An Investigation on Milling Method in Reduction of Magnesium Nano-Powder Particles Based on Sustaining Chemical Activity

Magnesium has been used in aviation industries, automobile manufacturing, electronics and medical engineering due to its unique properties thus far. The main problem in its utilization is the high reactivity of magnesium with oxygen and humidity, which both changes its properties. The surface charge and different density results in difficulties in dispersion stability of the powder in an ...

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...
