      abstract     = {The impact of faceting on grain growth was approached by
                      model experiments in NiO–MgO. Grain growth rates were
                      found to be 10 times higher in NiO compared to MgO. As the
                      self-diffusion acoefficients differ by a factor of 250,
                      grain growth in NiO is unexpectedly slow compared to MgO.
                      Recently, the movement of steps was identified as the atomic
                      mechanism of grain boundary migration. According to the
                      equilibrium crystal shape, grain boundaries in NiO are more
                      faceted. The faceted grain boundaries of NiO have fewer
                      steps at the grain boundaries resulting in a relatively
                      lower mobility.},
