A new micropipet technique has been developed to measure the equilibrium and dynamic interfacial tensions of microscopic liquid−gas and liquid−liquid interfaces. In this technique, a liquid−gas or liquid−liquid interface with a radius of curvature ranging from 1 to 100 μm can be created inside a tapered micropipet. On the basis of the Laplace equation (a work balance between tension and applied pressure for the curved interface), the equilibrium interfacial tension between the two phases (clean… CONTINUE READING
