Passive Radiative Cooling
Develop durable, weather-resistant radiative cooling panel to slash HVAC loads
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
Energy Conversion
Optimize interfacial heat and mass transfer to maximize the efficiency of converting energy from one form to another
Bubble-free water electrolysis
Design and optimize a bubble-free capillarity-driven flow cell for electrolysis. Investigate the effect of utilizing various electrodes and membranes with different geometries and materials
Transport-Based Modeling of Nucleation on Electrodes
Fundamental understanding of the nucleation process, which is critical to system optimization, remains limited as prior works generally focused on the thermodynamics and have not considered the coupling between surface geometries and different forms of transport in the electrolytes.
