Abstract
The present work focuses on the challenges that emerge inconnection with the kinetics of mechanically activated transformations. This isan important topics to comprehend to enable the full exploitation ofmechanical processing in a broad spectrum of areas related to chemistry andmaterials science and engineering. Emerging challenges involve a number offacets regarding materials and material properties, working principles of ballmills and milling conditions, and local changes occurring in series in processedmaterials. Within this context, it is highly desirable to relate the nature andrate of observed mechanochemical transformations to individual collisions andthen to the processes induced by mechanical stresses on the molecular scale.Hence, it is necessary to characterize the milling regimes that can establish inball mills regarding frequency and energy of collisions, map the relationshipbetween milling dynamics and transformation kinetics, and obtain mechanisticinformation through proper time-resolved investigations in situ. A few specific hints are provided in this respect.
