Encapsulation of Silver Nanoparticles in a Polystyrene Matrix by Miniemulsion Polymerization and Its Antimicrobial Activity

Synthesis and Characterization of ‎Carboxymethyl Cellulose/Polystyrene ‎Core-Shell Nanoparticles by Miniemulsion ‎Polymerization

The first stage to have access to a reservoir is the drilling operation. The proper development of this operation plays a major role in increasing productivity. It must be pointed out that the drilling fluid (mud) is pivotal in achieving this objective. Among these fluids, water-based fluids are the most common ones, which have been utilized to drill approximately 80% of all wells and are m...

Synthesis of Silica/Polystyrene Nanocomposite Particles by Miniemulsion Polymerization

Miniemulsion polymerization is one of heterogeneous polymerization method that can be effectively used to synthesis of various novel organic-inorganic nanocomposite particles. This method can provide opportunity of good incorporation between the polymer and inorganic phases in the formed submicrometer-sized particles. In this article, we report preparation polystyrene/silica nanocomposite p...
