Catalytic Conversion of Waste Plastics into Value-Added Chemicals
(University of Waterloo, 2022-09-08)Plastics are indispensable in many industries (such as packaging and transportation) owing to its durability, diversity and versatilities. However, the decomposition rate of plastic is far from generation speed. The plastic ... -
Catalytic Distillation: Modeling and Process Development for Fuels and Chemicals
(University of Waterloo, 2017-05-09)Catalytic Distillation (CD) is a hybrid green reactor technology that utilizes the dynamics of simultaneous reaction and separation in a single process unit to achieve a more compact, economical, efficient and optimized ... -
Catalytic Glycerol Hydrogenolysis to Produce 1,2-propanediol with Molecular Hydrogen and in situ Hydrogen Produced from Steam Reforming
(University of Waterloo, 2014-04-15)Biodiesel has shown great promise to supplement the fossil diesel since it is a renewable energy resource and is environmentally friendly. However, the major obstacle to biodiesel large scale commercialization is the high ... -
Catalytic Hydrogenation of Nitrile Rubber in High Concentration Solution
(University of Waterloo, 2011-08-24)Chemical modification is an important way to improve the properties of existing polymers, and one of the important examples is the hydrogenation of nitrile butadiene rubber (NBR) in organic solvent by homogeneous catalysis ... -
Catalytic Hydrogenolysis of Glycerol to 1-Propanol Using Bifunctional Catalysts in an Aqueous Media
(University of Waterloo, 2016-10-26)Biodiesel is an attractive alternative fuel obtained from renewable resources and glycerol is produced as a major byproduct in the biodiesel industry. Upgrading glycerol to other valuable chemicals will contribute to an ... -
The Catalytic Intramolecular Friedel-Crafts Acylation of Meldrum's Acid Derivatives and The Total Synthesis of Taiwaniaquinol B
(University of Waterloo, 2005)The intramolecular Friedel-Crafts acylation of aromatics with Meldrum?s acid derivatives catalyzed by metal trifluoromethanesulfonates and other Lewis acids is reported. Meldrum?s acids are easily prepared, functionalized, ... -
Catalytic Potential and Ligand Binding Properties of the Malachite Green RNA Aptamer
(University of Waterloo, 2008-09-18)The malachite green aptamer was originally engineered for binding specificity to malachite green (MG). The environment inside the aptamer’s electronegative binding pocket was previously harnessed to catalyze an ester ... -
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 ... -
Catching the Public Eye: The Body, Space, and Social Order in 1920s Canadian Visual Culture
(University of Waterloo, 2007-01-05)In the cultural upheaval of the 1920s, Canadians became particularly invested in looking at and debating women’s images in public. This dissertation looks at how English-Canadians debated, accepted, and challenged modernity ... -
Categorization and Detection of Energy Bugs and Application Tail Energy Bugs in Smartphones
(University of Waterloo, 2016-09-16)Smartphones are the most ubiquitous and popular hand-held devices because of their rich set of features and wide variety of services. However, their daily use is hampered by their high energy consumption, which forces ... -
Cationic Cellulose Nanocrystals (CNCs) for Organic and Inorganic Colloids Flocculation
(University of Waterloo, 2016-01-27)Cellulose nanocrystals were modified for use as novel flocculants by taking advantage of the extended cationic polymeric chains on CNCs. They were evaluated using both organic colloids and inorganic bentonite clay particles. ... -
Cationic Cellulose Nanocrystals for the Flocculation of Mature Fine Oil Sands Tailings
(University of Waterloo, 2021-04-22)As the volume of oil sands tailings continues to increase each year with a concurrent need for better flocculants to replace the inorganic electrolytes and synthetic polymers, natural polymers are being considered as ... -
