RIKEN physicists have fabricated a nanoscale ‘heat engine’ that uses a property of electrons known as spin as the effective working medium 1. It is promising for exploring the development of ...

Heat has always been something we thought we understood. From baking bread to running engines, the idea seemed simple: heat spreads out smoothly, like water soaking through a sponge. That simple ...

Faster is not better when it comes to engine coolant flow rate. The purpose of a radiator is to support heat transfer, which is a time-dependent process. As Flex-a-Lite explains, to move the heat from ...

Heat is a byproduct of combustion. Both air-cooled and water-cooled engines need to dissipate that heat to keep the engine from running too hot. Can piston rings play a role in managing that heat?

The strange world of quantum mechanics just got a little stranger with the discovery that a magnetic field can control the flow of heat from one body to another. First predicted nearly 50 years ago, ...
