1. New CLS Executive Director Announced 

Following an extensive international search, Australian scientist Robert Lamb has been selected to lead the CLS effective August 1, 2014.

The appointment was jointly announced this week by the Chair of the CLS Board of Directors, Walter Davidson, and University of Saskatchewan President, Ilene Busch-Vishniac.

2. Call for Proposals opens Wednesday, January 29, 2014 for cycle 20 (July - December, 2014)

Deadline: February 26, 2014 - noon CST 
Schedule: www.lightsource.ca/operations/schedule.php
Contact: clsuo@lightsource.ca

General user proposals received for operational beamlines are reviewed for safety and technical feasibility, and then scored for scientific merit by an external review committee. Research time obtained through this competitive peer review process takes place twice per year. General user research should result in the publication of scientific results.

You have the option of submitting a new proposal or submitting a beam time request against an active proposal. Allocation of shifts for July - December, 2014 will be based on the highest ranked proposals (both new and active). To view evaluation criteria used in reviewing and rating proposals see www.lightsource.ca/uso/proposal_writing_tips.php or to compare your score to others on the same beamline, please visitwww.lightsource.ca/uso/results_of_call.php.

In addition to normal mode operations at 250 mA, six shifts will be available for coherent synchrotron radiation studies. These shifts must be applied for through the general user program.

To find out which beamlines are available for cycle 20 and for Canadian access to beam time at the APS, contact clsuo@lightsource.ca or visitwww.lightsource.ca/uso/call_proposals.php

3. Science Highlight: Superconductor discovery an advancement for technology

Using the CLS, scientists have discovered a universal behavior in copper-based (cuprate) superconductors, paving the way for a crucial advancement in understanding and development of these fascinating materials that will have implications on everything from producing smaller, more efficient MRI machines to making better power lines.

The international team, led by University of British Columbia researchers, in collaboration with scientists from the CLS, and other groups from Germany, Japan and United States, found that the so-called charge-density-waves – spatial modulations of the electronic density in a crystal – are the same in all cuprate compounds.

4. Science Highlight: Revealing the Role of Catalysts in Carbon nanotubes and nanofibers by Scanning Transmission X-ray Microscopy

The identification of effective components on the atomic scale in carbon nanomaterials which improve the performance in various applications remains outstanding challenges. Here the catalyst residues in individual carbon nanotube (CNT) and carbon nanofiber (CNF) were clearly imaged with a concurrent characterization of their electronic structure by nanoscale scanning transmission X-ray microscopy. Except for prominent catalyst nanoparticle at the tip, tiny catalyst clusters along the tube (fiber) were detected, indicating a migration of the catalysts with the growth of CNTs (CNFs). The observation provides the direct evidence on the atomic metal in CNT for oxygen reduction reported in the literature. Interaction between catalysts (Fe, Ni) and CNTs (CNFs) at the tip was also identified by comparing the X-ray absorption spectra. A deep understanding of catalyst residues such as Fe or Ni in carbon nanomaterials is very vital to growth mechanism development and practical applications.

8. Applications of Synchrotron Imaging for Crop Improvement

The Application of Synchrotron Imaging for Crop Improvement Workshop will explore the application of synchrotron light to imaging plants to support the selection and development of superior crop lines. The workshop will look at ways plants can be structurally and functionally imaged, in-vivo to in-situ, and applying this information to aid in the development and selection of higher yielding crop varieties. It will also focus on imaging all components of the plant, from root to stem. It is believed that imaging will be a key tool in achieving the substantial increases in crop productivity to feed the world’s growing population.

Join researchers and industry partners for presentations, exhibitor booths, a poster session, networking events and a tour of the CLS. You will have opportunities to meet some of the world’s leading innovators in this industry, in both research and commercialization.
