Investigation of the Effects of Biofouling on the Hydraulic Properties of Wells in Fractured Bedrock Aquifers
(2007-12-18)The objective of this study is to improve the understanding of the effect of biofilm growth and biofouling on well performance in a fractured rock aquifer. The study was conducted by investigating biofouling in several ... -
Investigations of Asphaltene-Metal Interactions
(2008-02-11)Asphaltenes are the most polar fraction of petroleum that can precipitate due to changes in pressure, temperature and composition which may be encountered during petroleum production and transportation. The precipitated ... -
Kinetic Modeling of Homo- and Co- Polymerization of Water-Soluble N-vinyl Monomers
(2011-12-22)Functional water-soluble polymers find applications in a variety of fields including waste-water treatment, pharmaceuticals, cosmetics, drug delivery, and hygiene. Despite the increased demand for these products, understanding ... -
Kinetics and Modeling of Free Radical Aqueous Phase Polymerization of Acrylamide with Acrylic Acid at Varying Degrees of Ionization
(2015-09-03)Water soluble polymers find applications in both consumer (e.g. superabsorbers in diapers, antiscalants in laundry detergent, and thickeners in shampoo) and industrial applications (e.g. antiscalants, antiflocculants and ... -
Kinetics and Modeling of Radical Copolymerization of Water-Soluble Cationic Monomers
Polyelectrolytes (PELs) are a special class of charged water-soluble polymers utilized in both consumer and industrial applications such as pharmaceuticals, cosmetics, waste-water treatment, flocculating agents, oil drilling ... -
Kinetics, Synthesis and Characterization of copolymers containing the bio-renewable monomer g-methyl-a-methylene-g-butyrolactone (MeMBL)
(2011-04-26)The bio-renewable monomer γ-methyl-α-methylene-γ-butyrolactone (MeMBL) has been thoroughly investigated in this thesis. MeMBL is a relatively unstudied monomer that had received little attention since the early 1980’s but ... -
Laser Transmission Welding of Polybutylene Terephthalate and Polyethylene Terephthalate Blends
(2010-08-31)Laser Transmission Welding (LTW) involves localized heating at the interface of two pieces of plastic (a laser transparent plastic and laser absorbing plastic) to be joined. It produces strong, hermetically sealed welds ... -
Latent Amine Cures of Brominated Poly(isobutylene-co-isoprene)
(2010-02-02)The allylic bromide functionality within brominated poly(isobutylene-co-isoprene), or BIIR, alkylates primary amines repeatedly to generate thermoset products at reaction rates that are too fast to support commercial rubber ... -
Leukocyte Response to Elastin-Like Polypeptide Coatings
(2013-10-15)Small diameter synthetic vascular grafts have yet to be clinically successful due to luminal narrowing from thrombosis and intimal hyperplasia. Current attempts to address this issue include the development of materials ... -
Living Radical Polymerization in Aqueous Dispersed Systems with Water-Soluble Catalysts
(2015-10-03)Living radical polymerization is an important technique for synthesizing advanced macromolecules including block copolymers. Since its discovery in the early 1990s the capability of the field has expanded with new types ... -
Living/controlled Polymerization Conducted in Aqueous Based Systems
(2007-09-25)In the last decade processes known as living/controlled radical polymerizations (L/CRP) have been developed which permit the synthesis of high-value specialty polymers. Currently, the three processes that have demonstrated ... -
Living/Controlled Radical Polymerization in a Continuous Tubular Reactor
