Electrical characterization of graphene-based composites

Blending carbonaceous materials with thermoplastic materials can lead to a significant improvement of the resulting electrical, mechanical, thermal, and gas barrier properties compared with the unfilled polymer. Graphene, the name given to a material consisting of two-dimension layers of carbon atoms arranged in a hexagonal lattice, has extraordinary properties which make possible to produce a new class of polymer nanocomposites with significantly improved properties.

Real-time Quantitative Analysis of Cannabinoids in Cannabis

The medical marijuana industry has attracted significant attention recently due to its impending legalization in Canada in the coming year. Along with legalization comes the need for accurate and dependable characterization of the components in the product that is to be consumed by the end user. Keystone Labs is a certified cannabis analysis lab with a growing client base. Hence, they are looking to increase their market share by developing a home testing kit that can be used by growers to monitor the plant's chemical composition as it matures.

Low-damage deposition of transparent conductive oxides as top contacts for transparent organic light emitting diodes

Organic light emitting diodes, or ‘OLEDs’ have become a common technology in everyday displays such as mobile phones, laptops, and televisions. These types of devices rely on an OLED structure that uses ‘bottom-emission’, meaning that the top of the device consists of a non-transparent backplane, and the light and colours generated in the device are emitted through the transparent, bottom side of the device.

Synthesis of diamond and diamond-like films

This project is geared towards the development of a cost-effective method to fabricate thin films of carbon materials, such as diamond. The idea is to use solution-based methods coupled to electrochemistry to produce the films. Avenues for the deposition of the film on surfaces of arbitrary shapes will also be explored.

Development of a nanonewton force sensor for in-situ characterization of nanomaterials

Nanomaterials are the fundamental building blocks of nanotechnology. Despite the advances in nanomaterial synthesis, no reliable technique exists to characterize their physical properties. The key challenge lies with the lack of accurate force and displacement feedback. To tackle the problem, leading researchers from University of Toronto and from Toronto Nano Instrumentation (TNI) Inc. are working together to develop the next generation technology for nanomaterial testing.

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.
