This thesis is focused on the design of a series of bi-metallic catalyst for enhancing the hydrogen sorption kinetics of magnesium hydride. We have utilized thin films deposited by magnetron sputtering technique as model systems to study various alloys and compositions. It has been known that the...
This thesis presents a thorough examination of the corrosion and fouling behaviour of crude oil at refining conditions on industrially applicable heat transfer surfaces. The depletion of light sweet crude oil reserves means that the processing of ever heavier and more sour crude oils is...
High Performance Germanium-based Anode Materials for Lithium-ion and Sodium-ion Rechargeable BatteriesDownload
In this thesis the electrochemical performance of germanium nanowires (GeNWs) as anode for lithium-ion batteries (LIBs) and tin-germanium-antimony (Sn-Ge-Sb) thin films as anode for sodium-ion batteries (NIBs) have been investigated. Scientific literature shows a substantial study-to-study...
This thesis outlines the development of two platforms for integrating microfabricated sensors with high pressure feedthroughs for application in hostile high temperature high pressure environments. An application in oil well production logging is explored and two sensors were implemented with...
Microstructure-property correlation in magnesium-based hydrogen storage systems- The case for ball-milled magnesium hydride powder and Mg-based multilayered compositesDownload
The main focus of this thesis is the characterization of defects and microstructure in high-energy ball milled magnesium hydride powder and magnesium-based multilayered composites. Enhancement in kinetics of hydrogen cycling in magnesium can be achieved by applying severe plastic deformation. A...
Nanoscale resonators fabricated from metallic alloys, and modeling and simulation of polycrystalline thin film growthDownload
Part I - We have designed a binary metallic alloy for nanoscale resonator applications. We used magnetron sputtering to deposit films with different stoichiometries of aluminum and molybdenum and then characterized the microstructure and physical properties of each film. A structure zone map is...
Hydrogen storage has been a key area of focus in the clean energy field for over a decade, as it is a major obstacle to the widespread adoption of fuel cells for mobile applications. The aim of this thesis research was to improve the Magnesium Aluminum hydrogen storage system in order to make it...
To tailor the hydrogen sorption properties of magnesium, improve its poor kinetics and alter its thermodynamics properties, sputtered multilayer Mg-based thin films were prepared in which Mg layers were confined by AlTi layers. Multilayer samples of different Mg thickness showed relatively long...
This thesis is focused on the studying the role that model sulfur-containing molecules have in corrosion reactions on relevant metallurgies. This was done by using a design of experiments where a number of sulfur-based compounds were reacted with various metallurgies. The 8 model sulfur compounds...
We have designed and engineered bi-catalyst magnesium hydride composites with superior sorption performance to that of ball milled magnesium hydride catalyzed with the individual baseline catalysts. We have examined the effect of single-walled carbon nanotube (SWCNT)-metallic nanoparticle...
