Scheduling process operations under uncertainty and integration with long term planning
(University of Waterloo, 2022-09-22)This thesis centers upon the application of mathematical modelling, optimization theory and uncertainty analysis to the problem of scheduling batch operations for large scale industries. Over the years, decision making ... -
Seeding Induced Assembly of Ionic-Complementary Peptide EAK16-II
(University of Waterloo, 2004)Seeding is an important variable in controlling or directing the assembly of peptides. The presence of impurities, responsible for creating a 'dip' in the surface tension versus peptide concentration profile, is used to ... -
Segregation of chain ends to the surface of a polymer melt: effect of surface profile versus chain discreteness
(Springer, 2016)Silberberg has argued that the surface of a polymer melt behaves like a reflecting boundary on the random-walk statistics of the polymers. Although this is approximately true, independent studies have shown that violations ... -
Selectively leaching the iron-removed bauxite residues with phosphoric acid for enrichment of rare earth elements
(Elsevier, 2019-11-15)Bauxite residue (BR) is a hazardous industrial waste and also becomes an important reserve of rare earth elements (REE). An elegant process for achieving separation of REEs against silica from an iron-removed BR was ... -
Self-assembled Metal Organic Framework Microflowers as Polysulfides Immobilizers for Lithium Sulfur Batteries
(University of Waterloo, 2019-09-18)A unique flower-like metal organic framework (ZnHMT) is synthesized by a facile and efficient method. The obtained ZnHMT microflowers were employed for the construction of a multifunctional interlayer towards improved Li-S ... -
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 ... -
Self-Assembling Peptide-Carbon Nanotube Dispersions and Hydrogels for Tissue Engineering and Biosensor Applications
(University of Waterloo, 2015-05-25)Carbon nanotubes (CNTs) are attractive functional materials for use in a broad range of fields due to their unique mechanical and electrical properties. However, their hydrophobic nature is a major problem for some of these ... -
Self-Assembling Peptides as Potential Carriers for the Delivery of the Hydrophobic Anticancer Agent Ellipticine
(University of Waterloo, 2008-03-11)Self-assembling peptides have emerged as new nanobiomaterials in the areas of nanoscience and biomedical engineering. In this category are self-assembling, ionic-complementary peptides, which contain a repeating charge ... -
Self-discharge of Rechargeable Hybrid Aqueous Battery
(University of Waterloo, 2014-05-12)This thesis studies the self-discharge performance of recently developed rechargeable hybrid aqueous batteries, using LiMn2O4 as a cathode and Zinc as an anode. It is shown through a variety of electrochemical and ex-situ ... -
Self-polymerized Dopamine Thin Film as Bioadhesive
(University of Waterloo, 2012-01-25)Dopamine is an interesting biomolecule that functions as a neurotransmitter in the brain. It has been found able to stick to almost all surfaces due to its unique catecholamine structure. Under alkaline conditions, the ... -
Self/Co-Assembling Peptide-based Nanocarriers for Anticancer Drug Delivery
(University of Waterloo, 2014-04-24)Current diagnostic and therapeutic nanocarriers, including liposomes, micelles, and polymeric- and protein-based nanoparticles, are designed to have key functional properties such as: (i) longevity in the bloodstream, ... -
Sensing guanine and its derivatives: From molecular recognition to applications
(Elsevier, 2020-11)Guanine plays an indispensable role in building nucleic acids, and its derivatives take part in various cellular functions such as regulating biological reactions and signal transduction. Monitoring the levels of guanine ... -
Sensor Array for Volatile Organic Compounds based on Doped Poly (2,5-dimethyl aniline)
(Wiley, 2016-12)A sensor array containing five different sensing materials has been created that is able to distinguish between six different volatile organic compounds (VOCs) at an analyte concentration of 5 ppm. While none of the sensing ... -
Sensor Fault Detection and Isolation for Degrading Lithium-Ion Batteries in Electric Vehicles
(University of Waterloo, 2020-01-07)With the increase in usage of electric vehicles (EVs), the demand for lithium ion (Li-ion) batteries is also on the rise. A Li-ion battery pack in an EV consists of hundreds of cells and requires a battery management system ... -
Separation of caprolactam from water by membrane processes
(University of Waterloo, 2014-01-24)Caprolactam (C6H11NO, CPL) is the precursor to nylon 6. Production of caprolactam generates wastewater streams that contain a small amount of caprolactam. The objective of this study is to evaluate appropriate separation ... -
