Imaging a Mesostructured Silicon Particle (IMAGE) University of Chicago Caption These images show a mesostructured silicon particle. Left: transmission X-ray microscopy 3D data set of one region, suggesting spongy structures. The purple square measures 8.28 microns along the top edges, which is much less than the width of a human hair. Right: transmission electron microscopy image showing an ordered nanowire array. The 100-nanometer scale bar is 1,000 times narrower than a hair. Credit Tian Lab.
