Modeling the Transport and Volumetric Properties of Solutions Containing Polymer and Electrolyte with New Model [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 2018
A new theoretical model based on the local composition concept (TNRF-mNRTL model) was proposed to express the short-range contribution of the excess Gibbs energy for the solutions containing polymer and electrolyte. This contribution of interaction along

Application of NRTL activity coefficient model to describe the kinetics of gas adsorption

Open Chemistry, 2013
Abstract The Non-Random Two-Liquid activity coefficient model is applied to describe the kinetics of pure gas adsorption on energetically heterogeneous solid surfaces. The surface energetic heterogeneity has been represented by the Gaussian-like function of the adsorption energy distribution.

Experimental determination and prediction of liquid-solid equilibria for binary (methyl palimitate + naphthalene) mixture

MATEC Web of Conferences, 2013
Solid-liquid equilibria for binary mixtures of {Methyl palmitate (1) + Naphthalene (2)} were measured using differential scanning calorimeter (DSC). Simple eutectic behaviours for this system are observed.

Estimation of Activity and Molar Excess Gibbs Energy of Binary Liquid Alloys Pb-Sn, Al-Sn and In-Zn from the Partial Radial Distribution Function Simulated by Ab Initio Molecular Dynamics

Metals
For the present, it is difficult to obtain thermodynamic data for binary liquid alloys by experimental measurements. In this study, the molecular dynamics processes of the binary liquid alloys Pb50-Sn50, Al50-Sn50, and In50-Zn50 were simulated by using ...

Equilibrium Solubility of Ammonium Nitrate and Potassium Nitrate in (NH₄NO₃-KNO₃-H₂O-C₂H₅OH) Mixed System

Crystals
The polymorphism of ammonium nitrate has significantly limited its application. Incorporating potassium nitrate into crystals of ammonium nitrate is one of the most commonly used methods to inhibit its polymorphic transition.

Measurement and Correlation of Vapor–Liquid Equilibrium of Mixtures of 1,2-Propanediol or 1,4-Butanediol + 1,8-Diazabicyclo(5.4.0)undec-7-ene at 30 kPa

Clean Technologies
In this study, vapor–liquid equilibrium (VLE) experimental data were measured for two binary solvents based on 1,8-diazabicyclo(5.4.0)undec-7-ene (DBU), which can be used as a new CO2-binding organic liquids (CO2-BOLs) solvent.
