VOLUME-BASED THERMODYNAMICS GLOBAL PHASE STABILITY ANALYSIS
Chemical Engineering Communications, 2006In this study we propose a method for phase stability analysis at pressure and temperature specifications, in the frame of a “volume-based” thermodynamics. The formulation of the tangent plane distance (TPD) criterion in terms of the Helmholtz free energy is used in this work for testing phase thermodynamic stability at p-T conditions, using component ...

Volume fluctuation thermodynamics of polymer solutions
Macromolecules, 1991The idea of «volume fluctuation thermodynamics» is formally developed to show in general terms how solution properties are affected by finite compressibility and by the mismatch in pure-component equation of state ...

Thermodynamics of rubber elasticity at constant volume
Transactions of the Faraday Society, 1971Thermoelastic measurements at constant volume are reported for a series of natural rubber samples. The energy component of the stress supported by the network is more or less independent of the network cure at a value of fe/f= 0.12±0.02. The energy component of the stress is independent of whether the measurements are made in the dry or in the swollen ...

Holography, magnetic fields and thermodynamic volumes
2015This dissertation explores the application of gauge/gravity duality to gauge theories of interest in condensed matter physics, as well as thermodynamic volumes. ? Four?dimensional gravity with a U(1) gauge field, coupled to various fields in asymptotically anti?de Sitter spacetime, provides a rich arena for the holographic study of the strongly coupled

Free volume concept and polymer solutions thermodynamics
Die Makromolekulare Chemie, 1975AbstractAfter briefly recalling previous work on thermodynamics of polymer solutions, we tentatively present a van der Waals‐like relationship for the excess enthalpy of mixing for polymer solutions, applied recently by Bagley et al. to simple mixtures and we derive the corresponding value of χH, the enthalpic part of the Flory‐Huggins parameter χ.

Thermodynamics of associated solutions with volume effects
Fluid Phase Equilibria, 1983Abstract A model based on a slight modification of Flory's theory for polymer solutions, and which takes into account volume effects on the associated species due to interactions with the solvent, is suggested. Fitted to liquid-vapor equilibrium data, it shows results which agree in general better than other models.

The thermodynamics of volume change and creep
Matériaux et Constructions, 19681 With some exceptions, early observers of creep of concrete assumed that time-dependent strain is due to plastic flow or viscous flow. It is now becoming understood that creep, like shrinkage, is a phenomenon depending on adsorption and desorption of water and related phenomena.
