Challenges and opportunities in the bottom-up mechanochemical synthesis
The early focus in the field has been directed towards the preparation of metal alloys, metal oxides and sulfides, and the formation of composites. 48,51,61,65 Milling has also been employed as a top-down approach to prepare metal-based nanoparticles by hard stress and comminution. 61 More recently, the use of ball milling in the bottom-up synthesis of Milling was then performed in 80% ethanol for 30–120 minutes using a high-energy ball mill. The mechanical treatment resulted in a reduction of the fibre length and diameter, probably due to degradation of the cellulose amorphous regions. Fibrillation was helped by the wet environment, which facilitated the intra-fibre swelling.Ball milling: a green technology for the preparation and

Ball Milling an overview ScienceDirect Topics
Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134–141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].Summarily, synthesis of coconut shell nanoparticles through mechanical milling was achieved. The size of the CSNPs decreased with an increment in the milling duration. Formation of new phases such as C 2 MgO 6 is attributable to high surface energy of the CSNPs leading to chemical combination of the phases present in Synthesis of coconut shell nanoparticles via a top down
