Accounting for Temperature Effects When Predicting Molecular Weight and Composition Distribution for Gas-Phase Polyethylene Produced Using a Multi-Site Catalyst
(Wiley, 2022-07-19)A dynamic model is developed for gas-phase ethylene/1-hexene polymerization with a three-site hafnocene catalyst. The model accurately predicts molecular weight and comonomer composition distributions for fifteen lab-scale ... -
USING MICROFLUIDICS TO STUDY THE BEHAVIOUR OF MAGNETOTACTIC BACTERIA UNDER ENVIRONMENTAL STRESSORS
This work presents an evaluation of Magnetotactic Bacteria’s (MTB) response to fluidic stressors. MTB have been previously proven to demonstrate great potential as carriers for therapeutic agents within the human body. ... -
Adaptive Feedback Control of Generalized Hamiltonian Systems With Unstructured Components
This dissertation considers the problem of feedback controller design for systems represented in non-exact generalized Hamiltonian form. The generalized Hamiltonian representation of dynamical systems has some properties ... -
Fabrication of Graphene Oxide and Composite Membranes for Isotopic Water Mixture Separation
Isotopes of water have a key role in various applications, including nuclear power and Canada Deuterium Uranium (CANDU) reactors. However, large-scale separation of isotopic water mixtures is presently performed using ... -
Study of Tantalum Carbide Supported Iridium-Based Catalyst and Sulfonated Phenylated Polyphenylene as Materials for Polymer Electrolyte Membrane Water Electrolysis
The use of iridium-based electrocatalyst supported on tantalum carbide (IrOx/TaC) was investigated for polymer electrolyte membrane water electrolysis (PEMWE) applications. The IrOx/TaC electrocatalyst was used to prepare ... -
Steady-State Modelling for Natural Gas Transport Network Optimization
Natural gas is an essential global energy resource. Large volumes of gas are transported using transmission pipelines and energized using compressors. Several operational optimization opportunities arise due to the immense ... -
Toll-Like Receptor 2 and the Early Chronic Inflammatory and Fibrotic Macrophage Response to Adsorbed Damage Associated Molecular Patterns
The foreign body reaction (FBR) is an aberrant wound healing process that occurs in response to an implanted biomaterial, which can lead to the implant failing prematurely. Recently, damage-associated-molecular-patterns ... -
Study of TaC Supported Ir-Based Oxygen Evolution Reaction Electrocatalysts Synthesized by Surfactant-Mediated Method
The physical and electrochemical properties of Tantalum carbide (TaC) as a potential support for oxygen evolution reaction (OER) electrocatalysts were investigated. It was first ball milled for 7 and 14 days in order to ... -

(Wiley, 2021-12-10)A process for the well-controlled growth of acrylates by Cu-mediated polymerization has been developed, with macroinitiator synthesized continuously in a copper tubular reactor and subsequently chain-extended in a semibatch ... -
Kinetic Modeling of Radical Homo-, Co- and Terpolymerization in Alcohol/Aqueous Solutions
Multi-functional polymers used for personal care products can be modified post-production or be used “as-is” to simplify formulations, while providing the same properties as a mixture of polymers. Typical compositions ... -
The Influence of PHEMA Hydrogel Compressive Modulus and Chemistry on Lens Epithelial and Neutrophil-Like Cell Behaviours Associated with Posterior Capsular Opacification
During cataract surgery, the impaired lens is removed and replaced with an artificial intraocular lens (IOL). Patients can experience a complication called posterior capsular opacification (PCO) that is corrected through ... -
