A superlattice pattern composed of In2O3 nanoctahedra and Pd spherical nanoparticles, assembled by opposite electrical charges. (a) TEM image; (b) reconstructed volume rendering; (c) close to edge-on side view of the volume; (d) edge-on side view of the volume. It is revealed that most of the Pd NPs locate on the middle plane of the In2O3 nanoctahedra well above the substrate surface (support film), rather than sitting on it. Images were taken by Dr. Zhiping Luo, and published on ACS Nano(4), 1821-1828 (2010).[Abstract]  [Full text HTML]  [PDF]
