Development of proxy reservoir models for geological carbon storage

The project’s aims are to conduct research on geological carbon storage from the perspective of dynamic analysis and process systems engineering, looking in particular at the dynamics between the wellhead and the CO2 storage reservoir. The main objective is to achieve closed loop operation and management of the reservoir with respect to CO2 sequestration and storage, along with enhanced oil recovery in cases where the reservoir is not fully depleted.

Miniaturized Power Supplies: Research on Micro-fluidic Rechargeable Batteries

With the fast growth in the Micro-Electromechanical System (MEMS) market, there is also growing need for miniaturized power sources. MEMS devices are beginning to make significant contributions in new subjects, including Lab-on-Chips (LOC) and other micro-fluidic devices, wireless communications, sensors, and optics. In all these technologies, electric power is a vital issue for the further development of the MEMS field.

Tailoring Rheological Properties of RigidReclaim™ Resin Streams

The RigidReclaim™ technology under development by Entropex is an innovative process which converts a comingled, contaminated Mixed Rigid waste stream into highly pure, commercially valuable resins. The non-uniform natures of the plastic waste pose a significant challenge to satisfy the quality requirements for high-value applications. This project is a critical component of the RigidReclaim™ technology and it aims at tailoring the rheological properties of the recovered resin streams comparable to those of virgin resins with reliable novel chemical additives.

Fabrication of the 3rd generation photovoltaics using TiO2 nanotubes and quantum dots

Due to depleting oil supplies and the global climate change we are compelled to seek alternative sources to supply our growing energy demand. Among green energy technologies, utilizing solar energy is the only way to address that problem, and tapping into this vast quantity of energy represents a grand challenge of scientific research and engineering. Current silicon technologies have thus far experienced limited deployment, primarily due to material costs. Developing novel methods of capturing solar energy is required.

New tools to study enzyme penetration and activity dynamics within wood cell walls

The main challenges in bioconversion of lignocellulose arise from our limited understanding of the heterogeneous chemistry of the substrate and poor accessibility of enzymes within dense wood cell walls. It is clear that our limited appreciation of enzyme penetration into cell walls and catalysis dynamics is partly due to the constraints of the techniques employed previously. Unlike these other studies, which addressed such questions by examining model substrates, I propose to examine and develop new tools for use on complex solid wood substrates.

Sustainable Development through the Effective Production and Use of Bio-Fuels and Integrated Bio-Refineries

The project concentrates on developing a holistic approach to integrate bio-refinery with multiple feedstocks. The proposal is directed towards the use of all types of renewable raw materials except food. The project examines the possibility of retrofitting an existing petroleum refinery and petro-chemical complex into integrated bio-refinery to emphasize the utilization of existing infrastructure for bio-fuels; bio-products and direct bio-energy production.

Coprocessing of Biomass and Heavy Oils (Bio-Economy and Clean Technologies)

Pyrolysis uses high temperatures, in the absence of oxygen, to crack long and complex molecures into smaller molecules.  It has been successfully and separately applied to both (a) heavy oils, to produce lighter liquid fractions and solid coke byproduct in conventional oil refineries, and to (b) biomass, to convert solid residues into liquid bio-oils.  Pyrolytic cracking generates highly reactive radical fragments, which then recombine into different chemical species.  The proposed research consists in the development of a new technology for the simultaneous co-processing of biomass and hea

Optimizing adjacent technologies for physical and/or functional integration with UV-based technologies

This research project is directed towards the assessment and development of technologies that will complement the UV technologies provided by Trojan Technologies for water/wastewater treatment.  A novel liquid-solid circulating fluidized bed bioreactor (CFBBR) developed at the University of Western Ontario in collaboration with Trojan Technologies has generated a wide interest for commercial application for biological nutrient removal (BNR) from wastewater.  A generic high solids retention time in the CFBBR primarily due to the attached biomass would enhance degradation/removal of the emerg

Dry powder coating of solid pharmaceutical dosages

Solid pharmaceutical dosage forms such as tablets and beads used in capsules are currently coated by liquid coating technology, which incurs high environmental risk and high capital and operation costs. Prof. Zhu's research group has developed an ultratine powder coating technology for the auto industry. Our previous studies have shown that the same technology can also be extended for pharmaceutical solid dosage forms. So far, first success in the new coating technology has been achieved and several coating systems have been developed using acceptable formulations.

Developing an on-line fluidization analysis probe

The main objective of this research is to develop an on-line fluidization analysis probe to be applied on a commercial fluidized bed. This project will focus on a combination of pressure differential and fiber optic reflection probes. Key objectives will be to establish a lab probe with dual fiberoptic and high frequency pressure readings.  Emphasis will be on establishing signal analysis for both fiber optics and pressure and then use the combined probe in a lab environment.
