Apparent Specific Volumes of Sucrose in Different Aqueous Cosolvent Mixtures at 298.2 K
This article explores research to determine the apparent specific volume of sucrose by measuring the density of sucrose in {cosolvent + water} mixtures at 298.2 K. The study finds that a mean apparent specific volume value of 0.632 cm³.g⁻¹ for sucrose in different aqueous-cosolvent mixtures could be adequate for practical purposes in pharmaceutical industries.

The C₂H₂ + NO₂ Reaction: Implications for High Pressure Oxidation of C₂H₂/NOx Mixtures
Article discussing an experimental and kinetic modeling study of the interaction between C₂H₂ and NOx under flow reactor conditions in the intermediate temperature range (600–900 K), high pressure (50–60 bar), and for stoichiometries ranging from reducing to strongly oxidizing. The results show that presence of NOx serves both to sensitize and inhibit oxidation of C₂H₂.

Comments on "Solubility and Dissolution Thermodynamic Data of Cefpiramide in Pure Solvents and Binary Solvents"
Abstract: Errors are found in the mathematical correlation based on the combined Jouyban-Acree and Modified Apelblat model for describing the variation in the mole fraction solubility of cefpiramide with temperature and solvent composition for the binary aqueous-ethanol solvent system. The equation coefficents given by Tang and coworkers, when substituted into the model equation, do not yield the authors' calculated mole fraction solubilities of cefpiramide.

Experimental and Computational Studies of the Kinetics of the Reaction of Hydrogen Atoms with Carbon Disulfide
Article discussing an investigation of the reaction of H + CS₂ products. The reaction was found to be pressure dependent and in the fall-off region or near the low pressure limit. Transition state theory yields an estimate for the high-pressure limit of addition over 290–300 K of 1.3 × 10−9 exp( −7.2 kJ mol −1 /RT) cm3 molecule −1 s −1. Uncertainties are discussed in the text.

Generalized molecular solvation in non-aqueous solutions by a single parameter implicit solvation scheme
Article presenting a systematic parametrization protocol for the Self-Consistent Continuum Solvation (SCCS) model resulting in optimized parameters for 67 non-aqueous solvents. The parametrization is based on a collection of ≈6000 experimentally measured partition coefficients, which were collected in the Solv@TUM database presented here. The accuracy of the optimized SCCS model is comparable to the well-known universal continuum solvation model (SMx) family of methods, while relying on only a single fit parameter and thereby largely reducing statistical noise.
