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 [...]

Amplified On-Chip Fluorescent and Colorimetric Detection of DNA and RNA Hybridization by Surface-Initiated Enzymatic Polymerization

Tjong V., Yu H., Hucknall A., Chilkoti A., Duke University, US

We present a new on-chip, isothermal signal amplification technique for direct detection of unmodified DNA and RNA on microarrays using terminal deoxynucleotidyl transferase (TdT), a template-independent DNA polymerase that catalyzes the sequential addition of deoxynucleotides [...]

Polymerization Passivation Strategies for the Stabilization of Energetic Aluminum Nanomaterials

Jelliss P.A., Thomas B.J., Patel A., Lloyd E., Guliants E.A., Bunker C.E., Buckner S.W., Saint Louis University, US

We are developing aluminum nanoparticle (Al NP) passivation strategies based on our established protocols for polymerization of epoxide molecules with a view to fabricating air-stable Al NPs with long shelf-lives. Additionally we have discovered that [...]

Synthesis and characterization of polypyrrole nanowires using alternating amphiphilic copolymer nanotubes as templates

Chan A.S.W., Groves M., Malardier-Jugroot C., Royal Military College of Canada, CA

It has been reported that poly(styrene-alt-maleic anhydride) (SMA) chains would self-assembled into a nanotube in aqueous solution at pH7 by associating through a linear conformation which favours the association of the chains by decreasing the [...]

New route to manufacture high performance carbon nanotubes nanocomposites based on pre-dispersed concentrates generated by in-situ polymerization

Claes M., Bonduel D., Pegel S., Alexandre M., Poetschke P., Dubois P., Luizi F., Nanocyl SA, BE

We describe here an original method which relies upon the in situ polymerization of olefin catalyzed by a highly active metallocene complex physicochemically anchored onto the carbon nanotube surface. As a result, carbon nanotubes are [...]
