Control of D-Spacing and Graphitic Defects in Asphaltene-Derived Hard Carbons for Energy Storage
DownloadSpring 2024
With the increasing demand for energy storage and declining lithium stores around the globe, sodium is emerging as an alternative source due to its natural abundance and similar reaction kinetics and chemical properties to lithium. While sodium-ion and lithium-ion batteries started development at...

Crack Growth Behaviour of Pipeline Steels under Variable Pressure Fluctuations in a High pH Environment
DownloadSpring 2021
High pH Stress Corrosion Cracking (HpHSCC) in the pipeline steel has been a threat for buried pipeline integrity since the first occurrence in the 1960s. Much research has been devoted to understanding the causes of this phenomenon and remedies for mitigation of HpHSCC failures. In addition to...

Effect of unloading rate on surface crack growth during underload cycles in X-65 pipeline steel exposed to near-neutral pH environments
DownloadSpring 2019
This thesis has studied the crack growth behaviour of fully-coated, partially-coated, and fully-exposed semi-elliptical cracks immersed in a near-neutral pH environment with an applied cathodic potential. The effects of adding a one-hour monotonic hold and waveform shape were explored. The...

Fatigue Crack Growth Behaviour in Pipeline Steels under Mean Load Pressure Fluctuation in Near-Neutral pH Environment
DownloadFall 2021
This research aimed to understand the effect of mean load pressure fluctuations on crack growth in near-neutral pH (NNpH) environment. This work contributes to a larger effort to develop a crack growth predictive model based on variable amplitude loading. The motivation for this study is that...
