Although evaporation is considered to be a surface phenomenon, the rate of molecular transport across a liquid–vapor boundary is strongly dependent on the coupled fluid dynamics and heat transfer in the bulk fluids. Recent experimental thermocouple measurements of the temperature field near the...

Crude oils contain a distribution of molecules with diverse chemical structures and molecular weights. Asphaltenes are considered the most problematic of these structures. We have investigated the adsorption and aggregation of asphaltenes on surfaces using scanning probe microscopy. Modifying the...

Gallium Nitride (GaN) is recognized as one of the best candidates for high-power high-frequency metal-oxide-semiconductor field-effect-transistors (MOSFETs). The critical component to enable this technology is the development of a robust oxide with low density of defects and preferential mobility...

A fundamental understanding of the molecular interactions between asphaltene molecules in bulk and at oil-water interface is of great value in crude oil production. Yet, the chemical composition and molecular structures of asphaltenes are not fully understood. The objective of this study is to...

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...
