Now, in a new paper appearing in the Journal of the American Chemical Society, a team of researchers from Cornell and the University of Wisconsin report new catalysts which exhibit superior ORR activity and robust stability. The team has characterized metal–organic framework-derived nonprecious dual metal single-atom catalysts (SACs), consisting of Co–N4 and Zn–N4 local structures.
What is the discovery?
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.
The CHESS Lending Library is a scientific equipment loan program hosted by the Cornell High Energy Synchrotron Source that provides free hands-on experiment kits for empowering teachers and engaging students in high quality labs. Kits are designed for specific scientific fields such as biology, chemistry, and physics as well as different age groups including elementary, middle, and high school grade levels.

Cornell University's High Energy Synchrotron Source (CHESS) recently hosted a multi-day workshop on High Energy X-ray Techniques (HEXT) from May 16 to 17, 2023. The workshop was funded by the National Science Foundation and aimed to introduce students from the Partnership for Research and Education in Materials (PREM) program to synchrotron methods, emphasizing their applications to a wide variety of research questions.
The development, outlined in a paper published March 3 in Nature Communications, provides researchers with the tools to interpret the once-discarded data from X-ray crystallography experiments – an essential method used to study the structures of proteins. This work, which builds on a study released in 2020, could lead to a better understanding of a protein’s movement, structure and overall function.
