Implementing Demons and Ratchets
Entropy, 2017 Experimental results show that ratchets may be implemented in semiconductor and chemical systems, bypassing the second law and opening up huge gains in energy production.

The Deep Physics Behind the Second Law: Information and Energy As Independent Forms of Bookkeeping
Entropy, 2004 : Even after over 150 years of discussion, the interpretation of the second law of thermodynamics continues to be a source of confusion and controversy in physics.

Entropy, 2015 The literature reports the proofs that entropy is an inherent property of any system in any state and governs thermal energy, which depends on temperature and is transferred by heat interactions.

Second Thoughts on the Second Law [PDF]
, 2018 We speculate whether the second law of thermodynamics has more to do with Turing machines than steam pipes. It states the logical reversibility of reality as a computation, i.e., the fact that no information is forgotten: nature computes with Toffoli-, not NAND gates.

Entropy, Holography, and the Second Law [PDF]
Physical Review Letters, 2004 The geometric entropy in quantum field theory is not a Lorentz scalar and has no invariant meaning, while the black hole entropy is invariant. Renormalization of entropy and energy for reduced density matrices may lead to the negative free energy even if no boundary conditions are imposed.

A Kinetic Perspective on k - ϵ Turbulence Model and Corresponding Entropy Production
Entropy, 2016 In this paper, we present an alternative derivation of the entropy production in turbulent flows, based on a formal analogy with the kinetic theory of rarefied gas.

Entropy, 2018 MHD free convection inside a triangular-wave-shaped corrugated porous cavity with Cu-water nanofluid is numerically studied with the finite element method. The influences of the Grashof number ( 10 4 ≤ Gr ≤ 10 6 ), Hartmann number (
