Traditionally Nonwetting Surface Made to Wet Mercury
Liquid-Gas Interface, Research
We present a surface-engineering approach that turns all liquids highly wetting, including ultra-high surface tension fluids such as mercury.
Coexistence of Contact Line Pinning and Depinning
Liquid-Gas Interface, Research
Textured surfaces are instrumental in water repellency or fluid wicking applications, where the pinning and depinning of the liquid–gas interface plays an important role. We demonstrate that a contact line can exhibit nonuniform behavior even without varying the local energy barrier.
