1. NEW DIRECTOR OF TECHNICAL SUPPORT
Contact: josef.hormes@lightsource.ca

After an extensive international search, I am pleased to announce the appointment of Mike McKibben as the CLS’ new Director of Technical Support. Mike has been with the CLS for the last 8 years as a controls engineer and supervisor. I am confident that Mike’s extensive experience and familiarity with the unique requirements of our facility make him very well-suited to guiding the efforts of our technical staff as the CLS continues to grow into an excellent user facility.

I would also like to thank Mark Silzer for his continued service as Assistant Director of Technical Support and congratulate him on his new appointment as our Phase III Project Leader.

Josef Hormes,
CLS Executive Director

2. 2009 CLS ACTIVITY REPORT NOW AVAILABLE
Contact: matthew.dalzell@lightsource.ca

The 2009 CLS Activity Report was officially launched at the Annual Users’ Meeting. Copies of the report can now be requested through cls@lightsource.ca

The report will be available online shortly, to be downloaded in its entirety or as individual articles. Copies will also be mailed to users this summer.

Thanks to all the contributors, as well as the many volunteer editors and reviewers, for making this year's report a success.

4. RESEARCH HIGHLIGHT: Site-Specific and Size-Dependent Bonding of Compositionally Precise Gold-Thiolate Nanoparticles from X-ray Spectroscopy
Contact: peng.zhang@dal.ca

Understanding the site-specific and size-dependent structure and bonding properties of gold-thiolate nanoparticles is one of the most fundamental questions in nanoscience. The recent synthesis of compositionally precise Aum(SR)n nanoparticles offers a promising opportunity to explicitly elucidate the structure-property correlation of nanomaterials from site-specific and size-dependent perspectives. Herein, we report an X-ray absorption (gold L3-, sulfur K-, and L3,2-edge) and photoemission (gold 4f, sulfur 2p, and valence band) study of compositionally precise Aum(SR)n nanoparticles. An X-ray spectroscopy approach to deduce the atomic structure of Au144(SR)60 is first demonstrated. In conjunction with ab initio calculations, a high-precision, atomic-site-specific illustration of the bonding in Au144(SR)60 is achieved. By comparing size-varied samples [Au144(SR)60, Au38(SR)24, and Au25(SR)18], the size-dependent nature of bonding in gold-thiolate nanoparticles is revealed from both the sulfur and gold perspective.

This research was performed by a collaboration from Dalhousie University (MacDonald and Zhang) and Carnegie Mellon University (Qian and Jin) using the SXRMB, PGM, SGM and HXMA beamlines at the CLS.

5. CLS GRADUATE STUDENT TRAVEL SUPPORT PROGRAM
Contact: tom.ellis@lightsource.ca

The CLS places a high value on student training. The facility offers an ideal environment for graduate students to have access to world-class facilities, and to interact with scientific colleagues from around the globe. The Graduate Student Travel Support Program was developed to enhance access to the CLS by graduate students from Canadian colleges and universities.

This program will be available starting with Cycle 12 (July - December 2010). Each grant has a maximum value of $1500. The application process is now open and will be filled on a first come, first served basis.

For more information regarding the application process and eligibility criteria, please visit: http://www.lightsource.ca/uso/travel_support.php

6. NEW SCIENCE WITH RESONANT ELASTIC AND INELASTIC X-RAY SCATTERING, SASKATOON, JULY 8-9
Contact: alex.moewes@usask.ca

On July 8 - 9, 2010, an international conference on "new science with resonant elastic and inelastic scattering" will be held on the campus of the University of Saskatchewan. For the program, registration and conference details please check out the conference website: http://www.vuvx2010.ca/showcontent.aspx?MenuID=673

The focus of this meeting will be on discussing the forefront of science with synchrotron-based soft X-ray scattering and its future directions. CLS is home of the REIXS beamline that is currently being commissioned and will use elastic and inelastic resonant scattering. World-experts will present the science questions that will be addressed with X-ray scattering techniques. An exciting group of speakers will present on relevant topics such as Inelastic and Elastic X-ray Scattering, Applications, Theory, and New Instruments.

The conference is a satellite meeting to the VUVX conference in Vancouver on July 11-16. For further information, please contact the conference chair Alex Moewes (alex.moewes@usask.ca).

7. SURVEY: PLANNING FOR 2010 ACTIVITY REPORT
Contact: matthew.dalzell@lightsource.ca

Planning will soon start for the 2010 Activity Report, including exploring possibilities for changing the report's format, scope and exploring alternative means of delivery. Your input into this process is encouraged, either by email to the above or by completing a short (8 question) survey at http://www.surveymonkey.com/s/VJZT29R by August 31, 2010.

8. CONGRATULATIONS TO AWARD-WINNING CLS USER

Congratulations to University of Saskatchewan graduate student and Mid-IR user Ricky Lam, one of the first recipients of the Governor General’s Award in Celebration of the Nation’s Table. He was recognized in the award’s Youth category for his research into the food applications of edible oils and fats using the CLS under the supervision of Dr. Michael Rogers.

The Governor General’s Award in Celebration of the Nation’s Table recognizes and celebrates outstanding efforts in improving the quality, variety and sustainability of all elements and ingredients of our nation’s table.

Read the news release from Rideau Hall: http://www.gg.ca/document.aspx?id=13710. Some of Mr. Lam’s research was recently published in the journal Soft Matter, co-authored by CLS staff Luca Quaroni and Tor Pedersen (Lam et al. 2010, DOI: 10.1039/b919477k).
