Sentences with phrase «droplet on solid surfaces»

This conclusion was experimentally validated by actively sliding a water droplet on solid surfaces with micro-holes and micro-pillars of various sizes while simultaneously measuring the resultant sliding friction forces.

Scientists in the last 20 years have learned to control the movement of liquid droplets on a solid surface by breaking the wetting symmetry that results from the impact of a droplet on a surface.

«Wettability plays a key role in determining the equilibrium contact angles, contact angle hysteresis, and adhesion between a solid surface and liquid, as well as the retraction process of a liquid droplet impinged on the surface,» explained Doo Jin Lee, lead author, and a postdoctoral researcher in the Department of Materials and Engineering at Seoul National University.

Recently, the same group of physicists showed that the percentage of space occupied by solids for a unit - area surface can indeed significantly affect liquid droplets» sliding behaviour on surfaces with micro-pillar structures.
