Title: Segregation in Multicomponent Droplet Evaporation

Speaker: Detlef Lohse, University of Twente

Abstract: While the evaporation of a single component droplet is well understood, the richness of phenomena in multicomponent droplet evaporation keeps surprising. Lohse's talk will show and explain several such phenomena, namely evaporation-triggered segregation, due to either weak solutal Marangoni flow or gravitational effects, and the evaporation of ternary liquid droplet, which can lead to spontaneous nucleation of droplets consisting of a new phase. He will also show how this new phase can be utilized to self-lubricate the droplet in order to suppress the coffee stain effects. The research shown in this talk combines experiments, numerical simulations, and theory.

Special Note: This talk is part of the The Inaugural Stephen H. Davis Symposium
