  "abstract": "Surface bubbles are generally assumed to play only a passive role in evaporation. Here we show that they enhance the evaporation of volatile liquids by spontaneously generating a self-sustained thermocapillary circulation. Particle tracking and Schlieren imaging reveal converging flows in both phases towards the bubble apex, where a vapor fountain emerges. These flows arise from evaporative cooling, which generates temperature gradients along the bubble cap and therefore, thermocapillary stresses. A positive feedback loop ensues in which the bubble creates the conditions for the establishment of thermocapillary stresses, helps sustain itself and enhances evaporation. Boundary-layer analysis predicts that the additional evaporative flux generated by a bubble depends only on its size, in quantitative agreement with experiments. Our results identify surface bubbles on volatile liquids as simple self-sustained dissipative structures that involve and affect heat, mass and momentum transport at an interface.",
