Hydrogenolysis of Carbon-Carbon Sigma Bonds
(University of Waterloo, 2015-05-22)The modification of benzylic quaternary, tertiary, and secondary carbon centers through Pd-catalyzed hydrogenolysis of Csp3-Csp3 σ bonds is presented. When benzyl Meldrum’s acid derivatives bearing quaternary benzylic ... -
Hydrogeochemical, Mineralogical and Microbial Processes Occurring in Old Sulfide-Rich Tailings
(University of Waterloo, 2015-09-30)The former Sherritt-Gordon Mine, located in Sherridon Manitoba, processed approximately 7.7 Mt of sulfide ore between 1931 and 1951. The Zn-Cu volcanic massive-sulfide ore body yielded Zn and Cu concentrates with minor ... -
Hydrogeochemistry and Trace Element Mobility in an Acidic High-Sulfide Tailings Impoundment After 40 Years of Oxidation
(University of Waterloo, 2024-01-25)Abandoned mine sites can create a legacy environmental contamination issue when the generation of acid mine drainage is allowed to continue with insufficient or absent remediation measures. The South Bay mine, a former ... -
Hydrogeologic Analysis of a Complex Aquifer System and Impacts of Changes in Agricultural Practices on Nitrate Concentrations in a Municipal Well Field: Woodstock, Ontario
(University of Waterloo, 2005)The Thornton Well Field, located in an area of dominantly (~80%) agricultural land-use, produces ~50% of the drinking water for the city of Woodstock. Since the mid 1990?s nitrate concentrations in some of the supply ... -
Hydrogeologic Modelling to Assess Conditions Related to OPG's Proposed Deep Geologic Repository in Tiverton, Ontario
(University of Waterloo, 2008-01-17)A Deep Geologic Repository (DGR) for Low and Intermediate Level (L&IL) Radioactive Waste has been proposed by Ontario Power Generation for the Bruce Nuclear site in Ontario Canada. The DGR is to be constructed at a depth ... -
Hydrophobic and Elastic Forces Experienced by a Series of Pyrene End-Labeled Poly(ethylene oxide)s Interacting with Sodium Dodecyl Sulfate Micelles
(American Chemical Society, 2018-07-30)A series of pyrene end-labeled poly(ethylene oxide)s (Py2-PEO(x) with x equal to 2, 3.4, 5, 6, 7.8, and 10 kg mol–1) were synthesized, and their interactions with SDS micelles were characterized by steady-state and ... -
Hydrophobic Engineering of a Bacterial Nanodimensional Capsule Protein
(University of Waterloo, 2017-07-07)Recently, numerous protein-based nanomedicine platforms have been intensively explored. These systems are usually composed of self-assembling proteins that form controllable systems with different shapes and types. A ... -
Hydrophobic Modification of Starch
(University of Waterloo, 2019-08-27)Starch is a very common polysaccharide with multiple applications in the industry, but the range of physical properties exhibited by that material is relatively limited due to its strongly hydrophilic character. The work ... -
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 ... -
H₂¹⁸O and H₂¹⁶O in Intermediate Mass Star Formation Regions
(University of Waterloo, 2018-09-20)While the process of low mass (LM) star formation is a well studied area of astrophysics, the formation of high mass (HM) stars is much more complicated. The study of intermediate mass (IM) star formation is expected to ... -
