Micelle formation and the hydrophobic effect

Article Abstract:

A theory for micelle assembly that combines the account of the stoichiometric constraint with a description of the hydrophobic driving force is presented. The results reveals that the theoretical predictions for temperature dependence and surfactant chain length dependence of critical micelle concentrations for nonionic surfactants agree favorably with experiment.

A coarse-grained model of water confined in a hydrophobic tube

Article Abstract:

A lattice model of water confined in a hydrophobic nanotube is studied using analytical methods and computer simulation, where filled an empty tubes could degenerate in equilibrium. The analysis of transitions between the filled and the empty tube shows that density fluctuations at the entrances to the tube play the rate-determining role in the process.

Scaling of hydrophobic solvation free energies

Article Abstract:

The free energy of solvation for hard sphere solutes, as large as 20 Armstrong in diameter, in two simple-point-charge models of water, is calculated. The result suggests that the planar interface between coexistence, as measured by the difference in chemical potential between bulk liquid and vapor phases, and far from the critical point.
