A Rechargeable Zn-Cu Battery Using a Selective Cation Exchange Membrane
The Daniell cell (Zn-Cu battery) offers several potential advantages over current battery technologies, but is held back by the problems of copper ion (Cu2+) crossover. We resolved this through employing a selective cation ... -
Enzyme Degradable Networks Prepared from a Poly(trimethylene Carbonate)-Peptide Biohybrid
The main objective of this thesis was to develop a biohybrid network with appropriate mechanical properties for a range of soft connective tissue engineering applications that could be degraded solely by the action of the ... -
Stochastic Sampled-data Model Predictive Control for Nonlinear Systems
Stochastic Model Predictive Control (SMPC) has been the focus of intense research in the last years. The objective of SMPC is to design control systems corrupted by stochastic noise. Existing solutions include the ... -
An Injectable Hydrophobic Delivery Formulation Based on Poly(Trimethylene Carbonate) for Therapeutic Angiogenesis
The aim of this thesis was to determine the feasibility of an injectable delivery formulation based on low molecular weight poly(trimethylene carbonate) (PTMC) for localized delivery of vascular endothelial growth factor ... -
Multistep Kinetic Models for Oxygen Reduction Reaction and Platinum Dissolution in Polymer Electrolyte Membrane Fuel Cell
Oxygen electrochemistry on platinum comprises of three well-known phenomena - oxygen reduction reaction (ORR), platinum oxide growth and reduction during cyclic voltammetry (CV) and logarithmic growth of oxides potentiostatically ... -
Hydrolytically Degradable Cationic Flocculants For Improved Water Recovery From Mature Fine Tailings
Oil sands mining operations in Canada produce large volumes of waste tailings that are difficult to dewater using commercial polyacrylamide-based flocculants. Recently, a novel hydrolytically-degradable polymer was synthesized ... -
Reference Electrode Development in Polymer Electrolyte Membrane (PEM) Electrolyzer Assembly for Novel Investigation of Electrodes
Polymer electrolyte membrane electrolyzers (PEMEs) are the key to integrating renewable energy generation with energy storage to reduce greenhouse gas emissions that contribute to global climate change. The commercialization ... -
The Characterization of a Weakly Basic Chemisorbent Polyacrylamide Hydrogel for its Applicability to Downstream Succinic Acid Recovery
Commercial bioproduction of succinic acid has been stimulated by its use as a precursor in the synthesis of commodity chemicals, and the benefits of bioproduction compared to traditional chemical synthesis. However, ... -
Exact Solutions for Oscillatory Shear Sweep Behaviors of Complex Fluids from the Oldroyd 8-constant Framework
(2017-05)Large-amplitude oscillatory shear flow (LAOS) is a popular for studying the nonlinear physics of complex fluids. Specifically, the strain rate sweep (also called the strain sweep) is used routinely to identify the onset ... -
Peroxide-initiated Modification of Polylactic acid (PLA) and Poly(3-hydroxyalkanoates) (PHAs) in the Presence of Allylic and Acrylic Coagents
This thesis investigates the fundamentals of modification of polylactic acid (PLA) and poly(3-hydroxyalkanoates) (PHAs), focusing on improving the understanding of the reactivity of these ... -
Free Radical-Mediated Reactive Extrusion of Commodity Polymers
The objective of this thesis is to improve the melt and solid-state properties of poly (propylene) (PP) and poly(lactide) (PLA) by reactive extrusion. Peroxide-mediated melt-state reactive extrusion in the presence of ... -
Modification of Poly(methyl methacrylate) Surfaces with Azobenzene Groups to Develop a Photoresponsive Surface
Photoswitchable surfaces can be used to reversibly control surface wettability, adsorptivity, and protein adhesion to influence cell interactions at the surface. Control over protein adsorption and cell adhesion is useful ... -
Surface Modification of Cellulose Nanocrystals with CO2-Responsive Polymers via Reversible Deactivation Radical Polymerization
Cellulose is the most abundant natural polymer on Earth. From cellulose, cellulose nanocrystals (CNC) can be obtained through various hydrolysis processes. There is interest in grafting different types of polymers onto CNC ... -
Exact-solution for Cone-plate Viscometry
(2017-08)The viscosity of a Newtonian fluid is often measured by confining the fluid to the gap between a rotating cone that is perpendicular to a fixed disk. We call this experiment cone-plate viscometry. When the cone angle ... -
Fluid Elasticity in Plastic Pipe Extrusion: Loads on Die Barrel
(2017-07)In large thick plastic pipe extrusion, the residence in the cooling chamber is long, and the melt inside the pipe sags under its own weight, causing the product to thicken on the bottom (and to thin on the top). To compensate ... -
Elastomers in Large-Amplitude Oscillatory Uniaxial Extension Revisited
(2017-07)In this work, we subject elastomers to a fixed pre-stretch in uniaxial extension, ε p , upon which a large-amplitude, ε 0 , oscillatory uniaxial extensional (LAOE) deformation is superposed. We find that if both ε p and ε ... -
Elastomers in Oscillatory Uniaxial Extension
(2016-02)In this work, we subject elastomers to a fixed pre-stretch in uniaxial extension, ε p , upon which a large-amplitude, ε 0 , oscillatory uniaxial extensional (LAOE) deformation is superposed. We find that if both ε p and ε ... -
Graphene Nanoplatelet Production Through Non-Ionic Surfactant-Assisted Exfoliation of Graphite
Liquid phase exfoliation of graphite is performed using ultrasonication and shear exfoliation to produce graphene nanoplatelets (GNPs). Ultrasonication is performed using a tip sonicator under power loads ranging from ... -
Mathematical Modelling for Carbon Dioxide Removal from Flue Gas Using Micron-size Water Droplets
