Microemulsions: Thermodynamic and Dynamic Properties
Mixing two immiscible liquids (such as oil and water) using emulsifier and energy inputs has been the matter of study for decades. In early 1890’s extensive work have been carried out on macroemulsions (i.e. oil dispersed in water in the form of fine droplets or vice versa) (Becher, 1977) and several theories and methods of their formation have been vastly explored (Lissant 1976 and 1984). Howe...
متن کاملMolecular thermodynamic modeling of droplet-type microemulsions.
Microemulsions are nanoheterogeneous, thermodynamically stable, spontaneously forming mixtures of oil and water by means of surfactants, with or without cosurfactants. The pledge to use small volumes of amphiphile molecules compared to large amounts of bulk phase modifiers in a variety of chemical and industrial processes, from enhanced oil recovery to biotechnology, fosters continuous investig...
متن کاملBuilding Qualitative Models of Thermodynamic Processes
This paper describes a qualitative domain theory for core phenomena in engineering thermodynamics, expressed in Qualitative Process theory . It represents many of the best features of domain models developed by our group over the past five years . It focuses on supporting system-level qualitative analyses of typical fluid and thermal systems, such as refrigerators and power plants . We use expl...
متن کاملMicroemulsions – A Brief Introduction
Nevertheless, the existence and application history of the microemulsions goes back to the very older times, but the oldest available reports in this field have been published by Schulman (Schulman & Hoar, 1943) and Winsor (Winsor, 1954). Their works are the starting point of efforts for the systematic understanding of the microemulsions. Meanwhile, the widespread generalization and application...
متن کاملCrystallization of Mefenamic Acid from Dimethylformamide Microemulsions: Obtaining Thermodynamic Control through 3D Nanoconfinement
Recently we showed how crystallization in microemulsions could lead directly to the most stable polymorph, thereby leapfrogging Ostwald’s rule of stages. Here we consider in more details the crystallization of mefenamic acid from dimethylformamide microemulsions. Crystallization of mefenamic acid from bulk DMF has previously been shown to produce only the metastable Form II irrespective of the ...
