Researchers from the University of Michigan, the University of California at Berkeley, Cornell University, the U.S. Department of Energy’s Argonne National Laboratory and Lawrence Berkeley National Laboratory (Berkeley Lab), and Dow Chemical have accomplished high-resolution, efficient 3D chemical imaging for the first time at the one-nanometer scale. Up to this point, nanomaterial researchers have had to choose between imaging 3D structure or 2D chemical distribution. This time, the researchers developed a process to collect 3D images at every tilt angle as well as chemical images every few tilts. A multi-modal algorithm then takes the information for both signal types and outputs the 3D structure and chemistry. This research work was done in part at the Molecular Foundry, a nanoscience user facility that is part of Berkeley Lab.
