Polymers for Nanoscience and Nanotechnology, at the 90th Canadian Society for Chemistry Conference, May 2007, Winnipeg, Manitoba
The symposium, co-organized by Yue Zhao (University of Sherbrooke, Canada) and Wai Kin Chan (University of Hong Kong), was successful. It was a joint symposium featured by the Macromolecular Science and Engineering Division (MSED) and the Materials Chemistry Division of the Canadian Society for Chemistry (CSC). All three sessions were well attended by graduate students and faculty with maximum numbers varying between 24 and 40, despite the many parallel symposia. The support from the PRF funds allowed the organizers to invite eight outstanding international (4), US (2) and Canadian (2) speakers whose fundamental research covered a variety of current topics in the important area of nanoscience and nanotechnology involving or enabled by polymers. In addition to the eight exciting invited lectures, the symposium's program was completed with eleven much-appreciated contributed presentations, about half of which were given by graduate students, and several posters.
Among the highlights, the synthesis and characterization of nanoscale polymers of particular architectures were discussed byProf. Daniel Guillon (Institute of Materials Physics and Chemistry of Strasbourg, France), whose lecture was entitled ‘Nanostructured Functional Materials Based on Organic and Hybrid Dendritic Architectures”, and by Prof. Scott Garyson (University of Tulane) who spoke on “Cyclic and Toroidal Polymers Prepared Using "Click" Chemistry”. Researches on block copolymers, which can self-organize into a variety of nanostructures both in solid state and in solution, have been increasingly active. Prof. Guojun Liu (Queen's University, Canada) gave his MSED award lecture on “Nanoworld of Block Copolymers - Block Copolymer Assembly, Chemical Processing and Nanomaterial Application”, while Prof. Sebastien Lecommandoux (University of Bordeaux, France) presented his work on “Hierarchical and Functional Nanostructures from Rod-Coil Block Copolymers”. The use of molecular self-assembly to make new nanostructured objects was featured in the lecture of Prof. Yves Dory (University of Sherbrooke, Canada), being entitled “Rational Design of Crystals and Supramolecules Constituted of Parallel Stacks of Cyclic Peptides”. On the other hand, Prof. Rigoberto Advincula (University of Houston) discussed “Nanopatterning and Electrochemical Nanolithography of Precursor Conjugated Polymer Ultrathin Films”; Prof. Takashi Kato (Tokyo University, Japan) presented exciting new results on “Biomineralization-Inspired Inorganic/Organic Materials”; while Prof. Soo-Young Park (Seoul National University, South Korea) gave a lecture on “Enhanced Fluorescence Emission and its Photochromic Switching in Polymer Films: Realization of High Performance Optical Memory”.
The contributed presentations also covered various topics including functionalized carbon nanotubes, polymer nanoparticles for controlled drug delivery, nanostructured functional materials based on layer-by-layer assembly and polymer-dispersed nanoparticles for inkjet-printed electronics. The whole of presentations was of high quality and sparked off much interest among the audience.
The generous support from the ACS Petroleum Research Fund for this symposium was acknowledged in the official web site of the CSC meeting and during the symposium.
