Entropy and the Second Law of Thermodynamics—The Nonequilibrium Perspective

open access: yesEntropy, 2020
An alternative to the Carnot-Clausius approach for introducing entropy and the second law of thermodynamics is outlined that establishes entropy as a nonequilibrium property from the onset.

Onsager's Non-Equilibrium Thermodynamics as Gradient Flow in Information Geometry. [PDF]

open access: yesEntropy (Basel)
We consider Onsager’s non-equilibrium thermodynamics from the perspective of the gradient flow in information geometry. Assuming Onsager’s reciprocal relations, we can regard his phenomenological equations as gradient-flow equations and ...

Symplectic Foliation Structures of Non-Equilibrium Thermodynamics as Dissipation Model: Application to Metriplectic Nonlinear Lindblad Quantum Master Equation. [PDF]

open access: yesEntropy (Basel), 2022
The idea of a canonical ensemble from Gibbs has been extended by Jean-Marie Souriau for a symplectic manifold where a Lie group has a Hamiltonian action.

Kinetic Description of Viral Capsid Self-Assembly Using Mesoscopic Non-Equilibrium Thermodynamics. [PDF]

open access: yesEntropy (Basel)
The self-assembly mechanisms of various complex biological structures, including viral capsids and carboxysomes, have been theoretically studied through numerous kinetic models.

Nonlinear Non-Equilibrium Thermodynamics Based on the Ehrenfest-Klein Model. [PDF]

open access: yesEntropy (Basel), 2020
Nonlinear non-equilibrium thermodynamic relations have been constructed based on the generalized Ehrenfest-Klein model. Using these relations, the behavior of the entropy and its production in time at arbitrary deviations from equilibrium has been ...

Multiscale Thermodynamics

open access: yesEntropy, 2021
Multiscale thermodynamics is a theory of the relations among the levels of investigation of complex systems. It includes the classical equilibrium thermodynamics as a special case, but it is applicable to both static and time evolving processes in ...

The Maximum Entropy Production Principle: Its Theoretical Foundations and Applications to the Earth System [PDF]

open access: yes, 2010
The Maximum Entropy Production (MEP) principle has been remarkably successful in producing accurate predictions for non-equilibrium states. We argue that this is because the MEP principle is an effective inference procedure that produces the best ...

Recovering phytochemicals from a brewery by-product: a sustainable reuse proposal using a lactic acid-based deep eutectic solvent [PDF]

open access: yesSustainable Food Technology
Hot trub (HT), a nutrient-rich by-product of beer production, remains underutilized despite its potential for resource recovery. This study explores the valorization of HT, producing two phytochemical-rich extracts with potential functional applications ...

Time in Thermodynamics [PDF]

open access: yes, 2011
It is often claimed, or hoped, that some temporal asymmetries are explained by the thermodynamic asymmetry in time. Thermodynamics, the macroscopic physics of pressure, temperature, volume, and so on, describes many temporally asymmetric processes.

Modeling the transformation of І and ІІІ types kerogen by the method of entropy maximization

open access: yesВісник Харківського національного університету імені В.Н. Каразіна. Серія Геологія. Географія. Екологія, 2021
Purpose, methods and research methodology. The aim of the work is to calculate and compare the trends of transformation of organic matter of I-A and III-A type kerogen, which is in contact with organic and inorganic gases in the process of immersion of ...
