Dissolution of a 30 μm diameter air bubble into water. (A) A series of video images of the dissolution of an air microbubble in 10 mM SDS solution held in the center of the chamber by a pipet with a very low suction pressure of 500 Pa and 21.5 °C. The air bubble is shown at times 0 s (top left), 10 s (top right), 30 s (bottom left), and 48 s (bottom right) respectively, completely dissolving in ~50 s. (B) Plot of microparticle radius versus time for dissolution in isotropic and boundary-limited conditions where the data are fitted by the Epstein–Plesset (EP) model and an empirical model by Wise et al. [166].
