Thermodynamics of Various Entropies in Specific Modified Gravity with Particle Creation
Advances in High Energy Physics, 2018 We consider the particle creation scenario in the dynamical Chern-Simons modified gravity in the presence of perfect fluid equation of state p=(γ-1)ρ. By assuming various modified entropies (Bekenstein entropy logarithmic entropy, power law correction ...

Thermodynamics in modified Brans–Dicke gravity with entropy corrections
European Physical Journal C: Particles and Fields, 2018 In this paper, we investigate the thermodynamics in the frame-work of recently proposed theory called modified Brans–Dicke gravity (Kofinas et al. in Class Quantum Gravity 33:15, 2016).

Leibniz and the Second Law of Thermodynamics
Teorie vědyThis article is a loose sequel to a previous article Leibniz and the First Law of Thermodynamics (Theory of Science 46(1):89–114, 2024). But this time I analyze in detail the modern debate between Leibniz, Newton, Clarke, and Descartes, anticipating ...

"A calorie is a calorie" violates the second law of thermodynamics
Nutrition Journal, 2004 The principle of "a calorie is a calorie," that weight change in hypocaloric diets is independent of macronutrient composition, is widely held in the popular and technical literature, and is frequently justified by appeal to the laws of thermodynamics ...

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy
Advanced Engineering Materials, EarlyView.This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Infrared Cloaking, Stealth, and the Second Law of Thermodynamics
Entropy, 2012 Infrared signature management (IRSM) has been a primary aeronautical concern for over 50 years. Most strategies and technologies are limited by the second law of thermodynamics.

Karl Popper and the Mechanisms of Hydrogen Embrittlement
Advanced Engineering Materials, EarlyView.Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Radiation Entropy Bound from the Second Law of Thermodynamics
Entropy, 2012 It has been suggested heuristically by Unruh and Wald, and independently by Page, that at given energy and volume, thermal radiation has the largest entropy. The suggestion leads to the corresponding universal bound on entropy of physical systems.
