Another fundamental result on the origins and causes of mechanochemical reactions. Out now in Angew. Chem. Int. Ed.

When it comes to ball impacts, each and every one makes a difference.

Another collaboration with Francesco Delogu and his team at Uni Cagliari describing a set of unique experiments that aim to understand what is happening after a milling ball hits and compacts a powder that is prone to a chemical reaction.

Angew. Chem. Int. Ed. 2023, e202308046 (open access thanks to Uni Cagliari)

The image is showing mapping of the product at the site of ball impact.

Continuing on the previous study on the bulk transformation, we have now studied the mechanochemical transformation that is occurring in individual impacts. And yes: the overall bulk kinetics stems from the kinetics of individual impacts. Results are based on the purely mechanical trimerisation of a nickel complex, Ni(dbm)2, that can even be visually observed as the initial brown powder becomes green.

Congratulations are in order in particular to Maria Carta for performing a set of meticulous experiments.
