Fall 2011
High aspect ratio microelectromechanical structures have been found, in the literature, to collapse due to capillary forces of liquids. In this dissertation, mathematical models are developed to study (i) the collapse of a microstructure represented by a double cantilevered beam (DCB) with a free...

Conductive Atomic Force Microscopy Study of Electron Transport Through Diazonium Derived Films and Mixed – Mode Bonded Layers on Gold and Carbon Surfaces
DownloadSpring 2012
For Molecular Electronics to become a viable replacement or complitment to current elec- tronic devices a fundamental understanding of device operation and functionality is needed. This work explores electron transport through diazonium derived molecular junctions via conductive atomic force...

Cryo-electron microscopy of SERCA interacting with oligomeric phospholamban and oligomeric sarcolipin
DownloadFall 2011
In 2007, heart disease was the second leading cause of death in Canadians. In heart muscle cells, calcium (Ca2+) is released from the sarcoplasmic reticulum (SR) during contraction and must be replenished for relaxation to occur. Three proteins restore Ca2+ to the SR following contraction: the...

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 provides a guideline for gecko inspired dry adhesive design and simulation. Mechanical property testing for several polymers commonly used in gecko adhesives (Kraton G1657 thermoplastic elastomer, ST-1060, and ST-1087 polyurethane elastomers) allowed hyperelastic and viscoelastic...

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...

Ultrasound imaging has great potential in intraoral diagnosis, due to its portability, low cost, and low safety risks. A couplant is normally placed between transducers and tissues for better ultrasound image quality. If applied intraorally, the couplants should possess good stability in water,...

Spring 2013
Electrografting permits bonding of an organic film to a conductive substrate. It is therefore important to control the formation of organic films as best as possible and to understand the linkage between the organic film and the substrate as best as possible. This work explores electrografting of...

Examination of the Regulation of Phosphorylation Events in Macrophage Adhesion and Response to Zymosan
DownloadFall 2012
Macrophages play a central role in innate immunity, most notably in tissue repair, phagocytosis of dead or infected cells, secretion of chemokine and cytokines at sites of infection, as well as the activation of other immune cells. These roles are highly dependent on their capacity to migrate...

Experimental Investigation on Interfacial and Surface Phenomena of Clathrate and Semi-clathrate Hydrates
DownloadFall 2023
Clathrate hydrates are compounds where guest molecules are trapped in cages formed between water molecules via hydrogen bonding. They have many promising applications, such as gas storage, energy storage, gas mixture separation and seawater desalination. They may also form inside the oil & gas...
