Researchers in Sweden have shown that electrical tuning of passive radiative cooling can be used to control the temperature of a material at ambient temperatures and air pressure. Passive radiative cooling occurs when thermal energy leaves an object in the form of infrared radiation. The amount they emit depends on its ability to absorb infrared […]
Chicago University researchers have designed a building material that adjusts its emission of infrared colour and heat according to outdoor temperatures, which could provide low-energy temperature regulation for buildings. In a recent paper published in Nature Sustainability, researchers explained that their non-flammable electrochromic building material contains a layer that can reversibly shift between solid […]
