Quantifying the Level of Intermacromolecular Interactions in EthylenePropylene Copolymers by Using Pyrene Excimer Formation
(American Chemical Society, 20150714)A unique methodology based on fluorescence measurements is introduced to quantitatively measure the actual level of interpolymeric association between ethylenepropylene (EP) copolymers used as viscosity index improvers ... 
Quantifying the role of reservoirs in altering phosphorus dynamics using a combination of data analysis and process modeling
(University of Waterloo, 20220429)Excess phosphorus (P) from agricultural watersheds promotes eutrophication in downstream aquatic systems. Reservoirs retain P generated from farm fields and protect downstream waters. Reservoirs also act as hotspots for P ... 
Quantitative analysis of biofluid spots by coated blade spray mass spectrometry, a new approach to rapid screening
(Springer Nature, 20171123)This study demonstrates the quantitative capabilities of coated blade spray (CBS) mass spectrometry (MS) for the concomitant analysis of multiple target substances in biofluid spots. In CBSMS the analytes present in a ... 
Quantitative Analysis of Petroleum Hydrocarbons (PHC) in Soils and Chemically Augmented Plant Growth Promoting Rhizobacteria Enhanced Phytoremediation Systems.
(University of Waterloo, 20170515)Petroleum hydrocarbons (PHC) are a complex mixture of organic compounds, which can negatively impact terrestrial ecosystems. The Canadian Council of Ministers of the Environment (CCME) provides recommendations on the ... 
Quantitative Characterization of Polymeric Engine Oil Additives in Solution by Fluorescene
(University of Waterloo, 20150824)The solution behavior of several polymeric oil additives has been characterized by using fluorescence. First, the chemical composition of the polyisobutylenebased dispersants was determined by using the inherent fluorescence ... 
Quantitative Characterization of PyreneLabeled Macromolecules in Solution by Global Analysis of Fluorescence Decays
(University of Waterloo, 20120427)A series of pyrene endlabeled monodisperse poly(ethylene oxide)s (PEO(X)Py2 where X represents the number average molecular weight (Mn) of the PEOs and equals 2, 5, 10 and 16.5 K) and one pyrene monolabeled PEO (PEO(2K)Py1) ... 
Quantitative Characterization of the Molecular Dimensions of Flexible Dendritic Macromolecules by Pyrene Excimer Fluorescence
(American Chemical Society, 20180212)Eight pyrene labeled dendrons (PyLDs) were prepared with a polyester backbone of bis(hydroxymethyl)propionic acid and the monomer and excimer fluorescence decays of the PyLDs were acquired and fitted according to the ... 
A Quantitative Model of the Initiation of DNA Replication in Saccharomyces cerevisiae
(University of Waterloo, 20120501)A crucial step in eukaryotic cell proliferation is the initiation of DNA replication, a tightly regulated process mediated by a multitude of protein factors. In Saccharomyces cerevisiae, this occurs as a result of the ... 
Quantitative modeling of nitrogen cycling along the river continuum: streambed sediments, reservoirs, and isotopes
(University of Waterloo, 20180926)The vast release of anthropogenically produced reactive nitrogen (N) into the environment, by agricultural activities, energy production and municipal wastewater, has led to a variety of consequences for atmospheric, ... 
Quantitative Modelling of the Shifts and Splitting in the IR Spectra of SF<sub>6</sub> in an Ar Matrix
(University of Waterloo, 2005)An infrared active polyatomic molecule has several vibrational modes, each of which has a characteristic frequency. If the molecule is trapped in a matrix of perturbing atoms, those vibrational frequencies will shift, ... 
Quantum Algorithmic Techniques for FaultTolerant Quantum Computers
(University of Waterloo, 20191001)Quantum computers have the potential to push the limits of computation in areas such as quantum chemistry, cryptography, optimization, and machine learning. Even though many quantum algorithms show asymptotic improvement ...
