An emulsion is a mixture of two or more liquids that are normally immiscible ... The required surfactant concentration in a microemulsion is, however, several times ...
This requires a balance between fluid input and output, which is a balance between irrigation, aspiration and leakage. Repeated partial collapses of the anterior chamber, and iris fluttering during removal of the nucleus are signs of inadequate fluid supply, which can be adjusted by changing the height of the gravity feed supply bottle.
The ouzo effect during the preparation of absinthe. The ouzo effect (/ ˈ uː z oʊ / OO-zoh), also known as the louche effect (/ l uː ʃ / LOOSH) and spontaneous emulsification, is the phenomenon of formation of a milky oil-in-water emulsion when water is added to ouzo and other anise-flavored liqueurs and spirits, such as pastis, rakı, arak, sambuca and absinthe.
Micro-emulsion polymerization: Emulsion polymerization in which the starting system is a micro-emulsion and the final latex comprises colloidal particles of polymer dispersed in an aqueous medium. Note : Diameters of polymer particles formed in the micro-emulsion polymerization usually are between 10 and 50 nm.
Membrane emulsification (ME) is a relatively novel technique for producing all types of single and multiple emulsions for DDS (drug delivery systems), solid micro carriers for encapsulation of drug or nutrient, solder particles for surface-mount technology, mono dispersed polymer microspheres (for analytical column packing, enzyme carriers ...
In polymer chemistry, emulsion polymerization is a type of radical polymerization that usually starts with an emulsion incorporating water, monomers, and surfactants.The most common type of emulsion polymerization is an oil-in-water emulsion, in which droplets of monomer (the oil) are emulsified (with surfactants) in a continuous phase of water.
This type of emulsion is thermodynamically unstable, but can be stabilized for a period of time with applications of kinetic energy. [1] Surfactants (as the main emulsifiers ) are used to reduce the interfacial tension between the two phases, and induce macroemulsion stability for a useful amount of time.
Strictly speaking a wax emulsion should be called a wax dispersion since the wax is solid at room temperature. However, because the preparation takes place above the melting point of the wax, the actual process is called emulsification, hence the name wax emulsion. In praxis, wax dispersion is used for solvent based systems.
