Molecular Dynamics Studies of Lipid Monolayer and Bilayer Systems
(University of Waterloo, 2016-08-02)Lipids are a crucial ingredient of biomembranes in cells, and they play a pivotal role in many chemical and biological processes. Lipid based structures, such as lipid monolayers and lipid bilayers, both natural and ... -
Molecular Imprinting with Functional DNA and Nanozymes: Affinity Improvement and Selective Catalysis
(University of Waterloo, 2019-08-19)Molecular imprinting refers to polymerization of functional monomers in the presence of a template molecule. It is a general method to prepare stable and cost-effective artificial ligands as antibody mimics (also known as ... -
Molecular Mechanism of Starch Digestion by Family 31 Glycoside Hydrolases: Structural Characterization and Inhibition Studies of C-terminal Maltase Glycoamylase and Sucrase Isomaltase
(University of Waterloo, 2014-04-22)Although carbohydrates are a principal component of the human diet, the mechanism of the final stages of starch digestion is not fully understood. One approach to treating metabolic diseases such as type II diabetes, ... -
Molecular methods for evaluating the human microbiome
(University of Waterloo, 2014-01-28)In human microbiome analysis, sequencing of bacterial 16S rRNA genes has revealed a role for the gut microbiota in maintaining health and contributing to various pathologies. Novel community analysis techniques must be ... -
Molecular movies and geometry reconstruction using Coulomb explosion imaging
(University of Waterloo, 2017-08-24)Coulomb explosion imaging is a technique of imaging the structure of small molecules in the gas phase and their ultrafast dynamics by inducing the rapid ionization and dissociation of the molecule into its constituent ... -
Molecular Nanomagnets for Novel Spintronics Devices
(University of Waterloo, 2016-01-08)Molecular nanomagnets possess interesting quantum properties that make them potential candidates for qubits in quantum information processing. Heterometallic antiferromagnetic wheels specifically have been shown to have a ... -
Molecular Phylogeography and Species Discrimination of Freshwater <em>Cladophora</em> (Cladophorales, Chlorophyta) in North America
(University of Waterloo, 2006)<em>Cladophora</em> is a widespread freshwater filamentous cholorophyte genus and is frequently observed in eutrophic waters where it can produce large nuisance blooms. These blooms can have direct impacts on water ... -
Molecularly Imprinted Polymers with DNA Aptamer Fragments as Macromonomers
(American Chemical Society, 2016-03-16)Molecularly imprinted polymers (MIPs) are produced in the presence of a template molecule. After removing the template, the cavity can selectively rebind the template. MIPs are attractive functional materials with a low ... -
Monitoring a Shallow Gasoline Release using GPR at CFB Borden
(University of Waterloo, 2011-10-04)This hydrogeophysical field experiment evaluated the ability of high frequency (450 & 900 MHz) ground penetrating radar (GPR) to characterize the release of gasoline over an annual cycle of in situ conditions. In August ... -
