Research
Hydrophobic interactions play a central role in many chemical, biological and
technological processes. The hydrophobic effect is related to the disruption of
the hydrogen bond network in water. Details of the water structure around
hydrophobic solute depend on the size of the hydrophobic species. Although the
nature of hydrophobic forces is well understood, little is known about the kinetics
of hydrophobic interactions. Recently, atomic force microscopy has been used
to analyze the strength of hydrophobic interactions between hexadecane and
fullerene molecules. I use all-atom moleculal dynamics simulations and theoretical
models to describe the formation and rupture of the "hydrophobic bonds"
