“…The formation of new surfaces and interfaces, and the related processes that take place at the microscopic scale, enhance the chemical reactivity and concur to the initiation and progression of a mechanochemical transformation. [28][29][30][31] Within this framework impacts are crucial and yet, despite that their importance was recognized as early as in the 1970s, [32][33][34] the link between individual impacts and the overall transformation kinetics remained elusive. [35][36][37] Consequently, many fundamental questions of mechanochemical transformations remain open.…”

Mechanochemical Reactions from Individual Impacts to Global Transformation Kinetics

Typically induced by the mechanical processing of powders in ball mills, mechanochemical transformations are considered to result from the application of mechanical force to solid reactants. However, the undeniable deep connection between the dynamic compaction of powders during impacts and the overall transformation degree has yet to be disclosed. In the present work, we show that the square planar bis(dibenzoylmethanato)NiII coordination compound undergoes trimerization when its powder experiences even a single ball impact. Based on systematic experiments with individual ball impacts and analysis by Raman spectroscopy, we provide here quantitative mapping of the transformation in the powder compact and deduce bulk reaction kinetics from multiple individual impacts.
