Highly Heterogeneous Polarization and Solvation of Gold Nanoparticles in Aqueous Electrolytes
TL;DR: In this paper, the authors demonstrate significant effects of explicit metal polarizability on the solvation and electrostatic properties of bare gold NPs in aqueous electrolyte solutions of sodium salts of various anions (Cl$^-$, BF$_4$$$-$, PF$_6$$$)-nip$^)-nips, and 3-and 4-valent hexacyanoferrate (HCF)), using classical molecular dynamics simulations with a polarizable core-shell model of the gold atoms.

Controlled nucleation for the regulation of the particle size in monodisperse gold suspensions
TL;DR: In this article, a series of monodisperse suspensions of the same chemical composition but of rather different particle sizes was used to study particle size dependent phenomena, such as Brownian motion, light scattering, sedimentation and electrophoresis of small particles.
