High Cell Density Culivation of Methylosinus Trichosporium OB3b
(2008-09-04)Methylosinus trichosporium OB3b is a wild type, obligate methanotroph that grows only on one-carbon compounds and, in the absence of copper, produces high levels of soluble methane monooxygenase (sMMO) to metabolize methane ... -
Hydrogen bonding in radical copolymerization: A kinetic investigation under industrially relevant conditions
Radical solution polymerization is a common method to produce a variety of plastics and coatings. Particularly in the automotive industry, large scale semi-batch operations are used to (co)polymerize monomers of the styrenic, ... -
Hydrolytically Degradable Cationic Flocculants For Improved Water Recovery From Mature Fine Tailings
Oil sands mining operations in Canada produce large volumes of waste tailings that are difficult to dewater using commercial polyacrylamide-based flocculants. Recently, a novel hydrolytically-degradable polymer was synthesized ... -
Imidazolium Ionomer Derivatives of Isobutylene-Rich Elastomers: Thermosets, Emulsions, Filler Composites and Clay Nanocomposites
(2013-12-11)Ionomers are valued for their exceptional physical properties, antimicrobial activity and superior adhesion to high surface energy solids and polymer blend components. Carboxylate, or sulfonate derivatives, of ethylene-rich ... -
Imidazolium Ionomer Derivatives of Poly(isobutylene-co-isoprene)
(2011-02-03)The allylic bromide functionality in brominated poly(isoprene-co-isobutylene) rubber (BIIR) reacted readily to nucleophilic substitution by imidazole-derivatives. When reacted with the rubber, alkylimidazoles formed a ... -
Improved recipes for leuco-crystal violet micelle gel dosimeters
An optimized recipe for a radiochromic micelle (RM) leuco-crystal violet (LCV) gel dosimeter was proposed using full-factorial designed experiments and model-based optimization. Linear regression models were used to optimize ... -
Improved Recipes for Polymer Gel Dosimeters Containing N-Isopropylacrylamide
(2008-12-17)Experimental studies were undertaken to improve the radiation dose response and ease of manufacture of polymer gel dosimeters that use N-isopropyl acrylamide (NIPAM) as the monomer. An alternative carageenan gelling agent ... -
Improvement of Biofuel Fermentation Processes With Use of Poly(vinyldodecylimidazolium bromide) for In-situ Product Removal
The production of biofuels through fermentation has become increasingly important due to the need for sustainable energy sources. The fermentation processes of ethanol and n-butanol, by Saccharomyces cerevisiae and ... -
In Vitro Assessment of Bone and Cartilage Stimulating Peptides
(2016-04-11)Spinal fusion is an effective and one of the most commonly used surgeries to treat intervertebral disc degeneration (IDD) related low back pain. However, non-fusion still occurs in about 10-15% of the clinical cases. The ... -
In Vitro Simulation of In Vivo Performance of Oral Dosed Nanoparticulate Insulin
(2013-08-26)The aim of this study was to evaluate the factors, which affect insulin release and stability in simulated gastrointestinal fluid that ultimately will reduce the bioavailability of insulin in a nanoparticulate oral delivery ... -
Indirect Co-culture of Human Adipose-Derived Stem Cells and Nucleus Pulposus Cells for Intervertebral Disc Regeneration Using Peptide-Conjugated Hydrogels
(2015-11-06)Intervertebral disc degeneration (IVDD) is a main cause of chronic low back pain, which results in significant economic loss to society and compromised life quality of patients. Traditional treatments of IVDD include ... -
