Ball milling was combined with enzymatic pretreatment in order to decrease the energy consumption and to obtain high quality and homogeneity of the CNF. The process conditions, dispersity, morphology, degree of polymerization, and crystal structures of the resulting two kinds of CNF obtained were compared and discussed.
TiO2 photoalysis is been widely studied for air and water purifiion appliions; titanium dioxide is the most used semiconductor principally because its low cost, stability and chemical properties. However it only utilizes the UV portion of the solar spectrum as an energy source (less than 4% of the total sunlight energy). This behavior is due to its high band gap value of eV.

The comminution of the material to be ground takes place primarily through the highenergy impact of grinding balls in rotating grinding bowls. The grinding can be performed dry, in suspension or in inert gas. In addition to comminution, you can use Planetary Mills for mixing and homogenising of emulsions and pastes or for mechanical alloying and activation in materials research. HighTech ...
The milling was carried out at various milling speeds, namely 300, 660, and 900 rpm. Results suggested that the structure of the nanotubes is preserved with prolonged grinding of magnesium hydride and SWCNT in a ball mill for 180 min at a relatively low grinding speed of 300 rpm.

We report the first study of the effect of highenergy mechanical deformation on amorphous ironbased metallic alloys. The structural changes happening in amorphous ironbased materials containing Co or Ni during mechanical deformation show that the structural stability of an amorphous alloy against a thermal and a mechanical process are not related.
Material and milling bodies (usually balls) are loaded into the jars. The treated material particles undergo multiple collisions with the grinding media and the jar walls. The efficiency of planetary mills is the result of the high kinetic energy of grinding media. High velocity of moving milling bodies exerts high stress on the activated material.
