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.
CHESS Director Earns Cornell Engineering Research Excellence Award
Powerful X-rays, energy tech, wireless electric-vehicle charging, big data, swarming robots, and cryo-electron microscopy are among some of the research themes that helped six faculty members earn Cornell Engineering Research Excellence Awards – the highest research honor given by the Ivy League’s top-ranked engineering college.
Wild blue wonder: X-ray beam explores food color protein
A natural food colorant called phycocyanin provides a fun, vivid blue in soft drinks, but it is unstable on grocery shelves. Cornell’s synchrotron is helping to steady it.
CHESS Welcomes Greg Ray as New Director of Strategic Partnerships
Greg Ray has been named the new Director of Strategic Partnerships at the Cornell High Energy Synchrotoron Source. In his role, Greg will work closely with the CHESS Director and Senior Leadership Team to provide strategic guidance, and interface with multiple partner organizations – creating and maintaining long-term relationships with external organizations and funding partners.
In situ SAXS/WAXS mapping of thermoplastic crystallization during 3D printing
AFRL and Boeing collaborate with CHESS to enable real-time measurements of high performance thermoplastics in 3D printing composites processing.
Assessment of DFT methods for geometry optimization of platinum-containing complexes
In a new publication, the team of Louise Debefve and Chris Pollock (both at the PIPOXS beamline at CHEXS) have evaluated 80 different DFT methods to reproduce the experimental geometries of Pt complexes, using a diverse training set of 14 platinum-containing species with varying sizes, oxidation states, and number and type of ligands.
Testing for the Continuous Spectrum of X-Rays Predicted to Accompany the Photoejection of an Atomic Inner Shell Electron
Echoing classical physics, quantum electrodynamics predicts the release of a spectral continuum of electromagnetic radiation upon the sudden acceleration of charged particles in quantum matter. Despite apparent theoretical success in describing sister nuclear processes, known as internal bremsstrahlung, following nuclear beta decay and K capture, the situation of the photoejection of an electron from an inner shell of an atom, intraatomic bremsstrahlung (IAB), is far from settled.
