Engines, laptops and power plants generate waste heat. Thermoelectric materials, which convert temperature gradients to electricity and vice versa, can recover some of that heat and improve energy efficiency. A team of scientists at the Department of Energy’s Oak Ridg...

Quasiparticles—excitations that behave collectively like particles—are central to energy applications but can be difficult to detect. Recently, however, researchers have seen evidence of quasiparticles called negative trions forming and fading in a layer of semiconducting mate...

When it’s up and running, the ITER fusion reactor will be very big and very hot, with more than 800 cubic meters of hydrogen plasma reaching 170 million degrees centigrade. The systems that fuel and control it, on the other hand, will be small and very cold. Pellets of frozen gas will be shot int...
