The Materials Solutions Network at CHESS (MSN-C) was leveraged to map strains using non-destructive x-ray methods not available at other USAF, Department of Defense, or private sector facilities. The high-flux and high-energy x-rays only available at a synchrotron light source, such as CHESS, enable a critical combination of high penetrating power, spatial resolution and measurement speed. This highlight is just one example of how MSN-C is permitting new, systematic studies of structural materials.

What did the scientists accomplish?

Ando has dedicated her career to “seeing” atoms using high energy X-rays with a technique called diffuse scattering; imagine a pair of glasses that allow you to see atoms and molecules. These glasses not only let you see these molecules but also very specific ways molecules move.

The group’s paper, “Dendritic Deformation Modes in Additive Manufacturing Revealed by Operando X-Ray Diffraction,” published Oct. 10 in Nature Communications Materials. The lead author is doctoral student Adrita Dass, M.S. ’20.

Doctoral students Adrita Dass (left) and Chenxi Tian, and Atieh Moridi, assistant professor in the Sibley School of Mechanical and Aerospace Engineering, created a portable twin of their 3D-printing setup.

Prof Bawendi is an international leader in quantum dot synthesis and characterization, as well as a valued past CHESS user and collaborator. We congratulate his entire team on the well-deserved recognition of their decades of groundbreaking research. We encourage the CHESS user community to take a moment to acknowledge this milestone by revisiting some classic papers from Prof Bawendi, and/or his current and former students and postdocs, which made use of the CHESS facility:

Magneto-Fluorescent Core-Shell Supernanoparticles

Funded with a $5 million grant from the Defense Manufacturing Community Support Program run by the U.S. Department of Defense and $1.8 million from Cornell, the consortium is a collaborative effort led by Cornell’s Sibley School of Mechanical and Aerospace Engineering in partnership with the Cornell High Energy Synchrotron Source (CHESS) and the Cornell Center for Materials Research (CCMR).

Q: Could you tell me a little bit about your initial experience as a community college student in the SERCCS program at CLASSE?
