  text: 'The reaction between NiO and (0001)- and ([1\bar102])-oriented Al2O3 single
    crystals has been investigated on model experimental systems by using the ReflEXAFS
    technique. Depth-sensitive information is obtained by collecting data above and
    below the critical angle for total reflection. A systematic protocol for data
    analysis, based on the recently developed CARD code, was implemented, and a detailed
    description of the reactive systems was obtained. In particular, for ([1\bar102])-oriented
    Al2O3, the reaction with NiO is almost complete after heating for 6 h at 1273 K,
    and an almost uniform layer of spinel is found below a mixed (NiO + spinel) layer
    at the very upmost part of the sample. In the case of the (0001)-oriented Al2O3,
    for the same temperature and heating time, the reaction shows a lower advancement
    degree and a residual fraction of at least 30% NiO is detected in the ReflEXAFS
    spectra. '
