“…and from these functions ln γ 2 (X 1 ) according to equation (26) we determined parameters of VD-AS model: (Λ 2 , Λ 3 , Λ 4 ) (see Table 2). Formally, the huge values of summary virial coefficients Λ i , in general, are not surprising, if we remember that, according to the physical sense, the last ones are the sums of the rows, consist of probably thousands terms, responsible for the energies of interactions of few nano-clusters with very large number of water molecules.…”

The temperature of water-ice crystallization initiation decreases (∆T) were determined in the binary water solutions of water soluble fullerenol: C 60 (OH) 24 − H 2 O at 272.85-273.15 K. Solution concentrations (in molar fractions) vary over a wide range x nano−cluster = 5.0 • 10 −6 ÷ 1.6 • 10 −4 a.un. Liquidus temperatures were determined with the help of Beckman thermometer with a linear resolution of the device scale ∆T ∆h ≈ 0.01 K/mm (h-height of Hg capillary raising). For the thermodynamic description of the discussed systems, we have elaborated an original semi-empirical model, the virial decomposition asymmetric model (VD-AS), with assistance from partial molar functions of nano-clusters (activities and activity coefficients) were calculated. The Gibbs energies for the solutions and miscibility gap concentration regions were calculated. VD-AS model excellently describes pre-delamination or micro-heterogeneous-structure formation in the considered solutions. These calculations are confirmed by the dynamic light scattering data.

Solubility diagram was investigated by the method of saturation in ampules at 25 ± 0.02 • C for 4 hours. The solubility diagram of the PrCl 3-C 60 (OH) 24-H 2 O ternary system at 25 • C occurs as simple eutonics, consisting of two branches, corresponding to the crystallization of crystalhydrates: PrCl 3 • 7H 2 O and C 60 (OH) 24 • 18H 2 O. The diagram contains one non-variant point each-eutonics, which corresponds to saturation with pair of crystal-hydrates simultaneously. The diagram also contains very short branch of PrCl 3 • 7H 2 O crystallization, and long branch of C 60 (OH) 24 • 18H 2 O, where the effect of fullerenol salt-out is distinctly observed.
