Web4 jun. 1998 · When a sodium ion is added it tends to lie in the center of the channel where it can form the most complete solvation shell. Its diffusion rate decreases in smaller channels until it moves too slowly in a channel of 2 Å radius to be detected in our simulations. This decrease is only partly due to an increase in the mean square force on the ion.
