Ce projet consiste à préparer et à caractériser des mélanges polymères capables à la fois d’un transport de charge ionique (polyélectrolyte) et d’un transport de charge électronique (polymère semi-conducteur). Ces mélanges, dont le système modèle sera à base de poly(oxyde d’éthylène) (PEO) et de polythiophène (P3HT), seront imprimés en 3D : l’hypothèse de travail est […]

La biomasse est considérée comme une source disponible et une alternative viable au pétrole. La lignine est actuellement une des formes de biomasse la plus ciblée car elle possède une structure polymérique unique contenant des unités aromatiques. Pour accéder aux motifs aromatiques a faible masse moléculaire, les chimistes ont ciblé la liaison ?-O-4 de la […]

Well-known Canadian montane national parks have undergone a length period of fire suppression activities, which started in the early 20th century. This has resulted in old growth forest stands that are relatively homogeneous in nature, often containing forests that have the same species, age, and structure. In recent years, mountain pine beetle outbreaks have occurred, […]

Le projet de doctorat consiste à faire l’essai d’un certain type de lentilles électroniques spécialisées, appelées lentilles à focalisation forte, que sont les lentilles quadripolaires électrostatiques. Ces lentilles sont généralement utilisées dans des appareils analytiques comme les microscopes électroniques et les spectromètres de masse, entre autres., qui opèrent tous à de très basses pressions. L’élément […]

Functional Electrical Stimulation (FES) is an effective technology for the therapy of patients who suffer from physical impairment. To increase the effectiveness of FES and reduce the cost of hospitalization, a new design is required for the remote and long-term application of FES so that the patients can easily undergo FES during their daily life […]

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. The 2017 national assessment by World Wildlife Fund-Canada found that 60 among […]

The reliance on raw materials from overseas to build lithium-ion batteries (LIBs) is a major concern for automotive companies building battery electric vehicles in North America. Canada’s rich Ni deposits is a potential solution to this problem. However, Canadian Ni ore are sulfides, so battery manufacturers are reluctance to use it due to possible trace […]

Laboratory pedagogy is considered absolutely critical for physics and engineering education ranging from high school to university. Among all universities worldwide, a well-known first-year physics experiment demonstration is a spring-coupled pendulums system. It demonstrates the coherent coupling; the underlying physics is reflected from classical mechanics to advanced quantum systems. It has excellent application from a […]

Light is a powerful sensing tool that humans are very familiar with. We are, however, only sensitive to a visible light. Much more can be learned from other types of light. Terahertz light is very low energy light that allows very sensitive non-invasive measurements to be made on many types of samples including biological and […]

A previous feasibility study performed at UBC on the Mount Polly samples showed that dense media separation gave copper recoveries of 95.8% at a specific gravity of 2.9. The purpose of this research project is to confirm the applicability of dense media separation for Mount Polley ore pre-concentration. A lab test will be performed as […]

There is a need for customers to use a simple test method to determine if the fuel blends they are using are of the proper composition for fuel efficiency, environment- friendliness and engine cylinder compatibility. But it is difficult to determine the composition of oil/fuel/ethanol mixtures without detailed and expensive chemical analysis. It is because […]

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 […]
