TLDR
In this article, the authors developed a general theory which accounts for interactions between chemical species within a mean-field approach using activity coefficients, which is general and holds for any mean field expression of the interactions leading to lower bounded free energies.Abstract:
All current formulations of nonequilibrium thermodynamics of open chemical reaction networks rely on the assumption of non-interacting species. We develop a general theory which accounts for interactions between chemical species within a mean-field approach using activity coefficients. Thermodynamic consistency requires that rate equations do not obey to standard mass-action kinetics, but account for the interactions with concentration dependent kinetic constants. Many features of the ideal formulations are recovered. Crucially, the thermodynamic potential and the forces driving non-ideal chemical systems out of equilibrium are identified. Our theory is general and holds for any mean-field expression of the interactions leading to lower bounded free energies.read more

What to Learn from a Few Visible Transitions’ Statistics?
TL;DR: In this paper , the authors consider an observer who records a time series of occurrences of one or several transitions performed by a system, under the assumption that its underlying dynamics is Markovian.

Information thermodynamics for deterministic chemical reaction networks.
TL;DR: In this article , the authors extend the scope of information thermodynamics to deterministic bipartite chemical reaction networks, composed of two coupled subnetworks sharing species but not reactions.
Housekeeping and excess entropy production for general nonlinear dynamics
TL;DR: This work proposes a housekeeping/excess decomposition of entropy production for general nonlinear dynamics in a discrete space, including chemical reaction networks and discrete stochastic systems, and extends the optimal transport theory of discrete systems to nonlinear and nonconservative settings.

Kinetic derivation of the Hessian geometric structure in chemical reaction networks
TL;DR: In this paper , the authors reveal the Hessian geometry which underlies chemical reaction networks and demonstrate how it originates from the interplay of stoichiometric and thermodynamic constraints.

Stochastic thermodynamics, fluctuation theorems and molecular machines
TL;DR: Efficiency and, in particular, efficiency at maximum power can be discussed systematically beyond the linear response regime for two classes of molecular machines, isothermal ones such as molecular motors, and heat engines such as thermoelectric devices, using a common framework based on a cycle decomposition of entropy production.

General mass action kinetics
TL;DR: The principal result of this work shows that there exists a simply identifiable class of kinetic expressions, including the familiar detailed balanced kinetics as a proper subclass, which ensure consistency with the extended thermodynamic conditions.

Equalities and Inequalities: Irreversibility and the Second Law of Thermodynamics at the Nanoscale
TL;DR: The reason we never observe violations of the second law of thermodynamics is in part a matter of statistics: when ∼1023 degrees of freedom are involved, the odds are overwhelmingly stacked against the possibility of seeing significant deviations away from the mean behavior.

Network theory of microscopic and macroscopic behavior of master equation systems
TL;DR: In this paper, a general microscopic and macroscopic theory is developed for systems which are governed by a (linear) master equation, and the results are obtained mostly by application of some basic theorems of mathematical graph theory.
