For two centuries, students have learned that heat flows and engines work according to rigid limits that no machine can beat.

Fractal analysis has emerged as a powerful tool for investigating thermal conductivity in porous media. By utilising complex mathematical constructs, researchers are now able to elucidate the ...

Imagine a device that lets you move heat very quickly from one place to another, yet needs no power, no electricity, no pumps and no moving parts. You might think, "Sure, that's what metals like ...

Thermoelectric coolers (TECs) are common and (look) simple, but simple (and usefully accurate) design models and equations for them are less common. This design model has served well in a variety of ...
