Figure 5. Spatial and temporal control of boiling.

Figure 5

A solution of 2.6 mM DTAB (positively charged) in DI water was pool boiled in an experimental set-up (a) where eight separate gold electrodes were switched between −2.0 V (yellow) and −0.1 V (grey) to turn on/off bubble nucleation. Images taken at different times with a high-speed camera show (b) no nucleation of bubbles when no electrodes were activated, and (cj) bubble nucleation only on the particular electrode that was activated. Times in each frame correspond to those in Supplementary Movie 2. Scale bar, 1 cm.
