In science:

While the brine and the vapor phases are semi-infinite, the pure-water layer is of thickness δ (to be identified with the hydration radius of an ion ), the first layer of adsorbed dense liquid alkane has a spatial extent of one molecular diameter σ = ∆z, and the film thickness of liquid alkane is denoted by l.

The most important of them concerns the cluster-cluster interactions, however, it is supported by the published distance distribution for these clusters joined by a flexible hinge.7 Notably, the contact distance is ≥40 ˚A, which corresponds to the diameter of a passivated cluster plus two layers of hydration water.
Comments on "Remeasuring the Double Helix"
With a dielectric electrode coating, the surface capacitance is relatively clear, but in the classical picture of the Stern model, it is associated with a hypothetical flat monolayer of water molecules, which limit the approach of hydrated ions at the metal/electrolyte interface.
Strongly nonlinear dynamics of electrolytes in large ac voltages
The PM thus neglects excluded volume effects of the latter, as well as hydration of ions and the expected reduction of the local dielectric constant near highly charged surfaces, due to polarization of nearby water molecules.
Effective interactions between electric double-layers
The polar water molecules tend to align with the local ionic field, creating a hydration shel l around the ion, lowering the response of the water molecules to the external field and hence lowering the dielectric constant.
