First Crystal Structure at CHESS beamline ID7B2
In one of the first commissioning experiments since the upgrade of the facility, the team of Aaron Finke and collaborators measured the first crystal structure at CHESS beamline ID7B2. The beamline provided excellent quality data and a good refined structure from a fluoroacetate dehalogenase crystal was obtained as shown below. Further commissioning is underway. Even at this early stage, ID7B2 is definitely geared up to be a world-class beamline.
Relation of local order to material properties in ferroelectrics
Controlling and relating local order to macroscopic properties is key to materials engineering. By measuring large, three-dimensional volumes of X-ray diffuse scattering efficiently, we can now identify how different forms of local order correlate with dielectric and electromechanical properties as well as ordered polarized states.
Scientific Reports Journal Top 100
The Scientific Reports article on "Recovery of Degraded-Beyond-Recognition 19th Century Daguerreotypes with Rapid High Dynamic Range Elemental X-ray Fluorescence Imaging of Mercury L Emission" with X-ray fluorescence imaging at CHESS was identified to be among the top 100 highly accessed articles in Scientific Reports in 2018. Congratulations to the authors!
Synchrotron Essentials Workshop
On June 4- 5, 2019, students from several PREM groups and the INCREASE consortium participated in the CHESS User’s Meeting and the associated “Synchrotron Essentials” workshop.
Bioinspired membranes: Teaching an old dog new tricks
Living cells control input and output from the cell to the surrounding medium with highly specific channels formed by membrane proteins. In order to make this specificity available to membranes used in industrial separation processes, Suzana Nunes’ group at King Abdullah University of Science and Technology explored the behavior of block copolymers with a model peptide block.
CHESS Welcomes Elke Arenholz as New Associate Director
Elke Arenholz has been named the new associate director of the Cornell High Energy Synchrotoron Source. In her role, Elke will work closely with the CHESS Director to provide strategic guidance, to interface with multiple partner organizations, and to provide oversight and management of CHESS.
PREM students outfitting and upgrading CHESS x-ray beamlines
CHESS is fortunate to have three graduate students visiting from Puerto Rico. Supported by the NSF-PREM CiE2M – the Center for Interfacial Electrochemistry of Energy Materials – a partnership of The University of Puerto Rico, Rio PiedrasCampus (UPRRP), Universidad Metropolitana (UMET) and Universidad del Turabo (UT), and CHESS.
