      abstract     = {We present guidelines to estimate the effect of
                      electrostatic repulsion in sedimenting dilute particle
                      suspensions. Our results are based on combined Langevin
                      dynamics and lattice Boltzmann simulations for a range of
                      particle radii, Debye lengths and particle concentrations.
                      They show a simple relationship between the slope K of the
                      sedimentation velocity over the concentration versus the
                      range χ of the electrostatic repulsion normalized by the
                      average particle-particle distance. When χ→0, the
                      particles are too far away from each other to interact
                      electrostatically and K=6.55 as predicted by the theory of
                      Batchelor. As χ increases, K likewise increases up to a
                      maximum around χ=0.5 and then decreases again to a
                      concentration-dependent constant over the range χ=0.5−1,
                      while the particles transition from a disordered gas-like
                      distribution to a liquid-like state with a narrow
                      distribution of the interparticle spacing.},
