Ionic liquids (ILs) are largely made of ions and short-lived ion pairs. These often possess a unique combination of physical and chemical properties which are not available with molecular solvents. ILs are dynamic, attractive and rich research area and are gaining considerable attention as promising molten materials for a variety of applications in pharmaceutical and biotechnology fields. Ionic...

The MHD oscillatory flow of two immiscible, viscous liquids in a porous channel with heat transfer is the subject this investigation. liquid layers different viscosities both regions. analytical expressions for velocity and temperature distribution have been derived by solving governing equations using regular perturbation method. effects various parameters on velocity, temperature, Nusselt num...

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 co-surfactant. Nanoemulsion sizes fall typically range 20-200 nm shows narrow distribution. They enhanced functional properties comparison conventional emulsions. The compo...

Two-fluid Dean vortex flow in a coiled pipe with vanishing torsion, and its effect on the mass transfer through the liquid–liquid interface of two immiscible fluids are studied numerically. The liquids are stratified by gravity, with the denser one occupying the lower part of the pipe. The Navier–Stokes equations in both fluid layers are solved numerically by the finite volume method. The resul...

We have devised a method of making a flat oil/water interface which remains flat on inversion. Cell adhesion to the interface can be observed microscopically. Glutaraldehyde-fixed human red blood cells adhere to the interface between physiological saline and hexadecane containing surface-active behenic acid at pH values below about 7-5. At high pH values, cells are prevented from adhering due t...

A mathematical analogy between paraxial optics with two circular polarizations of light in a defocusing Kerr medium positive dispersion, binary Bose-Einstein condensates cold atoms the phase separation regime, and hydrodynamics immiscible compressible liquids can help theoretical search for unknown three-dimensional coherent optical structures. In this work, transversely trapped (by smooth prof...

We have detected unique hydrodynamic topology in thin air film surrounding the central dimple formed during drop impact on an immiscible liquid pool. The pattern resembles spinodal and finger-like structures typically found various condensed matter systems. However, similar entrapped gas films impacts solids or liquids not been reported to date. thickness profile associated dewetting dynamics l...

A series of experiments were conducted to investigate the melting ice adjacent a water-immiscible liquid layer (n-dodecane) exposed radiation from above. The experimental setup consisted borosilicate container containing an wall and n-dodecane heated In addition tracking movement melt front, Particle Image Velocimetry (PIV) Background Oriented Schlieren (BOS) measurements on liquid-phase.
