LOTS CRYSTAL BALLS: This field of cadmium selenide crystals is what @argonne scientists discovered when they aimed a scanning electron microscope on one of their experiments to look at nanoscale level.
The entire field of view is just 500 microns across—the size of a period at the end of a sentence. Studying formations at the nanoscale helps scientists discover new materials for technologies like computer memory and solar cells. The image is of Superlattices of prolate CdSe nanocrystals on silicon wafer.
