Components of the Thermodynamic Functions of Iron

Physical Review, 1956
The thermodynamic functions enthalpy, entropy, and free energy of alpha and gamma iron are determined from existing data. These functions are resolved into their magnetic, lattice, and electronic components on the basis of additivity of the respective specific heat components.

Components in Chemical Thermodynamics

Journal of Chemical Education, 1995
Chemical equations are actually matrix equations, and this has important implications for their thermodynamic treatment. The fundamental equation for chemical thermodynamics for a chemical reaction system can be written in terms of species, but at chemical equilibrium, it has to be written in terms of components.

Consistent Enthalpies of the Hydrate Formation and Dissociation Using Residual Thermodynamics

Journal of Chemical and Engineering Data, 2019
Kinetics of the hydrate phase transition is implicit functions of the free-energy change of the phase transition and the related dynamics of associated mass and heat transport.

On the Thermodynamics of Strongly Degenerate Two‐Component Plasmas

physica status solidi (b), 1986
AbstractA generalisation of Gell‐Mann‐Brueckner's formula is derived for two‐component systems of charged particles with any mass ratio and multi‐valley degeneracy. Higher order rs‐contribution are determined in the random phase approximation. Numerical values are given especially for hydrogen plasmas and for optically excited electron—hole plasmas in ...

Rational Strategy to Stabilize an Unstable High‐Efficiency Binary Nonfullerene Organic Solar Cells with a Third Component

Advanced Energy Materials, 2019
Long device lifetime is still a missing key requirement in the commercialization of nonfullerene acceptor (NFA) organic solar cell technology. Understanding thermodynamic factors driving morphology degradation or stabilization is correspondingly lacking.

THERMODYNAMIC CALCULATION OF n-COMPONENT EUTECTIC MIXTURES

International Journal of Modern Physics C, 2004
This paper presents a simple numerical method to calculate the eutectic mixture composition and melting temperature. Using a Newton–Raphson method to solve the nonlinear problem, the calculation is possible for n-component eutectic. We tested this algorithm on inorganic and organic mixtures.

Thermodynamics of Three-Component Systems

Nature, 1952
ALTHOUGH relations of the type where a is activity, n is number of moles, and the suffixes denote the components, are by no means new1, they have been little exploited. Further types such as and

Thermodynamics of solutions of propanols in nonassociating components

Thermochimica Acta, 1985
Abstract The spectroscopic and thermodynamic properties of solutions of propanols in various nonassociating components can be described well by an associated solution model in which the association of alcohol molecules into open-chain and cyclic hydrogen-bonded species and the formation of complexes between the terminal hydroxyl group of the alcohol ...

Thermodynamic Properties of High-Temperature Air Components

1996
The paper gives a synthetic description of the basic methods to calculate the high-temperature thermodynamic properties of air species. Emphasis is given to the strong dependence of the electronic partition function and the thermodynamic properties of atomic species on the number of electronic levels taken into account.

Thermodynamics of solutions of methanol and solvating components

Thermochimica Acta, 1982
Abstract A model is proposed to correlate the excess Gibbs free energies and excess enthalpies of binary solutions of methanol and a solvating component. Solution nonideality from ideal solutions is given by the sum of the chemical contribution term, which is due to self-association of methanol and solvation between methanol and a nonassociating ...
