From: Differentiating the structure of PtNi octahedral nanoparticles through combined ADF–EDX simulations
Simulated ADF STEM images and corresponding EDX maps of Pt-shell nanoparticle structure (1), viewed a, b along a ⟨100⟩ zone axis and d, e tilted by 5° from the ⟨100⟩ zone axis towards the ⟨110⟩ zone axis. The intensity in e has been doubled to make the figure visible on the same intensity scale as the on-axis map (b). Corresponding line profiles taken horizontally across the centre of the nanoparticle are shown in c and f, assuming a dwell time of 1 s per point and a pixel width of 11 pm. The Pt-L signal is shown in red, while the Ni-K signal is shown in green
