3D reconstruction of cuboctahedral shape particles, from images obtained at different tilt angles relative to the electron beam, after 40 iterations (see Methods). (a) Nanocube cluster. Neighboring nanocubes have {100} surfaces face to face separated by a distance above 2 nm due to hydrocarbon ligands. (b) Single nanocube in its original context. (c) Illustration of small deviations from perfect cubic symmetry.
