Thermodynamics of solution of lysozyme crystals
Archives of Biochemistry and Biophysics, 1969Abstract The solubility of crystalline hen egg white lysozyme in 1.7 m (10%) NaCl has been studied in the pH range 2.6–5.0 and at temperatures of 21.7, 29.5, and 42.7 °. The pH dependence of solubility can be used to evaluate the difference between the number of protons bound by a lysozyme molecule in the crystal and in solution.

Thermodynamics of Aqueous Solutions of Parabens
Journal of Pharmaceutical Sciences, 1978The solubility of a related series of parabens was determined in water at four temperatures. The parabens chosen were the methyl through n-butyl p-hydroxybenzoates, and the temperature variations were 5 degrees increments from 25 to 40 degrees. These solutes are useful preservatives, especially combinations of the methyl and propyl ester derivatives ...

Thermodynamics of aqueous solutions of dodecyldimethylethylammonium bromide
Journal of Colloid and Interface Science, 2007The thermodynamic properties of the aqueous solutions of dodecyldimethylethylammonium bromide (DEDAB) were determined as a function of concentration by means of direct methods. Dilution enthalpies at 298 and 313 K, densities and sound velocities at 298 K were measured, allowing the determination of apparent and partial molar enthalpies, volumes, heat ...

The entropy of a pure substance has a true zero, that of its pure crystalline solid form at zero (Kelvin) temperature, according to the third law of thermodynamics. The entropy, and the free energies that involve it, are the least obvious of the thermodynamic functions, and textbooks of general thermodynamics should be consulted for a full explanation.

Thermodynamic Analysis of Multicomponent Solutions
1964Publisher Summary This chapter discusses thermodynamic analysis of multicomponent solutions. An exhaustive consideration of the properties of solutions and theory of electrolytes requires a treatise far beyond the scope of this chapter, in which one shall be concerned primarily with only certain thermodynamic problems specifically implied by the ...

Thermodynamics of adsorbed solutes
Colloids and Surfaces, 1983Abstract By considering the surface region of a solution of a surface active solute as a separate phase, the condition of equilibrium, which relates bulk concentration, surface concentration, and surface tension, can be obtained by equating chemical potentials for each component in the system.

Thermodynamics of polydimethylsiloxane solutions
Journal of the Chemical Society, Faraday Transactions 1: Physical Chemistry in Condensed Phases, 1973Solvent chemical potentials and heats of dilution have been obtained for systems containing polydimethylsiloxane and solvents comprising normal and branched alkanes, aromatic hydrocarbons and dimethylsiloxane oligomers. Using the Flory–Huggins approximation to eliminate the combinatorial contribution to ΔSM, the results are expressed as concentration ...

Mixing and Solution Thermodynamics
2017In nature, we rarely find pure components or elements. We live in a world made of mixtures; therefore, we should shift our attention to mixtures components in solids, liquids, and gases. Because of this, we are more interested in the thermodynamics of mixing.
