Since its inception at the inaugural APICS meeting in 1962, the Chemistry Committee has been active in organizing its Tour Speaker Program, bringing accomplished scientists in the field right to the classroom of Atlantic Canadian students.
2010-11 tour speakers:
Christa Brosseau
Assistant Professor
Department of Chemistry
Saint Mary's University
September 24 — Memorial University
October 29 — Cape Breton University
TBA — Mount Saint Vincent University
Title: New Frontiers in Surface-Enhanced Raman Spectroscopy
Abstract: SERS, or surface-enhanced Raman spectroscopy, has experienced a resurgence in recent years, owing to the development of stable high-powered lasers, ultrasensitive detectors and well characterized nanomaterials. This resurgence has resulted in the implementation of SERS as an analytical tool in such varied areas as art conservation, biomedical engineering and fuel cell technology.
In this seminar, I will first discuss work which was completed at Northwestern University and the Art Institute of Chicago which used SERS to analyze items of cultural heritage, including paintings and textiles. In addition, I will highlight new research coming out of our research group at Saint Mary's University which uses SERS to analyze and characterize such varied systems as cultural heritage properties, hip implant materials and novel biodegradable ionic liquids.
Vicki Meli
Assistant Professor
Department of Chemistry
Mt. Allison University
September 29 — UNB Fredericton
November 5 — Dalhousie University
January 5 — University of Prince Edward Island
Title: Insights into the Formation of Nanoparticle Monolayers at Fluid Interfaces
Abstract: Nanoparticles have several properties of technological importance, most of which are strongly influenced by the nanoparticle shape, size, and chemical environment. Using the air-water interface to drive the formation of thiol-capped gold nanoparticle monolayers, we have explored the effects of interfacial tension via solvent, thiol chain length, and core size on monolayer formation. Several different film morphologies, and consequently physical properties, have now been observed and will be presented. The application of these films toward understanding nanoparticle-liquid crystal interactions and their effect on liquid crystal self-assembly will also be described.
