Fascinating article with an out of box thinking approach to nitrosation reactions, including ample experimental data.
It appears that the susceptibility of amines with different structures to form nitrosamines can be explored by mechanochemical nitrosation, and this presents advantages compared to solution reactions.
I would not expect however that it can be related to the kinetics of nitrosation in solid phase drug products as easily as the liquid phase kinetic studies cited by @ccdw. This also makes me recall a FreeThink presentation of G. Scrivens: Free Webinar: Nitrosamines in Drug Products describing a study which is a closer simulation of solid phase nitrosation kinetics potentially happening in drug products.
I expect that pressure, temperature, concentration conditions, along with particle breakage encountered in mechanochemical reactions do not reflect the nitrosation conditions which may arise in solid phase drug products, even during extreme manufacturing conditions.
