Ionic Liquids: Length Scale Selects Directionality of Droplets on Vibrating Pillar Ratchet (Adv. Mater. Interfaces 9/2014)
Source abstract
Abstract
N. V. Lavrik and co-workers demonstrate in article 1400337 that arrays of tilted pillars, such as the one in the cover image, exhibit asymmetric wettability under dynamic conditions. When vibrated vertically, such asymmetrically structured surfaces induce directional transport of droplets at room temperature. Depending on the pillar length scale, droplets move in either the same direction as the pillar tilt or against the pillar tilt.
