(Phys.org)—Researchers have built an electrocaloric refrigerator the size of a beverage coaster that can generate a temperature difference of about 2 K between the hot and cold ends of the device. The cooling mechanism, ...
Thermoelectric cooling is a solid-state refrigeration process where the heat in an electrically conductive material is transferred using the material's own conduction electrons without any need for the gaseous coolants, such ...

(Phys.org)—In 1912, chemist Walther Nernst proposed that cooling an object to absolute zero is impossible with a finite amount of time and resources. Today this idea, called the unattainability principle, is the most widely ...
Climate change is wreaking havoc on the environment. While the main culprit is carbon emissions, urban heat islands—exacerbated by dark roofs and pavements—make the effect of global warming even worse on the urban dwellers.
