Material and Surface Properties of Bio-inspired Polydopamine and its Modified Polypyrrole Functional Nanocomposites
(University of Waterloo, 2015-07-24)Inspired by marine mussel adhesives, the dopamine (DA) polymerization process has been introduced as a versatile deposition method to coat almost all kinds of material surfaces and form a nanoscale polydopamine (PDA) thin ... -
Material Design and Electrochemical Behavior Study on Metal-Based Electrocatalysts for Rechargeable Zn-Air Batteries
(University of Waterloo, 2020-09-02)Zn-based electrochemistries can provide bivalent redox, reserve abundancy in earth, moderate reactivity, and compatibility with aqueous electrolyte. When comparing to Li-based battery technologies, their superiorities in ... -
Material Design and Engineering for Polymer Electrolyte Membrane Zinc-Air Batteries
(University of Waterloo, 2018-03-23)Zinc-air batteries, whose advantages include relatively high energy density (1218 Wh kg-1), abundance of zinc in earth’s crust, and very safe operational characteristics, are promising for applications in consumer electronics, ... -
Material Modelling for Structural Analysis of Polyethylene
(University of Waterloo, 2007-01-17)The purpose of this work was to develop a practical method for constitutive modelling of polyethylene, based on a phenomenological approach, which can be applied for structural analysis. Polyethylene (PE) is increasingly ... -
Material-Induced Platelet and Leukocyte Activation: A Systems Approach
(University of Waterloo, 2014-08-19)A systems approach in the study of blood-biomaterial interactions (BBI) is likely to provide better insight into the transient behaviors of complex biological systems. Although some attempts have been made to apply a systems ... -
Materializing the Hidden Identity of Hong Kong: Re-connecting Hong Kong's vanishing fishing community through urban interventions on the Tam Gong Festival route in Shau Kei Wan
(University of Waterloo, 2023-08-25)Against the backdrop of the expanding metropolis of Hong Kong, many functioning members of contemporary society have concealed facets of themselves that they now deem irrelevant to their daily lives. Over the last half a ... -
Materials physics of half-metallic magnetic oxide films by Pulsed Laser Deposition: Controlling the crystal structure and near-surface properties of Sr2FeMoO6 and CrO2 films
(University of Waterloo, 2009-01-23)The idea of half-metallic ferromagnets was first introduced by de Groot et al. in 1983 based on their calculations. The density of state at the Fermi level for half-metallic ferromagnet is completely polarized, meaning ... -
Maternal Adaptations and Lipid Mobilization During Pregnancy in Rats
(University of Waterloo, 2017-10-31)Docosahexaenoic acid (DHA) is a major structural fatty acid in brain and is required for fetal growth and development. DHA in maternal plasma increases during pregnancy to meet the placental transport demands of the fetus. ... -
The Maternal Health Literacy of South Asian Newcomer Mothers and Canadian-born Mothers
(University of Waterloo, 2024-01-09)Research suggests newcomer mothers score lower than Canadian-born mothers on health literacy (HL) and health numeracy (HN) assessments and have difficulty accessing maternal health services. This dissertation explored the ... -
Math and the Fountain of Youth
(University of Waterloo, 2020-12-10)Ageing is associated with impairments in a number of regulatory processes, including in energy dysregulation that affects multiple metabolic pathways and in the circadian rhythms. In the management of metabolic stress ... -
Math Information Retrieval using a Text Search Engine
(University of Waterloo, 2018-05-18)Combining text and mathematics when searching in a corpus with extensive mathematical notation remains an open problem. Recent results for math information retrieval systems on the math and text retrieval task at NTCIR-12, ... -
MathBrush web application: Design and implementation of an online pen-input interface for computer algebra systems
(University of Waterloo, 2017-08-15)Several pen-math systems have been developed for mobile and tablet platforms, most notably by the MathBrush project. With the increasing variety of available devices and platforms used by students, this thesis aims to ... -
Mathematical Actualism: An Alternative Realist Philosophy of Mathematics
(University of Waterloo, 2022-09-23)The present thesis argues for a philosophy of mathematics, herein dubbed Actualism, which is contrasted with several existing views on the philosophy of mathematics. It begins with a brief introduction to the classical ... -
Mathematical and Statistical Investigation of Steamflooding in Naturally Fractured Carbonate Heavy Oil Reservoirs
(University of Waterloo, 2013-04-23)A significant amount of Viscous Oil (e.g., heavy oil, extra heavy oil, and bitumen) is trapped in Naturally Fractured Carbonate Reservoirs also known as NFCRs. The word VO endowment in NFCRs is estimated at ~ 2 Trillion ... -
Mathematical approaches to the study of cellular heterogeneity, treatment design, and immune response in cancer
(University of Waterloo, 2020-01-09)One of the complicating factors in treating cancer patients is the different levels of heterogeneity involved. In this thesis, we use a combination of mathematical methods (in silico experiments) and experimental data (in ... -
Mathematical Aspects of Scalar-Tensor Field Theories
(University of Waterloo, 2016-09-27)This thesis is based on a study of Lagrange scalar densities which are, in general, concomitants of the metric tensor gij (and its first and second derivatives) together with a scalar field ∅ (and its first derivative). ... -
