''Cold'' Leidenfrost effect
ORAL
Abstract
An evaporating Leidenfrost drop placed on a hot substrate can levitate on its own vapor if the temperature of the substrate is high enough. We discuss the possibility to decrease this critical Leidenfrost temperature using a super-hydrophobic coating. Measuring adhesion and observing the liquid-solid interface, we suggest a possible explanation for this ``cold'' regime of levitation.
