based on the linearized Navier-Stokes equation for an incompressible fluid. Here r is a vector pointing at any position within the periodic particle/solvent system, k are reciprocal lattice vectors, ⊗ denotes a dyadic product, η the viscosity, V the Volume, and 1 is the unity matrix. By adapting the Kirkwood-Riseman theory of polymer diffusion , and employing the Oseen tensor for an infinite nonperiodic system T 0 (r
