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