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 ...

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 ...

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” ...

Prof. SUN Qingping (left) and Research Assistant Prof. LI Qiao (right), both from the Department of Mechanical and Aerospace Engineering at HKUST, demonstrate their newly developed Ti₇₈Nb₂₂ elastic ...

As the global push for carbon neutrality accelerates, managing the massive energy demands and waste heat of industrial sectors has become a critical ...

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 ...

IN a paper on Carnot's Cycle and the Efficiency of Heat Engines, reported in NATURE, August 29, Dr. J. S. Haldane comes to the astonishing conclusion that “the Carnot cycle is radically in efficient” ...

Thermoelectrics using nanostructures offers the potential of getting very close to the carnot limit of efficiency using very light weight systems for convert heat to electricity. Early versions of ...

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 ...
