A micro-scale quantum heat engine that converts thermal energy to usable work under near-zero temperatures has paved the way ...

Recent improvements in our understanding of how the principles of thermodynamics apply in the quantum realm could give a ...

A machine smaller than a grain of sand has turned heat into useful work near absolute zero, opening a new path to far more ...

Heat engines convert heat into work—for example, moving a piston in a certain direction. For an engine to be 100% efficient, when the process is reversed—the piston returns to its original state—there ...
