A 200-year physics rule fails at atomic scales, researchers say
For two centuries, students have learned that heat flows and engines work according to rigid limits that no machine can beat.
THE cycle proposed by Dr. J. S. Haldane (NATURE, August 29, p. 326) as a standard of comparison for steam engine performance can be shown quite readily on a temperature-entropy chart, and thus be ...
A British engine manufacturing start-up is taking inspiration from a 200 year-old principle of thermodynamics to achieve a significant breakthrough in engine technology, one which promises a ...
Power boost: a quantum heat engine in synthetic diamond. (Courtesy: Jonas Becker) Physicists have in recent years built a number of microscopic heat engines to investigate how the laws of ...
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 ...
ON p. 326 of NATURE for August 29 appears an abstract of a paper by Dr. J. S. Haldane, which he read before the Institution of Mining Engineers on June 16. In this paper he has “thrown to the winds” ...
