Plenary Session & DXC Awards

The Plenary Session, Energy Storage, was held on Wednesday morning as the opening session for the oral talks that were presented during the next three days of conference week. Scott Misture, Alfred University, chaired the plenary, which began with an awards presentation.

The Barrett Award

The Barrett Award, given biennially to recognize the outstanding contributions to the field of powder diffraction, was presented to Ashfia Huq of Sandia National Laboratories, USA. Dr. Huq received the award for her commitment to and leadership in the advancement of spallation neutron powder diffraction, and for her service to the neutron powder diffraction community.

The Jenkins Award

The Jenkins Award, given biennially to recognize scientists who exhibit lifetime achievement in the advancement of the use of X-rays in materials analysis, was presented to Tim Elam of University of Washington, USA. Dr. Elam received the award for his contributions to X-ray fluorescence spectrometry in the development of instrumentation and methods of X-ray analyses in challenging environments, including the PIXL micro-XRF spectrometer on the Mars rover Perseverance. The award also recognized his many contributions to educating and teaching others in the field of X-ray spectroscopy.

The Hanawalt Award

Also presented during the DXC Plenary Session was the 2022 ICDD Hanawalt Award, recognizing distinguished, recent work in the field of powder diffraction.
