The Influence of Specific Ions and System Architecture on the Recognition and Reactivity of Two Charged Materials: DNA-Modified Gold Nanoparticle Aggregates and Planar Silica
DownloadFall 2014
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...

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...

Poly (N-isopropylacrylamide) microgel-based etalons and etalon arrays for determining the molecular weight of polymers in solution
Download2013
Serpe, Michael J., Islam, Molla R.
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...

We develop a method for searching for Hajós constructions. Our results include the discovery of new constructions for some well-known graphs, including the Grötzsch graph, Chvátal graph, and Brinkmann graph; also, we prove that the first two of these are shortest possible constructions. These are...

Indicators of gold mineralization in the Yellowknife greenstone belt: a lithogeochemistry and mineralogy study
DownloadSpring 2021
Geochemical signatures within an economic deposit are an important indicator used in the exploration of high-grade mineralization. In this study, we aim to identify elements that can act as geochemical indicators for orogenic gold within the Yellowknife greenstone belt that allow the...

Chalaturnyk, R., Azam, S., Scott, J. D.
Abstract: Laterites are the main source of economic metals such as nickel and cobalt. In many parts of the globe, these metals are extracted using the pressure acid leach operation. An efficient rate of sedimentation and a high solids content of the material are two prerequisites for this...

Geochemical Characterization and Fluid History of the Tiger Zone; a Tertiary Distal Carbonate-Replacement Intrusion-Related Gold Deposit, Central Yukon
DownloadSpring 2013
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,...

Diagenetic Controls on Hydrothermal Fluid Flow in the Osiris, Isis, and Isis East Carlin-Type Gold Showings, Nadaleen Trend, Yukon
DownloadFall 2015
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. ...

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...
