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.

Statistical analysis and interpretation of metabolite profiling results

Data analysis and interpretation is a critical step in metabolomics. In metabolomics studies, large amounts of data must be evaluated by appropriate analytical tools in order to transform data into knowledge. Chenomx Inc. is a company that provides metabolomics research software and services. Its flagship software product Chenomx NMR Suite is an integrated set of tools for identifying and quantifying metabolites in Nuclear magnetic resonance (NMR) spectra.

Evaluation of adsorbents’ properties and optimization of adsorption based processes for gas separations

The objective of this project is, firstly, to evaluate the performance of various adsorbents using various techniques for gas separation and purification applications of commercial interest; and secondly, to optimize and modify the current PSA setup at Xebec Ads. Company. The proposed project will examine various adsorbents provided by Xebec Adsorption Inc. to determine their adsorption capacity, kinetics, selectivity, at different operating conditions.

Detection and characterization of biodegradable polymeric biomaterials

Biodegradable polymeric biomaterials have been used extensively for medical applications such as implants, drug/gene delivery, and scaffolds. To determine the end applications, the molecular characteristics of these polymeric biomaterials are important which must be characterized. The development of reliable and fast analytical tool to detect, separate and characterize polymeric biomaterials in medical devices and drug formulations is still challenging.

Scale Up of the Circulating Fluizied Bed Bioreactor for Municipal Wastewater Treatment

The project will focus on the development and installation of a modification to convert existing biological wastewater treatment systems (particularly, activated sludge and similar processes) to circulating fluidized bed bioreactors (CFBBR). The CFBBR has already been proven on the lab and pilot scale to have higher nutrient removal efficiencies and greater handling of high volumetric loadings. Following the installation, the enhanced removal efficiencies will be tested.

Evaluation and design of a novel CO2 methanation reactor integrated into a Biogas upgrading facility

Wind energy is the fastest growing source of electricity in Canada. However, its supply is not aligned with the energy demand, thus energy storage becomes important. The Power to Gas process (P2G) is a promising technology in which electrical energy is converted into chemical energy (methane). Methane can be stored in already existing natural gas distribution infrastructure. Within the P2G process, excess electricity is converted to hydrogen via water electrolysis and subsequently converted with CO2 (biogas upgrading) to methane.

Study on Coal and Coke Mineralogy and Development of a Model to Predict Reactivity from Mineralogy of Coking Coals

Properties of metallurgical coke are very important in production of iron using blast furnace. About 90% of the coking coals produced are used for this purpose. Coal rank was historically used to evaluate coal for production of metallurgical coke. Coke reactivity index (CRI) and coke strength after reaction (CSR) with carbon dioxide are now routinely used rank and value coking coals. The properties of the other components present in the ash may be the controlling parameters defining coke properties, which has not been studied well.

Development of Graphene Modified Cathode for Next Generation Aqueous Rechargeable Lithium Batteries

Aqueous rechargeable lithium battery has received great attention recently due to the less toxicity, lower cost and higher safety compared to the non-aqueous systems. When using the commercially available lithium manganese oxide as active materials, there are demands in suppressing manganese dissolution and graphite consumption in the cathode. As a potential solution to achieve these goals, in this proposal, two dimensional graphene materials are integrated on the surface of the cathode, forming a hybrid cathode aqueous battery.

Development of a renewable and small scaled heat and power generation system for remote location using woody biomass as fuel

The key objective of this research is to develop a unit for combined heat and power production using biomass feedstock that can be used in remote areas where no grid power is available. Canada as the second largest country in the world, has a great potential for such units. Aboriginal communities or remote work facilities are only two possible applications for this technology. The existing heat and power generation system mostly rely on diesel and natural gas.

Creating a Positive Safety Culture and Continuous Improvement in Alberta’s Construction Industry

To create the impetus for industry-level improvements in safety, the COAA has embarked on an initiative “Twice as Safe, Twice as Productive by 2020”. The purpose of this project is to support this initiative by understanding the safety cultures and the levels of maturity across the construction industry and motivating improvements in all Albertan construction companies. This will be accomplished by first surveying individuals working for owner companies, contractors, subcontractors and suppliers.
