A thermodynamic muscle model and a chemical basis for A.V. Hill's muscle equation

Journal of Muscle Research & Cell Motility, 2000
Direct measurements of a relationship between force and actin-myosin biochemistry in muscle suggest that molecular forces in active muscle rapidly equilibrate among. not within, individual myosin crossbridges [Baker et al. (1999) Biophys J 77: 2657 2664].

Thermodynamic inconsistencies in and accuracy of chemical equations of state for associating fluids

Industrial & Engineering Chemistry Research, 1992
Hydrogen bonding is usually taken into account through the use of chemical theory. Thermodynamic properties of associating systems are calculated by solving the equations for chemical and physical equilibria simultaneously. Recently, many equations of state have been proposed for associating components with a built-in chemical theory based on the ...

The Gibbs–Helmholtz Equation and the Thermodynamic Consistency of Chemical Absorption Data

Industrial & Engineering Chemistry Research, 2012
The Gibbs–Helmholtz (G-H) equation connects vapor–liquid equilibrium (VLE) and calorimetric data. If experimental measurements for the heat of solution are not available, they may be estimated through the G-H equation. Further, if both VLE and heat-of-solution data are available, their mutual thermodynamic consistency can be evaluated through the G-H ...

Representation of standard chemical thermodynamic properties of isomer groups by equations

The Journal of Physical Chemistry, 1990
Since the standard chemical thermodynamic properties of isomer groups in a homologous series are found to be linear functions of the number of carbon atoms, the number of parameters required to represent them as a function of temperature and carbon number is greatly reduced. The existing tables for C{sub p}{sup 0}(I{sub n}), S{sup 0}(I{sub n}), and the

The computer‐derivation of thermodynamic equations Part III. Chemical systems

The Canadian Journal of Chemical Engineering, 1989
AbstractAn algorithm, THERMODER4, based on Jacobians, is presented for automating the symbolic derivation of expressions for thermodynamic derivatives for chemical systems, to complement algorithms given previously for unrestricted simple and complex systems.

Closed form for the equations of chemically reacting flows under local thermodynamic equilibrium

Physical Review E, 2005
We present a closed form for the governing equations of chemically reacting flows under local thermodynamic equilibrium, which rigorously takes into account effects of elemental (de)mixing. To this end, we show that when chemistry is fast, the diffusion fluxes of elements and species enthalpies can be expressed as explicit linear functions of gradients

Thermodynamic fluctuations and chemical chaos in a well-stirred reactor: A master equation analysis

The Journal of Chemical Physics, 1993
The stochastic analysis of a chemical system obeying to mass-action kinetics and giving rise to deterministic chaos is carried out using the master equation approach. Quantitative comparison with the predictions of the deterministic description based on the rate equations shows that the system’s attractor and the probabilistic properties are robust ...

Solvation thermodynamics and the physical–chemical meaning of the constant in Abraham solvation equations

Chemosphere, 2012
Abraham solvation equations find widespread use in environmental chemistry. Until now, the intercept in these equations was determined by fitting experimental data. To simplify the determination of the coefficients in Abraham solvation equations, this study derives theoretical expressions for the value of the intercept for various partition processes ...

An Accurate Equation-of-State Model for Thermodynamic Calculations of Chemically Reactive Carbon-Containing Systems

Journal of Energetic Materials, 2010
We present an equation-of-state (EOS) model that allows for reliably computing the thermodynamics and chemical compositions of reactive carbon-containing systems over a wide range of temperatures and densities covering both high pressures up to tens of gigapascals and moderate pressures.
