“…However, the asymmetry between water-positive-ion and waternegative-ion interactions can lead to ion-sign preference in condensation of water. This phenomenon is known as the sign preference [6][7][8][9][10][11][12][13].…”

“…Examples include ion-induced nucleation [1][2][3][4][5][6][7][8][9][10] and nucleation in a uniform electric field. [11][12][13][14][15][16] The classical theory of nucleation predicts that the barrier height to nucleation is proportional to the cube of the surface tension in the absence of electric field.…”

In the framework of modified mean-field density-functional theory, effects of a uniform electric field on the interfacial properties of a model dipolar fluid ͓Teixeira and Telo da Gama, J. Phys.: Condens. Matter 3, 111 ͑1991͔͒ are studied. Both density and orientational order-parameter profiles of the planar vapor-liquid interface are obtained as a function of the field strength. For the dipolar fluids with reduced dipole moment 0 *р1, we find that the field ͑under the condition 0 *E*/T*Ӷ1͒ can shift the surface tension by few percent. We also find that the electric field actually reduces the thermodynamical surface tension but enhances the mechanical surface tension at the equimolar dividing surface. To detect these field effects on the surface tension we estimate the field strength which can be as high as 10 8 V/m.

“…[1][2][3][4][5][6] The phenomenon of ion-induced nucleation plays an important role in atmospheric condensation, particularly in the ionosphere. While both positive and negative ions increase the nucleation rate, a variety of substances exhibit a dependence of the nucleation rate on the sign of the ion.…”

Density functional theory is applied to ion-induced nucleation of dipolar molecules. The predicted reversible work shows a sign preference, resulting in a difference in the nucleation rate by a factor of 10-10 2 , for realistic values of model parameters. The sign effect is found to decrease systematically as the supersaturation is increased. The asymmetry of a molecule is shown to be directly responsible for the sign preference in ion-induced nucleation.
