Test 1: We have performed in situ measures of effective forces in typical colloidal configurations, from the solution of a multi-center Poisson-Boltzmann theory (with Nc = 4000 colloids).
Testing the relevance of effective interaction potentials between highly charged colloids in suspension
Deriving now Zeff by comparing the solution of the PB equation with the known far-field expression for the electrostatic potential φ(r), one can again compute a colloidal background charge Zback which differs from the previous one.
