Fermi Surface Mapping and Charge-Density-Wave Order in the Kagome Superconductor CsV3Sb5
Using a combination of synchrotron x-rays, quantum oscillations, and density functional theory, researchers have demonstrated a substantial reconstruction of the Fermi surface pockets associated with the vanadium orbitals due to the charge-density-wave.
Evolution of the Microstructure of Laser Powder Bed Fusion Ti-6Al-4V During Post-Build Heat Treatment
Ti64 components made via additive manufacturing typically exhibit poor structural properties arising from a non-equilibrium microstructure which forms under rapid cooling. The goal of the research reported here is to understand and design post-build heat treatments that can restore the desired structural properties to additively manufactured components. If a heat treatment procedure can be found which recreates the as-wrought microstructure, it would enable cost-effective advanced manufacturing of complex components in the future.
X-ray technique offers new view inside active batteries
A new X-ray technique developed at Cornell offers an unprecedented look at the elaborate inner workings of batteries while they are in use – a breakthrough that is already yielding important findings for the development of next-generation energy storage.
AI powers autonomous materials discovery
SARA (the Scientific Autonomous Reasoning Agent) integrates robotic materials synthesis and characterization, along with a hierarchy of artificial intelligence and active learning methods, to efficiently reveal the structure of complex processing phase diagrams, making materials discovery vastly quicker.
Message from the Director
The next run starts January 26th, and all CHESS beamlines will be operating. Whether experiments will be done in-person or will have to be remote is yet to be seen.
Internship enhances diverse skillset for SUNY Delhi Mechatronics interns
Alex Adams and Ryan Ford, two SUNY Delhi mechatronics majors, are wrapping up six-month long internships at CHESS. The two seniors have contributed to and led a number of projects, creating a lasting impact on the experiments at the lab.
CHESS user Aeriel Murphy-Leonard shares #LightSourceSelfie
Scientists and engineers from 25 facilities across the global light source community have contributed to #LightSourceSelfies, a video campaign to inspire and inform all those with a curiosity for careers connected to synchrotrons and Free Electron Lasers (FELs).
BioSAXS helps to explain the anti-cancer activity of green tea
EGCG, a polyphenol compound found in green tea, has a proven anti-cancer effect. Studies now suggest that EGCG works by binding to the potent anti-tumor protein p53 and stabilizing it, so that its activity against cancer is increased. Several experiments, including BioSAXS at CHESS ID7A, support this conclusion.
