Passive Daytime Radiative Cooling of Silica Aerogels
Nanomaterials, 2023 Silica aerogels are one of the most widely used aerogels, exhibiting excellent thermal insulation performance and ultralow density. However, owing to their plenitude of Si-O-Si bonds, they possess high infrared emissivity in the range of 8–13 µm and are potentially robust passive radiative cooling (PRC) materials.

PASSIVE NIGHTTIME RADIATIVE COOLING USING BLACK SILICON
Proceeding of Proceedings of the 10th International Symposium on Radiative Transfer, RAD-23 Thessaloniki, Greece, 12–16 June 2023, 2023 Decarbonized and low energy technologies for heat management and conversion are a key milestone for climate change mitigation. Cooling is one of the major fields where such technologies are required. Passive radiative cooling in its nighttime and daytime versions is therefore a promising technology to achieve those goals.

Superhydrophobic bilayer coating for passive daytime radiative cooling
Nanophotonics, 2023 Abstract Passive radiative cooling is an energy-free cooling method by exchanging thermal radiation with the cold universe through the transparent atmospheric window. Spectrum tailoring of the radiative cooler is the key to daytime radiative cooling in previously reported works. In addition, radiative coolers with large-scale fabrication

Designer SiO2 Metasurfaces for Efficient Passive Radiative Cooling
Advanced Materials Interfaces, 2023 AbstractIn recent years, an increasing number of passive radiative cooling materials are proposed in the literature, with several examples relying on the use of silica (SiO2) due to its unique stability, non‐toxicity, and availability. Nonetheless, due to its bulk phonon‐polariton band, SiO2 presents a marked reflection peak within the atmospheric ...
