Title: Salt-rimmed glass: is it a creep or is it a weirdo?
Abstract: Confined evaporation of multiphase multicomponent systems has recently garnered significant attention not only due its numerous practical applications, but also as a model system to study complex interface growth and interfacial self-assembly dynamics. Here, we focus on a canonical system for confined evaporation – evaporation from one end of a liquid-filled capillary. In the first part of the talk, I’ll focus on the evaporation of a binary fluid mixture, where the composition-dependent evaporation kinetics was found to exhibit three different temporal regimes. Along the way, we revisit the age-old question: “Is evaporation really a slow process?” In the second part, we focus on the evaporation of salty liquids, where the liquid front exhibits non-monotonic dynamics, unlike multifluid systems. Curiously, we further observe that evaporation, in fact, is not the dominant mechanism of liquid loss in such systems. Finally, we will also attempt to answer the question: “Do salt crystals experience rush hour?”
