The phrase "dynamics of interactions" is correct and usable in written English.
It refers to the patterns of behavior and communication between different parties in a given situation (e.g. between people, countries, or organizations). For example, you could say: "We need to understand the dynamics of interactions between our department and other departments in order to ensure we are all working towards common goals."
However, a complete understanding of the dynamics of interactions between plants and ENMs is not clear enough yet.
The dynamics of interactions between components can be observed in Figure 5 which demonstrates changes in the interaction energy between different components of the system with time.
Signalling interactions often occur in the presence of non-participating individuals (audiences); the effect of these individuals upon the dynamics of interactions has been called the audience effect.
By using a bilinear approximation to the dynamics of interactions among states, the parameters of the implicit causal model reduce to three sets.
Dewatering associated with mining below water table to achieve dry mining conditions may exert significant pressure on water balance in terms of lowering the water table and change in the dynamics of interactions between surface water and groundwater.
The shape and form of the outer edge of the heliosphere is likely affected by the fluid dynamics of interactions with the interstellar medium as well as solar magnetic fields prevailing to the south, e.g. it is bluntly shaped with the northern hemisphere extending 9 AU farther than the southern hemisphere.
This joint Ministry of Health/UNICEF study was planned as the third in a series of assessments of the dynamics of interaction among Community Support Group volunteers, the local women with whom they interact, and the health service staff who support and facilitate such interactions.
A relatively simple scenario for the dynamics of interaction between the generators of expiratory and inspiratory signals produces pseudo-random behaviour of the type observed.
