Marine redox conditions during deposition of Late Ordovician and Early Silurian organic-rich mudrocks in the Siljan ring district, central Sweden
(Elsevier, 2017-05-10)The Late Ordovician Period witnessed the second largest mass extinction in the Phanerozoic Eon and the Hirnantian glaciation. To infer ocean redox conditions across the Ordovician-Silurian transition, we measured the U (as ... -
Mass-Selected Infrared Multiple-Photon Dissociation as a Structural Probe of Gaseous Ion-Molecule Complexes
(University of Waterloo, 2009-08-31)Mass-selected infrared multiple photon spectroscopy (IRMPD), Fourier transform ion cyclotron resonance (FT-ICR) kinetic experiments, RRKM and electronic structure calculations have been performed in order to propose a ... -
Materials physics of half-metallic magnetic oxide films by Pulsed Laser Deposition: Controlling the crystal structure and near-surface properties of Sr2FeMoO6 and CrO2 films
(University of Waterloo, 2009-01-23)The idea of half-metallic ferromagnets was first introduced by de Groot et al. in 1983 based on their calculations. The density of state at the Fermi level for half-metallic ferromagnet is completely polarized, meaning ... -
Mathematical and Statistical Investigation of Steamflooding in Naturally Fractured Carbonate Heavy Oil Reservoirs
(University of Waterloo, 2013-04-23)A significant amount of Viscous Oil (e.g., heavy oil, extra heavy oil, and bitumen) is trapped in Naturally Fractured Carbonate Reservoirs also known as NFCRs. The word VO endowment in NFCRs is estimated at ~ 2 Trillion ... -
Matrix compatible solid phase microextraction coating, a greener approach to sample preparation in vegetable matrices
(Elsevier, 2017-09-01)This work proposes the novel PDMS/DVB/PDMS fiber as a greener strategy for analysis by direct immersion solid phase microextraction (SPME) in vegetables. SPME is an established sample preparation approach that has not yet ... -
Maximal cell density predictions for compressible polymer foams
(Elsevier, 2012-12-05)Thermodynamic upper bounds for polymer foam cell densities are predicted using compressible selfconsistent field theory. It is found that the incompressible limit always gives the highest, and therefore ultimate, upper ... -
Mean-Field Theory of Collective Behavior of Quantum Dipolar Rotors
(University of Waterloo, 2021-02-08)Motivated by the recent experimental measurements of the dielectric property of confined quantum dipolar molecules, the orientational dipolar ordering transition is investigated in the quantum generalization of the quantum ... -
THE MEASUREMENT OF INTER-PARTICLE DIFFUSION COEFFICIENTS IN MINE WASTES
(University of Waterloo, 2021-05-04)Acid mine drainage (AMD) is the release of acidic waters from mines, waste-rock piles and mine tailings impoundments containing high concentrations of SO4, Fe(II) and other metal(oid)s. The bulk of AMD generation occurs ... -
Measurement of Surface Tensions in Aggregated Cells of the Embryonic Chick
(University of Waterloo, 2008-01-23)Cell surface properties are crucial to the mechanisms by which groups of cells organize themselves during embryogenesis, cancer metastases and tissue engineering. Measured surface tension values provide a quantitative ... -
Measurement of Tensile Forces in Xenopus laevis Neural Tissue
(University of Waterloo, 2010-01-22)Neurulation is critical for the proper development of the central nervous system during embryogenesis. This process requires coordinated morphogenetic movements driven by localized cell movements. The key morphogenetic ... -
Measuring Entanglement Entropy in Valence Bond Quantum Monte Carlo Simulations
(University of Waterloo, 2010-12-08)In this thesis we examine methods for measuring entanglement entropy in spin-1/2 Heisenberg systems using quantum Monte Carlo in the valence bond basis. We begin by presenting the quantum Monte Carlo techniques used in ... -
Measuring Non-Markovianity of Noise in the Cenrtal Spin System
(University of Waterloo, 2019-05-24)In this thesis, we explore non-Markovian noise in the central spin system due to the coupling between the central spin and the environment. We use a solid state nuclear magnetic resonance system to do the experiment since ... -
Measuring Quantum Correlations of Polarization, Spatial Mode, and Energy-Time Entangled Photon Pairs.
(University of Waterloo, 2023-09-07)Optical quantum technologies have found applications in all facets of quantum information. Single photons are actively being researched for quantum computation, communication, and sensing, due to their robustness against ... -
Measuring the Environmental Dependence of Galaxy Haloes with Weak Lensing
(University of Waterloo, 2013-09-04)We investigate the uses of gravitational lensing for analysing the dark matter haloes around galaxies, comparing galaxies within groups and clusters to those in the field. We consider two cases: when only photometric ... -
Measuring Trapped Ion Qudits
(University of Waterloo, 2019-09-26)Quantum information has typically focused on using 2-level qubits to perform simulation and computation. We propose to expand the number of levels for computation using qudits, where \(d>2\). Doing so could be a viable ... -
Mechanisms controlling the recycling of nutrient silicon in freshwater sediments: An experimental study of the interactions between silicon, iron and phosphorus
(University of Waterloo, 2020-12-23)Dissolved silicon (DSi) is an essential nutrient for numerous terrestrial and aquatic organisms. In freshwater systems, including streams, rivers and lakes, an important class of siliceous algae are diatoms. Human activities, ... -
