“…As an extension of the present work, we mention that in the presence of multivalent aqueous electrolytes or molecular solvent with structure, , polarization effects may be significant depending on the difference of the dielectric properties between the solvent and solutes. The impact of polarization effects in the renormalized charge of small nanoparticles in the presence of multivalent ions can be determined using a versatile numerical method developed recently in our group .…”

“…In particular, the random phase approximation (RPA) was used for the correlations describing the various components of the supporting electrolyte (small ions plus water molecules), whereas the HNC closure was still used for the correlations between a nanoparticle and the remaining components. 43,44 The correlation data was then used to compute renormalized effective charges of nanoparticles of 30 nm diameter with bare charges ranging from q M ¼ À1500 to q M ¼ 1500. In that work, a large asymmetry of the charge renormalization was shown to exist between the positive and negative particles.…”

“…The renormalized dielectric constant E (r) is mostly generated by the polarizability of the solvent, whereas the inverse screening length h includes this effect and the ionic strength of the solution. [42][43][44] In the limit of infinite dilution of small ions in the background, we have that E (r) becomes identical to the dielectric constant of the background solvent, 3 s (z 80 for water at room temperature and low ionic concentration).…”

“…On the other hand, to account for strong colloid-ion and colloid-colloid interactions requires a full non-linear theory. One approach that has proven to be very useful for describing the non-linear correlations between the colloidal particles and the counterions is the concept of charge renormalization 1,13,14 .…”
