A density functional theory evaluation of hydrophobic solvation: Ne, Ar and Kr in a 50-water cluster - Implications for the hydrophobic effect

► We show that internal pressure is largely responsible for hydrophobic solvation. ► Work is required to make a hole in a large water droplet. ► This work had not been accounted for in the interpretation usually used by biochemists. ► When included, it negates the need for an entropy argument.
