Fabrication of a Bioactive Scaffold Material for Meniscus Tissue Engineering
(2013-11-20)Injuries to the meniscus are a common and important source of mobility issues in the knees of young active individuals, as well as elderly individuals. Conventional treatments for these injuries involve surgical resections ... -
Fabrication of novel power sources for portable and wearable devices
Practical applications of portable and wearable electronics is linked with the development of power sources that address the physical requirements of these electronic devices, such as flexibility and a small footprint. In ... -
Fast and Sensitive Detection of Bacteria by Means of AC Electrokinetics and Micro-Raman Spectroscopy
(2015-12-01)Rapid diagnosis of pathogens requires the ability to detect the presence of a target pathogen in a sample at as low concentrations as possible. In the present thesis, a surface-based method that can provide early and ... -
Flame Assisted Chemical Vapor Deposition of Photocatalytic Titanium Dioxide Coating on Aluminium Fin Stock
(2013-08-06)Unavailable -
FRAP Measurements of Solute Diffusion Through Hydrogels
(2014-11-04)The distribution of therapeutic agents such as proteins or drug-loaded nanoparticles within a hydrogel following release influences their rate of absorption at the desired site of action. For formulation design purposes, ... -
Free Radical Copolymerization of Hydroxy-Functional Monomers: Kinetic and Semibatch Studies
(2013-02-27)Acrylic resins used as polymeric binders in automotive coatings are complex copolymers containing reactive functional (often hydroxyl) groups. A better understanding of the copolymerization kinetics of these monomers is ... -
Free Radical Polymerization studies of vinyl ester monomers using Pulsed-Lased Polymerization with Size Exclusion Chromatography (PLP-SEC)
(2015-12-02)Polyvinyl acetate and other polyvinyl esters, and their copolymers are used in coatings, adhesives and plastics, and hence fundamental understanding of the mechanisms and polymerization kinetics is vital for process ... -
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 ... -
Functional Chemometrics: Automated Spectral Smoothing with Spatially Adaptive Splines
(2012-10-02)Functional data analysis (FDA) is a demonstrably effective, practical, and powerful method of data analysis, yet it remains virtually unheard of outside of academic circles and has almost no exposure to industry. FDA adds ... -
Functional Nitroxyls for Polypropylene Modification
Chemistry for introducing a long-chain branch (LCB) architecture to linear, isotactic polypropylene (PP) is described, wherein degradation of the polymer matrix through β-scission of macroradicals is inhibited by an additive ... -
Functional Nitroxyls in Polypropylene Based Thermoplastic Vulcanizates
Peroxide vulcanization of polypropylene (PP) based thermoplastic vulcanizates (TPVs) is hindered by PP’s susceptibility to radical degradation. PP degradation occurs through chain scission of tertiary alkyl macroradicals, ... -
Functionalized-Nitroxyls for Use in Peroxide-Initiated Modifications of Polymers
(2014-09-17)Delayed-onset crosslinking of commodity polymers is accomplished by peroxide-initiated reactions of 4-acryloyloxy-2,2,6,6,-tetramethylpiperidine-N-oxyl (AOTEMPO) under solvent-free conditions. Consistent with previous ... -
Geometric Aspects of Interconnection and Damping Assignment - Passivity-Based Control
(2011-02-01)This dissertation deals with smooth feedback stabilization of control-affine systems via Interconnection and Damping Assignment - Passivity-Based Control (IDA-PBC). The IDA-PBC methodology is a feedback control design ... -
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 ... -
High Cell Density Culivation of Methylosinus Trichosporium OB3b
(2008-09-04)Methylosinus trichosporium OB3b is a wild type, obligate methanotroph that grows only on one-carbon compounds and, in the absence of copper, produces high levels of soluble methane monooxygenase (sMMO) to metabolize methane ... -
Hydrogen bonding in radical copolymerization: A kinetic investigation under industrially relevant conditions
Radical solution polymerization is a common method to produce a variety of plastics and coatings. Particularly in the automotive industry, large scale semi-batch operations are used to (co)polymerize monomers of the styrenic, ... -
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 ... -
