Additive Effects on Melt-State Modification of Commodity Polyolefins
(2016-04-04)In this work, melt-state peroxide mediated crosslinking of butyl rubber (IIR) and linear low density polyethylene (LLDPE) was used to determine additive effects, as well as the effect of higher isoprene content on the ... -
Advanced Applications of Miniemulsion Technology
(2010-04-19)Miniemulsion technology is attracting increasing interest for the preparation of nano-size particles. However, the barrier to industrialising miniemulsion-based products is the lack of an energy efficient and scalable ... -
Alginate Microparticles Produced by Spray Drying for Oral Insulin Delivery
(2009-09-29)The aim of this study was to prepare biologically active insulin-loaded alginate microparticles by spray drying. Particles were produced from three alginate feed concentrations of 1, 1.5 and 2% w/v, with respective insulin ... -
Amphiphilic Diblock Copolymers as Stabilizers in Emulsion Polymerization
Emulsion polymerizations, used to produce many commodity materials, require stabilizing agents to prevent phase separation. Incorporation of these stabilizers in the final polymer may have negative effects on product ... -
Application of a Methanotrophic Immobilized Soil Bioreactor to Trichloroethylene Degradation
(2008-09-30)Trichloroethylene (TCE) is a major groundwater contaminant and is a cause of serious health concern. Methanotrophic TCE degradation is very promising compared with other treatments. Methanotrophs produce methane monooxygenases ... -
The Application of Monte Carlo Combined Methods For Modeling of Polymerization Kinetics
(2014-09-30)The advantages and disadvantages of the two major categories of numerical methods, deterministic and stochastic approaches, in polymer reaction engineering are discussed. Combinations of methods are suggested in order to ... -
Aqueous Cu(0) Mediated Reversible Deactivation Radical Polymerization of 2-Hydroxyethyl Acrylate
(2015-08-31)Reversible deactivation radical polymerization (RDRP) of 2-hydroxyethyl acrylate in D2O was studied using Cu(0) wire and Me6TREN, with different target chain lengths (TCL), amount of initial Cu(II)Br2, and the addition ... -
Assessing the biocompatibility of oligomers and amine-functionalized polymers for use in two-phase partitioning bioreactors
(2015-10-29)Two-phase partitioning bioreactors (TPPBs) are a bioprocessing tool that limits inhibition of cell growth by toxic compounds in bioreactors by utilizing an immiscible secondary phase to sequester compounds that inhibit ... -
Assessment of a Regenerative Therapy Strategy for Chondral Defects in Articular Cartilage
(2015-09-18)Osteoarthritis is one of the leading causes of disability in adults over the age of 40 years, and there is currently no curative measure for the disease. As a result, there is a critical need for a strategy that can promote ... -
Assessment of Photocatalytic Performance of Aluminium-Supported Titanium Dioxide Thin Films Produced by Flame Assisted Chemical Vapour Deposition
(2015-12-16)Titanium dioxide films were deposited on aluminum by flame assisted chemical vapour deposition. The photocatalytic performance of these films when the air flow rate to the flame and thickness of silicon oxides under-layer ... -
