The rapid evaporation of a superheated liquid (vapor explosion) under microgravity conditions is studied by direct numerical simulation. The time-dependent Navier-Stokes and energy equations coupled to the interface dynamics are solved using a two-dimensional nite-di erence/front-tracking method. Large interface deformations, topology change, latent heat, surface tension and unequal material pr...

Liquid–liquid interfaces and nucleation in partially miscible Lennard–Jones ~LJ! mixtures are considered using density functional theory. We present phase diagrams, interfacial liquid–vapor and liquid–liquid profiles, and gas–liquid as well as liquid–liquid surface tensions for two types of mixtures having different mixing rules for the LJ energy parameter. A simple local density approximation ...

In this paper I describe total reflection of great brilliancy that seems to indicate that an interface can be very thin.

Our studies of thermally excited surface waves on liquids by means of light scattering, as described in earlier reports,l'2 have been extended to the problem of surface waves on the interface between two liquids. As a specific example, we have considered the methanol-hexane interface. A laser beam is scattered off the interface, and the light scattered in a certain direction is analyzed by mean...

The development of the Abbott Liquid-Liquid Extraction Station was a result of the need for an automated system to perform aqueous extraction on large sets of newly synthesized organic compounds used for drug discovery. The system utilizes a cylindrical laboratory robot to shuttle sample vials between two loading racks, two identical extraction stations, and a centrifuge. Extraction is performe...

A novel rectangular channel flow electrochemical cell for the study of liquid liquid interfaces is presented. The organic phase is immobilised by the use of a gelling agent, while the aqueous phase flows past the interface. This creates an asymmetric setup that allows us to establish diagnostic criteria to determine, for example, the direction of the ion transfer. The effects of varying flow ra...
