Combining these methodologies overcomes the limitations of traditional solution-based or purely thermal approaches, enabling access to metastable or otherwise elusive polymorphs under milder and more sustainable conditions. Recent studies have shown that mechanochemical trans-formations proceed through distinct kinetic stages, including prolonged induction periods that can be tuned by adjusting the mechanical energy input[1]. These induction periods are associated with pro-cesses of mechanical activation, such as the accumulation of defects and increased surface energy, which lower the effective energy barriers for polymorphic transitions. Crucially, it is the total accumu-lated mechanical energy, rather than the duration or intensity of milling alone, that dictates the onset of polymorphic conversion, offering a new dimension of kinetic control[2-5]. Variable temperature ball milling reveals that the temperature required to induce polymorphic trans-formations can be significantly lower than under conventional thermal methods. For instance, tran-sitions that typically require high temperatures under equilibrium conditions can be achieved at sub-stantially lower temperatures in the presence of mechanical activation. This has been demonstrated in cocrystal systems such as nicotinamide-pimelic acid and isonicotinamide-glutaric acid, where the transition temperature was lowered by up to 25°C[2,3]. Real-time, in situ powder X-ray diffraction and temperature monitoring are essential for capturing transient phases and elucidating the interplay between thermal and mechanical effects. This confirms that combining mechanical energy with con-trolled temperature not only accelerates transformation kinetics, but also expands the accessible polymorphic landscape [2,3]. Collectively, these advances underscore the potential of real-time monitored, temperature-controlled mechanochemistry as a robust platform for the selective design and manufacturing of polymorphs. This approach provides unprecedented control over solid-state reactivity and opens new avenues for the sustainable and targeted engineering of functional materials and pharmaceuticals.

Various milling parameters, including milling frequency, time, filling degree of the milling jar, ball diameter, vessel size, degree of milling ball filling, and material of jars, are recognized influencers on the mechanisms and rates of product formation. Despite the growing interest in mechanochemistry, there exists a gap in understanding the mechanistic aspects of mechanochemical reactivity and selectivity. To address this, diverse analytical methods and their combinations, such as powder X-ray diffraction, X-ray absorption spectroscopy, NMR, Raman spectroscopy, and thermography, have been developed for real-time, in situ monitoring of mechanochemical transformations. This discussion centers on our recent findings, specifically investigating the formation of (polymorphic) cocrystals and metal-organic frameworks.

Notably, in the mechanochemical chlorination reaction of hydantoin, normalizing kinetic profiles to the volume of the milling ball unequivocally demonstrates the conservation of milling reaction kinetics. In this ball-milling transformation, physical kinetics outweigh chemical factors in determining reaction rates.
