Observation of the mechanism of bubble nucleation in supersaturated emulsions: (a) Schematic presentation of the observation. (b) Nucleation observation in emulsion drops -UT at 7000 rpm, SI Movie S3. (c) Bubbles nucleation in the continuous phase - UT at 14,000 rpm, SI Movie S4. Optical observations in transmitted light at ×5 optical magnification. Image sequences represent ≈ 100 ms period. Images are 1680 μm wide.
