Surface Modification of Single-Wall Carbon Nanotubes by Photo-Initiated Chemical Vapor Deposition Utilizing Syngas

Hosseininasab S., Faucheux N., Soucy G., Tavares J.R., polytechnique montreal, CA

single wall Carbon nanotubes (SWCNTs) have various individual properties. These individual properties make them promising candidates for a wide range of applications, but their inherent hydrophobicity are the most challenging features for them. we propose [...]

Polymer Nanocomposites Incorporating Boron Nitride Nanotubes

Jakubinek M.B., Martinez-Rubi Y., Ashrafi B., Guan J., Kim K.S., O’Neill K., Kingston C.T., Simard B., National Research Council Canada, CA

Boron nitride nanotubes (BNNTs) are structurally analogous to carbon nanotubes (CNTs) and possess equally impressive mechanical properties along with a different set of multifunctional properties including higher thermal stability than CNTs, wide band gap, electrical [...]

Tracking Nanoparticles in Biological Fluids using Single Particle ICP-MS

Stephan C., Cirtiu C.M., PerkinElmer, CA

Single Particle-ICP-MS is a new operating mode in ICP-MS that is dedicated to the analysis of engineered nanoparticles (ENPs) commonly used in Nanomedicine and drug delivery systems. Single Particle (SP-ICP-MS) allows the differentiation between ionic [...]

Characterization of Metal-Based Nanoparticles by Single Particle-ICP-MS in Various Matrices

Stephan C., Hinemaan A., PerkinElmer, CA

The use of nanoparticles in consumer products is showing a tremendous increase over time. The National Institute of Standards and Technologies reported that nanotechnology-based consumer products are currently entering the market at a rate of [...]

Cross-Linked Single-Walled Carbon Nanotube Buckypapers and their Composites

Guan J., Jakubinek M.B., Ashrafi B., Johnson M., White M.A., Simard B., National Research Council Canada, CA

Single-walled carbon nanotubes (SWCNT) covalently modified with OH functional groups were assembled into buckypapers through solvent dispersion and vacuum filtration. These SWCNT-OH buckypapers were subsequently crosslinked by wetting with bifunctional linkers followed by hot compression, [...]

Photothermal Structural and Optical Changes In GaAs Nanowires

Walia J., Dhindsa N., Flannery J., LaPierre R., Forrest J., Saini S.S., University of Waterloo, CA

The structural and optical changes in vertically etched GaAs nanowires are examined. The nanowires were annealed via photo-thermal conversion, using 100 mW of incident laser power, to induce the onset of arsenic formation. Four nanowire [...]

Synthesis and characterization of nanoreactors within polymeric nanotemplates

McTaggart M., Groves M., Malardier-Jugroot C., Jugroot M., Malardier-Jugroot C., Royal Military College of Canada, CA

The paper will present a novel method for the synthesis of metal nanoclusters with diameters < 3nm within an amphiphilic nanotube template without the use of a reducing agent. This environmentally friendly synthesis occurs at [...]
