PbS CQDs solar cells have limitations of improving the efficiency due to low open-circuit voltage (Voc) and low absorbance between 600 nm and 900 nm. To solve these problems, PbS CQDs-polymer hybrid tandem solar cell was developed by introducing a low band-gap polymeric photo-active layer, exhibiting high absorbance in the region of 600 nm to […]

Recently, speleothems from various Korean limestone caves have received special attention as an invaluable paleoclimatic archive for both regional and global aspects. Although recent investigations show distinctive relationships between their stable isotope compositions and surface environmental conditions, the quantitative understanding on the relationship is needed for more accurate and precise reconstructions of past climatic factors […]

Metal-organic polyhedra (MOPs) are discrete molecular capsules formed by coordination of metal ion and organic linkers. They possess a nanoscale cavity which can have potential applications in gas storage, separations, drug delivery or sensing. To enhance their usage for practical purposes, these materials need to be translated into membranes. MOP-polymer composites where MOPs are blended […]

Global Positioning System (GPS) multipath reflectometry (GPS-R) has recently emerged as coastal sea level altimetry technique. GPS-MR is based on the simultaneous reception of direct and reflecting satellite signals, exploiting the signal-to-noise ratio measurements. Atmosphere affects the GPS signals proportionally to the height of the antenna and results to underestimation of the tidal amplitudes. Over […]

The wild blueberry is an important crop in the Canadian Atlantic provinces with 140 million kg of fruit being produced in 2016 with a farm gate value of $155 million. However, gray mold disease caused by Botrytis cinerea can cause substantial damage with 20% crop losses being reported. This study seeks to the genes and […]

Ibuprofen is at the top of the World Health Organizations listing of essential medicines. As such, Ibuprofen is commonly consumed in nearly all countries. Considering Ibuprofen is poorly degraded by the human metabolism, wastewater tends to be a significant source of Ibuprofen in the environment. Concern has arisen over the past decade due to Ibuprofens […]

This project will assess the value in measuring sustainability outcomes according to place-specific baselines rather than universal thresholds set by rating systems and frameworks. It seeks a stronger foundation for sustainable design that can acknowledge place-specific factors. Ultimately, this work will lead to the establishment of a decision-making protocol about sustainable design options and outcomes […]

SemiosBIO is developing biopesticide technologies for the pest control industry. The products are intended for several markets, including agriculture, home and gardens, professional pest control operators (eg for hotels and commercial spaces) and forestry. semiosBIO has intellectual property that is being developed and tested in collaboration with 7 different organizations across Canada. The role of […]

Electric power is almost entirely transmitted through polymer insulated cables or wires in every home, factory, plant or apparatus. If the temperature of a cable increases, it would be an indication that some accidents or malfunctions such as inflow of excess electric current occur in the cable. The generated heat, indeed, degrades the polymer insulations […]

This project will combine filtration characterization and advanced 3D imaging and modelling of material structures to find ways to improve the recovery of process water from difficult-to-treat tailings that are the by-product of mining and mineral processing. This process is called solid-liquid separation and it is a critical area for the reduction of oil sands […]

Afin de gérer les réservoirs hydroélectriques, des modèles hydrologiques sont utilisés pour estimer les divers apports et sorties d’eau. Ces modèles comprennent typiquement une estimation empirique de l’évapotranspiration qui est la même pour l’ensemble du territoire. Or, les conditions régissant l’évaporation au-dessus d’un plan d’eau diffèrent de celles en milieu terrestre. De plus, les modèles […]

This project aims to develop a numerical tool for predicting accurately resonance frequencies of high-heads hydraulic turbines. Both the presence of water and the rotation of the disk-like structure induce shifts in these frequencies compared to a standing disk in air, respectively added mass and mode split. The project is articulated around the following steps: […]
