P5.10Wed 711:10-14:00Effects of the dielectric discontinuity on the counter iondistribution inside colloidal suspensionsAmin Bakhshandeh, 1 Alexandre P dos Santos, 1 and Yan Levin 11 Universidade Federal do Rio Grande do Sul, Av. Bento Goncalves, 9500, 15051,Porto Alegre, BrazilIn this work we introduce a new method for simulating colloidal suspensions with sphericalparticles. The method uses an exact calculation of the Green function, the ion-ion interactionpotential, in the presence of a dielectric discontinuity at the surface of a colloidal particle. The newmethod is orders of magnitude faster than the traditional approach based on a series expansion ofthe interaction potential[1] R. Messina, J. Chem. phys. 117, 11062(2002)10
