Structure and thermophysical properties of fullerene C-60 aqueous solutions

The structure and thermophysical properties of fullerene C-60 aqueous solut ions were investigated both experimentally and theoretically. The aggregati on kinetics results indicated that the structure of fullerene C-60 aggregat es in water could be described as a fractal system. The IR and electronic a bsorption spectra obtained confirm the presence of the crystalline phase in aqueous solution. The numerical values of thermodynamic coefficients alpha (P), beta (T), beta (S), c(P), and c(V), and sound velocity were determine d from the measured (P-V-T) data. The vibrational spectrum of the crystalli ne structure (Th symmetry group) formed from the hydrated single fullerene C-60 molecules in aqueous solutions was calculated using the molecular dyna mics approach.
