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.
