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

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 with the long-range contribution of interaction (Pitzer-Debye-Hückel equation), configurational entropy of mixing (Flory-Huggins relation)...

Superconductor Cobaltites

Since the discovery of high transition-temperature (high Tc ) superconductivity in layered copper oxides [1], they have held the pole position in the race for achieving higher Tc [2]. In this race many different compounds which contain copper oxide layers has been examined. Although there are reports of Tc s up to 185K for very rare phases of complex compounds like (Sn1.0Pb0.5In0.5)Ba4Tm5Cu7O20...

Cation Exchange Nanocomposite Membrane Containing Mg(OH)2 Nanoparticles: Characterization and Transport Properties

In this study, ion exchange nanocomposite membranes was prepared by addition of Mg(OH)2 nanoparticles to a blend containing sulfonated polyphenylene oxide and sulfonated polyvinylchloride via a simple casting method. Magnesium hydroxide nanoparticles were synthesized via a facile sono-chemical reaction and were selected as filler additive in fabrication of ion exchange nanocomposite membranes. ...

Transport Properties of Refrigerant Mixtures: Thermal Conductivity

In the present work, the integral equations method is used to calculate transport properties of polar fluids. For this goal, we use the Stockmayer potential and examine theoretically the thermal conductivity of several refrigerant mixtures such as R125+R134a, R125+R32, R125+R152a, R134a+R32, R152a+R32, R134a+R143a, and R125+R143a. We solve numerically the Ornstein-Zernike (OZ) equation usin...
