Applications of Polyvinylamine in Removal of Heavy Metals from Wastewater by Polymer-Enhanced Ultrafiltration and Adsorption
(University of Waterloo, 2016-01-14)In this study, water-soluble polyvinylamine (PVAm) was used as chelating agent for heavy metal removal from wastewater by polymer-enhanced ultrafiltration (PEUF). The effects of parameters involved in the ultrafiltration ... -
Tracking Uptake, Assembly and Egress of ACAM529 Herpes Simplex Virus Type 2 in Complementary Vero Cells for Enhanced Virus Recovery
(University of Waterloo, 2016-01-06)Herpes simplex virus (HSV) type 2 is the cause of one of the most wide-spread human infections in the world, affecting millions of people and circumventing all past attempts to cure or prevent infection. One of the ... -
Investigations on Drag Reduction by Interactions between Polymer and Surfactant and Polymer and Polymer
(University of Waterloo, 2015-12-22)A large amount of studies have been carried out on pipeline flow with several kinds of drag reducing agents, especially polymers and surfactants. Drag reducing agents, by definition, are additives which help suppress or ... -
Self-assembling Peptide for HIV-1 Vaccine Design
(University of Waterloo, 2015-12-17)Human immunodeficiency virus-1 (HIV-1) is a worldwide epidemic, which cannot be eliminated by any current therapeutics, even with highly active antiretroviral therapy, which only can control virus replication. A safe and ... -
Clarifying Multi-Component Polymerization Kinetics for Tailoring Properties of Acrylamide/Acrylic Acid Copolymers for Enhanced Oil Recovery
(University of Waterloo, 2015-11-30)Among water-soluble polymers, copolymers of acrylamide (AAm) and acrylic acid (AAc) are probably the most common and widely used in practical applications. However, information on the kinetics of the AAm/AAc radical ... -
Towards Designing Composite membranes for CO2 Separation: The Inclusion of Hybrid TiO2-PEG Structures and the Study of their Interfaces
(University of Waterloo, 2015-11-26)This thesis work aims towards designing hybrid membranes for CO2 separation in the post-combustion process. The different methods of existing technologies are compared and assessed for their merit, and the decision of using ... -
Economic Model Predictive Control of Chemical Processes
(University of Waterloo, 2015-11-19)The objective of any chemical process is to transform raw materials into more valuable products subject to not only physical and environmental but also economic and safety constraints. To meet all these constraints in ... -
Immobilization of Gold Nanoparticles for Colourimetric Detection of Biofilms on Surfaces
