DXC 2011 Summary

The 60th Annual Denver X-ray Conference (DXC) was held in Colorado Springs, Colorado, home of the Garden of the Gods, Cave of the Winds, and the Royal Gorge Bridge. The event was hosted at the Crowne Plaza Colorado Springs hotel from 1-5 August 2011. The meeting attracted nearly 330 attendees and 130 exhibit staff.

Conference week began with 16 half-day tutorial workshops for DXC, held on Monday and Tuesday. Topics for the DXC workshops included:

In addition to the traditional XRD & XRF topics, a specialized session on Core Shell Spectroscopy was also featured at the conference, with 2 invited talks and 5 contributed talks.

The Plenary Session, Foods & Drugs, took place on Wednesday morning and was organized by Timothy Fawcett, International Centre for Diffraction Data and Mary Ann Zaitz, IBM. Four invited talks were given during the plenary session:

Edible Nanostructures – The Pleasures of Chocolate
Alejandro G. Marangoni, University of Guelph, Guelph, ON, Canada

From the Field to the Lab – FDA Use of XRF to Monitor Foods, Drugs and Other Consumer Products
Peter T. Palmer, San Francisco State University, San Francisco, CA
R. Jacobs, S. Yee, C. Qiu, M. Nausin, C. Castro, M. Muckenfuss, FDA, Alameda, CA

What Else Are You Drinking When You Drink Whiskey or Wine?

At the Plenary Session, the 2011 Barrett Award was presented to Dr. Juan Rodriguez-Carvajal, Institute Laue-Langevin, Grenoble, France to honor his exceptional contributions to the field of X-ray diffraction, in particular for his work on characterization of the structural and magnetic properties of strongly correlated oxides using diffraction techniques and for writing and freely disseminating FULLPROF, the most widely used Rietveld refinement program for analysis of crystallographic and magnetic structures. Dr. Rodriques-Carvajal was unable to travel to the meeting, so the award was accepted on his behalf by Anne Bonnin, ESRF, Grenoble, France.

The 2011 Jenkins Award was also presented at this year’s conference.  Dr. Paul K. Predecki received the honor for his contributions to the development of X-ray methods for a wide variety of materials, and his generosity in teaching and inspiring others in X-ray materials analysis both at the University of Denver and through organization and management of the Denver X-ray Conference. His contributions include methods for residual stress measurement, X-ray depth profiling, and determining plastic deformation in metals, ceramics, biomaterials, polymers and their composites.

The 2011 Jerome B. Cohen Student Award was given to Vallerie Ann Innis-Samson, University of Tsukuba, Ibaraki, Japan, for her work, X-ray Reflection Tomography: A New Tool for Surface Imaging. The award recognizes the outstanding achievements of student research in the field of X-ray analysis.

Social events were also held during conference week. PANalytical and ICDD sponsored the Monday evening poster session and Wine & Cheese Reception. The “Wild West” themed evening included a whiskey tasting contest using PANalytical’s Epsilon 3XL instrument with attendees trying to beat the machine to identify different brands of whiskey. Tuesday evening’s reception and poster session was hosted by the conference’s Premier Sponsor, Chemplex Industries, Inc. ICDD sponsored an anniversary party in the exhibit hall on Wednesday evening, celebrating 25 years of the Powder Diffraction Journal, 60 years of the Denver X-ray Conference and 70 years of ICDD. On Thursday evening, an off-site event was held for a night of baseball, food and fun. Attendees reveled in America’s favorite pastime, watching the Colorado Sky Sox play the Nashville Sounds. Although the home team did not win, everyone enjoyed the camaraderie and excitement of the evening.

The Organizing Committee would like to acknowledge the workshop chairs and instructors, invited speakers and session chairs for all the time and effort they volunteered to make this conference a great success. They would also like to send their appreciation to Chemplex and PANalytical for supporting the poster sessions. For a preview of the 2012 Program, visit
