Comprehensive Microscopy Analysis of Au/Ag Nanoclusters on Silica Nanospheres

Qian H., Shen W., Cui K., Cho J., Fenniri H., National Institute for Nanotechnology, CA

we report a comprehensive structural and morphological analysis of gold (Au) / silver (Ag) nanocluster (shell) on silica (SiO2) nanosphere (core) with transmission electron microscopy (TEM) based techniques, including scanning transmission electron microscopy (STEM) tomography, [...]

Raman Spectroscopy hyperspectral imager based on Bragg Tunable Filters

Marcet S., Verhaegen M., Blais-Ouellette S., Martel R., Photon etc., CA

A new type of Raman spectroscopy hyperspectral imager based on Bragg tunable filter has been developed by University of Montreal and Photon etc. The technology of Bragg tunable filter significantly reduces the acquisition time by [...]

Design and Application of Novel Nano Drilling Fluids to Mitigate Circulation Loss Problems during Oil Well Drilling Operations

Mostafavi V., Ferdous M.Z., Hareland G., Husein M., University of Calgary, CA

Nano-fluids have recently attracted attention in the petroleum industry as potential solutions to several shortcomings of conventional drilling fluids. Drilling fluid is in charge of numerous functions during the drilling operation including transport of cuttings [...]

Carbon-supported platinum and nickel nanoparticles for CO capture in hydrogen fuel cells

J. D. Durbin D., J. Fermin D., Plana D., J. D. Durbin D., J. Fermin D., Malardier-Jugroot C., Royal Military College of Canada, CA

Fuel cells are electrochemical cells that convert chemical energy into electrical energy with efficiencies up to 80%; they are a promising potential replacement for internal combustion engines in automobiles. However, carbon monoxide poisoning of the [...]

Optical absorption enhancement of thin-film amorphous silicon induced by femtosecond laser pulses for solar cell fabrication

Kiani A., Venkatakrishnan K., Tan B., Ryerson University, CA

In this paper, we present a new method for direct-write laser fabrication of thin-film amorphous silicon (a-Si) on crystalline silicon substrate induced by femtosecond laser irradiation. Using megahertz frequency femtosecond laser pulses makes it possible [...]

Celastrol-Based Nanomedicines as Modulators of Neuroinflammation

Boridy S., Hutter E., Soliman G., Maysinger D., McGill University, CA

Chronic inflammation plays a pivotal role in promoting disease pathology in the central nervous system (CNS). Microglial cells are the main innate immune effector cells in the CNS and orchestrate these neuroinflammatory reactions that ultimately [...]

Non-invasive Lesion Imaging and Delivery of Nano-Therapeutics to the Ischemic Brain

Choi A.O., Vaisheva F., Soliman G.M., Maysinger D., McGill University, CA

Silent brain infarcts are often asymptomatic, but these micro-lesions can cause considerable neurodegenerative damage if they remain undetected and untreated. Cells undergo rapid irreversible necrosis at the ischemic core; however, viable cells in the penumbra [...]

PEG Incorporated Polymeric Microcapsules for Intramyocardial Delivery of Stem Cells Genetically Modified by Baculovirus

Paul A., Khan A.A., Abbasi S., Shum-Tim D., Prakash S., McGill University, CA

The ability of mesenchymal stem cells to self-renew and differentiate into specialized cell lineages makes them promising tools for regenerative medicine. Local injection and use of scaffolds had been employed earlier to deliver these cells; [...]
