The influence of Alloying on slip intermittency and the implications for dwell fatigue in titanium
The high precision of HEDM measurements at FAST offer new insight into the microscopic processes that cause dwell fatigue, pointing toward new alloying strategies for mitigation.
A New Robotic Arm at the Structural Materials Beamline
SMB is one of two beamlines at the Materials Solutions Network at CHESS (MSN-C) providing critical infrastructure in support of materials research for the U.S. Department of Defense. SMB is optimized for the study of structural materials – materials that can sustain a load or withstand an impact such as engineering alloys and composites.
Alongside enormous construction project, CHESS restarts to deliver beam to users.
Throw in a $28M construction project and a few routine upgrades, and there are bound to be more challenges, particularly unearthing a portion of the storage ring and tapping three new beamline holes into the Cornell Electron Storage Ring, CESR. These three new connections - and the large construction project they accompany - are all part of the New Experimental Hall. This ongoing construction project at Wilson Lab will house the High Magnetic Field Beamline and up to four additional beamlines.

Turning Heroic Efforts Into Everyday Experiments
The challenge now is to efficiently use these expensive techniques - and the enormous datasets they produce - to better understand existing problems and gain insight into new phenomena that have been previously unreachable.
CHESS has been at the heart of this explosive growth, and will now develop new, efficient experimental and data processing protocols for using these techniques.

Protein family shows how life adapted to oxygen
Cornell scientists have created an evolutionary model that connects organisms living in today’s oxygen-rich atmosphere to a time, billions of years ago, when Earth’s atmosphere had little oxygen.
CHESS Welcomes New Staff Scientist - Steve Meisburger
Steve is very interested in structural biology methods that let us see "molecular movies" -- i.e. how molecular machines like enzymes actually work. Diffuse scattering is one such method that he’s worked on with Nozomi Ando's group. But he’s also interested in using time-resolved techniques to include more types of perturbations, such as temperature, pressure, and electric fields.
CHEXS Lending Library offers valuable teaching resource
The CHEX Lending Library is a far-reaching program. In the past year, a total of 3,560 students have used our kits including 1,011 underrepresented minority students and 1,770 female students. The Lending Library provides students with the opportunity to interact with lessons and kits they would not otherwise have access to.
Rebecca, an experienced teacher at Cortland High School in New York State, sent us a heartfelt thank you note (after implementing the DNA Profiling Lab) that read in part:
Nanocrystals with Metastable High-Pressure Phases Under Ambient Conditions
Several spectroscopy techniques are implemented at CHESS for in-situ monitoring of materials properties, enabling simultaneous build-up of materials structure-property relations under real environments.
