Comparing the Effect of 2nd Row Dopants on the Carbon Support to improve Pt Catalytic Activity and Durability

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

This work outlines improvements to the Pt catalyst durability and activity by modifying the carbon catalyst support for use in the proton exchange membrane fuel cell. Computational methods have shown that nitrogen and boron dopants [...]

Environmental Friendly Synthesis of Polypyrrole within polymeric Nanotemplates-mechanism of polypyrrole synthesis

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

This paper describes an innovative way to synthesize polypyrrole using self-assembly nano-templates poly (isobutylene-alt-maleic anhydride) (IMA) or poly (styrene-alt-maleic anhydride) (SMA). Understanding the details of the novel synthesis in great details would provide us profound [...]

Characterizing the Oxygen Reduction Reaction for the Proton Exchange Fuel Cell with with Novel Nanotechnology-based Catalyst Supports

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

The oxygen reduction reaction (ORR) on the cathode of the proton exchange membrane fuel cell is still inefficient. This work will focus on the activity of the catalyst when varying the catalyst support. In the [...]

Conformation of pH Responsive Alternating Copolymers and Self-Assembly in Nanoarchitectures

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

Our research focuses on the characterization of the association and the properties in aqueous solution of nanostructures composed of amphiphilic alternating copolymers. These copolymers are composed of a pH sensitive hydrophilic group, maleic anhydride alternating [...]

Predicting PEMFC Pt Catalyst Durability using DFT

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

DFT calculations using B3LYP/Lanl2DZ on nitrogen doped graphene and single walled carbon nanotube structures are evaluated using Gaussian03 to measure the binding energy between its surface and a Pt atom. This is to characterize the [...]

Conformational analysis of alternating copolymers and their association into nanoarchitectures

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

Our research focuses on the characterization of the association and the properties in aqueous solution of nano-structures, particularly on nanotubes composed of amphiphilic alternating copolymers. These copolymers constitute a pH sensitive hydrophilic group (maleic anhydride) [...]

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 [...]

Characterization of a Novel Self-Association of an Alternating Copolymer into Nanotubes in Solution

Malardier-Jugroot C., van de Ven T.G.M., Whitehead M.A., McGill University, CA

The characterisation of the association of an alternating copolymer was performed using theoretical methods (quantum mechanics and molecular mechanics) and experimental methods (cryo-Transmission Electron Microscopy, Neutron Reflectivity and Neutron Scattering). The most stable conformation obtained [...]
