Corporate Social Performance of Firms in Conflict Mineral Global Supply Chains
(University of Waterloo, 2016-10-31)The corporate social performance of a diverse group of firms in global supply chains was assessed. Corporate social responsibility (CSR) is a global issue that affects not only enterprises themselves, but also their ... -
DNA templated fluorescent gold nanoclusters reduced by Good’s buffer: from blue emitting seeds to red and near infrared emitters
(NRC Research Press, 2015-01-22)DNA-templated fluorescent gold nanoclusters (AuNCs) have been recently prepared showing higher photostability than the silver counterpart. In this work, we examined the effect of pH, DNA length, DNA sequence, and reducing ... -
Effects of Ultrasound in Microelectronic Ultrasonic Wire Bonding
(University of Waterloo, 2007-12-12)Ultrasonic wire bonding is the most utilized technique in forming electrical interconnections in microelectronics. However, there is a lacking in the fundamental understanding of the process. In order for there to be ... -
Glacial Dispersion at the Canadian Malartic Gold Deposit
(University of Waterloo, 2024-04-19)A novel drift prospecting approach detected components from previously established bedrock footprints at the world-class Canadian Malartic gold deposit within the site’s surrounding Quaternary sediments. The measured glacial ... -
Gold Surface Nanostructuring for Separation and Sensing of Biomolecules
(University of Waterloo, 2016-12-14)Detecting biomolecules in physiological environments is critical to health care and environmental monitoring. In this work, we study and use gold surfaces for biomolecule detection while incorporating nanoscale ... -
Hydrothermal Alteration and Exploration Vectors at the Island Gold Deposit, Michipicoten greenstone belt, Wawa, Ontario
(University of Waterloo, 2019-05-01)The Island Gold deposit is a high-grade orogenic gold deposit located in the Goudreau Lake Deformation Zone (GLDZ), within the Michipicoten greenstone belt. This belt is situated within the larger Wawa-Abitibi terrane which ... -
A Label-Free Biosensor for Heat Shock Protein 70 Using Localized Surface Plasmon Resonance
(University of Waterloo, 2012-07-09)Heat shock protein 70 (HSP70) is an important health related biomarker, being implicated as an early stage cancer marker and as an indicator of cardiac health. It also has important implications in wildlife environmental ... -
Light-Activated Metal-Coordinated Supramolecular Complexes with Charge-Directed Self-Assembly
(American Chemical Society, 2013-02-21)Metal-coordinated materials are attractive for many applications including catalysis, sensing, and controlled release. Adenine and its derivatives have been widely used to generate many coordination complexes, polymers, ... -
A platinum shell for ultraslow ligand exchange: unmodified DNA adsorbing more stably on platinum than thiol and dithiol on gold
(Royal Society of Chemistry, 2015-08-04)Due to the ultraslow ligand exchange rate on Pt, non-thiolated DNA is adsorbed on platinum nanoparticles (PtNPs) more stably than thiolated and even dithiolated DNA on AuNPs. Adsorption kinetics, capacity and stability are ... -
The Role of Transverse Faults in Late Gold Mineralization: A Structural Study of the Maskinonge Lake Fault, Michipicoten Greenstone Belt, Ontario
(University of Waterloo, 2023-10-25)The Maskinonge Lake fault is a late NW-striking fault that occurs at a high angle to the structural features of the gold-producing Goudreau Lake Deformation Zone (GLDZ) in the Michipicoten greenstone belt. The fault is ... -
Structural Controls and Deformation History of the Orogenic Island Gold Deposit, Michipicoten Greenstone Belt, Ontario
(University of Waterloo, 2019-07-11)Island Gold is a currently producing mine on the high-grade orogenic Island Gold deposit in northern Ontario. It is located within the southern domain of the regional Goudreau Lake Deformation Zone (GLDZ), which trends ... -
THE TULU KAPI GOLD DEPOSIT OF THE WESTERN ETHIOPIAN SHIELD: STRUCTURAL FRAMEWORK, U-PB ZIRCON GEOCHRONOLOGY AND PARAGENESIS
(University of Waterloo, 2019-04-10)Gold production dates back millennia in the Arabian Nubian Shield. Most of the mined deposits are in the northern portions of the shield, with little know about its southern extent. Tulu Kapi is a rare example of a gold ...
