1. Farewell Board Members

After serving as Chair of the Board of Directors for the past four years, Dr. Walter Davidson chaired his last meeting on June 19. A celebratory dinner to pay tribute to his contributions took place on June 18. Dr. Davidson will remain a Board member until December.

In addition, the Board said farewell to two of its longest serving members, Don Brooks, University of British Columbia, member since 2006 and Emil Pai, Ontario Cancer Institute, member since 2001.

We are most grateful for these dedicated Board members’ vision, commitment, and leadership. On behalf of the entire CLS community, thank you.



2. Voting for Users' Advisory Committee members: July 7 - July 25

A request for you to participate in the online election will be distributed on Monday, July 7. If you do not receive a request to vote by email, please contact David Hawthorn or the CLS Users' Office.

The new Chair and Vice Chair of the UAC for 2014-15 are, respectively, Andrew Grosvenor, University of Saskatchewan and Jeff Warner, Cameco Corporation. Their terms begin in September.

Four members have succesfully completed their terms of the UAC. The CLS would like to thankKen Burch, Boston College, Jennifer van Winjgaarden, University of Manitoba, Kirk Michaeilian, Natural Resources Canada, and Adrian Hunt, University of Saskatchewan, for their service to the user community and their work on behalf of the facility.


3. Call for interest in artist - scientist collaboration

Local artist JS Gauthier is looking for a researcher interested in collaborating on a pilot project from the Canada Council for the Arts with up to $60,000 each for the artist and the researcher available. An artist and a scientist would be co-applicants and propose a single project that has both an artistic and scientific elements. The project will use media arts as a means of artistic expression, combined with peer-reviewed research. Grants cover the direct costs of research, creative development, production and presentation of artworks created through media arts practices.

Gauthier's art involves experimental creation time-based art. His principle tools include a mix of contemporary sculpture, video and performance art practices. His work often involves humour and raw aesthetics imbued with childlike playfulness. He is ever enthusiastic to engage in creative collaboration.

4. Large-Area, Freestanding, Single-Layer Graphene–Gold: A Hybrid Plasmonic Nanostructure

Graphene-based plasmonic devices have recently drawn great attention. However, practical limitations in fabrication and device architectures prevent studies from being carried out on the intrinsic properties of graphene and their change by plasmonic structures. The influence of a quasi-infinite object (i.e., the substrate) on graphene, being a single sheet of carbon atoms, and the plasmonic device is overwhelming. To address this and put the intrinsic properties of the graphene–plasmonic nanostructures in focus, we fabricate large-area, freestanding, single-layer graphene–gold (LFG-Au) sandwich structures and Au nanoparticle decorated graphene (formed via thermal treatment) hybrid plasmonic nanostructures.

The authors observed two distinct plasmonic enhancement routes of graphene unique to each structure via surface-enhanced Raman spectroscopy. The localized electronic structure variation in the LFG due to graphene–Au interaction at the nanoscale is mapped using scanning transmission X-ray microscopy. The measurements show an optical density of 0.007, which is the smallest experimentally determined for single-layer graphene thus far. Our results on freestanding graphene–Au plasmonic structures provide great insight for the rational design and future fabrication of graphene plasmonic hybrid nanostructures.

5. Bronze Age skull shot with an arrow reveals secrets of ancient society

Unlike most hunter-gatherer societies of the Bronze Age, the people of the Baikal region of modern Siberia (Russia) respected their dead with formal graves. These burial sites are a treasure trove for archeologists and one particular specimen was so unique that bioarchaeologist Angela Lieverse traveled across the world just to bring it back to the CLS for examination.

6. CLS Partners with Mitacs

The CLS has signed a memorandum of understanding with Mitacs, a national, not-for-profit organization that brings together academia, industry and the public sector, to develop cutting edge tools and technologies vital to Canada’s knowledge-based economy.

7. New staff and now hiring

The CLS is pleased to welcome Peter Blanchard, Industrial Science Research Associate. Peter joined the CLS after returning to Canada from Australia where he held a postdoctoral research associate position at the University of Sydney. Prior to living in Australia, Peter obtained his PhD in Chemistry from the University of Alberta and did his undergraduate studies at Memorial University in Newfoundland. In addition to supporting industrial research clients, Peter will be working on a collaborative project with Andrew Grosvenor from the University of Saskatchewan and AREVA Resources Canada Inc. to improve understanding of the long term disposal of mill tailings, important in future mine site reclamation.

The following job postings are currently available at CLS:
