Towards On-demand Generation of Entangled Photons with Quantum Dots
(University of Waterloo, 2020-01-17)The biexciton-exciton cascade in quantum dots (QDs) yields entangled photon pairs, and recent developments in engineering photonic structures around the dot for efficient light extraction and proper control of the ... -
Towards point-of-care detection of polymicrobial infections: Rapid colorimetric response using a portable spectrophotometer
(Elsevier, 2016-09)Infectious diseases spread rapidly because current diagnostic methods are slow, expensive, and require technical expertise. Biosensors have recently been used as devices that can be deployed at the point-of-care for rapid ... -
Towards Practical Hybrid Quantum / Classical Computing
(University of Waterloo, 2020-09-28)Quantum computing is in a critical phase where theoretical schemes and protocols are now being implemented in the real world for the first time. Experimental implementations can help us solidify ideas, and can also complicate ... -
Towards Quantifying Groundwater Resources of the Paloluoma Buried Bedrock Valley in Western Finland with Groundwater Modelling
(University of Waterloo, 2022-05-03)Groundwater provides about 60 percent of drinking water in Finland. In western Finland, drinking water for the town of Kurikka (pop. ~21 700) comes from glaciofluvial aquifers confined underneath thick glaciomarine aquitards ... -
Towards Real-World Adoption of Quantum Key Distribution using Entangled Photons
(University of Waterloo, 2012-08-21)In order for quantum key distribution (QKD) to move from the lab to widespread adoption, it will need to be compatible with existing infrastructure. To that end, I demonstrate an implementation of QKD with entangled ... -
Towards simulating 2D effects in lattice gauge theories on a quantum computer
(University of Waterloo, 2020-10-26)Quantum Field Theories (QFTs) are the most successful theories for describing nature at its most fundamental level. Despite the fact that QFTs are capable of predicting a wide range of phenomena, obtaining solutions to ... -
Towards the Development of Thermoresponsive Starch Films
(University of Waterloo, 2018-05-22)Wound dressings are an important part of the global wound care market. In addition to having desirable physical properties such as flexibility and gas permeability, it is also important that they be easily removed. As ... -
Towards the Production of the Haemophilus influenzae IgA1 protease in Escherichia coli
(University of Waterloo, 2014-12-12)H. influenzae is a gram-negative bacterium colonizing the human respiratory tract and is responsible for hundreds of thousands of deaths annually. To aid in persistence and infection in its human host H. influenzae produces ... -
Towards understanding of poly-guanine activated fluorescent silver nanoclusters
(Institute of Physics, 2014-03-18)It has been recently reported that the fluorescence of some DNA-templated silver nanoclusters (AgNCs) can be significantly enhanced upon by hybridizing with a partially complementary DNA containing a G-rich overhang near ... -
Towards vertex renormalization in 4d Spin Foams
(University of Waterloo, 2017-07-24)A long-standing open problem in 4-dimensional Spin Foam models of Quantum Gravity has been the behavior of the amplitudes under coarse graining. In this thesis, we attempt to study this question by using the recent ... -
Toxicity and bioaccumulation kinetics of cadmium and potassium permanganate in two clades within the 𝘏𝘺𝘢𝘭𝘦𝘭𝘭𝘢 𝘢𝘻𝘵𝘦𝘤𝘢 species complex
(University of Waterloo, 2019-09-12)The freshwater amphipod 𝘏𝘺𝘢𝘭𝘦𝘭𝘭𝘢 𝘢𝘻𝘵𝘦𝘤𝘢 has been frequently used in toxicology since the 1980s due to its general sensitivity, ease of culture, and North America-wide geographic range. Over the past 20 years, ... -
Toxicity Assessment of Oil Sands Process-Affected Water Using Fish Cell Lines
(University of Waterloo, 2010-09-28)Toxicity assessment of large numbers of oil sands process-affected waters (OSPW) are needed in order to reclaim mined oil sands aquatic reclamation scenarios, such as End Pit Lakes (EPLs). Conventional toxicity testing ... -
Toxicity Assessment of PAHs and Metals to Bacteria and the Roles of Soil Bacteria in Phytoremediation of Petroleum Hydrocarbons
(University of Waterloo, 2008-09-26)Petroleum hydrocarbons (PHCs) are a class of ubiquitous contaminants in the environment. PHCs impact to soil and water occur at well sites, refineries, service stations, and other facilities. Petroleum processing and ... -
Toxicity of Ophthalmic Solutions, Benzalkonium Chloride and UV Radiation on Human Corneal Epithelial Cells in vitro
(University of Waterloo, 2015-06-12)The purpose of this work was to develop a sensitive in vitro method for ocular toxicity testing; and to use this method to assess the individual and combined effects of ophthalmic solutions, benzalkonium chloride (BAK), ... -
Trace elements at the intersection of marine biological and geochemical evolution
(Elsevier, 2016-12-01)Life requires a wide variety of bioessential trace elements to act as structural components and reactive centers in metalloenzymes. These requirements differ between organisms and have evolved over geological time, likely ... -
Tracing galaxy evolution through the reconstruction of their star formation histories
(University of Waterloo, 2023-05-24)This thesis studies the star formation histories (SFHs) of galaxies in order to understand the nature of 'quenching.' The suppression of star formation, i.e., quenching, over the history of the Universe results in a growing ... -
The Tracing of a Contaminant (Tritium) from Candu Sources: Lake Ontario
(University of Waterloo, 1997)In any research program we begin with a hypothesis and when our expected results do not concur with the observed results we must try and understand the dynamics behind the changed process. In this study we were trying ... -
