Super-amphiphobic coatings with sub-ambient daytime radiative cooling—Part 2: Cooling effect under real conditions

Near-room-temperature waste heat recovery through radiative cooling for both daytime and nighttime power generation

“…This range of h can stand for various situations outdoors. 50–54 Fig. 1(e) reveals that the value of η rad was equal to 1 when the temperature difference ( T surf − T amb ) was zero, meaning that all of the dissipated heat was contributed by P radiative .…”
