Carbon Nanospheres (IMAGE) Ecole Polytechnique Fédérale de Lausanne Caption This is a superposed, tilt-less electron microscopy stereo image (color-filtered) of carbon nanospheres decorated with nanoparticles. The same structures appear in red and blue and the nanoparticles are slightly shifted according to their 3-D distribution in the carbon sphere. This image shows the applicability of the new tilt-less 3-D imaging techniques to other structures.
