Protein unfolded states populated at high and ambient pressure are similarly compact
This is perhaps the first reported study of the temperature dependence of the dimensions of the high pressure unfolded state of a protein. These measurements strongly support the notion that pressure unfolded proteins do not differ significantly from proteins which are unfolded at atmospheric pressure.
Next-generation detectors ready for experiments at CHESS
Sydor and the Cornell Detector Group worked with CHESS staff and users throughout both the original and commercial development of these new detectors, where CHESS served as a crucial venue for system testing.
Now, Sydor aims to identify a few target user experiments at CHESS where researchers are interested in pushing the detectors to their limits.
CHESS Scientists and Outreach take part in Expanding Your Horizons 2021
Since 1988 the annual Expanding Your Horizons (EYH) conference has been encouraging curious youth to pursue their interests in science, technology, engineering, and maths (STEM). This year three CHESS staff contributed to the virtual event.
PREM connection, operando research lead to ACS Award for CHESS User
Mario Ramos-Garcés, CHESS User and former Ph.D. student at UPR-Río Piedras has been honored by the American Chemical Society's Division of Inorganic Chemistry with the Young Investigator Award for his Ph.D. research.
Investigation of porosity, texture, and deformation behavior using high energy X-rays during in-situ tensile loading in additively manufactured 316L stainless steel
A high-energy x-ray study of 316L stainless steel produced by laser powder bed fusion used x-ray tomography to understand porosity in the manufactured samples, and then observe the effect of these pores on the evolution of damage, texture, and strain when the materials are mechanically deformed.
Autonomous materials development using in situ laser annealing and scan-probe, grazing incident x-ray microdiffraction.
During the 2021-1 run cycle at the FMB-beamline of MSN-C, an interdisciplinary group of researchers based at Cornell University demonstrated the first use of an AI-directed, fully-automated process for thin-film metastable materials exploration.
A virus recognizes the starting point on the DNA to be packaged inside its protein shell
A bacteriophage – a virus that attacks bacteria – assembles into an infectious species using a powerful nanomachine to stuff its DNA into a protein shell. In several types of phage, this genome packaging motor is composed of several copies of large and small terminase subunits (TerL and TerS, respectively) that attach to a portal into the protein procapsid.
Incommensurate charge order in a low-dimensional superconductor
A team lead by Sara Haravifard from Duke University has conclusively and directly identified the subtle charge density wave phase in TPT emerging below 12K. The CDW couples to the superconducting transition and is suppressed by pressure at a critical point that maximizes the superconducting Tc. The promise of engineered high temperature superconducting materials, which could revolutionize computing, energy, and transportation industries, drives ongoing fundamental research into the interplay between SC and CDW order.
