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 ... -
Laser-cooled Atomic Ensembles in Hollow Optical Fibers
(University of Waterloo, 2021-05-06)This thesis explores hollow-core fibres as a platform for quantum optics experiments with laser-cooled atomic ensembles. The non-diffracting, tightly-confined guided modes of these fibers grant us a ~µm-wide one-dimensional ... -
Laser-initiated Coulomb explosion imaging of small molecules
(University of Waterloo, 2008-09-02)Momentum vectors of fragment ions produced by the Coulomb explosion of CO2z+ (z = 3 - 6) and CS2z+ (z = 3 - 13) in an intense laser field (~50 fs, 1 x 1015 W/cm2) are determined by the triple coincidence imaging technique. ... -
LASS-ICP-MS collection of trace element and 87Sr/86Sr isotope data using a novel uneven distribution of sample material for otolith microchemistry
(University of Waterloo, 2022-01-26)Understanding the behaviour and movement of fish populations is crucial to developing plans to properly manage fisheries, and to predict effects of ongoing environmental change. In northern regions, physically tracking ... -
The Late Proterozoic to Palaeozoic Tectonic Evolution of the Long Range Mountains in Southwestern Newfoundland
(University of Waterloo, 2007-04-04)Ever since the first plate-tectonic model for the Appalachians was proposed, the Laurentian margin has been interpreted as having experienced a collision-related dynamo-thermal event during the Middle Ordovician Taconic ... -
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 ... -
Laurentide Ice Sheet dynamics evolution in the inner-ice sheet region of northeastern Quebec, Canada
(University of Waterloo, 2020-05-06)The study of past ice sheets, such as the Laurentide Ice Sheet (LIS), which covered most of northern North America during the last glaciation (last ~100-kyr), provides critical knowledge about the long-term behaviour of ... -
Learning about Ontario's Paleozoic Geology with Virtual Reality Google Expedition Tours
(2020-02)How well can you interpret or place into context the different geological features or rock types that are exposed along roadways, rivers, coastlines or construction sites? Here in the Department of Earth and Environmental ... -
A Least-Cost Strategy for Evaluating a Brownfields Redevelopment Project Subject to Indoor Air Exposure Regulations
(University of Waterloo, 2012-08-31)Over the course of the past several decades the benefits of redeveloping brownfields have been widely recognized. Actions have been taken to foster sustainable redevelopment of brownfields by government, policy makers and ... -
Life history and population dynamics of Eastern Sand Darter (Ammocrypta pellucida) in the lower Thames River, Ontario
(University of Waterloo, 2009-06-17)Eastern Sand Darter (Ammocrypta pellucida) is listed as Threatened under the Canadian Species at Risk Act. Canadian populations are declining primarily due to the siltation of sandy depositional areas, the preferred habitat ... -
Life history characteristics of Lake Whitefish (Coregonus clupeaformis), Cisco (Coregonus artedi), and Northern Pike (Esox lucius) in rivers of the Hudson Bay Lowlands
(University of Waterloo, 2017-05-15)Many northern fishes display plasticity in life history and trophic ecology that can influence productivity of fisheries and bioaccumulation of contaminants, such as mercury. Cisco (Coregonus artedi), Lake Whitefish ... -
Life History of Dwarf Longnose Sucker (Catostomus catostomus) in the Elk River Watershed
(University of Waterloo, 2014-05-01)In 2004, a population of dwarf longnose sucker was discovered co-existing with the normal form within the Elk River Watershed of south-eastern British Columbia. This thesis evaluated morphological, genetic and life history ... -
Ligand Specificity and Affinity in the Sulforhodamine B Binding RNA Aptamer
(Elsevier Inc., 2020-07-18)Binding affinity and selectivity are critical properties of aptamers that must be optimized for any application. The sulforhodamine B binding RNA aptamer (SRB‐2) is a somewhat promiscuous aptamer that can bind ligands ... -
LIGAND TRANSFER REACTIONS OF HYPERVALENT IODINE REAGENTS WITH PHOSPHORUS COMPOUNDS
(University of Waterloo, 2018-01-23)Many hypervalent iodine compounds are used as versatile reagents in synthetic organic chemistry. Hypervalent iodine reagents are capable of oxidizing trivalent phosphorus compounds into pentavalent, by transferring their ... -
Light-Activated Metal-Coordinated Supramolecular Complexes with Charge-Directed Self-Assembly
(American Chemical Society, 2013-02-21)Metal-coordinated materials are attractive for many applications including catalysis, sensing, and controlled release. Adenine and its derivatives have been widely used to generate many coordination complexes, polymers, ... -
Line-Field Spectral Domain Optical Coherence Tomography: Design and Biomedical Applications
(University of Waterloo, 2024-05-10)Corneal diseases such as keratoconus and Fuchs' dystrophy lead to the dysfunction of the cornea, which can result in vision loss. Early-stage detection at the cellular level provides the opportunity for treatment that slows ... -
Line-Scan Spectral-Domain Optical Coherence Tomography for Cellular Resolution Structural and Vascular Imaging of Biological Tissues
(University of Waterloo, 2022-06-07)Optical coherence tomography (OCT) is an optical interferometric technique for non-invasive contactless imaging of the cellular-level structures of biological tissues. However, the application of OCT for in-vivo volumetric ... -
Linking soil moisture content and carbon dioxide fluxes: From batch experiments to process-based modelling
(University of Waterloo, 2020-02-19)The emissions of carbon dioxide (CO2) from soil to the atmosphere represent a major flux within the global carbon cycle. Soil CO2 fluxes depend on environmental factors including soil moisture and oxygen, and on intrinsic ... -
