Mechanical Milling: a Top Down Approach for the Synthesis of
Zinc oxide nanoparticles were synthesized by K Vojisavljevic et al[121] by milling in a planetary ball mill with a zirconia milling assembly for up to 5 h in air. The deviation of the lattice parameters from single crystal values was related to defect creation and increase of strain inside the hexagonal lattice of milled ZnO nanoparticles.
