3-D Atomic Structure of a Decahedral Multiply Twinned Platinum Nanoparticle (video) Northwestern University Share Print E-Mail Loading video... Caption Three-dimensional volume renderings of the platinum nanoparticle are reconstructed from 104 experimental projections in which nearly all the atoms of the nanoparticle are visible. Furthermore, 3-D atomic steps at twin boundaries and the 3-D core structure of edge and screw dislocations in the nanoparticle are observed at atomic resolution. (See Figures 2-4 in the paper.) These dislocations and the atomic steps at the twin boundaries, which appear to be stress-relief mechanisms, are not visible in conventional 2-D projections.
