Location, Dates & Attendance
The Denver X-ray Conference [DXC] returned to its home state of Colorado in 2018. The conference was held at the Westin Hotel in Westminster, Colorado, a short drive north of Denver, during the week of August 6 – 10. It was the 67th consecutive year that the Annual Conference on Applications of X-ray Analysis took place, hosting close to 300 registered attendees and 150 exhibit personnel. X-ray and materials scientists gathered at the conference to discuss various techniques, applications, software, instruments and products for XRD and XRF analysis. The combination of attendees and exhibitors brought the total attendance to over 400 X-ray scientists, with 30% from outside the United States.

The technical program began with 17 half-day tutorial workshops held on Monday and Tuesday of conference week. Topics were categorized as either XRD, XRF or Special Topic, and focused on both beginner and advanced levels. Forty-five specialists were invited to participate as workshop instructors, and many provided handouts that were posted on a private website for attendees only.

Plenary Session
The Plenary Session, Minerals and Gems, was held on Wednesday morning, as the opening session for the oral talks that would be presented the next two days of conference week. The plenary was chaired by Tom Blanton, International Centre for Diffraction Data, and began with an awards presentation. The Birks Award, given biennially to recognize outstanding contributions to the field of X-ray spectrometry, was presented to Christina Streli of the Atominstitut, Technical University Wien, Austria. Dr. Streli received the award for her contributions to the development and applications in the field of X-ray fluorescence spectrometry including TXRF, micro XRF, confocal XRF, and 2D and 3D chemical imaging for a better understanding of complex problems; and for her commitment to her students and the international XRF community.

In addition to the Birks Award, the 2018 Robert L. Snyder Student Award grants were presented during the plenary session to seven outstanding young scientists. The awardees and the works they presented at the conference were:

In Situ Monitoring of the Crystallization of Amorphous Solid Dispersions in Aqueous Solution, using Synchrotron Radiation
K. Konadu Amponsah-Efah, University of Minnesota, USA

A Straightforward Program Written in Octave and Julia for X-ray Diffraction Line Profile Analysis: A Study in Gold Thin Films

Following the awards presentation, the plenary session continued with two fascinating talks by renowned keynote speakers David Bish, Indiana University, USA and Aaron Celestian, Natural History Museum of LA, USA. Dr. Bish presented the talk, Using X-ray Diffraction to Elucidate Source Materials and Firing Conditions of Pompeian Ceramics, followed by Dr. Celestian’s presentation on, Collaborative Mineralogical Research in Museums. The session was well attended, and received many positive comments from attendees.

Special Sessions
From Wednesday afternoon until Friday morning, fifteen half-day oral sessions were held. Nearly 200 presentations were organized in the oral sessions, with twenty-six of the presentations given by invited speakers, experts in their respective fields. Included was a special session and open group discussion on Advanced Fundamental Parameters, which served as the annual meeting for the International Initiative on X-ray Fundamental Parameters. The FP initiative has met annually since 2008, and attracts attendees from national metrology institutes, academic institutions, and industry. Joel Ullom of NIST, USA served as Chair for the special interest group.

Poster Sessions
Posters were presented on Monday and Tuesday evening during the XRD and XRF poster sessions. Two E-poster stations were also set-up in the exhibit hall. Attendees were given the opportunity to study electronic copies of the posters at the E-poster stations, or through the mobile app, Guidebook. Best poster awards were chosen, and the competition was intense. Ultimately, the following presenters were named winners:

The exhibit hall accommodated 44 companies with displays of products and services for the X-ray community. A complete listing of exhibitors and their product descriptions can still be found on the conference website:

Social Event and Sponsorships
The conference was fortunate to have many generous companies offer their financial support as sponsors. Bruker once again reigned as Platinum Sponsor of the DXC, inviting every attendee, exhibitor, and guest to a murder mystery dinner in the mountains, complete with tasty foods, abundant libations, music, and prizes. Silver sponsorships were received from Chemplex Industries, Inc., DECTRIS Ltd., KETEK and Proto. The generosity of our sponsors helps to keep attendee costs low, and the quality of the conference high. We are grateful for their support!
