Diffusion example 5. Mean squared displacement of a tracer molecule in 3 different systems where the 30 % of the total lattice space is occupied by the same type of crowder molecules, but having different radii: 23 873 molecules of r crowder  = 2 nm, or 42 441 molecules of r crowder  = 1.5 nm, or 95 493 molecules of r crowder  = 1 nm). The radii and concentration of the tracer are 1.5 nm and 1 414 molecules, respectively. The parameters used in the simulation are indicated in Table 1
