Exploring the Structures and Properties of Cationic Aromatic Clusters
(University of Waterloo, 2020-12-02)In this thesis, the structures and properties of protonated aromatic clusters have been investigated. The aromaticity of the phenyl ring can be influenced by the substituents. Electron withdrawing groups (EWGs) can reduce ... -
Exploring the thermal stability of DNA-linked gold nanoparticles in ionic liquids and molecular solvents
(Royal Society of Chemistry, 2012-11-01)While water is the most commonly used solvent for DNA, many co-solvents have been added for various applications. Ionic liquids (ILs) are molten salts at around room temperature. ILs have been tested as a green solvent for ... -
Exploring the Ventral Hippocampal Formation
(University of Waterloo, 2014-10-23)The hippocampus (HC) is important for both memory and spatial navigation. These functions are thought to be supported by spatial firing patterns of "place cells" which are active in only certain locations within environments. ... -
Expression Inactivating Mechanisms of Major Histocompatibility Class I Alleles in Melanogrammus aeglefinus
(University of Waterloo, 2010-08-30)Melanogrammus aeglefinus, commonly known as haddock, is a commercially important marine fish species closely related to cod. Preliminary investigations into the immune function of this species has revealed several unique ... -
Expression of photosynthetic genes and possible regulatory mechanisms in the single-cell C4 species, Bienertia sinuspersici
(University of Waterloo, 2012-03-15)Bienertia sinuspersici is one of three terrestrial plants identified to perform C4 photosynthesis in a single chlorenchyma cell by compartmentation of organelles and photosynthetic enzymes. This thesis describes a study ... -
Extended Latanoprost Release from Commercial Contact Lenses: In Vitro Studies Using Corneal Models
(Public Library of Science, 2014-10-09)In this study, we compared, for the first time, the release of a 432 kDa prostaglandin analogue drug, Latanoprost, from commercially available contact lenses using in vitro models with corneal epithelial cells. Conventional ... -
Extended thermodynamics of Taub-NUT and Einstein-scalar spacetimes
(University of Waterloo, 2021-08-12)The main objective of this thesis is to summarize recent developments on the thermodynamics of both AdS Einstein-scalar spacetimes and Lorentzian Taub-NUT spacetimes. We summarize and apply well-known techniques in black ... -
Extensive marine anoxia during the terminal Ediacaran Period
(American Association for the Advancement of Science, 2018-06-20)The terminal Ediacaran Period witnessed the decline of the Ediacara biota (which may have included many stemgroup animals). To test whether oceanic anoxia might have played a role in this evolutionary event, we measured U ... -
Extracellular dsRNA induces a type I interferon response mediated via class A scavenger receptors in a novel Chinook salmon derived spleen cell line
(Elsevier, 2018-12-01)Despite increased global interest in Chinook salmon aquaculture, little is known of their viral immune defenses. This study describes the establishment and characterization of a continuous cell line derived from Chinook ... -
Extraction of DNA staining dyes from DNA using hydrophobic ionic liquids
(Royal Society of Chemistry, 2013-05-18)The partition of oligonucleotides and DNA staining dyes into a few hydrophobic ionic liquids has been studied, where the oligonucleotides remain in the aqueous phase and all the DNA staining dyes are extracted in the ionic ... -
Extraction of Oil from Oil Sands Using Thermoresponsive Polymeric Surfactants
(American Chemical Society, 2015-03-18)Several thermoresponsive block copolymers constituted of a poly(ethylene glycol) (PEG) and a poly(2-(2-methoxyethoxy) ethyl methacrylate) (PMEO(2)MA) block were prepared by atom transfer radical polymerization (ATRP) and ... -
F2:F3b Ratio and BOC-Adjusted PHC F3 Approach to Resolving False Detections of Crude Oil and Diesel Drilling Waste in Clean Soils and Manure Compost
(University of Waterloo, 2013-09-11)The Canadian Council of Ministers of the Environment (CCME) endorsed the Reference Method for the Canada-Wide Standard (CWS) for Petroleum Hydrocarbons (PHC) in Soil – Tier 1 Method in 2001. The purpose of the CWS is to ... -
Fabrication of 3D Hybrid Architectures Composed of sp2-Carbon and Inorganic Materials
(University of Waterloo, 2013-10-15)Three dimensional (3D) hybrid architectures are new types of materials that have a number of technological applications. However, the synthesis of such materials has been problematic to date. The objective of this study ... -
Fabrication of an Atom Chip for Rydberg Atom-Metal Surface Interaction Studies
(University of Waterloo, 2007-09-28)This thesis outlines the fabrication of two atom chips for the study of interactions between ⁸⁷Rb Rydberg atoms and a Au surface. Atom chips yield tightly confined, cold samples of an atomic species by generating magnetic ... -
