Quantum thermal transistor can control heat currents

(Phys.org)—Researchers have designed a quantum thermal transistor that can control heat currents, in analogy to the way in which an electronic transistor controls electric current. The thermal transistor could be used in ...

Turning desalination waste into a useful resource

The rapidly growing desalination industry produces water for drinking and for agriculture in the world's arid coastal regions. But it leaves behind as a waste product a lot of highly concentrated brine, which is usually disposed ...

Can heat be controlled as waves?

A growing interest in thermoelectric materials—which convert waste heat to electricity—and pressure to improve heat transfer from increasingly powerful microelectronic devices have led to improved theoretical and experimental ...

Getting more electricity out of solar cells

(Phys.org) —When sunlight shines on today's solar cells, much of the incoming energy is given off as waste heat rather than electrical current. In a few materials, however, extra energy produces extra electrons—behavior ...
