Thermodynamic Properties of Solutions of Amino Acids and Related Substances
The effect of temperature on the thermodynamic ionization constants of compounds with dipole moments greater than those of the a-amino acids has not heretofore been studied. In this paper results are given for glycylglycine and c-aminocaproic acid, two substances with similar dipole moments. Measurements are also included for aspartic acid, which has recently been studied at 25” in cells withou...
متن کاملAn Evaluation of Four Electrolyte Models for the Prediction of Thermodynamic Properties of Aqueous Electrolyte Solutions
In this work, the performance of four electrolyte models for prediction the osmotic and activity coefficients of different aqueous salt solutions at 298 K, atmospheric pressure and in a wide range of concentrations are evaluated. In two of these models, (electrolyte Non-Random Two-Liquid e-NRTL and Mean Spherical Approximation-Non-Random Two-Liquid MSA-NRTL), association between ions of opposit...
متن کاملCation distributions and thermodynamic properties of binary spinel solid solutions
A general model is presented to enable the calculation of the cation distribution and thermodynamic properties of any binary solid solution between oxide spinels containing 2*, 3* and 4* cations. The model includes the effect ofdisordering enthalpy which depends linearly on the degree of disorder. In addition there are important contributions to the thermodynamic properties from the size mismat...
متن کاملModeling the Thermodynamic Properties of Solutions Containing Polymer and Electrolyte with New Local Composition Model
A new theory model based on the local composition concept (TNRF-modified NRTL (TNRF-mNRTL) model) was developed to express the short-range contribution of the excess Gibbs energy for the solutions containing polymer and electrolyte. An equation represented the activity coefficient of solvent was derived from the proposed excess Gibbs energy equation. The short-range contribution of interaction ...
متن کاملSpectral, kinetic, and thermodynamic properties of Cu(I) and Cu(II) binding by methanobactin from Methylosinus trichosporium OB3b.
To examine the potential role of methanobactin (mb) as the extracellular component of a copper acquisition system in Methylosinus trichosporium OB3b, the metal binding properties of mb were examined. Spectral (UV-visible, fluorescence, and circular dichroism), kinetic, and thermodynamic data suggested copper coordination changes at different Cu(II):mb ratios. Mb appeared to initially bind Cu(II...
