Symbolic Finite Element Analysis for Parametric Studies

Johnstone R.W., Shimizu T., Parameswaran M., Simon Fraser University, CA

In our paper, we will present a method of performing finite element analysis using a symbolic kernel. The representation of numbers used in analysis is symbolic expressions instead of floating point numbers. Unlike standard finite [...]

Fabrication and Characterization of 3D Square Spiral Photonic Crystals

Jensen M.O., Summers M.A., Brett M.J., University of Alberta, CA

Three-dimensional photonic crystals can be fabricated using the glancing angle thin film deposition technique (GLAD). These nanostructured thin films consist of a periodic array of micrometer-sized silicon square spirals, as proposed by O. Toader and [...]

A Comprehensive Kinetic Model for Wet Oxidation of Silicon Germanium Alloys

Rabie M.A., Haddara Y.M., Carette J., McMaster University, CA

Our objective is to study the kinetics of SiGe oxidation with a view to studying factors that would improve the quality of the oxide. We propose a model based on the simultaneous oxidation of both [...]

Modeling of Germanium/Silicon Interdiffusion in Silicon/Silicon Germanium/Silicon Single Quantum Well Structures

Hasanuzzaman M., Haddara Y.M., McMaster University, CA

Intermixing at heterointerfaces and the broadening of the SiGe layer in a Si/SiGe/Si single quantum well (SQW) structure can be detrimental to device performance. Thus it is important to develop predictive models for interdiffusion phenomena [...]

Nano Architecture MEA for Next Generation Fuel Cell

Schneider J., Picard G., Seye M-F, Nanometrix Inc., CA

The Schneider-Picard (SP) method for industrial monolayer and ultra-thin film deposition has shown a great effectiveness for the production with nano scale architecture for fuel cell Membrane Electrode Assembly (MEA). Today, MEA's are built in [...]

Reflow Microfabrication for Refractive Optical Components: Process and Materials

Johnstone R.W., Parameswaran M., Simon Fraser University, CA

Our paper will describe a new method of fabricating refractive optical components for free-space micro-optical systems. The seminal paper on this topic was Pister et al [1], in which hinges were used to demonstrate several [...]

A Novel Process for Flexible Nano Electronic Web Production

Picard G., Schneider J., Seye M-F, Nanometrix Inc., CA

Nanometrix presents a new concept to make monolayers and ultra-thin films for nano electronic web processing. The novel method was designed ex novo to match with today's industrial production line standards. In this process, the [...]

Antimicrobial Fabrics Coated with Nano-Sized Silver Salt Crystals

Tessier D., Radu I., Filteau M., Center for Textile Technologies, CA

Antimicrobial fabrics find many technical applications in medical, hygiene, protection, sport, and industrial markets. However, antimicrobial fabrics differ in biocidal performance and durability. For example, such fabrics are used in wound dressings or bio-hazard protective [...]

Evolution of Streaming Potential in a Finite Length Microchannel

Mansouri A., Bhattacharjee S., Kwok D.Y., Kostiuk L.W., University of Alberta, CA

Pressure-driven-flow in a microchannel with charged solid surfaces induces streaming current and streaming potential. Review of the literature, reveals that most of the studies on the microchannels are either for steady state solution or infinite [...]

Electrochemical Detection of Single-Nucleotide Mismatches: Application of M-DNA

Abu-Irhayem E., Long Y-T., Sutherland T., Li C-Z, Kraatz H-B, Lee J.S., University of Saskatchewan, CA

The detection of a single-nucleotide mismatch in a 20 base pair duplex DNA, using Electrochemical Impedance Spectroscopy, is presented. Mismatched DNA monolayers on Au electrodes were studied as normal duplex DNA (B-DNA) and after conversion [...]
