Influence of solvent granularity on the effective interaction between charged colloidal suspensions

E. Allahyarov, H. Loewen

Explicit hard-sphere solvent in electrolyte simulations attracts counterions to nano-colloid surfaces via depletion and can reverse long-range forces from repulsive to attractive for divalent ions.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

For divalent counterions and nano-sized colloids, hydration may lead to overscreened colloids with mutual attraction while the primitive model yields repulsive forces.

C2weakest assumption

That the hard-sphere solvent plus primitive-model ions sufficiently capture real hydration and that the observed force reduction survives when the solvent is coarse-grained into the SPM.

C3one line summary

Explicit solvent granularity renormalizes colloidal charges and induces hydration-driven attraction absent from the primitive model.
