|Outline of Final Research Achievements
What we have learned from this project is summarized as follows. First, the mean-field approximation of liquids is capable to reproduce the solvation free energy, μ, and the hydrophobic interaction, w(r), and one can understand mechanisms of the temperature T, pressure p, salt concentration c dependences of μ and w(r). Second, in each mode of T, p, and c variations, there exist linear correlations between μ and w(rc) with rc the contact distance between hydrophobic solute molecules. Third, the mean-field approximation is extended to inhomogeneous fluid systems and temperature dependences of local μ(z) are now understood based on the mean-field approximation. Fourth, a model hydrophobic polymer, which we devised, undergoes upon heating a coil-to-globule conformation change in water near room temperature. The mechanism of the hydrophobic collapse is clarified.
