title: Knudsen diffusion and surface trapping rates in slit, capillary, and spherical pores.
abstract: De Gennes model for Knudsen diffusion and strong surface trapping kinetics is applied to slit, capillary, and spherical pores. The exact analytical survival probability-time expressions obtained for each case, which scale with the average pore diameter, are compared with numerical simulation curves for a densely packed hard sphere model porous bed.
