| Abstract: | The possible formation of statistical pores through black lipid membranes may constitute a new mechanism for the explanation of transversal diffusion of lipid molecules through bilayers. In this work, we calculate the flip-flop diffusion coeficient, which is related to the mean number of statistical pores formed on the planar bilayer and the lateral diffusion coeficient. Its approximately calculated value is: Dff = 10−3 m2 s−1. |
