Dependence of the Interfacial Adhesion between Two Different Types of Material on their Electron Work Function and Electrical Conductivity
DownloadFall 2021
We observed and investigated a novel interfacial phenomenon related to the dependence of interfacial bonding or adhesive force (Fad) between two substances on the difference in their Electron Work Functions (EWF) or Δφ, and developed a model to quantify such a dependence. First, using...

This work aims to conduct a techno-economic feasibility analysis of adopting a hybrid approach to hydrogen generation. This includes grey hydrogen sourced from natural gas using Steam Methane Reforming (SMR) and green hydrogen from renewable energy. The key focus is on assessing the environmental...

Exploring Atomic Force Microscopy To Probe Charge Transport Through Molecular Films And For The Development Of Combinatorial Force Microscopy
DownloadFall 2012
Since the invention of the atomic force microscope (AFM), this technology has had profound implications in the study of material science and molecular biology. The ability to visualize and perform quantitative analysis of the nanoscale properties of surfaces has provided great insights into...

Spring 2020
On a perfect hydrogen-terminated Si(100)-2x1 surface, each surface silicon atom is capped with exactly one atom of hydrogen. When one of the capping hydrogen atoms is removed, the now unsatisfied orbital of the underlying silicon atom is exposed at that site. This site is better known as a...

Casing pipes used in sour service are prone to two forms of failure: hydrogen induced cracking (HIC) and sulfide stress cracking (SSC). The objective of this thesis is to investigate the resistance of L80 ERW and Seamless steel pipe, with five different chemical compositions, to both HIC and SSC....

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...

Machine Learning for Emission Modeling of Fossil-fueled and Hydrogen-fueled Internal Combustion Engines
DownloadFall 2023
Development of fast and accurate emission models for engine-out and tailpipe of internal combustion engines (ICEs) using machine learning (ML) and hybrid methods are the focus of this thesis. The application is on medium and heavy-duty vehicles powered by both fossil fuels and alternative fuels...
