Fission, Collapse, and Re-emergence

This molecular argument may explain the earlier-described and repeatedly observed finding with concentrated gas-in-liquid emulsions (see Section 10.4) that, following a period of microbubble growth, the average hydrodynamic diameters (detected by photon correlation spectroscopy) of the microbubble and micellar populations simultaneously decreased. In such situations, microbubble fission may have occurred (following microbubble collision) and the surfactant molecules needed for the expanding
