small ion

small ion

[′smȯl ′ī‚än]
(meteorology)
An atmospheric ion of the type that has the greatest mobility; and hence, collectively, it is the principal agent of atmospheric conduction; evidence indicates that each ion is a singly charged atmospheric molecule (or, rarely, an atom) about which a few other neutral molecules are held by the electrical attraction of the central ionized molecule; estimates of the number of satellite molecules range as high as 12. Also known as fast ion; light ion.

Ionic flow driven by pedot electrodes can, In contrast to metals, Be reversed with any small ion present in the electrolyte.
As it is a small ion with high mobility when under an electrical field, it is more efficiently extracted than the above-mentioned organic drugs.
It is claimed that the small ion size and charge associated with the silver ions in Axen, coupled with the stabilizing effect of the organic acid, allows the ionic silver to stay in solution without precipitating, thus preserving its efficacy.
The resulting detailed design concept for small ion pairs in solution will revolutionize not only ion-pairing catalysis but all scientific fields working with organic ion pairs in solution.
So the smaller size is attributed to the small ions replacement during the synthesis.

Small ions adapt to this situation by passive diffusion aiming at a balanced situation in which products of paired ions' concentrations (one anion and one cation) are equal on both membrane sides, under the condition that further water movement is prevented by the fixed volume of neighboring fluid departments.
However, it is desirable to have a general screening method for anions to reduce the number of tests required for unknowns and to detect small ions that are difficult to distinguish in a complex matrix.
These nonselective channels allow the movement of small ions as well as large molecules.
report that peptide nanotubes can act as channels, allowing small ions and molecules to pass from one side of a membrane to the other.
