X-ray microscopy of hydrocarbon-clay interactions
One of the critical challenges in the Canadian oil sand industry is improving processes used to separate bitumen from oil sands and to remove clay particulates from produced oil. The fine clay particles are believed to ...
Photoemission electron microscopy and atomic force microscopy of phase- separated Langmuir-Blodgett monolayer thin films
Langmuir-Blodgett (LB) organic monomolecular (monolayer) films containing fatty acids and their perfluorinated counterparts separate into phases under certain conditions. These perfluorinated surfactant containing mixed-phase ...
EX SITU STUDY OF THE EPITAXIAL GROWTH OF N-ALKANE THIN FILMS
A thorough understanding of the growth mechanism in organic thin film growth is necessary to be able to develop devices based on these materials. In particular, there are open questions about the growth mechanism of ...
DEVELOPMENT OF SURFACE SENSITIVITY IN SCANNING X-RAY MICROSCOPY AND NEXAFS SPECTROSCOPY OF ORGANOSULPHUR COMPOUNDS
In this thesis, two objectives related to Near Edge X-ray Absorption Fine Structure (NEXAFS) spectroscopy have been studied. The first objective was to develop surface sensitivity in Scanning Transmission X-ray Microscopy ...
Effect of Intermolecular Interactions on the Carbon 1s Near Edge X-ray Absorption Fine Structure (NEXAFS) Spectroscopy of n-Alkanes
“Matrix effects” in Near Edge X-ray Absorption Fine Structure (NEXAFS) spectroscopy are the spectroscopic changes induced by intermolecular interactions, providing sensitivity to local structure and order in solids and ...
NEXAFS Spectroscopy of Condensed N-alkanes
The carbon 1s Near-Edge X-ray Absorption Fine Structure (NEXAFS) spectra of alkanes vary with chain length, substitution, and phase change. For short gaseous alkanes, the carbon 1s NEXAFS spectra of alkanes are dominated ...
