This research project is concerned with the drainage and stability of           thin films which could be associated with unstable foams.  The role of          surface viscosity in coalescence at liquid-gas interfaces is                    investigated using single bubbles.  The premise of previous work is             that the same factors influence both the coalescence of single bubbles          or drops at phase interfaces and the displacement of an unstable foam           in a porous medium.  This research project focuses on studying, both            theoretically and experimentally, the problem of the coalescence of             single bubbles or drops.  A more detailed theory that will include the          effects of any electrostatic double-layer forces is currently being             developed.  Using these theories as a basis, a systematic experimental          study of the effects of the surface viscosities upon the coalescence            times of single bubbles at liquid-gas interfaces is initiated.  This            includes complementary measurements of the two surface viscosities.
