Entrainment Reduction in a Static-Mixer Settler Setup by Electric Field Enhanced Coalescence

Surfactant-enhanced liquid-liquid extraction in microfluidic channels with inline electric-field enhanced coalescence.

Continuous microfluidic liquid-liquid extraction is realized in a microfluidic device by generating emulsions with large interfacial areas for mass transfer, and subsequently breaking these emulsions using electric fields into easily separated segments of immiscible liquids (plugs). The microfluidic device employs insulated electrodes in a potassium hydroxide-etched channel to create large elec...

The Effects of a Surfactant Concentration on the Mass Transfer in a Mixer-Settler Extractor

The effects and influences of various parameters upon the efficiency and the overall volumetric mass transfer coefficients are important subjects to be studied in most liquid-liquid extraction processes. One of these important parameters is surface active agent (surfactant). In this paper, in order to study the effect of sodium dodecyl sulfate (SDS) concentration on the efficiency and the a...

Quasi-static electric-field-enhanced diffraction effects in a nematic liquid-crystal film.

A quasi-static electric field can enhance laser-induced diffraction rings from a nematic liquid-crystal film. This phenomenon is shown to be the combined result of the critical behavior of the sample at the Freedericksz transition and the nonlinear coupling of the optical and quasi-static electric fields.

Quasi-static electric-field-enhanced degenerate four-wave mixing in a nematic liquid-crystal film.

Degenerate four-wave mixing can be induced or enhanced dramatically when two weak overlapping laser beams are incident upon a nematic liquid-crystal film that is biased by a quasi-static electric field. This phenomenon is shown to be the result of the critical behavior at the Freedericksz transition. The experimental results show that the diffracted intensity is proportional to the third power ...
