Calibrating the Long-Range Backbone Dynamics of Polymers in Solution Using Two Different Models
(University of Waterloo, 2022-09-29)The fluorescence decays of a series of 41 pyrene-labeled poly(oligo(ethylene glycol)methyl ether methacrylate)s (Py-PEGnMA where n = 0, 1, 2, 3, 4, 5, 9, 16, 19) were prepared by free-radical polymerization of 1-pyrenebutyl ... -
Characterization of the Distribution of Pyrene Molecules in Confined Geometries with the Model Free Analysis
(American Chemical Society, 2017-12-21)Evidence is provided showing that global Model Free Analysis (MFA) of monomer and excimer fluorescence decays of pyrene dissolved in aqueous solutions of sodium dodecyl sulfate (SDS) provides the same structural and dynamic ... -
Evaluating Vadose Zone Moisture Dynamics using Ground-Penetrating Radar
(University of Waterloo, 2012-02-27)Near-surface sediments in the vadose zone play a fundamental role in the hydrologic system. The shallow vadose zone can act as a buffer to delay or attenuate surface contaminants before they reach the water table. It also ... -
Long Range Polymer Chain Dynamics Probed with Pyrene Excimer Fluorescence
(University of Waterloo, 2016-09-27)A series of fluorescently labeled vinyl polymers bearing a C1-C18 side-chain (namely poly(methyl methacrylate), poly(butyl methacrylate), poly(octyl methacrylate), poly(lauryl methacrylate), and poly(stearyl methacrylate) ... -
Satellite Dynamics in Dark Matter Halos
(University of Waterloo, 2010-09-01)I have used an analytic model of tidal interactions to predict the evolution of a substructure in a static dark matter halo. Given the initial conditions of the satellite and background halo, the model predicts with high ... -
Using Pyrene Excimer Fluorescence To Probe the Interactions between Viscosity Index Improvers and Waxes Present in Automotive Oil
(American Chemical Society, 2017-03-28)A new methodology based on pyrene excimer fluorescence (PEF) was applied to quantitatively measure the actual level of intermolecular association between ethylene propylene (EP) copolymers in toluene in the presence of ...
