Interaction of Tear Inflammatory Markers with Contact Lens Materials
(University of Waterloo, 2020-01-28)Biomaterials are natural or synthetic materials that come into contact with biological tissue. Contact lenses are the most commonly used biomaterials, being worn by an estimated 140 million people worldwide. While contact ... -
The interaction of ultraviolet radiation, dissolved organic carbon and primary production by Laurentian Great Lake phytoplankton communities
(University of Waterloo, 2012-01-12)Man-made chemicals are continuing to erode the ozone layer, and recovery of the ozone layer is slow. Therefore aquatic ecosystems are continuing to receive elevated ultraviolet radiation (UVR). The aim of this work was to ... -
Interactions between DNA and starch nanoparticles: adsorption and covalent attachment
(University of Waterloo, 2013-08-07)Biopolymers have been recently received more and more attention as a renewable substitute for traditional petroleum-based materials. Products made from petroleum-based materials typically cannot be recovered, with long ... -
Interactions of Cationic Peptides and Ions with Negatively Charged Lipid Bilayers
(University of Waterloo, 2006)In this thesis we study the interactions of ions and cationic peptides with a negatively charged lipid bilayer in an ionic solution where the electrostatic interactions are screened. <br /><br /> We first examine the ... -
Interactions of ciliates with cells and viruses of fish
(University of Waterloo, 2013-01-29)This thesis develops and utilizes in vitro approaches to study ciliate/fish interactions. The thesis is divided into six chapters. Chapter one reviews the literature on culturing ciliates and fish cells. Chapter two develops ... -
Interactions of Phosphate and Silicate with Iron oxides in Freshwater Environments
(University of Waterloo, 2019-04-29)Internal phosphorus loads, from bottom sediments to surface waters, are often comparable in magnitude to external phosphorus loads, particularly in water bodies with a history of high external phosphorus inputs from point ... -
Interactions, Entanglement, and Anomalies in Topological Semimetals
(University of Waterloo, 2023-08-04)Topology and symmetry have become one of the backbones of modern condensed matter physics. These concepts play a large role in determining the possible effects of interactions and entanglement in both gapped and gapless ... -
An interdisciplinary approach to monitoring the hydroecology of thermokarst lakes in Old Crow Flats, Yukon Territory, Canada
(University of Waterloo, 2012-09-28)Lake-rich thermokarst landscapes, such as Old Crow Flats (OCF) in northern Yukon, Canada have been identified as amongst the most vulnerable to climate change. This has raised concerns of the Vuntut Gwitchin First Nation ... -
Interfacial Properties of Amphiphilic Dendritic Polymers
(University of Waterloo, 2006)The self-assembly behavior of arborescent polystyrene-<em>graft</em>-poly(ethylene oxide) copolymers (PS-<em>g</em>-PEO) at the air-water interface and the solubilization/release properties of arborescent polystyrene-<em ... -
Interfacing fluorescent DNA oligonucleotides with graphene oxide and metal oxides: from adsorption to sensing
(University of Waterloo, 2022-08-18)DNA, apart from being the mode of genomic information storage, has found several uses in catalysis (DNAzymes) and target detection (aptamers). Developing novel biosensors utilizing these properties has therefore been a ... -
Interfacing Liposomes with Metal Ions and Metal Oxides: Coordination Chemistry, Surface Forces and Membrane Integrity
(University of Waterloo, 2020-09-04)Liposomes are self-closed vesicles composed of lipid bilayer walls that have been widely used as models for cell membranes and drug delivery vehicles. One interesting research direction is to study the interactions of ... -
Interfacing Zwitterionic Liposomes with Inorganic Nanomaterials: Surface Forces, Membrane Integrity, and Applications
(American Chemical Society, 2016-05-10)Zwitterionic phosphocholine (PC) lipids are the main constituent of the mammalian cell membrane. PC bilayers are known for their antifouling properties, yet they are adsorbed by all tested inorganic nanoparticles. This ... -
Intermediate and Low Level Nuclear Waste Stabilisation: Carbonation of Cement-based Wasteforms
(University of Waterloo, 2003)Carbonation is a naturally-occurring process whereby Ca-containing cement phases lose their hydration water and are converted to carbonate minerals by reaction with atmospheric CO₂. As these secondary minerals ... -
Internally Contracted Multireference Coupled Cluster Method and Normal-Order-Based Automatic Code Generator
(University of Waterloo, 2009-04-30)Single reference coupled cluster theory has been established as the method of choice for calculating electronic properties of small-to-medium size molecules. However, in typical multireference cases, such as bond breaking ... -
