The kinetics of the potassium thiocyanate transport mediated by dicyclohexyl-18-crown-6 (L) through a bulk liquid membrane is studied experimentally and theoretically. The proposed model is based on the assumption of a pure diffusion of the complex salt [K·L]+SCN¯ through the liquid membrane stagnant films at the interfaces. It illustrates the ...

Water contamination with harmful arsenic compounds represents one of the most serious calamities of the last two centuries. Natural occurrence of the toxic metal has been revealed recently for 21 countries worldwide; the risk of arsenic intoxication is particularly high in Bangladesh and India but recently also Europe is facing similar problem. Liquid membranes (LMs) look like a promising alter...

The oxygen carrying performance of a perfluorooctyl bromide (PFOB) emulsion is considered. The intended purpose is to enhance hepatocyte growth and function in a bio-artificial liver support system (BALSS). Such oxygen carrying emulsions have previously been used in biological systems (e.g. cell culturing). However, optimum emulsion characteristics for enhanced oxygen mass transfer have not bee...

Photo-responsive double emulsions made of liquid crystal (LC) were prepared by a microfluidic device, and the light-induced processes were studied. The phase transition was induced from the center of the topological defect for an emulsion made of (N-(4-methoxybenzylidene)4-butylaniline (MBBA), and strange texture change was observed for an emulsion made of 4-cyano-4′pentylbiphenyl (5CB) doped w...

The bijel is a new class of soft material comprised of two fluids arrested in a bicontinuous configuration on the mesoscale. We stabilize the fluid structure using an interfacial layer of silica particles. The particles become trapped at the liquid-liquid interface because they reduce the exposed area; this relies on the particles being partially wetted by both liquids. We use water and 2,6-lut...
