Ball milling is a simple, fast, cost-effective green technology with enormous potential. One of the most interesting applications of this technology in the field of cellulose is the preparation and …
It is noted that the ball milling also enhanced the adsorption ability of biochars for other organic contaminants (e.g., tetracycline and reactive red) and heavy metals (e.g., Pb and Ni) ( Table 3).
The ball milling is a powerful method to break the nanoparticle aggregate, and has a better breakage performance than the mechanical mixing and the ultrasonication. With just a few minutes of the milling, the nanoparticle aggregates of a few tens of microns can be quickly broken to less than one micron, which is only one-tenth of those reached ...

The ball-milling contributed to a decrease in the particle size of SWCNTs and Si particles and to an increase in the electrical contact between SWCNTs and Si particles in the SWCNT/Si composites. 3.8. Some Other Nanomaterials and Nano Composites Lee et al[104] studied the Phase evolution of Fe 2 O 3 nanoparticle during high energy ball milling.
Alshora et al. prepared pioglitazone HCl (PGZ) nanoparticles via planetary ball milling [65]. They used the Box-Behnken factorial design approach to optimize the number of milling cycles, and the amount of stearic and electrostatic stabilizers. The optimized PGZ nanoparticle formulation enabled the dissolution to reach 100 % in 5 mins.
Mechanical ball milling, as a novel method to prepare nanoparticles with large-scale production, has been introduced lately. Sapcharoenkun et al.
