Then the ion viscosity measured at 10 Hz drops by more than one decade, whereas only small ion
viscosity changes are observed at 1000 and 10,000 Hz.
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.
These cavities and holes may act as molecular sieves where large molecules or ions inter these channels and become locked there, while small ions
like Zn(II) are freely escaped.
Alumina crystals typically host small ions
like titanium or chromium, and neodymium ions are too large--they are normally hosted inside a crystal called yttrium aluminium garnet (YAG).
where t is the time, [mathematical expression not reproducible] are the mobility for small positive ions and large positive aerosol ions, respectively, [k.sub.nN] is the attachment coefficient of small ions
to aerosol particles, D is the diffusion coefficient, and E is the electric field.

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.
