A sophisticated halide material can go from diode to non-diode and back depending on the temperature differential across its terminals. How an advanced material can become both p- and n-material based ...

Driving force An experiment has confirmed that an oscillating temperature gradient boosts heat flow in fluids. (Courtesy: iStock/Mervana) Physicists in the Czech Republic have shown that heat flows ...

In a new Nature Physics paper, researchers report the first experimental observation of the transverse Thomson effect, a key thermoelectric phenomenon that has eluded scientists since it was predicted ...
