Figure 1: Ni–Co particles before and after complete oxidation in air.

From: Interrogation of bimetallic particle oxidation in three dimensions at the nanoscale

Figure 1

(a,c) HAADF-STEM tomographic reconstructions of the particles before and after oxidation, respectively. (b,d) EELS maps of the spatial distribution of cobalt and nickel in different nanoparticles (b) before and (d) after oxidation. Plural inelastic scattering was removed from the EELS spectra to exclude the influence of thickness differences. Scale bar, 50 nm.
