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.
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.
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.
Super Cornell Compact Undulator (sCCU) Compact Variable-Gap Undulator with Hydraulic-Assist Driver and Enhanced Magnetic Field
A team at CHESS in collaboration with PHAD has developed, prototyped, built, and tested a compact variable-gap undulator with hydraulic-assist driver and innovative hybrid magnetic structure.
