This project aims to develop sprayable coatings to prevent the prevent the attachment of bacteria on tables, door handles and other countertops. This will be obtained by modifying the surface with natural materials (such as vitamin B5 mimicking polymers and cellulose nanocarriers) that can deter bacterial attachment upon contact. The spray coated surfaces will sense the bacterial adhesion on the surface and will undergo color change, indicating the surface fouling and need to reapply the coating on the surface as needed.
Healthy freshwater ecosystem plays a vital role in every Canadian’s daily life as primary drinking water source and sustains the social and economic status of Canada. However, Canada’s freshwater ecosystem has been negatively impacted by population growth, urbanization, industrialization, agriculture, and climate changes.
Cellular agriculture aims to generate more sustainable approaches to the production of agricultural products, and this nascent field requires the development of new tools to enhance controlled cell growth. In this project, we will investigate the use of insect cell biomass to produce specific phospholipids that can be used to enhance cellular growth. We will examine known pathways that are activated by exogenous phospholipids in mammalian cells. We will determine optimal compositions and formulation of the lipids for stimulating cell growth in multiple cell lines.
Despite the promise of cannabis containing goods as medicines and consumer products, the lab-intensive and time-consuming extraction process impedes applications of these compounds. Consequently, there is an urgent need to develop more effective extraction methods to access these high-value materials. Carbon dioxide supercritical fluid extraction is the typical technique to recover cannabinoids from cannabis plants with high levels of enrichment.
The multi-elemental analysis of solids typically requires their dissolution, which is time-consuming and very difficult, and sometime virtually impossible. During this project, a new method will be developed for the direct analysis of solids that are notoriously difficult to dissolve. The sample will be inserted into a small furnace whose temperature will be changed in steps in order to selectively vaporize the elements of interest into the detection system. To facilitate the process, gases that can react with the solid in the furnace will be introduced into the furnace.
Antimicrobial resistance (AMR) occurs when antibiotic drugs and products stops working, making it difficult to treat infections and diseases which could lead to further health complications and death. Therefore, development of antibiotic products is needed to control the increasing cases of AMR. Medicinal plants are a great source of natural antibiotic compounds to make antibiotic drugs and products.
This project aims to develop a new polyrotaxane-based additive compatible with a poly(methyl methacrylate) matrix using called controlled radical polymerization technique, which is much tolerant to impurities, and thus can be carried out at a much lower cost than anionic polymerization. The new additive will provide great impact resistance to rigid poly(methyl methacrylate) at low concentrations (ideally, 1-2% by weight).
Polydicyclopentadiene (PDCPD) is a tough, heavily crosslinked thermoset polymer. An extensive network of crosslinks gives PDCPD a very high impact resistance, good resistance to chemical corrosion, and a high heat deflection temperature. University of Victoria (UVic) recently achieved the creation of the first functionalized polydicyclopentadiene (f-PDCPD) that does not give up the robust thermal stability that makes PDCPD so useful. Poly V Technology has been launched to translate this novel functionalized polymer to a commercial setting.
The project will entail the production and characterization of hydrogen silsesquioxane (HSQ), a useful material for both lithography and production of silicon nanomaterials. This material is the workhorse for Applied Quantum Materials Inc. (AQM), as it is one of their central products that they supply to the e-beam lithography industry as well as the precursor for their silicon nanomaterials.
The methods for screening complex biological samples found wide application in pharmaceutics, forensic science and medical science. The majority of these methods involve several analytical techniques coupled together in order to maximize the efficiency of the analysis. For example, the combination of Capillary Electrophoresis (CE) with Mass Spectrometry (MS) creates a new analytical platform (CE-MS) that utilizes the separation power of CE and superior detection abilities of MS.
