Stability of a Nanometric Zirconia Colloidal Dispersion under Compression: Effect of Surface Complexation by Acetylacetone

Stability of Nanodispersions: A Model for Kinetics of Aggregation of Nanoparticles

“…[24] (or by Eq. [25], in the case of uniform particles), once the charge number of particles is known.…”

“…According to de Gennes (23), the reason for the instability of nanocolloidal systems might be in their low charge (surface charge density times surface area). In some cases stable systems of nanoparticles could be prepared (24,25) but no kinetic measurements were published.…”

Surface Complexation of Calcite by Carboxylates in Water

“…At higher concentration, the same species may capture other ions released from the solid and cause more of the solid to dissolve into the aqueous phase. Besides, surfaces that are covered with complexing ions may be unable to bind to each other; in this way the aggregation of the particles may be controlled (2). A classic example is the growth inhibition or prevention of scale formation of sparingly soluble minerals from aqueous solutions (3).…”

Precipitation−Redispersion of Cerium Oxide Nanoparticles with Poly(acrylic acid): Toward Stable Dispersions

“…There are several lowmolecular weight molecules that are able to deal efficiently with this issue. These molecules called dispersants, ligands or peptizers serve their role to modify the interactions between nanocolloids through adsorption on the surfaces [20][21][22][23]30,31].…”
