Fall 2009
The use of rayon in 1920s and 1930s garments confronts conservators with new challenges: definitive fibre identification involves more than basic microscopy and treatment can be difficult with little available research on early rayon and its conservation. Rayon is expected to degrade similarly to...

Spring 2011
In this thesis, measurement and analysis of colloidal forces between an atomic force microscope (AFM) probe and a topographically patterned substrate are reported. The energy between the patterned substrate and a smooth flat plate was characterized mathematically using Surface Element Integration...

Investigation of the Adsorption of Model and Oil Sands Process-Affected Water Naphthenic Acids on Graphite
DownloadSpring 2015
Naphthenic acids (NAs) are constituents of bitumen in the oil sands deposits in northern Alberta, Canada. The extraction process of bitumen creates an enormous amount of wastewater called oil sands process affected waters (OSPW). This OSPW contains elevated concentrations of NAs, and other...

Investigation of the Synthesis, Reactivity and Biological Properties of Various 6-Substituted D-Fructose Derivatives
DownloadFall 2017
The detection of small tumors growing in complex organs, including breast tissue, is a challenge in modern medical imaging. The use of positron emission tomography (PET) and tracer molecules containing radionuclei such as 18F have been of significant value to detect small tumors. The commonly...

Fall 2022
A major challenge that plagues nuclear magnetic resonance (NMR) spectroscopists is the inherently low sensitivity of this workhorse characterization technique. This low sensitivity results in long acquisition times and/or costly isotopic-labelling to obtain good resolution and signal-to-noise...

New Approaches to Thermodynamics-based Predictive Modelling of Gas Chromatography and Comprehensive Two-dimensional Gas Chromatography
DownloadSpring 2019
Thermodynamics-based predictive models of retention in gas chromatography and comprehensive two-dimensional gas chromatography have been demonstrated to provide high prediction accuracy across a wide range of separation conditions. They generally predict better than retention index-based models...

Fall 2015
Organic chemistry has its foundations in the 19th century; since, it has grown into a number of industries affecting our daily lives such as the manufacture of goods and life saving pharmaceuticals. The need for new and increasingly efficient synthetic methods has grown in response to the...

On Organic Liquid Crystal Transfer from Bitumen-Rich to Water-Rich Phases: A Combined Laboratory and SAGD Field Study
DownloadSpring 2014
Hydrocarbon-based liquid-crystal domains were observed in unreacted heavy fractions extracted from Athabasca bitumen and bitumen derived hydrocarbon resource fractions. Transfer of these organic crystalline domains to the water-rich phase during SAGD production is explored here because there...

Fall 2015
Oil sands bitumen is increasingly recovered by injecting steam into reservoirs using the energy intensive Steam assisted gravity drainage (SAGD) process. Interest in improving recovery and energy efficiencies have led to an interest in injecting light hydrocarbons along with or instead of steam...

Regional and local controls of surface water chemistry in the Boreal Plain and Shield transition of Canada
DownloadFall 2010
The Western Boreal Forest exhibits complex hydrogeology juxtaposed with rapid resource development. Predicting surface water chemistry to assess the influence of landuse and climate change is needed. The research purpose was to test if a global model (Gibbs), used to assess water chemistry...
