DESCRIPTION:Speakers: Frédéric van Wijland ()\nIn equilibrium fluids\, w
 etting is controlled by the competition of three surface tensions between 
 the three phases (liquid\, gas\, solid). When the particles comprising the
  fluid become self-propelled\, the question of wetting begins with a prope
 r definition of surface tension (which may not be unique out of equilibriu
 m). I will present a robust mechanics-based definition for surface tension
 . I will use this definition to explore the properties of a droplet at con
 tact with a solid. It will appear that the angle of contact of an active d
 roplet is no more governed by the Young-Dupré equation.\n\nWith Y. Zhao\,
