Event details

How does a drop of water rest on a solid surface? The textbook answer to this simple question has unphysical implications. It suggests that a meager drop of water applies a divergent stress to its substrate at the contact line where solid, liquid and vapor meet. We measure the deformation of a soft elastic solid near a contact line and find that the solid sidesteps this singularity by mimicking a liquid. If time permits, I will discuss striking similarities between the wetting of simple liquids and the spreading of cohesive cells.

About Condensed Matter lunchtime seminars

This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
