Vacuum chamber for high flux cooling test

We need to create a pure vapor test environment to promote kinetically-limited evaporation from our high flux cooling device.

Nano-engineered surfaces for boiling heat transfer enhancement

Understand boiling enhancement mechanisms and manipulate bubble behaviors with well-defined surface nanostructures

Insulated Cooling with Evaporation and Radiation (ICER)

Passive cooling relying on evaporation and radiation, while offering great energy-saving opportunities, faces challenges with low ambient cooling powers, environmental heating, high water usage, and climate condition constraints.

Passive Subambient Cooling with Evaporation-Insulation Bilayer

A transparent bilayer made of hydrogels and aerogels for passive subambient cooling

Hierarchical high flux evaporative cooler

A new paradigm of phase change heat transfer enabled by a hierarchical evaporator, which favors high volatility, low surface tension liquids rather than water

Coexistence of Contact Line Pinning and Depinning

Textured surfaces are instrumental in water repellency or fluid wicking applications, where the pinning and depinning of the liquid–gas interface plays an important role. We demonstrate that a contact line can exhibit nonuniform behavior even without varying the local energy barrier.

Modeling Evaporation from Nanopores

We present a theoretical framework to elucidate evaporation and transport within nanopores by incorporating non-equilibrium effects due to the deviation from classical kinetic theory.
