Characterization and Improvement of Interfacial Properties of Cathode Materials forRechargeable Hybrid Aqueous Batteries

A new aqueous rechargeable battery combining an intercalation cathode with a metal anode has been developed recently. The energy density for a prototype battery is comparable or superior to commercial 2 V rechargeable batteries. There is a need to further improve the cycle performance and to reduce self-discharge effects of this battery. In this proposed research, novel surface improvements will be applied to the cathode material to improve the overall electrochemical performance of the battery and to improve the stability of the cathode material.

Coherent Control of High-Q Devices

Research into understanding and controlling microscopic quantum mechanical phenomena has led to revolutionary new quantum devices, including quantum sensors and actuators that have unprecedented levels of sensitivity, efficiency, and functionality for a wide variety of tasks. A particularly compelling example is high quality factor (high-Q) superconducting resonators for magnetic resonance. These new devices will be substantially more sensitive than current devices in widespread use.

Development of Novel Methods for the Automated Extraction of Lipid-Soluble Compounds Year One

Current analytical methods for the extraction of lipid-soluble compounds (fatty acids, cholesterol, antibiotics, pesticides, vitamins) are costly and time-consuming. Recently, we have assessed a novel patent-pending “kit” method for extracting fatty acids and cholesterol from food and tissues with great success. We propose to continue testing this method for extraction of lipid-soluble vitamins, pesticides and antibiotics for the continued sale of kits to potential research laboratories.

Advanced Simulation Methods for a Next Generation Computational Fluid Dynamics Solver Year One

Computational Fluid Dynamics (CFD) is a branch of fluid mechanics that is focused on using numerical methods to solve and analyze practical engineering problems involving fluid flow. The purpose of the proposed research project is to develop novel simulation methods directed at applications in sensitivity analysis and design optimization. Sensitivity and optimization studies are becoming more common as engineers are challenged to determine optimal operating configurations for their designs.

Transdermal Alcohol Detection System through Measurement of Capacitance Change in a MEMS Device Year One

The proposed research develops a transdermal alcohol detection system. The system is comprised of an array of polymer based MEMS sensors and a sensor measurement circuit. The system analyzes gases exuded from the skin - the gases are chemical mixtures that may (or may not) contain ethanol. No known polymers respond only to ethanol; however, each polymer in the array creates a unique response to the presence of ethanol. When examined together - like a series of simultaneous equations - sensor responses accurately indicate the presence of ethanol.

Development of a smartphone-based sensor system to assess everyday movement, speech, and sleep for stroke recovery Year One

Following a stroke, the rehabilitation gains achieved in intensive therapy are often lost without sustained follow-up. The long-term objective of the project is to extend the reach of the health team (physicians, therapi sts, caregivers) following hospital discharge to continue therapy using mobile devices. As a first step, the objectives of the planned project are to:

1) develop clinically meaningful metrics related to the quantity and quality of everyday movement, speech, and sleep from body-worn sensor data,

2) to design and fabricate system prototypes for testing, and

Preparation of commercial TPVs from Devulcanized Rubber Year Two

This research project intends to further expand the use of the recycled rubber (also referred as devulcanized rubber) prepared from waste tires to reduce the threat caused by the increasing number of scrap tires. Due to relatively inferior properties, the devulcanized rubber cannot be used by itself. Hence, the research focuses on blending the devuclanized rubber with cheaply available plastics. A patented technology has been developed in our lab that leads to preparation of high quality devulcanized rubber.

Determining the timespan and ecological conditions necessary for afforested environments to support older-growth understorey communities Year Two

Mineral aggregate production is essential to Canada’s economy and infrastructure but environmental concerns threaten to impede this until ecological impacts are shown to be mitigated by off-site replication of affected ecosystems including heritage hardwood forests. A large-scale comparative study was recently initiated to determine whether conventional forestry can produce plantations that are ecologically equivalent to natural forests.
