In 1813, Napoleon's failed campaign against Russia led to a coup d'état in Paris, France. Prussia and Austria then invaded France. Among the troops guarding Paris at the time was Sadie Carnot.

One famous limit of thermodynamics is that heat engines, like steam engines and internal combustion engines, must be less efficient than a Carnot heat engine (a heat engine cycle designed by French ...

Heat engines are ubiquitous as they lie at the core of cars, aircraft, refrigerators, power plants and miniature motors. But they are currently limited by Carnot's maximum efficiency rule, according ...

The engine works by taking heat from the hot reservoir, converting some of it into useful work, and rejecting the remaining heat to the cold reservoir. The thermodynamic cycle followed by the engine ...

Engineers have reported on the development of a microscopic motor operating between two thermal baths, that is, a micro Carnot engine. In a recent study published in Nature Physics, ICFO researchers ...

Since its inception about two centuries ago thermodynamics has sparkled continuous interest and fundamental questions. According to the second law no heat engine can have an efficiency larger than ...

Researchers at the Indian Institute of Science (IISc.) and Jawaharlal Nehru Centre for Advanced Scientific Research (JNCASR) have cracked an age-old thermodynamic puzzle by devising a novel micro heat ...
