Abstract: | Summary The behaviour of electric dipoles (water molecules) under the action of a high and nonuniform electric field is investigated.
The model incorporates all the features of Clausius-Mossotti’s Debye’s, Onsager’s and Kirkwood’s approaches, and assumes,
as a novel feature, that the dielectrophoretic drift of dipoles is balanced by dipole diffusion. A new relationship among
local permittivity, electric field and water density is found that could explain why water molecules are rejected by charged
molecular crevices which can engineer the binding of ionized ligands at very high rates as compared to bulk water.
To speed up publication, the authors of this paper have agreed to not receive the proofs for correction. |
