Ammonia-mediated Method for One-step and Surfactant-free Synthesis of Magnetite Nanoparticles

Magnetite (Fe3O4) nanoparticles have been successfully prepared by a novel one-step and surfactant-free approach utilizing ferrous ion, as a single iron source. In this manner, the reaction occurs between two aqueous solutions via the spontaneous transfer of ammonia gas from one to another in room temperature. No ferric source or oxidizing specie, oxidation controlling and capping agents are ne...

Model Predictive Control of Free Surfactant Concentration in Emulsion Polymerization

Abstract: In emulsion polymerization processes, the surfactant concentration plays an important role in the latex stability, reaction kinetics and particle size distribution (PSD). Controlling the free surfactant concentration in the aqueous phase ensures the stability of the latex and the control of the micellar nucleation rate. The PSD is determined by particle nucleation, growth and stabilit...

Synthesis of polystyrene-silica composite particles via one-step nanoparticle-stabilized emulsion polymerization.

Polystyrene-silica core-shell composite particles are prepared by one-step emulsion polymerization with a nonionic initiator VA-086, solely stabilized by silica nanoparticles. The silica nanoparticles are successfully incorporated as the shell, likely due to the fact that the nanoparticles are thermodynamically favorable to adsorb and remain at the liquid-liquid interfaces during the emulsion p...
