Darren Pagan awarded AFRL grant
Former CHESS Staff Scientist Darren Pagan has been awarded a Young Investigator Research Program grant through the Air Force Office of Scientific Research (AFOSR).
Congratulations to Jacob Ruff, New Director of CHEXS
Jacob Ruff has been named the new director of the Center for High-Energy X-ray Sciences at CHESS (CHEXS @ CHESS). In his role, Jacob will lead research at the five beamlines of CHEXS while supporting education and training, particularly of researchers in biological sciences, engineering, and materials research.
In-situ high energy X-ray diffraction probes elastic response of metastable engineered alloys
Recent research at CHESS provides a framework by which the single crystal elastic constants of complex alloys can be determined experimentally in a straightforward manner.
Validation of Welding Model for Digital Twin of Thick-Plate Joint: Mapping Residual Strains in HSLA Steel using High Energy X-rays
The U.S. Navy is seeking to establish digital twin prototypes across the Fleet. A digital twin is a virtual model of a process, product, or service which seeks to pair the virtual and physical world to enable data analysis and system monitoring. A key driver of this digital effort for the materials community is to integrate materials and manufacturing process information with component-level performance and lifecycle analysis. This effort requires accurate material property inputs for simulations, which must be obtained from real materials.
Breakdown of the Small-Polaron Hopping Model in Higher-Order Spinels
The authors present an updated “small-polaron hopping model” to include contributions of decoupled pathways for the flow of electrons in spinel oxides. Their work provides a route for custom-tailoring the properties of oxides used in technologies such as fuel cells, batteries, and solar cells.
CHESS receives $32.6M from NSF for new X-ray beamline
The National Science Foundation has awarded the Cornell High Energy Synchrotron Source (CHESS) $32.6 million to build a High Magnetic Field (HMF) beamline, which will allow researchers to conduct precision X-ray studies of materials in persistent magnetic fields that exceed those available at any other synchrotron.
X-rays uncover “hidden” quantum states
Quantum materials research involves manipulating and measuring the collective quantum states of electrons in materials. The NSF-funded user facilities at CHESS and the National High Magnetic Field Laboratory (aka the MagLab) have long been important resources in this pursuit.
CHESS Restarts for Remote Research
The Cornell High Energy Synchrotron Source, CHESS, has reopened for researchers after a long shutdown due to CoVID-19. Users who typically travel from all over the world to perform research at CHESS are now able to study their samples by logging in remotely from their home institutions.
