Biogeochemical cycling of nutrient silicon in a human-impacted large lake nearshore environment (Hamilton Harbour Area of Concern, Lake Ontario, Canada)
(University of Waterloo, 2017-12-14)The biogeochemical cycling of nutrient silicon (Si) through rivers, wetlands, lakes, and artificial reservoirs regulates the magnitude and bioavailability of Si delivered downstream and to the ocean (Frings et al. 2014; ... -
Design and Characterization of an 8x8 Lateral Detector Array for Digital X-Ray Imaging
(University of Waterloo, 2011-02-01)X-ray imaging has become one of the most pervasive and effective means of diagnosis in medical clinics today. As more imaging systems transition to digital modes of capture and storage, new applications of x-ray imaging, ... -
Grating Technology and System Development for High-Resolution X-Ray Phase-Contrast Imaging
(University of Waterloo, 2023-02-16)X-ray imaging is a workhorse of medical imaging, and in particular, high-resolution X-ray imaging is used in the detection of carcinomas and micro-calcifications in the breast, small fractures, and early stages of cancerous ... -
Influence of a dammed reservoir on nutrient (N, P, Si) loads and ratios of the Thames River, Ontario
(University of Waterloo, 2021-01-20)The increasing frequency and severity of harmful algal blooms (HABs) in Lake Erie have been troubling developments in the past few decades. Excess loads of phosphorus (P) from the watershed are considered to be a primary ... -
Neutron interferometer crystallographic imperfections and gravitationally induced quantum interference measurements
(American Physical Society, 2017-01-25)Dynamical diffraction leads to an interesting, unavoidable set of interference effects for neutron interferometers. This experiment studies the interference signal from two and three successive Bragg diffractions in the ... -
Novel Nano-Structured Silicon and Co3O4 Materials as Anode for High-Performance Lithium Ion Batteries
(University of Waterloo, 2014-04-29)Lithium ion batteries (LIBs) play an essential role in modern life. Although relatively unknown throughout past decades, LIBs have supplanted several categories of chemically rechargeable batteries including lead-acid, ... -
Perturbations to nutrient and carbon cycles by river damming
(University of Waterloo, 2017-06-30)The damming of rivers represents one of the most far-reaching human modifications to the flows of water and associated matter from land to sea. Globally there are over 70 000 large dams whose reservoirs store more than ... -
Spherical Silicon Photovoltaics: Material Characterization and Novel Device Structure
(University of Waterloo, 2008-08-28)Single crystalline silicon spheres have been used as alternative material for solar cell fabrication. This innovative technology has several advantages over traditional wafer technology. However, the material, process ... -
Ultra Low Dissipation Silicon Nanowire Resonator Arrays for Scanning Probe Applications
(University of Waterloo, 2020-01-23)This work describes the fabrication and characterization of silicon nanowire oscillators for use in ultra-high sensitivity force detection. These structures are optimized for use as scanning probes by fabricating ...
