Figure 19.

(a–e) Thermally induced splitting of a dodecane drop on a partially wetting stripe (w = 1,000 µm). The voltage applied to the microheater (155 Ω) was 2.5 V. The images were recorded at t = 0, 6.0, 7.5, 8.0, and 8.5 s. (f–i) Dodecane drop propelled through an intersection outlined by the dark gray pattern (w = 1,000 µm, time lapse 104 s). (j–l) Dodecane drop turning a 90° corner (time lapse 164 s). Reprinted with permission from [24]. Copyright 2003, American Institute of Physics.
