| Outline of Final Research Achievements |
We investigated the mechanism of kinetic hydrate inhibitors (KHIs) using molecular dynamics simulations. It is found that crystal growth of clathrate hydrates is not caused by direct interactions between KHIs and water molecules on the hydrate surface but by the Gibbs-Thomson effect. We compared adsorption of KHIs on clathrate hydrates with that of antifreeze proteins on ice Ih, and found that the former is more versatile and flexible than the latter. We also examined novel ice structures that are stable under high pressure and negative pressure.
