Title: Acrobatics of non-stick droplets
Abstract: Making drops non-wetting increases dramatically their mobility, compared to the situations we are used to. We'll describe a few consequences of this statement, with a particular focus on jumping droplets: two non-stick drops can transfer their surface energy into kinetic energy when they merge, and thus can jump from their substrate. The materials achieving such a property might be antifogging, since condensing water is likely to be evacuated without external source of energy. We’ll discuss to what extent this optimistic view is science-fiction - wearing glasses at the time of covid, we realize how non-antifogging common materials are...
