Middleton, Steven Mark William
A numerical model and software interface for the design and modelling of Stirling engines was presented. This model was developed to suit low-temperature Stirling engines, those that run at source temperature of less than 150 °C and run at speeds where temporarily developed losses become...

Atomic Force Microscopy Characterization of Hydrogen Terminated Silicon (100) 2x1 Reconstruction
DownloadFall 2015
Non-contact Atomic Force Microscopy (NC-AFM) is a Scanning Probe Microscopy tool offering unique non-perturbative analysis of surfaces and adsorbates at the atomic scale. AFM precisely oscillates a sharp tip above a sample. By monitoring the shift in resonance frequency of a quartz tuning fork...

Breaking with tradition: Fischer—Tropsch gas loops and modelling vapor—liquid—liquid equilibrium
DownloadFall 2015
Fischer—Tropsch gas loops have been in use for nearly a century, producing synthetic fuels and petrochemicals. Yet there still remain many opportunities to expand its uses, update the gas loop with new technology, as well as better understand at a fundamental level the way the products behave....

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...

20Cr-32Ni-1Nb stainless steel alloys are commonly used in hydrogen reformer manifolds for transporting hot hydrogen by-products at 750-950 celcius. After long periods of exposure, embrittling secondary carbides and intermetallic phases can precipitate at the grain boundaries which can drastically...

This dissertation investigates the influence of surface heterogeneities on colloid deposition. First, deposition of colloidal particles on a nanofiltration membrane during cross flow membrane filtration was studied under different operating pressures and solution chemistries. An atomic force...

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...

Developing High Precision Heat Capacity Correlations for Organic Solids and Liquids - Extending to Biofuels and Sugars
DownloadSpring 2018
There is a great need for easily accessible and accurate physical property data in the heavy oil industry, the pharmaceutical industry, and other heavy molecule guided productions. In recent years, high precision predictive correlations for isobaric heat capacities of heavy and ill-defined...
