Where did those electrons go? X-ray measurements solve decades-old mystery

ITHACA, N.Y. – The concept of “valence” – the ability of a particular atom to combine with other atoms by exchanging electrons – is one of the cornerstones of modern chemistry and solid-state physics. Valence controls crucial properties of molecules and materials, including their bonding, crystal structure, and electronic and magnetic properties. Four decades ago, […]

Cornell sheds high-energy X-ray light on Caterpillar’s welding technique

ITHACA, N.Y. – Heavy equipment maker Caterpillar Inc. partnered with Cornell University’s Cornell High Energy Synchrotron Source (CHESS) to test Caterpillar’s computer modeling and improve the firm’s welding technique. The Illinois-based corporation is the first industry user for one of CHESS’s newest initiatives: InSitµ@CHESS, a center that provides user support for structural-materials analysis using CHESS’s […]

Imaging technology reveals copper is key to meeting future food and energy needs

Media Note: Images can be viewed and downloaded at https://cornell.box.com/v/plants. ITHACA, N.Y. – For the first time, Cornell University researchers are using imaging capabilities at the Cornell High Energy Synchrotron Source (CHESS) to explore how copper affects plant fertility. The work could provide key insights into how plants can be bred for better performance in […]

Energy-efficient accelerator was 50 years in the making

ITHACA, N.Y. – With the introduction of CBETA, the Cornell-Brookhaven ERL Test Accelerator, Cornell University and Brookhaven National Laboratory scientists are following up on the concept of energy-recovering particle accelerators first introduced by physicist Maury Tigner at Cornell more than 50 years ago. CBETA tests two energy-saving technologies for accelerators: energy recovery and permanent magnets. […]

Out of the blue: Cornell X-ray finds unique fingerprint in Medieval manuscript ink

Media Note: Images of the manuscript and testing process can be viewed and downloaded at https://cornell.box.com/v/CHESSmanuscript. ITHACA, N.Y. – Analyzing pigments in medieval illuminated manuscript pages at the Cornell High Energy Synchrotron Source(CHESS) is opening up some new areas of research bridging the arts and sciences. Louisa Smieska and Ruth Mullett studied manuscript pages from Cornell […]

Bringing bacteria’s defense into focus

ITHACA, N.Y. – By taking a series of near-atomic resolution snapshots, Cornell University and Harvard Medical School scientists have observed step-by-step how bacteria defend against foreign invaders such as bacteriophage, a virus that infects bacteria. The process they observed uses CRISPR (clustered regularly interspaced short palindromic repeats) sites, where the cell’s DNA can be snipped […]

Crystallization plate provides clues on protein structure aboard historic space mission

ITHACA, N.Y. – A new crystallization plate, developed and tested at the Cornell High Energy Synchrotron Source, or CHESS, hitched a ride to outer space and is helping a major drugmaker learn about protein structure. The In-Situ-1 crystallization plate – developed by Robert Thorne, professor of physics at Cornell University, and the company he founded, […]
