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 272.85-273.15K. 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.
