Fig. 9

Simulated EDX maps of Pt monolayer nanoparticles viewed a along a 110 zone axis, b tilted by 5° away from a 110 zone axis and c tilted by 10° away from a 110 zone axis. The intensity in b and c has been doubled to make the figures visible on the same intensity scale as the on-axis map (a). Corresponding line profiles taken vertically through the centre of the nanoparticle are shown in d, e and f, assuming a dwell time of 1 s per point and a pixel width of 15 pm. The Pt-L signal is shown in red, while the Ni-K signal is shown in green. The distance used here to measure the shell thickness is highlighted by the black arrows
