Heat has always been something we thought we understood. From baking bread to running engines, the idea seemed simple: heat ...

Anomalous” heat flow, which at first appears to violate the second law of thermodynamics, gives physicists a way to detect ...

New research suggests that thermal switching in smart polymer solutions may depend less on polymer conformation than ...

Control of heat flow is crucial for thermal logic devices and thermal management, with theoretical exploration preceding limited experimental progress in actively controlling heat flow. The device ...

The big picture: Researchers from the University of California have developed a first-of-its-kind, solid-state thermal transistor that could one day be used to better control heat in electronic ...

A rare mineral from a 1724 meteorite defies the rules of heat flow, acting like both a crystal and a glass. Thanks to AI and quantum physics, researchers uncovered its bizarre ability to maintain ...

Using a thermal sensor smaller than a grain of sand, engineers have measured the vibrations, or phonons, within individual molecules. Imagine you are playing the guitar -- each pluck of a string ...

This redirected heat flow boosted the PTE effect by aligning temperature changes with variations in how the material responds to heat—essentially enhancing current production. Discover the latest in ...

From smartphones to supercomputers, electronics have a heat problem. Modern computer chips suffer from microscopic “hotspots” with power density levels that exceed those of rocket nozzles and even ...
