RELATION BETWEEN THE SOLUBILITY AND THE EFFECTIVE SOLUTE-SOLUTE INTERACTION FOR C-60 SOLUTIONS AND LYSOZYME SOLUTIONS - A COMPARISON USING THE STICKY HARD-SPHERE POTENTIAL

We present a study of the solute-solute interaction and solubility for C-60 in CS2 solution. We have evidenced and characterised, by a secon d virial coefficient A(2), an attractive C-60-C-60 interaction in CS2 by small-angle neutron scattering, We present results about the temper ature dependence of the C-60 solubility in CS2 obtained with a static light-scattering technique, We have compared the dependence of the sol ubility versus solute-solute interaction for C-60 in CS2 to that of ly sozyme in aqueous solutions, using the effective hard-sphere adhesive potential for the solute-solute interactions in both systems, This com parison between C-60, a simple model particle for short-range interact ions, and other much more complex molecules like proteins shows the an alogies between the two systems.
