Freeze! Researchers develop new protein crystallography tool
Combining state-of-the-art X-ray technology and cryogenics, Cornell physics researchers have developed a new method for analyzing proteins in action, a breakthrough that will enable the study of far more proteins than is possible with current methods.
Summer Students: Live and In-Person
CHESS Summer students came together last month for their first - and only - in-person meeting of the summer. The group of students have been working remotely with their mentors since the start of the program on June 6th due to Covid-safety precautions.
Progress in high-pressure crystallography at ID7B2 furthers the mission of HP-Bio
Recent developments at station ID7B2, jointly operated by MacCHESS and the HP-Bio project of CHEXS, demonstrate the use of high-pressure crystallography to examine the response of macromolecules to changes in pressure.
Grain-scale deformation of a high entropy alloy using synchrotron high energy diffraction microscopy
New research that exploited the unique strengths of the FAST beamline produced some of the first measurements of individual grain deformation in high entropy alloys. This data can help form accurate predictions of damage and failure processes in these emerging materials, critical for understanding their performance in real-world applications.
In situ spectroscopy as a probe of electrocatalyst performance
Hydrogen fuel cells generally require expensive and scarce platinum catalysts in order to function. Researchers have created highly reactive platinum-nickel nanowires with the potential to reduce the amount of platinum required in fuel cells. Research at PIPOXS examines the atomic-level mechanisms of this catalyst, forming a foundation for the development and commercialization of more efficient fuel cell technology.
ACA honors staff scientist Richard Gillilan
Richard Gillilan, a MacCHESS/CHEXS staff scientist, has been named a member of the 2021 class of Fellows of the American Crystallographic Association (ACA), in recognition of his many career achievements.
Unconventional chiral charge order in kagome superconductor KV3Sb5
Intertwining quantum order and non-trivial topology is at the frontier of condensed matter physics. In a new paper appearing in the journal Nature Materials, a team lead by M. Zahid Hasan from Princeton University reports the discovery of an unconventional chiral charge order in a kagome material, KV3Sb5.
In-Hutch Commissioning of Rotation and Axial Motion System IV (RAMS IV) Load Frame
In spring 2021, the fourth generation of Rotation and Axial Motion System (RAMS IV) load frame was commissioned with X-rays at the Structural Materials Beamline (SMB).
