Multistage and passive cooling process driven by salinity difference.
Matteo Alberghini,Matteo Morciano,Matteo Fasano,Fabio Bertiglia,Vito Fernicola,Pietro Asinari,Eliodoro Chiavazzo +6 more
TL;DR: A proof-of-concept multistage device, where a net cooling capacity and a temperature difference are demonstrated as long as two water solutions at disparate salinity are maintained, that may help satisfy at least partially the cooling needs in hot, humid regions with naturally available salinity gradients.

Bulk Material Based Selective Infrared Emitter for Sub-Ambient Daytime Radiative Cooling
TL;DR: In this article, the authors proposed a bulk radiative cooler consisting of a 1mm-thick lithium fluoride crystal coated with silver backing, which exhibits a solar absorptance of 4.7% and nearly ideal infrared selectivity with high emission exactly within the atmospheric transmission band (i.e., 8-13 um).

Passive radiative cooling below ambient air temperature under direct sunlight
TL;DR: An integrated photonic solar reflector and thermal emitter consisting of seven layers of HfO2 and SiO2 that reflects 97 per cent of incident sunlight while emitting strongly and selectively in the atmospheric transparency window demonstrates that the cold darkness of the Universe can be used as a renewable thermodynamic resource, even during the hottest hours of the day.

Taming the blackbody with infrared metamaterials as selective thermal emitters.
Xianliang Liu,Talmage Tyler,Tatiana Starr,Anthony F. Starr,Nan Marie Jokerst,Willie J. Padilla +5 more
TL;DR: This Letter demonstrates, for the first time, selective thermal emitters based on metamaterial perfect absorbers and finds that emissivity and absorptivity agree very well as predicted by Kirchhoff's law of thermal radiation.
