3D Woven Lattices as Multi-functional Heat Exchanger

Unmet NeedPorous materials are a widely used heat exchanger for common household items such as radiators and refrigerators. However, these materials are typically focused on optimizing at most one or two physical/chemical properties (heat transfer, fluidic permeability, electrical conductivity, etc.). As a result, these materials tend to underperform...
