Fall 2023
Three new Re(I) photocatalysts were prepared by synthesizing imidazole and imidazolium dyes based on carbazolyl dicyanobenzene derivatives and physically linking them to a Re metal centre for the photochemical reduction of CO2. The imidazolium dyes were of interest because they are precursors to...

Investigation of Highly Effective and Stable Electrocatalysts for Electrochemical CO2 Reduction at Room and Elevated Temperatures
DownloadFall 2017
To effectively reduce and utilize atmospheric CO2, electrochemically converting it to CO on an efficient and stable electrocatalyst at room and elevated temperatures has attracted extensive interests. However, present electrocatalysts usually suffer from sluggish kinetics, high overpotential, low...

The genesis of the Gayna River carbonate-hosted Zn-Pb deposit
Fall 2009
Geochemical analyses on samples from the Mississippi Valley Type Gayna River deposit, Northwest Territories, Canada, have resulted in the definition of three ore stages and a deposit genesis model. Pb/Pb and Re/Os isotopic analyses indicate that the mineralization at Gayna River was emplaced...
