Initial Investigation of the Synthesis andCharacterization of Novel Core-Shell Pt Catalysts

Presently, platinum (Pt) nanoparticles are required to catalyze the desired redox reactions at the anode and cathode of proton exchange membrane fuel cells (PEMFCs). The high cost of this precious metal catalyst remains a barrier to the wide spread commercialization of PEMFCs, particularly for automotive applications. In an effort to reduce the Pt loading in PEMFCs, this research project is focused on the design of novel catalysts which consist of depositing a 1-2 monolayer “shell” of Pt onto a less expensive metal which acts as a “core”.

Scale-up and Optimization of 3D Gel Dosimeters Year Two

The project aims at designing and manufacturing a series of products (gel dosimeters) that can be used for quality assurance of the radiation treatment of cancer: before treatment, a gel dosimeter is irradiated instead of the patient, and its colour changes to show the pattern of the delivered radiation dose. Then that colour change is imaged in a scanner and compared against the planned treatment. Any significant differences between the planned and delivered dose can be fixed before the patient is subjected to the radiation.

Glycerol conversion to value added products: 1, 3-propanediol (1,3-PDO) and Acrylic Acid(AA)

This project is aimed to develop novel catalytic system and process for production of valuable chemicals such as 1,3-propanediol and acrylic acid from glycerol. Glycerol is a byproduct of biodiesel production (10 kg of biodiesel yields 1 kg of glycerol). The production of biodiesel is expected to grow almost 7-fold from 3.8 MMTPA in 2005 to about 25 MMTPA in 2015. This increase in demand for biodiesel in the world market has increased the quantity of glycerol generated.

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.

Action spectra characteristic of typical and potentially new challenge organisms used in polychromatic UV reactor validation Year One

Trojan Technologies provides UV-based technologies for water, wastewater and reuse wastewater treatment. This proposal is directed towards optimizing and developing the validation protocols for UV systems provided by Trojan. The study results will expand Trojan's ability to provide more holistic and sustainable reactors for water/wastewater treatment as well as expand the polychromatic UV market.

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.

Development and Validation of Defined Biomaterial Surfaces to Grow Stem Cells Suitable for Regenerative Medicine Year Two

The proposed research aims to develop and validate surfaces that have no components of animal origin for the growth of stem cells. Materials not of animal origin are required for the growth of stem cells if they are to be used clinically to treat disease and/or injury. Initially, surfaces already developed and designed by the fellow during his Ph.D. will undergo testing for stem cell growth. Concurrently, additional surfaces will be developed with stem cell niches identified by StemCell Surfaces.

Refining of Kisolite Clay for Cosmetic and Phamaceutical Applications

There are four main objectives for the proposed project: 

 

(1) To investigate three techniques of aiding the wet screening process including: (a) inclined screening combined with water jets, (b) sonication, and (c) a combination of those two techniques, to find optimum operating conditions for each technique and allow them to be evaluated and compared.

(2) To implement the most suitable technique on the industrial scale and establish its optimum operating conditions.

Research And Development of Heat Flowable High-Strength Bioabsorbable Bone Adhesive

The primary project objective of this proposal is to evaluate company’s absorbable polymeric (PCL/PLLA) performance as the heat flowable bone repair adhesive materials. The expected overall project outcome is a unified surgical delivery tool and implantable adhesive that provides the customers/users (surgeons/patients/hospitals) of this device a surgical repair product. Materials and Methodology: Material Description: The UMass patent covers a blend of two well-known absorbable materials Polycaprolactone (PCL) and poly(L-lactide) (PLLA).
