"secondary reduction" is a correct and usable term in written English.
You can use it to refer to the further reduction of something that has already been reduced. For example: "The government implemented a secondary reduction in emissions targets in order to meet their sustainability goals."
It is worth observing that there is no secondary reduction process as the Ag+ ion requires only one electron (Ag+ + e- → Ag) for reduction to metal.
The secondary reduction will mean capturing one more electron by silver atom to become Ag- which is impossible because it cannot hold an extra electron into its orbit.
Any nanoparticle formation involves the following: (a) nucleation, (b) crystal growth of the particle, and (c) secondary reduction on the surface to stop crystal growth.
A good initial reduction is important no matter what type of fixator is applied, as it is often surprisingly difficult to achieve a secondary reduction if the primary reduction is unsuccessful.
Song and Kim [21] have hypothesized that with increasing temperature the rate of reduction of Ag+ ion to Ag also increases, stopping the secondary reduction process on the surface.
Whereas, at high temperature, due to a rapid rate of reaction, the primary nucleation is immediately followed by a secondary reduction on the primary nuclei; hence, particle growth is stalled.
This fluid movement can produce either systemic hypotension with secondary reductions in organ perfusion or direct organ injury if tissue edema interferes with oxygen and nutrient uptake [23 27].
However, as explored below, the secondary reductions of the lumbar region may be independent, parallel convergent adaptations to the various non-upright, "diagonograde" postures employed by the large apes.
This idea is completely corroborated with numerous data that the last common ancestor of Deuterostomia, Ecdysozoa and Spiralia had a segmented and coelomate body organization and that morphologically more simply organized taxa evolved by secondary reductions [ 74– 74].
Secondary reductions in consumption may occur from the negative publicity surrounding sugar sweetened drinks, resulting from either the continuing debate about legislation or the stigma attached to public awareness of a special tax on health grounds.
For example, the ancestral states of the maximal reported organism size and genome size (supplementary files 2 and 3, Supplementary Material online) suggest secondary reductions along the lineages leading to the different unicellular algae under study here.
