Researchers have shown theoretically that, in highly ordered materials, heat can flow toward warmer regions without violating the laws of thermodynamics. Their work could help design electronics that ...
Fourier's well-known heat equation, introduced in 1822, describes how temperature changes in space and time when heat flows through a material. In general, this formulation works well to describe heat ...
WEST LAFAYETTE, Ind. – Researchers are applying the same “hydrodynamic transport model” used to study flow in fluids to explain heat transport in a solid semiconductor, with potential implications for ...

Three recent studies offer deeper understanding of thermodynamic behaviors with potential to impact materials engineering and energy systems. One shows how increasing elemental diversity in layered ...
To understand how heat normally flows, you could study the second law of thermodynamics – or wrap your hands around a hot mug of coffee. Both tell us that heat tends to flow toward cooler regions. As ...
The new equations explain why and under which conditions heat propagation can become fluid-like, rather than diffusive. Credit: Michele Simoncelli, EPFL The new equations explain why and under which ...
