Refrigerator cools by flexing artificial muscles

The new technology is based on an incredibly simple principle

04-Apr-2024 - There is room for just one small bottle in the world’s first refrigerator that is cooled with artificial muscles made of nitinol, a nickel-titanium alloy. But the mini-prototype that the team led by professors Stefan Seelecke and Paul Motzki will be presenting at the Hannover Messe from 22 to 26 ...

Research team uses artificial muscles to develop an air conditioner for the future

14-Mar-2019 - It can be used to cool or heat the air in a room or to cool or heat liquids. And it looks like something that Q – the tech specialist and gadgeteer in the James Bond films – might have come up with. The prototype device, which has been developed by a research team led by Professors Stefan ...

The Coldest Chip in the World

22-Dec-2017 - Physicists at the University of Basel have succeeded in cooling a nanoelectronic chip to a temperature lower than 3 millikelvin. The scientists from the Department of Physics and the Swiss Nanoscience Institute set this record in collaboration with colleagues from Germany and Finland. They used ...

A cooling system that works without electricity

07-Sep-2017 - It looks like a regular roof, but the top of the Packard Electrical Engineering Building at Stanford University has been the setting of many milestones in the development of an innovative cooling technology that could someday be part of our everyday lives. Since 2013, Shanhui Fan, professor of ...

Engineered 'sand' may help cool electronic devices

14-Jul-2016 - Baratunde Cola would like to put sand into your computer. Not beach sand, but silicon dioxide nanoparticles coated with a high dielectric constant polymer to inexpensively provide improved cooling for increasingly power-hungry electronic devices. The silicon dioxide doesn't do the cooling itself. ...

Engineers invent transparent coating that cools solar cells to boost efficiency

23-Sep-2015 - Every time you stroll outside you emit energy into the universe: Heat from the top of your head radiates into space as infrared light. Now three Stanford engineers have developed a technology that improves on solar panel performance by exploiting this basic phenomenon. Their invention shunts away ...

Researchers produce first demonstration of matter wave technique that could cool molecules

20-Aug-2015 - Researchers from the University of Southampton have demonstrated for the first time a new laser cooling method, based upon the interference of matter waves, that could be used to cool molecules. The current technique of cooling atoms down from room temperature to the ultra-cold regime using ...

Graphene-based film can be used for efficient cooling of electronics

13-Jul-2015 - Researchers at Chalmers University of Technology have developed a method for efficiently cooling electronics using graphene-based film. The film has a thermal conductivity capacity that is four times that of copper. Moreover, the graphene film is attachable to electronic components made of ...

Scientists detect 'fingerprint' of high-temp superconductivity above transition temperature

Method may help identify conditions needed to get current flowing at higher temperatures

01-Sep-2009 - A team of U.S. and Japanese scientists has shown for the first time that the spectroscopic "fingerprint" of high-temperature superconductivity remains intact well above the super chilly temperatures at which these materials carry current with no resistance. This confirms that certain conditions ...

Semiconductors for Cool Computers

20-Jul-2009 - Computers with no need of cooling? They haven't come into existence yet. However, physicists of the University of Würzburg are paving the way for them: In the American scientific journal "Science", the researchers now present a semiconductor that transmits electric current without heating up in ...
