Laser Transmission Welding of Polybutylene Terephthalate and Polyethylene Terephthalate Blends
(20100831)Laser Transmission Welding (LTW) involves localized heating at the interface of two pieces of plastic (a laser transparent plastic and laser absorbing plastic) to be joined. It produces strong, hermetically sealed welds ... 
Latent Amine Cures of Brominated Poly(isobutylenecoisoprene)
(20100202)The allylic bromide functionality within brominated poly(isobutylenecoisoprene), or BIIR, alkylates primary amines repeatedly to generate thermoset products at reaction rates that are too fast to support commercial rubber ... 
Leukocyte Response to ElastinLike Polypeptide Coatings
(20131015)Small diameter synthetic vascular grafts have yet to be clinically successful due to luminal narrowing from thrombosis and intimal hyperplasia. Current attempts to address this issue include the development of materials ... 
Living Radical Polymerization in Aqueous Dispersed Systems with WaterSoluble Catalysts
(20151003)Living radical polymerization is an important technique for synthesizing advanced macromolecules including block copolymers. Since its discovery in the early 1990s the capability of the field has expanded with new types ... 
Living/controlled Polymerization Conducted in Aqueous Based Systems
(20070925)In the last decade processes known as living/controlled radical polymerizations (L/CRP) have been developed which permit the synthesis of highvalue specialty polymers. Currently, the three processes that have demonstrated ... 
Living/Controlled Radical Polymerization in a Continuous Tubular Reactor
(20101221)Significant advances have been made in the understanding of living/controlled radical polymerization processes since their discovery in the early 1990’s. These processes enable an unprecedented degree of control over ... 
Load bearing regenerative repairs for the cartilaginous soft tissue of the intervertebral disc
(20140917)Cartilaginous load bearing soft tissues such as the nucleus pulposus in the intervertebral disc are affected by degenerative diseases and physical injury, which if not treated early can initiate a progressive decline in ... 
Low melting point and amphiphilic polymer microspheres for therapeutic protein delivery
(20151209)Biodegradable microspheres have been extensively studied for controlled and minimally invasive in situ protein delivery. Their small size and thus ready injectability makes this device extremely popular for localized ... 
Macromolecular Orientation of Rigid Dumbbells in Shear Flow
We use molecular modeling to study the nonequilibrium behaviour of polymeric fluids. Specifically, we explore the macromolecular orientation induced by shear flow fields. We choose the simplest molecular model, the rigid ... 
Mathematical model for ethane pyrolysis in an industrial furnace
(20140923)Ethane pyrolysis is an important industrial process that occurs by passing ethane and steam through radiant coils (tubes) in gasfired furnaces to produce ethylene and other light olefins. Undesirable side reactions that ... 
A Mathematical Model for the Devolatilization of EPDM Rubber in a Series of Steam Stripping Vessels
(20121024)A steadystate mathematical model for the stripping section of an industrial EPDM rubber production process was developed for a threetank process, and two fourtank processes. The experiments that were conducted to determine ... 
Mathematical Modeling of Arborescent Polyisobutylene Production in Batch Reactor Using Novel Material Balance and Monte Carlo Methods
