Spring 2013
For drops sessile on a solid surface, cross flowing air can drive drop oscillation or shedding, based on the balance and interaction of aerodynamic drag force (based on drop size/shape and air speed) and adhesion/capillary forces (based on surface tension and drop size/shape). Better...

Understanding the Role of Surface Microgeometries on Wetting: Designing Robust Superhydrophobic Surfaces
DownloadSpring 2014
This thesis is concerned with effects of surface microgeometries on wetting, aiming at providing instructions for reproducing controllable wettability on artificial surfaces and designing robust superhydrophobic surfaces. First, the origin of edge effect is understood by a thermodynamic approach...
