Molecular theory of partial molar volume and its applications to biomolecular systems
The partial molar volume (PMV) is a thermodynamic quantity which contains important information about the solute-solvent interactions as well as the solute structure in solution. Additionally, the PMV is the most essential quantity in the analysis of the pressure effect on chemical reactions. This article reviews the recent developments in molecular theories of the PMV, especially the reference...
متن کاملModeling the Surface Tension and the Interface of Ten Selected Liquid Mixtures: Correlation, Prediction, and the Influence of Using Partial Molar Volume
This work investigates the modeling of the surface tension and the interface of liquid mixtures. Nine binary liquid mixtures of (DMSO+alcohols), (2-Propanol+2,2,4-trimethylpentane), (Tetrahydrofuran+2-Propanol), (Tetrahydrofuran+2,2,4-trimethylpentane), and (ethano+glycerol) are considered. Additionally, one ternary liquid mixture of (Tetrahydrofuran+2-Propanol+2,2,4-trimethylpenta...
متن کاملAn Accurate Correlation to Estimate Saturated Molar Volume of Liquids
There are a number of techniques available to estimate saturated-liquid molar or specific volumes or densities of liquids. In this study, a new empirical correlation is presented to calculate volume of saturated liquids as a function of critical volume, reduced temperature and acentric factor. An optimization algorithm is utilized to obtain unknown parameters of this correlation by fitting them...
متن کاملCompare clinical Presentation of complete Molar Pregnancy and partial Molar Pregnancy ( 2006-2018)
Objective: Molar pregnancy is classified as one of the diseases groups as a type of Gestational Trophoblastic Disease (GTD) which is emerged from placenta. Hydatitiform moles are diagnosed one per 1500-2000 pregnancies in the United States. There seems to be a large variation in mole development and its frequency in Far East Asia is higher than western industrial. Mole is divided into two ty...
متن کاملFast Computation of Solvation Free Energies with Molecular Density Functional Theory: Thermodynamic-Ensemble Partial Molar Volume Corrections.
Molecular density functional theory (MDFT) offers an efficient implicit-solvent method to estimate molecule solvation free-energies, whereas conserving a fully molecular representation of the solvent. Even within a second-order approximation for the free-energy functional, the so-called homogeneous reference fluid approximation, we show that the hydration free-energies computed for a data set o...
