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.
