X-ray imaging setup and air bubble entrapment by drop impact on a liquid pool. (a) Schematic of X-ray imaging coupled with drop-impact setup. (b) Schematic of the bubble entrainment. When a liquid drop falls onto a liquid pool, a thin air film is entrapped and eventually contracts to one bubble or a few bubbles by surface energy minimization. (c) X-ray images corresponding to sketches in (b). The scale bar is 100 μm long.
