Cold neutrons used in hot pursuit of better thermoelectrics

Thermoelectric devices are highly versatile, with the ability to convert heat into electricity, and electricity into heat. They are small, lightweight, and extremely durable because they have no moving parts, which is why ...

Breaking down the Wiedemann-Franz law

A study exploring the coupling between heat and particle currents in a gas of strongly interacting atoms highlights the fundamental role of quantum correlations in transport phenomena, breaks the Wiedemann-Franz law, and ...

Thermoelectric nanodevice based on Majorana fermions is proposed

In March 1938, the young Italian physicist Ettore Majorana disappeared mysteriously, leaving his country's scientific community shaken. The episode remains unexplained, despite Leonardo Scascia's attempt to unravel the enigma ...

Converting heat into electricity with pencil and paper

Thermoelectric materials can use thermal differences to generate electricity. Now there is an inexpensive and environmentally friendly way of producing them with the simplest tools: a pencil, photocopy paper, and conductive ...

Turning background room temperature heat into energy

Every time we convert energy from one form to another, part of that energy is lost in the form of heat. Trying to efficiently get that energy back is very difficult once it is lost to the environment. Thermoelectric devices ...
