Novel Elastomeric Chitin Nanocomposites for Coatings and Adhesives

The proposed project is a characterization study on chitin nanowhisker nanocomposites. Chitin nanowhiskers are derived from chitin, a naturally occurring biopolymer found in arthropod exoskeletons, and offer great potential for reinforcement and property enhancement once blended with typical engineering plastic matrices. Compared to traditional inorganic fillers such as carbon nanotubes and graphene, chitin nanowhiskers are biocompatible and biodegradable, exhibiting comparable property improvements with none of the downsides of the inorganic materials (i.e. biohazardous, toxic).

Development and characterization of polyester/graphene coatings

Environmental aging is responsible for many industrial failures. Using a protective coating is one of the most common and also efficient methods to protect material surfaces against environmental attack, and consequently extend their life. For modern coatings used for industrial applications, besides high chemical stability and good adhesion, new functionalities such electrical conductivity or anti-static properties are desired. For example, for development of transportation and electronic technologies, a low cost conductive coating with good physical properties is required.

Validation and Development of Clinically Relevant Copper Complexes for the Treatment of Bacterial Infections

Nearly 70% of all drug candidates are not pursued for pharmaceutical development because they cannot be dissolved into solutions appropriate for human use. Cuprous Pharmaceuticals Inc. (CPI) recently discovered that some of these drugs could be dissolved in the presence of certain metal ions. Furthermore, a number of metal-drug complexes are more therapeutically active than their metalfree counterpart.

Atomic Layer Deposition Tool – Testing and Process Development

Currently, no Canadian-based companies are involved in the manufacturing of state-of-the-art research tools for atomic layer deposition (ALD). Angstrom Engineering is a leading manufacturer of similar technologies – physical vapour deposition and chemical vapour deposition – and have identified an opportunity to produce the first ALD research tool manufactured entirely in Canada. ALD is a vapour phase technique that offers sequential, self-limiting surface reactions to deposit thin films with exceptional control over thickness and composition, as well as conformality and uniformity.

Monodisperse PhytoSpherix Nanoparticles Modified for Key Applications in Personal Care, Food and Nutraceuticals

Our previous work has shown the promise of monodisperse phytoglycogen for many applications. However, these experiments only scratch the surface of potential uses since the chemistry of the particles (as extracted) is fixed. Nanoparticles offer very high surface areas, and glucose units are easily modifiable, thus there exist a multitude of ways to chemically modify the surface to produce a wide variety of new material properties.

Remediation of Contaminated Soil and Groundwater using Nanotechn

In recent years, the oil and gas industry has prioritized the remediation of residual and historical soil and groundwater contamination due In part to increased public awareness and media attention on the subject. As a result, in an effort to demonstrate social accountability and environmental sustainability, there has been a significant increase In the exploration and implementation of cost-effective and environmentally-friendly approaches for remediation of contaminated sites.

Metamaterial in Solar Energy Harvesting Devices

Solar energy is one of the best sources of environmentally friendly reliable energy. Metamaterials is one of the subjects of nanotechnology, which applies scientific and engineering principles to make and utilize very small things— things at the nanometer scale, where unique phenomena enable novel applications. How to improve the efficiency and reduce the cost of power collected by crystalline silicon solar cells with Metamaterials is a subject of great interest and also the objective of this project.

Radiation Modulated Nanomedicine Delivery

The current survival times for breast cancer patients with brain metastasis range from 2 to 16 months suggesting a strong need for improvements in their therapeutic care. Although radiation therapy is the standard of care for these patients, combination with chemotherapy has demonstrated promising therapeutic benefits. The hypothesis of this research program is based on the belief that optimizing combination of radiation and chemotherapy has the potential to significantly improve the treatment outcome for patients with breast cancers that have metastasized to the brain.

Optimization and validation of carbon nanofiber catalyst supports in fuel cell stack

Motivated by the urgent need for clean and sustainable source of energy we propose to develop structurally and chemically controllable fuel cell catalyst layers based on ultrafine nanocomposite carbon fibre catalyst support. Manufacturing parameters will be controlled and optimized to investigate the effect of microstructure on key performance factors. Ultimately, the knowledge gained from this study will pave the way to building more efficient fuel cells. Current phase of the project involves validating our design by in-situ testing.

Structural colors on polymers by femtosecond laser irradiation

Most colors in nature are due to the presence of pigments or dyes. Artificial colors on different materials are produced by incorporating dyes in them. However, the brightest colors in nature, e.g. the colors of butterfly wings and peacock feathers, are generated because of the micro/nano-features on their surface. Unlike the added dyes or pigments in a material, the colors produced by surface features, also called structural colors, do not fade with sunshine and this colors are non-toxic. Laser irradiation can create structural colors on metals by an easy one-step process.
