Abstract
The temperature of water-ice crystallization initiation decreases (∆T) were determined in the binary water solutions of water soluble derivative of light fullerene C 70 with amino-acid lysine at 272.99 -273.15K. Partial molar excess functions for H 2 O were calculated.For the thermodynamic description of our systems, we have elaborated an original semi-empirical model VD-AS (Virial Decomposition Asymmetric Model), based on the virial decomposition of the molar Gibbs energy of the component molar fractions in the solution.With the help of the VD-AS model, partial molar functions of nano-clusters were calculated.Excess and full average Gibbs energies for the solutions and miscibility gaps concentration regions (with the help of diffusional instability equations) were calculated.Thus, the VD-AS model excellently describes pre-delamination or micro-heterogeneous-structure formation in the considered solutions.These calculations were accordingly confirmed by dynamic light scattering data.
