Abstract:

We designed and microfabricated an ultrathin nanoporous membrane as an experimental platform to fundamentally probe the evaporation kinetics. Our nano device consisted of an ultrathin free-standing membrane (~200 nm thick) containing an array of nanopores (pore diameter ~100 nm). It realizes accurate and yet non-invasive interface temperature measurement and decouples the interfacial transport resistance from the thermofluidic resistance in the liquid phase and the diffusion resistance in the vapor phase.
