(Phys.org)—A team of researchers with the University of California and SRI International has developed a new type of cooling device that is both portable and efficient. In their paper published in the ...

(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 ...

We have known the technology for heating food for centuries, and we have been improving it more and more. But why haven’t we yet discovered a small appliance to cool food in a short time? That’s just ...

A new cooling innovation developed by scientists pumps away heat continuously using layers of flexing thin films. The design is based on the electrocaloric effect, in which an electric field causes a ...

Ever-growing in their use, air conditioning systems use refrigerants that are powerful greenhouse gases. But independent teams in Europe and the US reckon they may have found a more environmentally ...

As necessary as cooling technologies are, we’re still operating on an outdated technology that can be considered a significant contributor to global warming and greenhouse gas emissions. Currently, ...

A novel blend of ferroelectric polymers developed by a team led by Pennsylvania State University could be used to provide on demand cooling for chips and small scale systems. These so called ...

UCLA materials scientists have developed a compact cooling technology that can pump away heat continuously using layers of flexing thin films. The design is based on the electrocaloric effect, in ...

In a nutshell: Traditional air conditioners and heat pumps employ refrigerant gas to cool down or heat up homes and buildings, bringing potential harm to the environment. A team of European scientists ...

Electroactive polymers react to forces, deformations, and temperature changes with electrical signals. They can also deform or change their temperature under electrical voltage. Targeted temperature ...
