PARK AND VEVA REILLY DISTINGUISHED SEMINAR - “Genetic and Metabolic Engineering of Clostridium pasteurianum for Production of Butanol as a Renewable Biofuel” by Michael Pyne, PhD, Post-Doctoral Fellow, University of Waterloo

(Please be advised that signing a NDA will be required for attending this seminar)

ABSTRACT:  The Acetone-Butanol-Ethanol (ABE) fermentation by anaerobic bacteria from the genus Clostridium was one of the first large-scale industrial bioprocesses, operating globally for the production of acetone during the first half of the 20th Century. Feedstock and product recovery costs prevented the ABE process from remaining profitable and acetone production was overtaken by the developing petroleum industry.

Seminar - “Size Matters: Developing Design Rules to Engineer Nanoparticles for Solid Tumour Targeting" by Edward A Sykes, Institute of Biomaterials and Biomedical Engineering, University of Toronto

ABSTRACT:   Nanotechnology offers highly customizable platforms for producing minimally invasive and programmable strategies to diagnose and treat cancer. Advances in this field have demonstrated that nanoparticles can enhance specificity of anti-cancer agents, respond to tumour-specific cues, and direct the visualization of biological targets in vivo.

Seminar - “Biochemical Control of Phosphate Mineral Saturation: A Proposal for Polyphosphates” by Sidney Omelon, Assistant Professor, Chemical Engineering, University of Ottawa

ABSTRACT:  The rigidity of our skeleton is due to reinforcement with nano-sized minerals of biological apatite.  Theories of skeletal apatite nucleation include initiation by the organic matrix (collagen and non-collagenous proteins), and increasing the phosphate concentration by hydrolysis of phosphoric acid monoesters.  An enzyme that has been attributed to skeletal mineralization - tissue-nonspecific alkaline phosphatase (TNAP) - is known to increase inorganic phosphate concentration by catalyzing phosphoric acid monoester hydrolysis.  However, the substrate for TNAP in

Seminar - “Optimal Molecular Design of Ionic Liquids for CO2 Capture” by Antonio Flores-Tlacuahuac, Professor, Department of Engineering and Chemical Sciences, Universidad Iberoamericana, Mexico City, Mexico

ABSTRACT:  We propose a processing alternative for replacing the traditional and environmentally dangerous solvents (as monoethanolamine, diethanolamine) in the process of CO2 capture. We use a computer aided molecular design (CAMD) methodology for exploring the use of ionic liquids (ILs) as solvents for CO2 capture. The CAMD formulation is solved as a mixed-integer nonlinear programming (MINLP) problem, the objective is to obtain an optimal molecular structure of an ionic liquid for CO2 capture from a post-combustion (PC) gas stream (GS).

Seminar - “Surface Modification of Polymeric Biomaterials to Improve Interfacial Interactions” by Kyla Sask, PhD

ABSTRACT:  Polymers and other materials that are used in contact with biological fluids such as blood are prone to protein adsorption and cell interactions. A protein layer quickly forms at the surface of the material and can influence the subsequent adhesion of platelets, leukocytes, other cells and microbes. For medical devices this can lead to numerous complications including coagulation, thrombosis (blood clotting) and infection, among others.

Seminar - "Understanding Coupled Mechanical-Chemical Degradation Mechanisms for Improving the Performance and Durability of Lithium Ion Batteries" by Yang-Tse Cheng, University of Kentucky

ABSTRACT:  Advanced lithium ion battery electrodes experience large volume changes caused by concentration changes within the host particles during charging and discharging. Electrode failure, in the form of fracture or decrepitation, can occur as a result of repeated volume changes. In this presentation, we will provide an overview of our recent work on understanding the evolution of concentration, stress, and strain energy within a spherically- or cylindrically-shaped electrode element under various charging-discharging conditions.
