Prof. Justin Burton's lab uncovers how flowing liquid molecules begin to slip against a solid surface
When liquids flow near a solid wall, the first layer of liquid molecules are typically stuck so that they do no slip against the surface. However, just like two solids can slip past one another when pushed hard enough, leading to friction, a liquid can also slip against a solid. New experimental measurements from the Burton lab detail how this is possible for slippery, hydrophobic surfaces.
