Characterization of a novel weak cation-exchange hydrogel membrane through the separation of lysozyme from egg white
(University of Waterloo, 2012-09-07)Membrane chromatography was investigated as an alternative method to packed-bed chromatography for protein recovery. The purification of lysozyme from egg white with Natrix adseptTM weak cation-exchange membranes was ... -
Cloning and expression of Cyt2Aa1 toxin and characterization of its mode of action
(University of Waterloo, 2010-05-19)The discovery of the pore-forming toxins produced by Bacillus thuringiensis, which are toxic to insects but not to mammalians, has provided a new successful means to control harmful plant-feeding insects biologically. The ... -
Cylindrical colloids on a fluid membrane
(University of Waterloo, 2009-05-22)We theoretically study the adhesion and membrane-mediated interaction of cylindrical colloids to a flat fluid membrane. There are two ways to approach this problem. The first way, based on energy, requires finding the ... -
Desalination of high-salinity water by membranes
(University of Waterloo, 2016-05-12)This study deals with the desalination of high-salinity water using membranes by pervaporation. The membrane performance was characterized with water flux and salt rejection. It was shown that a water flux of 1.6 kg/m²h ... -
Development of self-assembled polyelectrolyte membranes for pervaporation applications
(University of Waterloo, 2006)Electrostatic self-assembly is a simple, yet versatile and environmentally friendly technique. This technique has been widely used in different areas and recently it has also been used to make nano-structured separating ... -
Edible Films from Starch and Chitosan: Formulation and Gas Permeabilities
(University of Waterloo, 2008-12-12)Starch and chitosan films are both known to be effective barriers to gas permeation. Being naturally abundant, renewable, and biodegradable, starch and chitosan films have the potential to replace petroleum-based materials ... -
Electrostatic Modification of Phospholipid and Lipopolysaccharide Membranes
(University of Waterloo, 2012-05-23)Biological membranes are quasi two-dimensional self-assembled structure, primarily serving as a barrier to the leakage of cell’s contents. The main constituents of biological membrane are various amphiphilic lipids that ... -
An Evaluation of Alternatives for Enhancing Anaerobic Digestion of Waste Activated Sludge
(University of Waterloo, 2010-04-30)Waste activated sludge (WAS) is one of the largest by-products of biological wastewater treatment. Anaerobic digestion of WAS is beneficial for several reasons. In an ever increasingly energy conscientious world the ... -
Fabrication of Nanocomposite Filaments for 3D-Printing of Water Treatment Membranes
(University of Waterloo, 2018-09-07)The ever-increasing demand to provide fresh, potable water combined with the continued discharge of industrial and agricultural water pollutant chemicals in the water, require developments in conventional water and wastewater ... -
Investigation of a Novel Hydrogel Anion Exchange Material for the Capture and Purification of Baculovirus
(University of Waterloo, 2014-02-20)Baculoviruses are versatile viruses that can be used as biopestisides, or for the production of recombinant protein and vaccines. Baculoviruses have also been found to be able to transfer genes to mammalian cells. This ... -
OEP15-1 and OEP7.3 Localize to the Outer Envelope of Chloroplasts Using a Novel and Uncharacterized Targeting Pathway
(University of Waterloo, 2021-09-27)Chloroplasts originated from an endosymbiotic event where a Gram-negative cyanobacterium was engulfed by an ancestral eukaryotic cell. The genome of the endosymbiont has since gone through extensive gene transfer to the ... -
Removal of Bromophenols from Wastewater by Sorption
(University of Waterloo, 2018-09-20)Poly(ether-block-amide) copolymer (PEBA) was used as an adsorbent for sorptive removal of bromophenols, particularly 4-bromophenol (BP), 2,6-dibromophenol (DBP), and 2,4,6-tribromophenol (TBP) from wastewater. Batch sorption ... -
Removal of Enteric Viruses By Ultrafiltration Membranes
(University of Waterloo, 2011-08-29)Application of low pressure membranes in drinking water treatment, including both microfiltration (MF) and ultrafiltration (UF), have witnessed a rapid increase in the past decades. Low pressure membranes are considered a ... -
Study of Ion and Solvent Transport through Graphene Oxide Membranes
(University of Waterloo, 2017-01-10)Filtration membranes are required to be thin, robust, energy efficient, and accurate on selectivity. Graphene oxide (GO) is believed to be a potential next generation material for industrial membrane applications because ... -
A Study of the Mobility of Silver Ions in Chitosan Membranes
(University of Waterloo, 2007-06-14)Chitosan membrane has found applications in biomedical, wastewater treatment, and petrochemical fields that involve the use of silver ions (Ag+). However, mobility of Ag+ in chitosan membranes has seldom been studied. ...
