    In recent decades, the phenomena of anomalous diffusion have been observed in many physical systems, e.g., pollutant transport through porous media, water transfer in soil and underground water, electron transfer in semiconductor and nuclear proliferation. The study of anomalous diffusion is also of special significance in chemistry, biology, environmental science, even in economics. However, in complex diffusion modeling, there are still some perplexing open research issues which are not well settled, such as
(1) The diffusion processes which change with time evolution, spatial position or system parameters; it maybe require the variable-order diffusion models.
(2) The diffusion processes in the inhomogeneous medium;
(3) The multi-scale diffusion process which involves both diffusion in mobile and immobile media.
(4) The anomalous diffusion processes under an oscillating external field.
(5) Power law phenomena and its statistical characterization.
