Intensive thermodynamic parameters in nonequilibrium systems [PDF]

open access: yesPhysical Review E, 2007
Considering a broad class of steady-state nonequilibrium systems for which some additive quantities are conserved by the dynamics, we introduce from a statistical approach intensive thermodynamic parameters (ITPs) conjugated to the conserved quantities. This definition does not require any detailed balance relation to be fulfilled.

A consideration of the correct calculation of thermodynamic parameters of adsorption [PDF]

open access: yesJournal of the Serbian Chemical Society, 2007
The Langmuir and Freundlich isotherm equations have been widely used for interpreting various adsorption processes. There are, however, many serious mistakes in the literature in determination or calculation of thermodynamic parameters, especially in the

Stochastic thermodynamics with odd controlling parameters [PDF]

open access: yesPhysical Review E, 2019
Stochastic thermodynamics extends the notions and relations of classical thermodynamics to small systems that experience strong fluctuations. The definitions of work and heat and the microscopically reversible condition are two key concepts in the current framework of stochastic thermodynamics.

Parameter Estimation Strategies in Thermodynamics [PDF]

open access: yesChemEngineering, 2019
Many thermodynamic models used in practice are at least partially empirical and thus require the determination of certain parameters using experimental data. However, due to the complexity of the models involved as well as the inhomogeneity of available data, a straightforward application of basic methods often does not yield a satisfactory result ...
