The images that follow were created by researchers and students working in Drexel’s Centralized Research Facilities, using electron microscopes that can achieve magnifications that would scale a grain of sand up to the size of a football stadium. The images, taken at the nano-scale, do not actually have any color; the colorization here was added by Drexel researchers for dramatic effect, creating images that live at the peculiar intersection of science and art.

Fractured surface of a nanocrystalline magnesium matrix composite reinforced with Ti2AlC. A Ti2AlC grain kinked several times during fracture to form a “dragon.” The width of image is 3µm.
