[Abstract]

Droplets impacting on solid surfaces often trap air bubbles or splash. These phenomena originate from thinning of the air films trapped between the droplets and the solid surfaces. In this seminar, I will show how the entrapped air films can be manipulated using spatially periodic dielectrophoretic force. This approach offers a unique advantage in driving air flows in thin gaps, thereby work efficiently in suppression of both bubble entrapment and splashing.
