Advances in simple crystals for thermoelectric technology

Space probes, gas pipelines, and other applications require an ongoing source of thermoelectric power without direct human maintenance, but current technologies for the corresponding energy conversion are inefficient. Now, ...

A quantum step to a heat switch with no moving parts

Researchers have discovered a new electronic property at the frontier between the thermal and quantum sciences in a specially engineered metal alloy—and in the process identified a promising material for future devices ...

How the mold influences a chocolate bar's crystalline structure

When enjoying a chocolate bar, most people don't think about how the molecules within it are organized. But different arrangements of the fats in chocolate can influence its taste and texture. Now, researchers reporting in ...
