New Type of High Sensitive Detection of Particles Based on DeFET

Ibrahim M.F., Elsayed F., Ghallab Y.H., Badawy W., University of Calgary, CA

This research work presents a new implementation of the CMOS electric-field sensor, titled as Differential Electric Field Sensitive Field Effect Transistor (DeFET). The DeFET is successfully used in detection of small partials and it is [...]

Effects-Based Risk Assessment of Emerging and Existing Nanomaterials

Chan-Remillard S., Kapustka L., Goudey S., Golder Associates Ltd. & HydroQual Laboratories Ltd., CA

Nanotechnology has been compared to the industrial revolution in its scope of applications and ability to dramatically transform new and existing technologies. Nanotechnology is a quickly emerging field where the toxicological effects on human and [...]

Improvements in biological hydrogen production by microbial fermentations

Hallenbeck P.C., Sabourin-Provost G., Université de Montréal, CA

A series of physiological and genetic manipulations that improve hydrogen yields are described. The possible improvement of yields and rates through the heterologous expression of various hydrogenases will be discussed. In initial photofermentation experiments we [...]

Complete Microbiological Fuel Cell: A Photosynthetic Cathode Coupled to a Fermentative Anode

Powell E.E., Bolster J.C., Hill G.A., Evitts R.W., University of Saskatchewan, CA

A completely biological microbial fuel cell (MFC), using photosynthetic growth at the cathode and yeast fermentation at the anode, has been developed and operated successfully for the first time. The photosynthetic culture, Chlorella vulgaris, was [...]

Field Emission Properties of Carbon Nanotube Arrays with Defects and Impurities

Roy Mahapatra D., Sinha N., Melnik R., Yeow J.T.W., University of Waterloo, CA

Field emission from carbon nanotubes (CNTs) in the form of arrays or thin films give rise to several strongly correlated process of electromechanical interaction and degradation. Such processes are mainly due to (1) electron-phonon interaction [...]

Modeling and simulation of a monolithic self-actuated microsystem for fluid sampling and drug delivery

Zhang P., Jullien G.A., University of Calgary, CA

A novel MEMS-based microsystem including microneedle array with a self-actuated structure for fluid sampling and drug delivery is modeled, designed and simulated. The self-actuating mechanism and the microneedle array are able to be fabricated on [...]
