Step-by-Step: Revealing the mechanism of a protein-cleaving enzyme by crystallographic snapshots
"These unusual enzymes have been implicated in diseases ranging from Alzheimer’s disease to malaria, type II diabetes, cancer, Parkinson’s disease, cholera and tuberculosis."
Nearest neighbors and beyond: Reciprocal space imaging of ionic correlations in intercalation compounds
"The ability to generate a real-space ‘image’ of interatomic vectors from reciprocal space data, makes this technique a powerful tool in the investigation of intercalation compounds, "
CHESS Hosts Workshop on Advanced Manufacturing of Engineering Alloys
CHESS, especially the NSF-funded Center for High Energy X-ray Sciences (CHEXS) at CHESS and the Materials Solution Network at CHESS (MSN-C) supported by the Air Force Research Laboratory (AFRL), recently hosted the workshop “Methods for Characterizing Defects in Advanced Manufacturing Processes” jointly with Los Alamos National Laboratory (LANL).
The driving force behind Cornell Compact Undulators at CHESS
Researchers at CHESS are working to further improve the already impressive CHESS Compact Undulator, or CCU. Within the new NSF-funded CHEXS award, Sasha Temnykh is developing a new driving mechanisms that will add variable gap control and even better tuning of the device, both desirable qualities for a variety of experimental needs.
A Winning CHESS Opening
This October, the new user facilities at the Cornell High-Energy Synchrotron Source (CHESS) will open their doors to researchers. This opening follows a major upgrade project, known as CHESS-U, which establishes CHESS as one of the world’s leading X-ray sources.
Synergistic Co−Mn Oxide Catalyst for Oxygen Reduction Reactions
Researchers employed synchrotron-based X-ray absorption spectroscopy (XAS) at CHESS to investigate the synergistic interaction of bimetallic Co1.5Mn1.5O4/C catalysts under real-time operando electrochemical conditions.
Predicting and measuring residual stresses in additively manufactured components
"Researchers developed an advanced computational model to predict the residual stress state in a bridge shaped part and compared the simulated data with experimental results obtained at CHESS, finding good qualitative and quantitative agreement."
NSF Delegation visits CHESS
Last month, Linda Sapochack, NSF Division Director for the Division of Materials Research (DMR), Clark Cooper, Senior Advisor for Science and Head of the Office of Multidisciplinary Activities in the NSF Directorate for Mathematical and Physical Sciences, and NSF Program Director Guebre X. Tessema visited CHESS to see the newly upgraded facility.
