Mechanochemical technique aims to strike a balance between defect formation via ball milling and size adjustment of a solid grain to nanoscale (<1000 nm) (Ullah et al., 2014).During the process, a high-energy mill is employed and a specific powder charge is placed along with a milling medium (Lin et al., 2017).The kinetic energy generated during the motion of moving balls is applied to the ...

Commercial powders of pure magnesium were processed by high-energy ball milling. The microstructural and morphological evolution of the powders was studied using scanning electron microscopy (SEM), energy dispersive spectrometry (EDX) and X-ray diffraction (XRD). From the results obtained, it was determined that the ball size is the most influential milling parameter.

Moreover, in all syntheses, the use of ball-milling resulted in materials that were purified by centrifugation followed by dialysis (from 0.5 to 30 kDa) or by centrifuge filtration [33., 34., 35.]. The resulting CDs were reported as homogeneous and stable in solution for months without agglomeration or precipitation . These promising results ...
