Figure 3.

(a) A plot of the observed oscillation frequency in a jet as a function of the applied shaking frequency. The observed oscillation frequency is measured by dividing the number of pulses observed inside the device by the elapsed time between fast camera frames. The applied shaking frequency is indicated by the orbital shaker. (b) Optical microscope image of monodisperse water-in-water (w/w) emulsion droplets of 17 wt. % PEG solution in 16 wt. % dextran solution. Inset: optical microscope image of photo-crosslinked PEG-DA particles generated using an ATPS.
