Using a new x-ray imaging technique, scientists were able to get a
3-dimensional reconstruction of the Argonne National Laboratory logo with
a nanometer resolution from the surface layer of a sample. Figure A shows
an image produced with a scanning electron microscope (SEM), figure B
shows the Argonne logo and figure C shows the image as 2-D coherent surface scattering imaging (CSSI) data.
