A phase transition in H2O due to electrostriction pressure

Review: Water at ions, biomolecules and charged surfaces

“…ice VII (marked by 2, at 2 GPa) transitions under pressures applied in no field (E ¼ 0). They are far from the discontinuity in ¼ (Å t ) characteristic of the phase transition found in [16,44]. Hence, the discontinuous phase transition described above is not an artifact resulting from the use of the input data.…”

“…(2)) allowing calculation of some parameters of the system from the values of other parameters is the equation of state. In [16,44] it is shown that the same equation that relates electric quantities to the mechanical ones implies the existence of a phase transition: normal water ! compressed H 2 O.…”

“…We shall present a theoretical evidence that H 2 O at ambient conditions in a field of a strength taking the values from the range 0.77<E<1.36 (10 9 V m À1 ) (cf. Table I) undergoes a phase transition to a dense and orientationally ordered phase of H 2 O at a transition value Å t ¼ 0.2 GPa of the local electrostriction pressure [16]. The transition is accompanied by a latent heat as well as discontinuities in entropy and electric field.…”

“…Along the lines of our approach, for instance, a solution can be suggested of the problem of anomalous hydration of the Sr 2þ ion [16,54]. The steep variations (Fig.…”

“…However, in some liquids, the experimental value of NDE increment is positive. This 'abnormal' NDE increment is a consequence of an influence of a strong external field on molecular association [5][6][7], tautomeric equilibriums [8,9] as well as thermodynamic and critical fluctuations [4,10]. In the vicinity of the critical mixing point very strong increase in the NDE increment is observed [11][12][13][14].…”
