Event Details & Abstract: 

Liquids and solids tend to stick to each other.  When a liquid droplet sticks to a solid surface we call it wetting.  When a solid particle sticks to a solid surface we call it adhesion.  The classic coarse-grained descriptions of these two phenomena are quite distinct from each other.  Both descriptions assume that solid objects undergo very little deformation during wetting and adhesion.  In this talk, I will show how this assumption breaks down when the solids are soft enough and how wetting and adhesion really are not that different after all.** Joint with the MSE seminar series
