Researchers at the U.S. Department of Energy’s Ames Laboratory have designed and built an advanced device that uses small quantities of magnetocaloric materials to cool objects or inside enclosures ...

Image: This colorized scanning electron micrograph shows a cube of germanium attached to a membrane. The four small light blue rectangles at the midpoints of the membrane perimeter are chip-scale ...

A team of CU Boulder engineers has developed a scalable manufactured metamaterial—an engineered material with extraordinary properties not found in nature—to act as a kind of air conditioning system ...

A two-layered paint that reflects infrared light while maintaining its colour could help keep buildings and vehicles cool under hot sun. This could help reduce energy used in cooling, such as by air ...

How can light be used to cool atoms and molecules? How can light be used to cool atoms and molecules? Lasers are known to burn things, fix eyes, and dance on powerpoint presentations. But they can ...

Within quantum mechanics, there has been an observable limit (the quantum backaction limit) on how low you can cool an object experimentally. Up until very recently, that limit had not been challenged ...

A heat-reflecting, futuristic supermaterial that looks like a roll of plastic wrap could one day cool both houses and power plants without using any energy, according to a new study. Unlike solar ...

“Absolute zero” isn't just cold — it's still. It is the point at which the motion of the atoms that make up an object stops completely, when the object has no energy left to give. The rules of physics ...

In the last few decades, physicists have found ways to super-cool objects so that their atoms are at a near standstill, wrestling small objects such as clouds of millions of atoms, or nanogram-scale ...
