Surface Chemistry of Nanometric Ceria Particles in Aqueous Dispersions

On the stability of aqueous dispersions containing conducting colloidal particles.

We use a combination of simulations and a simple theoretical approach to investigate interactions between neutral conducting surfaces, immersed in an electrolyte solution. The study is conducted at the primitive model level, which necessitates the use of multiple image reflections. Our approximate theory is based on a classical density functional formulation of Poisson-Boltzmann theory. The sam...

Click chemistry as a route to surface functionalization of polymer particles dispersed in aqueous media.

Proof-of-principle studies are described which show unequivocally that Huisgen click coupling can be performed successfully at the surface of polymer nano/submicron-size particles dispersed in aqueous media, thereby defining a generic strategy for attachment of a wide variety of functional molecules and providing a powerful, versatile route for the synthesis of surface functional particles.

Aqueous Polyalkyne Dispersions

INTRODUCTION The discovery of the conductive properties of conjugated organic polymers in the late 1970s initiated intense investigations of their synthesis, chemistry and physical properties. Today, they are widely studied for various applications, e.g. optoelectronics in displays or organic solar cells. Beyond general academic curiosity towards the generation and properties of unusual nanostr...

Aqueous Dispersions of Silica Stabilized with Oleic Acid Obtained by Green Chemistry

The present study describes for the first time the synthesis of silica nanoparticles starting from sodium silicate and oleic acid (OLA). The interactions between OLA and sodium silicate require an optimal OLA/OLANa molar ratio able to generate vesicles that can stabilize silica particles obtained by the sol-gel process of sodium silicate. The optimal molar ratio of OLA/OLANa can be ensured by a...
