For structures determined by single particle cryo-EM, no technique currently exists for mapping elements to defined locations, leading to errors in the assignment of metals and other ions, cofactors, substrates, inhibitors, and lipids that play essential roles in activity and regulation. Elemental mapping in the…

Multi-elemental nanoalloys have shown significant promise in applications like catalysis, due to unique structural features that arise from their complex structure. A key feature of particular interest is local chemical order (LCO) at the scale of a single neighboring bond length. LCO has proven challenging and…
