Effect of polymer architecture on the gas separation performance of PIM-1 membranes
Abstract: Molecular simulations are used to demonstrate the effects of chain architectureson the gas separation performance of PIM-1 membranes. Four different architectures(linear, H-shape, star, and dendritic) were considered to investigate the transport propertiesof four industrially relevant gases (CO2, CH4, O2, and N2). The results obtainedfor the linear PIM-1 agree well with the available experimental data. The simulationsindicate that it is indeed possible to tune the free volume morphology of PIM-1 membranesby …

A Model for Plastic-Hydrolytic Damage Bioresorbable Polymer Composites
Abstract: This paper explains and assesses a recently developed constitutive model for elastic-damage that may sustain plastic-hydrolytic damage. When a metallic material is subjected to plastic strain, voids and microcracks in the metal matrix start to form, develop, and merge. This is what causes ductilitydegradation in metals. Only a few of the many models that have been presented to depict ductile failure have done a thorough analysis of the entire damage …
