In the mechanical exfoliation process two types of normal force used to peel of the graphite and shear force utilize ball milling process [9,22,23,24,25]. The liquid phase exfoliation (LPE) method includes three basic processes, those are dispersion of graphite in suitable solvent, exfoliation, and purifying where van der Waals forces break down by solvents and ultrasound.

Connecting defects and amorphization in UiO-66 and MIL-140

Ball milling 50 mg of each sample was placed in a 10 mL stainless steel jar along with one 9 mm diameter stainless steel ball. The material was then ball-milled for the specified time in a Retsch MM400 grinder mill operating at 20 Hz. Computational details
