Researchers at the University of Illinois at Urbana-Champaign have developed a new technology for switching heat flows 'on' or 'off'. The findings were published in the article "Millimeter-scale liquid metal droplet thermal ...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Their study has been published in Physical Review Letters.
It may not be obvious while lying in the sun on a hot summer's day, but a considerable amount of heat is also coming from below you – emanating from deep within the Earth. This heat is equivalent to more than three times ...
(Phys.org)—Researchers have built the hottest thermal diode to date, which operates at temperatures of more than 600 K (326 °C). Thermal diodes may serve as the building blocks of future thermal computers, which could ...
As spacecraft become larger, the heat they produce also increases. That means vehicles built for long-term space exploration need more efficient cooling systems.
The precise control of electron transport in microelectronics makes complex logic circuits possible that are in daily use in smartphones and laptops. Heat transport is of similar fundamental importance and its control is ...
For decades, scientists have theorized that the movement of Earth's tectonic plates is driven largely by negative buoyancy created as they cool. New research, however, shows plate dynamics are driven significantly by the ...
(Phys.org)—Illustrating the unusual way things work on the nanoscale, scientists have designed a new nanoelectromechanical system (NEMS) that produces mechanical motion due to the interactions between electrons—yet unlike ...
Gold had long been considered a non-magnetic metal. But researchers at Tohoku University recently discovered that gold can in fact be magnetized by applying heat.
One of the biggest problems in designing electronic components is getting rid of excess heat. Now, A*STAR researchers have found a simple way to vary the heat flow in graphene, a breakthrough that will improve attempts to ...
