Contact angle goniometers ( q . v . ) can also determine the surface tension for any liquid in gas or the interfacial tension between any two liquids.
22.
"' Surfactants "'are compounds that lower the surface tension ( or interfacial tension ) between two liquids or between a liquid and a solid.
23.
In these systems, lactylates are added to decrease the interfacial tension between the mutually insoluble components providing stability to the mixture, referred to as a colloidal suspension.
24.
Analysis of a pre-nucleation induction period yielded a supercluster interfacial tensions that compare reasonably well with other theory and Christopher Sorensen's research group's experiments.
25.
Since the equilibrium shape of a droplet tends towards the one with the minimum energy, a large value of interfacial tension tends to drive the droplet shape towards a sphere.
26.
The interfacial tensions can be measured using common experimental techniques such as a Wilhelmy plate or the Du No�y ring method to predict if the adhesive will make good contact with the membrane.
27.
The size of the generated droplets is mainly controlled by the flow rates of the continuous phase and dispersed phase, interfacial tension between two phases and the geometry used for the droplet generation.
28.
Such fluids ( sometimes known as coacervates ) have very low interfacial tension with water so they are very useful as encapsulants and also as agents to drive self-assembly in aqueous systems.
29.
Both surfaces have to be created ( which requires a huge amount of energy ), and the interfacial tension ( difference of surface tension ) is not compensating the energy input, if at all.
30.
Where " ?" is the dynamic viscosity of the liquid, " V " is a characteristic velocity and \ sigma is the surface tension or interfacial tension between the two fluid phases.
