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 ...

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.

Thermodynamics of rotating Bardeen black holes: Phase transitions and thermodynamics volume
Physical Review D, 2019We investigate the thermodynamical properties of the rotating Bardeen black holes characterized by mass $m$, the spin parameter $a$, and the magnetic charge $g$. We calculate exact expressions of the Hawking temperature, mass, entropy, and heat capacity.

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.

Thermodynamics of binary mixtures: some excess volumes
The Journal of Chemical Thermodynamics, 1974Abstract Excess volumes of methylene chloride+pyridine, +α-picoline, +aniline, and +o-toluidine at 298.15 and 303.15 K and of chloroform+pyridine, +α-picoline, +aniline, and +o-toluidine at 303.15 K have been measured as a function of composition by a dilatometric method.

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 ...

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.

Macromolecular conformational volume and thermodynamics of crystal melting
Polymer, 1985Abstract Conformational parts of the thermodynamical function change on melting, in particular the conformational volume ΔVconf, the conformational entropy ΔSconf and the pressure variation of the latter are analysed for an ideal polymer crystal. These quantities can be calculated from the data for low molecular compounds combined with the three ...

Isodromic criterion of thermodynamic similarity for orthobaric volumes
Soviet Physics Journal, 1978The new criterion of thermodynamic similarity obtained for orthobaric volumes can be used to calculate and correlate their values for little-investigated substances as well as to determine whether a chemical compound belongs to one group of thermodynamic similarity or another.
