(University of Waterloo, 2014-05-23)Daptomycin (Dap) is a cyclic lipodepsipeptide antibiotic that is currently used in the treatment of bacterial infections caused by Staphylococcus aureus including the strains that are methicillin-resistant (MRSA), as well ... -
Photocatalytic Degradation of Microcystins by TiO2 Using UV-LED Controlled Periodic Illumination
(Multidisciplinary Digital Publishing Institute, 2019-02-14)Toxic microcystins (MCs) produced by freshwater cyanobacteria such as Microcystis aeruginosa are of concern because of their negative health and economic impacts globally. An advanced oxidation process using UV/TiO2 offers ... -
Photocatalytic performances of ZnO nanoparticle film and vertically aligned nanorods in chamber-based microfluidic reactors: Reaction kinetics and flow effects
(Elsevier BV, 2017-07-15)The nanoparticle seed layer (a film) and vertically aligned nanorods of zinc oxide (ZnO) with different lengths were fabricated within a novel chamber-based microfluidic (microchamber) reactor with a varying height of ... -
Photoinduced Toxicity of Metals and PAHs to Hyalella azteca: UV-Mediated Toxicity and the Effects of Their Photoproducts
(University of Waterloo, 2009-05-08)Polycyclic aromatic hydrocarbons (PAH) are a class of common environmental contaminants known to be phototoxic. PAH Photoinduced toxicity is caused by two mechanisms: photomodification and photosensitization. The ... -
Photon Rings and Shadow Size for General Integrable Spacetimes
(University of Waterloo, 2023-08-08)According to the no-hair theorem, the unique characteristics of astrophysical black holes are their masses and spins. However, recent observations from the Event Horizon Telescope (EHT) images of M87 and Sgr A* have ... -
Photonic Three-Level Systems Within the Framework of Generalised Probabilistic Theories
(University of Waterloo, 2021-09-24)If one seeks to test quantum theory not against a particular alternative but against many alternatives in a landscape of possibilities, it is crucial to be able to analyze experimental data in a theory-agnostic way. This ... -
Photons & Phonons: A room-temperature diamond quantum memory
(University of Waterloo, 2016-08-19)This thesis presents demonstrations of the storage and manipulation of single photons in a room-temperature diamond quantum memory using a Raman memory protocol. We report on results from four experiments. In the first ... -
Photophysical and Optoelectronic Properties of Pristine, Doped and Surface-Functionalized Two-Dimensional Zinc Oxide Nanostructures
(University of Waterloo, 2016-01-20)As one of the most studied transparent conducting oxides, zinc oxide (ZnO) has received a lot of attention due to its physical, chemical, optical and optoelectronic properties. The present study focusses on the photophysical ... -
Photosphere Tour Guide
(University of Waterloo, 2021-08-20)This document serves as a comprehensive guide for creating and implementing Virtual Reality (VR) into education at the post-secondary level, as well as recommendations for integrating course learning objectives in Virtual ... -
Physical and biogeochemical gradients and exchange processes in Nyanza Gulf and main Lake Victoria (East Africa)
(University of Waterloo, 2009-01-22)Nyanza Gulf is a large, shallow and long river-influenced embayment located in northeastern Lake Victoria. The gulf opens to the main lake through the narrow and deep Rusinga Channel, the exchange zone between the two ... -
Physical and Geochemical Characterization of Two Wetlands in the Experimental Lakes Area, North-western Ontario, Canada
(University of Waterloo, 2012-09-27)Anthropogenic disruptions in the form of hydrological alterations, such as dam construction and the associated water diversions are a cause of much upheaval to local and regional ecosystems. Lake 626 within the Experimental ... -
Physical Hydrogeology and Impact of Urbanization at the Waterloo West Side: A Groundwater Modelling Approach
