Transition Metal Oxide Nanoparticles Decorated Carbon Nanomaterials as Earth-Abundant Electrocatalysts for Zinc-Air Batteries
DownloadFall 2022
As awareness of global warming increases and the geopolitically influenced energy supply fluctuates, the global economy is in dire need of a transition from fossil fuels to renewable energy sources. Although renewable energies are sustainable and have favorable environmental impacts, they suffer...

Indicators of gold mineralization in the Yellowknife greenstone belt: a lithogeochemistry and mineralogy study
DownloadSpring 2021
Geochemical signatures within an economic deposit are an important indicator used in the exploration of high-grade mineralization. In this study, we aim to identify elements that can act as geochemical indicators for orogenic gold within the Yellowknife greenstone belt that allow the...

Nutrient and carbon export from a tidewater glacier to the coastal ocean in the Canadian Arctic Archipelago
DownloadSpring 2021
As glaciers melt, a range of on-, in-, and under-glacier processes modify and export freshwater and sediments to the ocean. This glacial runoff may influence biological productivity in coastal ecosystems by supplying essential nutrients and labile carbon. Previous studies of glacial meltwater...

Seeing the forest for the soil: topographic controls on soil carbon dynamics in the boreal mixedwood forest
DownloadFall 2018
Boreal forest soils store an estimated 272 Pg of carbon. Due to a high degree of spatial heterogeneity, there is a wide range in carbon stores in this ecosystem. Changes in topography and forest structure are important to carbon distribution, influencing the soil microclimate and the chemical...

Spring 2016
Understanding factors affecting elemental carbon stocks on Alberta’s grasslands is of special importance with recent policy shifts focusing on climate change and carbon (C) emissions. A large part of Alberta is native prairie utilized by the beef industry. This study examined soil and vegetation...

Dissolved Organic Carbon Mobilization and Degradation Patterns in Retrogressive Thaw Slumps of the Peel Plateau, Northwest Territories, Canada
DownloadFall 2016
Anthropogenic climate change has affected the Canadian Arctic cryosphere, accelerating the development of retrogressive thaw slumps (RTS) across the Peel Plateau, NWT, Canada. RTS result from the thawing of ice-rich permafrost and develop due to ablation of ground ice exposed in the slump...

Diagenetic Controls on Hydrothermal Fluid Flow in the Osiris, Isis, and Isis East Carlin-Type Gold Showings, Nadaleen Trend, Yukon
DownloadFall 2015
Following ATAC Resources Ltd.’s 2010 discovery of the gold prospects in the Nadaleen Trend (Central Yukon), company geologists and consultants determined that Precambrian carbonate rocks within the trend contain large endowments of gold located in the hinges of anticlines and fault zones. ...

The Influence of Specific Ions and System Architecture on the Recognition and Reactivity of Two Charged Materials: DNA-Modified Gold Nanoparticle Aggregates and Planar Silica
DownloadFall 2014
DNA functionalized gold nanoparticles (GNP–DNA) offer simple colorimetric nucleic acid sensing with high selectivity and sensitivity. Consequently, they are promising in genetic profiling, disease diagnostics, and forensic applications. In the presence of a target nucleic acid, GNP–DNA forms...

Fall 2014
This thesis is focused on the Si-based anode materials for lithium-ion batteries (LIBs) as well as biomass-derived carbons for LIBs and sodium-ion batteries (NIBs). In our first attempt we investigated the effect of the support growth substrate as well as of aluminum coating layers on the...

Development of High Efficiency and New Selectivity Liquid Chromatographic Phases for the Separation of Ionic and Hydrophilic Analytes
DownloadFall 2013
Separation of low molecular weight ions and hydrophilic analytes is achieved by high performance ion chromatography (IC) and hydrophilic interaction liquid chromatography (HILIC). The goal of this thesis was three-fold: to increase the efficiency of IC separations by employing small particles; to...
