Nowadays the spread of different kinds of pathogens such as bacteria and viruses like COVID-19, dyes, heavy metals, etc. into the environment cause a threat for all human beings, living microorganisms, and nature.
Lithium-ion batteries have revolutionized electronics over the past two decades, however, they do not have sufficient energy density to meet the long-term needs of society, such as the development of electric vehicles. This formidable challenge has driven research into many new battery technologies with different chemistries and configurations, but it remains unclear which technology is best-suited to surpass Li-ion batteries.
Rechargeable aqueous zinc ion batteries (RAZBs) have been used extensively because of their safety and low-cost. As an available cathode material for ZIBs, layered vanadium oxide (V2O5) has been considered due to its high specific discharge capacity. Because V2O5 is slightly soluble in water, it is suitable for doping V2O5 with metal ions to stabilize its layered structure and decrease the solubility of V2O5 in aqueous electrolyte systems. Hydrothermal method will be used to insert metal ions into V2O5 interlayer and shape the commercial V2O5 into nanobelts.
Cystic fibrosis (CF) is the most common fatal genetic disease affecting Canadian children and young adults, without a cure. Nanoparticles (NPs) have emerged as a promising strategy for delivering genetic treatments for various diseases. However, the development of NPs to treat CF has encountered many obstacles. This is mostly because the human airways, which constantly secrete mucous, pose a challenging environment for the efficient NP-mediated delivery of gene therapy. Several strategies have been proposed and tested; however, rational design criteria for these NPs are still missing.
Blood tests are highly sought after to enable earlier cancer detection. We previously developed a blood test for breast cancer that is in prospective clinical study in Alberta, Manchester (UK), Oklahoma (USA) and South Korea. The proposed project will investigate some clinical samples collected through this work to support the primarily focus of identifying biomarkers for a new cancer, multiple myeloma (MM). MM has a need for new monitoring approaches as it accounts for 10% of hematologic malignancies and is hard to cure, with a low five-year survival rate.
COVID-19 first emerged in China in December 2019, resulting in one of the worst pandemics of the modern history. To this date (June 2020), about 6 million people have been diagnosed with COVID-19 and more than 360,000 people have lost their lives to this novel disease. The cleaning and disinfecting protocols developed by the World Health Organization (WHO) have proven to be highly efficient in breaking the chain of transmission of viral pandemic diseases.
This project proposes the use of carboxylated cellulose nanocrystals (CNC) - developed and manufactured by Anomera Inc. from Canadian forest - as a nanosized ingredient to tailor a set of properties in composites made from water-based latexes used for coating applications such as sealants and paints. Incorporation of the CNCs will enhance the performance of the coating and prolong its lifetime. Due to its unique properties, CNC can significantly enhance the durability of coatings, making them more resistant to abrasion, scratches and impact, thereby extending their useful lifetime.
The risk of airborne disease transmission is high for essential workers even while wearing PPE. Since SARS-CoV-2 can remain airborne after a sneeze or cough for several hours, ideally, there would be effective methods to remove these infectious particles directly from the air. In this work, we develop a membrane-based technology capable of serving the two-in-one function of dehumidification and decontamination of the indoor air, which can be coupled to room A/C systems.
Herbal oils and oleoresins are components extracted from flowers, bark, leaves, roots, or fruits. These extracts are used as fragrances, flavoring agents, antimicrobials, and therapeutic agents with a market value of more than USD 8.5 billion and 7% annual growth. Steam and solvents are used to extract oils and oleoresins (respectively), but they have limited extraction efficiency, are energy-intensive, and emit greenhouse gases (GHG). Solvent extraction can also emit volatile organic components (VOCs) and produce flammable environments.
The oil and gas industry often contain a certain amount of CO2, H2S and chlorine compounds. H2S can cause sour corrosion and sulfide stress cracking (SSC) of stainless steels. Failures due to H2S are usually sudden with no warning. SSC is the worst type of corrosion in the presence of H2S. Many methods have been suggested to mitigate SSC and other corrosion issues in wet and sour service. Considering the design and the operation environments, the most practical solution is to change the materials of construction and select alternative material and/ coating to suit the specific need.
