Development and characterization of stimuli-responsive drug delivery systems to prevent HIV infection and the treatment of chronic wounds
(University of Waterloo, 2021-06-10)Patient compliance is very important and highly depends on the drug dosage form which correlates with the success of therapy. Drug delivery systems can be adapted to different pharmaceutical ingredients and to different ... -
Development of a Microfluidic Hemodialysis Device Equipped with an Antifouling Nanoporous Dialysis Membrane
(University of Waterloo, 2021-06-08)This thesis presents a microfluidic hemodialyzer and an experimental platform and demonstrates that the performance of a polycarbonate membrane used in a continuous setting that can be comparable to commercial hollow-fibre ... -
Late-universe signals in the microwave sky: extragalactic dust, electrons, and other baryonic effects
(University of Waterloo, 2021-06-07)This thesis collects much of the work I have done over the last four years as a PhD student. It has two focuses. Part 1 discusses gravitational radiation emitted from two maximally charged black holes in Einstein--Maxwell--dilaton ... -
Optimizing protein S-acylation detection in autophagy
(University of Waterloo, 2021-06-04)S-acylation, sometimes referred to as S-palmitoylation or simply palmitoylation, is a posttranslational protein modification involving the covalent addition of a fatty acid to cysteine residues. Since the first characterization ... -
Laser-Based Imaging of Novel Charge Density Wave and Superconducting Materials
(University of Waterloo, 2021-06-02)The following thesis presents experimental study of two crystalline materials which show correlated electron phases. The first material 1T-TaS2 is a two-dimensional van-der-Waals material. This family of materials ... -
Magnetotransport in Transition Metal Dichalcogenide Semimetals
(University of Waterloo, 2021-06-02)In this thesis, we study the large magnetoresistance in MoTe2, and non-linear anomalous Hall effect in MoTe2 and WTe2. Thin flakes cleaved from layered single crystals exhibit high mobility, and semimetals show nearly ... -
The use of stable isotopes to assess the controls on pelagic carbon basal resources in Canadian Shield lakes
(University of Waterloo, 2021-06-02)Freshwater lakes are often natural sources of greenhouse gases (GHGs) such as carbon dioxide (CO₂) and methane (CH₄) to the atmosphere, and therefore it is important to examine carbon and nutrient cycling in these complex ... -
Remote Paleohydrograph Reconstruction of the Stockton Island Tombolo
(University of Waterloo, 2021-05-01)Rising lake levels have become a concern for the coasts of Lake Superior and one such coastline is the Stockton Island Tombolo (SIT) that protects the Pine Barrens Habitat (PBH) in the Apostle Islands National Lakeshore ... -
Comparing Paleohydrograph Reconstructions from Subsurface Stratigraphy and Topography at the Sault Ste. Marie Strandplain
(University of Waterloo, 2021-05-01)The Great Lakes are currently at high water levels, which are negatively impacting coastal infrastructure, coastal ecosystems, and stakeholders that rely on the lakes. To better understand natural fluctuations, which ... -
Developing Virtual Field Experiences to Promote Student Learning and Bridge Knowledge Gaps between the Classroom and the Field
(University of Waterloo, 2021-05-01)In 2020, a specific type of Virtual Reality (VR), Virtual Field Experiences (VFE), was identified as a proof-of-concept for positively contributing to student learning by the University of Waterloo's Department of Earth ... -
Impactus Finiens Orbem Terrarum: An Updated Risk Assessment of World Ending Asteroid Impacts
(University of Waterloo, 2011-12-01)As technology develops, the rate of discovering and observing space tends to relatively increase. Our understanding of how the Universe works, and how the planets interact with one another make us weary of what is to come. ... -
The Physical Mechanisms of Microbiological Cellular Transport, Storage, and Metabolism of Aromatic Hydrocarbon-Degrading Soil Microbiota
(University of Waterloo, 2021-06-01)The Monod bioreaction equation, though justified from extensive practical use, has been found to have limited mechanistic basis (Enouy, Walton, et al., 2021). To attempt to gain a biological mechanistic representation of ... -
Gravitational Thermodynamics: From Black Holes to Holography
(University of Waterloo, 2021-06-01)The subject of gravitational thermodynamics lies at the center of numerous fields of study, many of which may seem disconnected, yet have proven to be deeply entwined. This thesis examines two primary facets of this subject, ... -
Identification and characterization of toxic cyanobacteria in two forested maritime watersheds in North America
(University of Waterloo, 2021-06-01)Healthy forested watersheds naturally provide high quality drinking water to communities. However, the integrity and quality of these water sources may be threatened by climate change-exacerbated disturbances such as ... -
Mitigating Agricultural Impacts from Field to Stream: Optimizing Biochar Field Amendments and Novel Denitrifying Bioreactors for Mitigating Greenhouse Gas Emissions
(University of Waterloo, 2021-06-01)Greenhouse gas (GHG) emissions resulting from agricultural activities are a major contributor to total emissions in Canada and around the world. The application of synthetic and animal-manure fertilizers is common practice ... -
