Evaporation of liquid marbles

Evaporation of liquid marbles

Internship Description

Interestingly, when a drop of water is rolled on a powder made of hydrophobic particles, the particles adsorb onto the liquid-vapor interface, creating what are known as ‘liquid marbles’. Liquid marbles can roll around; collide gently, etc., without releasing water.
Recently, we observed that the rates of evaporation of water from liquid marbles could be higher or lower in comparison to bare water drops depending on the choice of hydrophobic particles.  To understand what factors control these phenomena, we will conduct systematic experiments and theoretical analysis.​​​

Deliverables/Expectations

The VSRP intern will work with a senior graduate student and learn the following skills:

Laboratory experiments: wet chemistry (silanation of glass beads), optical imaging

Theory: data analysis, data plotting

 

We expect the intern to be driven by curiosity, hard working, and thrive in a multicultural work environment.
