First theorized in 1938, heat's wave-like flow through superfluids, known as "second sound", has proven difficult to directly observe. Now, a new technique has finally done it, and could be used to ...

Researchers in China have developed a new methodology to improve the performance of solar-powered air source heat pumps. The ...

This is supported by old, magnetised crustal rock. It is possible to characterise the heat transfer from the interior of the planet by measuring the heat flow at the surface. This is the objective of ...

Oliveira Junior. "This led us to uncover a fundamental connection between heat flow and uniquely quantum properties. We found that quantum systems reveal their special traits simply by exchanging ...

Scientists at the Technical University of Denmark have created a novel microscope that substantially improves the measurement of heat flow in materials, according to a study published in Science ...

Heat always spontaneously flows from a hotter place to a colder one – so says the second law of thermodynamics. But within an extremely sparse gas, the opposite may be possible, with heat ...

Using voltage to model temperature and current to model heat flow, he’s set up a model for his home to compare the behavior of a heat pump and a propane furnace. A switch model already in ...

With Heat Flow Calorimetry (HFC) small heat effects can be measured during an isothermal measurement of the sample. Mainly used for the lifetime prediction of gunpowder. Large sample size, up to a ...
