Fundamental measure theory of hydrated hydrocarbons

To calculate the solvation of hydrophobic solutes, we have developed a method based on the fundamental measure treatment of density functional theory. This method allows us to carry out calculations of density profiles and the solvation energy for various hydrophobic molecules with high accuracy. We have applied the method to the hydration of various hydrocarbons (linear, branched and cyclic). The calculations of the entropic and enthalpic parts are also carried out. We have examined the question of the temperature dependence of the entropy convergence. Finally, we have calculated the mean force potential between two large hydrophobic nanoparticles immersed in water.
