The electrochemical reduction of para-substituted aryldiazonium cations is a convenient method of introducing chemical functional groups to a surface. The number of conductive surfaces that have been used for this purpose is rapidly expanding. The body of work presented in this thesis will serve...
Gold and silver dressing alloys were created by DC magnetron sputtering and compared with pure silver nanocrystalline dressings using conventional biological and physical characterization techniques. While the gold/silver dressings were weaker antimicrobials than the pure silver nanocrystalline...
Poly (N-isopropylacrylamide) microgel-based etalons and etalon arrays for determining the molecular weight of polymers in solutionDownload
Positively and/or negatively charged poly (N-isopropylacrylamide)-based microgels were deposited on a single substrate and isolated regions of Au overlayers were deposited on top of the microgels. Each spatially isolated Au overlayer region had a different thickness to make an etalon array. We...
The Influence of Specific Ions and System Architecture on the Recognition and Reactivity of Two Charged Materials: DNA-Modified Gold Nanoparticle Aggregates and Planar SilicaDownload
DNA functionalized gold nanoparticles (GNP–DNA) offer simple colorimetric nucleic acid sensing with high selectivity and sensitivity. Consequently, they are promising in genetic profiling, disease diagnostics, and forensic applications. In the presence of a target nucleic acid, GNP–DNA forms...
Geochemical Characterization and Fluid History of the Tiger Zone; a Tertiary Distal Carbonate-Replacement Intrusion-Related Gold Deposit, Central YukonDownload
A paragenetic and geochemical study has resulted in the classification of the Tiger zone as a Tertiary-aged intrusion-related gold deposit. Gold-bearing mineralization occurs in two geochemically and temporally distinct assemblages. The first assemblage contains carbonate-replacement,...
Conductive Atomic Force Microscopy Study of Electron Transport Through Diazonium Derived Films and Mixed – Mode Bonded Layers on Gold and Carbon SurfacesDownload
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...
This thesis is concerned with applications of modern solid-state NMR spectroscopy. Investigations of three quite different types are undertaken, each of which attempt to advance knowledge in the fields of chemistry and NMR. The goal of each project is to obtain insight into the effects of...
Diagenetic Controls on Hydrothermal Fluid Flow in the Osiris, Isis, and Isis East Carlin-Type Gold Showings, Nadaleen Trend, YukonDownload
Following ATAC Resources Ltd.’s 2010 discovery of the gold prospects in the Nadaleen Trend (Central Yukon), company geologists and consultants determined that Precambrian carbonate rocks within the trend contain large endowments of gold located in the hinges of anticlines and fault zones. ...
