Ever since the invention of water mills in antiquity, through the development of the steam engine in the 18th century, and up to today’s turbines, many power generators rely on the principle of ...

Researchers at MIT have built a highly efficient thermophotovoltaic cell that, when paired with renewable resources, efficiently converts incoming photons—particles of light—to electricity. It’s an ...

In and out: An illustration of the quantum engine as a piston, showing the piston compressed when the particles in the gas exist as bosonic molecules and expanded when they are individual fermionic ...

Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS Heat engines, converting heat into useful work, are vital in modern society. With advances in nanotechnology, ...
