In a hot summer Sunday braai or shisa nyama (South African barbecue), if you don't finish your favorite beverage quickly, the ice cubes will melt and the drink will get warm—undoubtedly spoiling your ...

(Nanowerk News) Heat flows from hot to cold objects. When a hot and a cold body are in thermal contact, they exchange heat energy until they reach thermal equilibrium, with the hot body cooling down ...

Researchers have developed a method to control the direction of heat flow in crystals. This miniature device could eventually be used to create advanced thermal-management systems in electronic ...

New work could help design electronic devices in which heat can be guided in certain directions, minimizing heat loss ...

We’re all familiar with semiconductor diodes, whose function is to allow electricity to easily flow in one direction and impede its progress in the other. A thermal diode performs a similar gating ...

How a Virginia Tech research team constructed its novel thermal diode. Test results of the thermal diode. Electrical engineers are obviously very familiar and comfortable with the basic diode, a ...

Scientists have discovered that applying an electric field to certain ceramics can dramatically redirect how heat moves through them.

Scientists in the United States have discovered an electric field method to improve heat ...

Scientists at Oak Ridge National Laboratory have found that applying an electric field to a specialized ceramic can nearly ...

Tokyo, Japan – Unwanted heating of electronic components hinders the performance of many devices. For example, the processing speed and memory available to silicon-based computer chips depend strongly ...
