Nanomaterials: a review of synthesis methods, properties, recent
Nanodiamonds can be synthesized using several methods, such as the ion irradiation of graphite, 221 high-energy ball milling, 222 carbide chlorination, 223 chemical vapor deposition, 224 and laser ablation. 225. Nanodiamonds possess a core–shell-like structure and display rich surface chemistry, and numerous functional groups are present on2.1. Ball Milling through the Mechanical Method. Ball milling is a mechanical method to fabricate nanomaterials. In this process, the materials are ground in a closed container. Small pebbles made of glass, ceramics, and stainless steel creates shear force during grinding. Bulk materials are subjected to place in the closed container.Nanomaterials: Synthesis and Applications in Theranostics

Ball milling as a mechanochemical technology for fabrication of
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).Interestingly ball milling process has also been applied as the pretreatment process for nanomaterial generation from industrial wastes. For instance, ball milling technique was employed for the synthesis of Zn NPs from waste tires collected from rubber industry (Moghaddasi et al., 2013).Synthesis of nanomaterials from various wastes and their new

Sustainable Preparation of Nanoporous Carbons via Dry Ball Milling
Disma et al. referred that the specific surface area of the ball−milling samples increased with the ball−milling time until a critical time was achieved, followed by a decrease. Following the same line of thought, Welham et al. [ 63 ] suggested that after the maximum surface area is reached, particles were rewelded, leading to a decrease in To promote the industrial applications of graphene, it is crucial to develop a low-cost, green, and efficient production method. A practical and eco-friendly deep eutectic solvent-assisted ball milling technique was developed to prepare multi-layer graphene in this study. The expanded graphite was used as raw material, and the deep eutectic Large-scale and green production of multi-layer graphene in
