an unclad optical fibre is immersed in the liquids and its optical attentuation is measured; the fibre has a refractive index greater than that of the second liquid, but not more than 01 greater than the first,

Analytes of interest may also be extracted from a source sample by liquid-liquid extraction (LLE). LLE is used to separate analytes based on their relative solubilities in two immiscible or partially miscible liquids, usually a polar solvent like water and a non-polar organic solvent. The target...
(2010) to perform visualization experiments showing the invasion drainage of porous media with density-matched immiscible liquids. The second liquid phase in these tests, an organic phase consisting of a mixture of soybean oil and carbon tetrachloride, was intentionally unmatched in RI, so that it ...
Aqueous two-phase systems (ATPS) based on ionic liquids (IL) and deep eutectic solvents (DES) are ecofriendly choices and can be used to selectively separate compounds of interest, such as bioactive compounds. Bioactive compounds are nutrients and nonnutrients of animal, plant, and microbial ori...
(acid) is in the range of 1000-100,000 Da. The second polymer is selected to be capable of forming immiscible aqueous phases in the presence of the poly(acid) and salt. The poly(acid) may be selected from the group consisting of poly(acrylic acid) and poly(methacrylic acid), and the...
A proof of concept device is fabricated to demonstrate this design. The hexagonal cell is dosed with two immiscible liquids. The liquid-liquid interface is modulated by varying the voltage to different electrode faces in the cell. By deforming the liquid shape in an electrowetting cell, light ...
However, the use of immiscible liquids causes optical disturbances due to a difference in refractive indices of the two liquids and due to a curved interface geometry. Particle images are thus imaged in a distorted field of view. The results of a PIV analysis will be inaccurate in scaling as...
Electrochemistry at the interface between two immiscible electrolyte solutions (IUPAC Technical Report)Abstract:This document provides an inventory of theoretical and methodologicalconcepts in electrochemistry at the interface between two immiscible electrolytesolutions (ITIES). Definitions of basic relationships ar...
Tracer particles (D: 0.5 - 1.2渭m) are added to either phase, enabling simultaneous measurements in both phases.rnHowever, the use of immiscible liquids causes optical disturbances due to a difference in refractive indices of the two liquids and due to a curved interface geometry. Particle ...
