13. f(D) where k is a prefactor and f(D) is a simple function of D, shows that fit of data to such a law is usually limited to two orders of magnitude. In heterogeneous catalysis, fractality may have its origin in the non-equilibrium growth models (such as aggregation) of the materials which lead to power-law scaling behaviour on all scales of materials.
