Diffusion of dissolved gases in molten condensation polymers

An Analytical Equation of State for Molten Polymers

An analytical equation of state (EOS) developed by Ihm-Song-Mason (ISM) has been applied tocalculate some thermophysical properties of molten polymers including Poly (1-octene) (PO), Poly (vinylmethyl ether) (PVME), Poly (vinyl chloride) (PVC), and Poly (styrene) (PS). Three temperature-dependentparameters of the ISM EOS have been determined based on the alternative scaling constants, dispersiv...

Effect of Greenhouse Gases Dissolved in Seawater

A molecular dynamics simulation has been performed on the greenhouse gases carbon dioxide and methane dissolved in a sodium chloride aqueous solution, as a simple model of seawater. A carbon dioxide molecule is also treated as a hydrogen carbonate ion. The structure, coordination number, diffusion coefficient, shear viscosity, specific heat, and thermal conductivity of the solutions have been d...

Bose–Einstein Condensation in Dilute Gases

Bose-Einstein Condensation in Dilute Atomic Gases

The material presented here consists of lecture notes written for a five two-hour sections course given during the 2004 edition of the Brazilian School on Statistical Mechanics. The topics covered are 1. Bose-Einstein condensation of trapped ideal gases; 2. Effective two-body interactions and exact results in the Gross-Pitaevski limit; 3. Atomic structure effects, including “Feshbach resonances...
