On June 5, 2024, the inaugural Cyberinfrastructure Training and Education for Synchrotron X-ray Science (X-CITE) workshop at CHESS concluded with resounding success, welcoming 63 participants from 15 different institutions and marking a significant milestone in the ongoing effort to enhance cybertraining for CHESS users. 

In a new publication from a team of CHEXS users from the New Jersey Institute of Technology and the Johns Hopkins University, the interaction between ESD-generated mild shockwaves and a set of particles in the micrometer size range was studied using high speed X-ray imaging at the FAST beamline.

"In a recent paper appearing in the journal Physical Review Materials, a team of CHEXS users from UCSB and Cornell was able to resolve this apparent contradiction by comprehensively mapping the subtle charge correlations in ScV6Sn6 as a function of temperature at the QM2 beamline."

As scientists continue to discover new niches for extreme life, the biological relevance of hydrostatic pressure is becoming much more widely understood and appreciated. The unusual adaptations of organisms thriving under these conditions promise to be a rich source of new insights, provided structural information can be obtained at the molecular level. CHESS is at the forefront of this research - enabling scientists to study samples under high pressure, revealing how biomolecules and cellular structures behave in extreme environments.

In a new paper appearing in Communications Biology, prof. Daniel Keedy's group from the CUNY Advanced Science Research Center used x-ray crystallography at CHESS to investigate the conformation changes of a medically-important biomolecule (the protein tyrosine phosphatase enzyme STEP) when perturbed by pressure and temperature.

CHESS celebrated its annual User Meeting with the theme "Cultivating Community," emphasizing the integral role of CHESS users, researchers, technical staff, and scientific staff. The 2024 User Meeting attracted over 150 attendees who gathered for a day of scientific talks, facility updates, awards, and a vibrant poster session. See the Photo Gallery here!  

The Cornell Laboratory for Accelerator-based Sciences and Education (CLASSE) funds summer research opportunities in the areas of x-ray and accelerator sciences, materials science, chemistry, and mechanical engineering for pre-selected undergraduate students from primarily undergraduate institutions and minority serving institutions. This summer, twenty REU students are hosted by CLASSE. Ten students from the CHESS summer programs -- SERCCS, PREM, and SUNRiSE -- are jumping into their rigorous summer undergraduate research experience.

Now, in a new paper appearing in the journal “Chemistry of Materials”, a group of researchers from Oak Ridge National Laboratory, Argonne National Laboratory, and CHEXS use high-energy x-ray spectroscopy to gain fundamental insights into the redox processes and migration tendencies of transition metals in the cathode material 0.7(Li2MnO3)·0.3(LiFeO2).
