Catalytic Separation of Pure Hydrogen from Synthesis Gas by an Ethanol Dehydrogenation / Acetaldehyde Hydrogenation Loop
(University of Waterloo, 2007-09-21)A novel catalytic process for producing high-purity, elevated-pressure hydrogen from synthesis gas was proposed and investigated. The process combines the advantages of low investment and operating costs with the flexibility ... -
Characterization of Dissolved Organic Matter and Reduced Sulfur in Coastal Marine and Estuarine Environments: Implications for Protective Effects on Acute Copper Toxicity
(University of Waterloo, 2009-05-13)Copper-induced toxicity in aqueous systems depends on its speciation and bioavailability. Dissolved organic matter (DOM) and reduced sulfur species can complex copper, influencing speciation and decreasing bioavailability. ... -
The Effects of Copper Availability on Mitochondrial Function in Saccharomyces cerevisiae
(University of Waterloo, 2019-05-23)Copper (Cu) is crucial for cell function and survival and plays important roles in enzyme-catalyzed metabolic processes, transport of cargo through cellular membranes, and protein breakdown. The mitochondria are home to ... -
Impacts of Mixtures of Copper and 1,2-dihydroxyanthraquinone on Physiology and Gene Expression in Lemna gibba L.G-3
(University of Waterloo, 2008-08-21)Polycyclic aromatic hydrocarbons (PAHs) and metals are co-contaminants of aquatic environments near industrial and urbanized areas. Mixtures could result in synergistic toxicity impairing macrophyte growth and potentially ... -
Investigations on Colloidal Synthesis of Copper Nanoparticles in a Two-phase Liquid-liquid System
(University of Waterloo, 2008-09-23)Synthesis of copper nanoparticles by a colloidal recipe in a two-phase liquid-liquid mixture (toluene/water) was investigated. The synthesis recipe used in this work was originally applied for the fabrication of alkylamine-capped ... -
Novel Infusion Procedure for Antimicrobial Fabric Generation
(University of Waterloo, 2023-07-25)Antimicrobial fabrics are fabrics that can kill or slow down the growth of microorganisms that contact the fabric. It is a massive field that is developing due to the sheer variety of fabrics that are possible. Antimicrobial ... -
Process Kinetics of Transient Liquid Phase
(University of Waterloo, 2007-09-24)The problem of inadequate measurement techniques for quantifying the isothermal solidification process during transient liquid phase sintering (TLPS) in binary isomorphous systems such as Ni-Cu, and the resulting uncertainty ... -
Thermoelectric Properties and Stability of Barium Copper Chalcogenides
(University of Waterloo, 2019-09-25)The objective of this thesis was to study the thermoelectric properties of copper chalcogenide-based materials with mixed chalcogen atom sites. Herein, the effect of different concentrations of chalcogen atoms on the ...
