Universal restrictions to the conversion of heat into work derived from the analysis of the Nernst theorem as a uniform limit
(IOP Publishing, 2003-07-08)
The relationship between the Nernst theorem and the Kelvin-Planck statement of the second law is revisited. We put forward the fact that the exchange of entropy is uniformly vanishing as the temperature goes to zero. The ...
