initiating desolvation from the first liquid, A, and concerted solvation by the second, B. In the present article a mechanism is considered in which this initiation is facilitated by the ion attaching itself to the tip of a solvent protrusion of B into A. ~Protrusions have been observed in computer simulations ...

The activity of lysozyme over a Micrococcus lysodeikticus cell suspension increased to 13% of the initial value in the presence of 1% v/v ammonium-based ionic liquids after deactivation with 4.0 M urea. This increase in activity reflects the refolding ability of the ionic liquids against the denaturation effects of urea on lysozyme.

When an ion moves across the interface of two immiscible electrolytes it moves together with the ion-induced protrusion of one solvent into the other. For an infinitely slow motion of an ion the height of the protrusion, heq , is a function of the position of the ion z. Due to a finite relaxation time the protrusion may not be able to spontaneously follow the motion of the ion, and this will ca...

A series of benchmarks based on the physical situation “phase inversion” between two immiscible liquids is presented. These aim at progressing towards direct numerical simulation two-phase flows. Several CFD codes developed in French laboratories and using either Volume-of-Fluid or Level-Set interface tracking methods are used to provide solutions benchmarks, convergence studies code comparison...

Nanoemulsions have small droplet size and are kinetically stable colloidal systems. These the thermodynamically isotropic system in which two immiscible liquids mixed to form a single phase by means of appropriate surfactant cosurfactant. Nanoemulsion sizes fall typically range 20–200 nm shows narrow distribution. They enhanced functional properties comparison conventional emulsions. The compos...

We present a two-layer thin film model allowing us to study the behavior of a general class of ‘wettability ratchets’ that can be employed to transport a continuous phase. Brownian ratchets, in contrast, are normally used to transport particles or molecules within a continuous carrier fluid without transporting the fluid itself. The wettability ratchet is based on a switchable, spatially asymme...
