Chemistry–Methods, Volume 5, Issue 11, November 2025.Mechanochemistry can be considered as the top‐down and bottom‐up synthetic methodology, but for the latter, there are some limitations, especially regarding particle size (nanometric species). It is presented that in specific precursors’ preparation and mild mechanosynthetic conditions, these limitations may be overstepped, which results in the ...
