Discrete solvent effects on the effective interaction between charged colloids

E. Allahyarov, H. L\"owen

Explicit hard-sphere solvent in simulations makes effective forces between charged colloids attractive for divalent counterions via hydration while only renormalizing charge for monovalent ones.

Claims

C1strongest claim

For divalent counterions, the total effective force can become attractive generated by counterion hydration, while for monovalent counterions the forces are repulsive and well-described by a solvent-induced colloidal charge renormalization.

C2weakest assumption

The hard-sphere solvent plus explicit counterions in a finite simulation box faithfully represent the hydration and many-body effects present in real aqueous electrolytes at the studied densities.

C3one line summary

Discrete solvent effects generate counterion-hydration attraction for divalent cases and charge renormalization for monovalent cases between charged colloids.
