    Partially oxidized Ni 2p spectrum fitted through the Block Approach (Ni 2p forum)

    The spectra were obtained from the surface of a metallic nickel thick sample exposed to UHP O2 at 100°C for 8 min in a tubular furnace. The spectra were fitted through the block approach* and are displayed normalized. The main peak (shown in olive green) corresponds to the metallic component; the five doublets are associated to the oxide components. Data included in a Master Degree Thesis (Guzmán-Bucio et al. "Oxidation mechanism of metallic nickel," to be published). * A. Herrera-Gómez, F.S. Aguirre-Tostado, Y. Sun, P. Pianetta, Z. Yu, D. Marshall, R. Droopad, W.E.
