A long-standing law of thermodynamics turns out to have a loophole at the smallest scales. Researchers have shown that quantum engines made of correlated particles can exceed the traditional ...

Challenging centuries-old assumptions about thermodynamics, a new study published in Physical Review Letters has shown that it is theoretically possible to design a heat engine that achieves maximum ...

Engineers at Oregon State University have taken waste heat and used it to run a cooling system to improve the energy efficiency of diesel engines. This heat-actuated cooling system will probably find ...

For two centuries, engineers have trusted a simple rule to predict how heat flows through solids, from jet-engine blades to smartphone chips. Now a set of carefully designed experiments has revealed a ...
