Controlling the Active Center of Gold Nanoreactors by Mediating the Metal-Polymer Interaction

Shah V., Malardier-Jugroot C., Jugroot M., Malardier-Jugroot C., Royal Military College of Canada, CA

Nanomaterials have gained large interest from the scientific community due to the fact that materials at nanoscale exhibit unique electronic, magnetic and optical properties when compared to the bulk. The main advantage associated with nanostructures [...]

Embedded fiber optic sensors for battery performance monitoring in Lithium ion battery cells

Alemohammad H., Ghannoum A., Zdravkova L., Iyer K., Nieva P., Yu A., Khajepour A., Nieva P., Yu A., Khajepour A., University of Waterloo, CA

This paper is focused on the development of an embedded fiber optic sensor for monitoring the performance of Lithium ion battery (LIB) cells. The number of LIB cells are proliferating mainly due to the global [...]

Fabrication of highly ordered vertical GaAs nanowires by inductively coupled plasma etching and their modal analysis

Dhindsa N., Chia A., Boulanger J., Khodadad I., LaPierre R., Walia J., Saini S., University of Waterloo, CA

We present highly ordered vertical gallium arsenide (GaAs) nanowires fabricated by dry etching using various metal mask combinations. A great control on the length, diameter, pitch and facet tapering of the nanowires was achieved. Diameters [...]

A new at-line quality and process control technology for real-time testing of viscoelastic changes in dairy and food products

Strandman S., Henni A.H., Schmitt C., Rheolution Inc., CA

Currently, few methods allow monitoring the viscoelastic properties of food products in production environments for process and quality control. In addition, there is a pressing need for a testing instrument that: is affordable and easy [...]

The use of Ag5IO6 as an antimicrobial agent in wound dressing against microbial biofilms

Incani V., Omar A., Prosperi-Porta G., Nadworny P., Innovotech Inc, CA

This work explores the unique antibiofilm activity of pentasilver hexaoxoiodate (Ag5IO6). Impregnated wound dressings with Ag5IO6 were designed and their antibiofilm activity was compared with various commercially available silver and non silver-containing dressings. Ag5IO6-wound dressings [...]

Synthesis of a pH Responsive Polymeric Drug Delivery – tailoring functionalization for effective delivery

Li X., Malardier-Jugroot C., Royal Military College of Canada, CA

Poly (styrene-alt-maleic anhydride), PSMA, is an amphiphilic alternating copolymer presenting a pH responsible self-assembly into nanotubes in aqueous solution. Its self-assembled structure with a 2nm hydrophobic inner diameter is stable in neutral pH solution, but [...]

Technical and Economical Feasibility of Pyrolysis of Kraft Lignin

Farag S., Chaouki J., École Polytechnique de Montréal, CA

This research project discusses the technical and economical feasibility of converting kraft lignin to value-added chemicals. Two pyrolysis techniques were implemented: conventional pyrolysis using classical heating and microwave pyrolysis using electromagnetic irradiation. The product distribution [...]

Field Application of Nanoparticle-Based Invert Emulsion Drilling Fluids

Borisov A., Husein M., Hareland G., nFluids, CA

Abstract. Application of nanotechnology in drilling fluids for the oil and gas industry has been a focus of several recent studies (Zakaria et al. 2012; Contreras et al., 2014). Zakaria et al. (2012) developed a [...]

Biomimetic Nanoreactors via in situ Synthesis of Atomically-Thin Gold Sheets and Platinum Nanoclusters

McTaggart M., Malardier-Jugroot C., Jugroot M., Malardier-Jugroot C., Royal Military College of Canada, CA

We present the synthesis and activity of broadly stable polymer-metal nanoreactors capable of confinement-enhanced catalysis. Poly(styrene-alt-maleic acid), SMA, is known to self-assemble in water into highly organized supramolecular nanostructures containing confined polar and non-polar reaction [...]

Concern-Driven Approach to human health risk assessment of nanomaterials: A Nanoparticle Screening Assessment Framework

Bernatchez S., Afghan A., Lai D., Sayre P., Hill M., New Substances Assessment and Control Bureau, CA

The framework proposed here was developed under the Canada-US Regulatory Cooperation Council (RCC) Nanotechnology Initiative and represents a concern-driven approach to focus human health concerns and additional testing requirements for nanoparticles based on their physical [...]
