| Outline of Final Research Achievements |
Using molecular dynamics simulations and theoretical methods, we have studied the influence of confined space and solute on the phase behavior of water. We showed the potential solid-liquid critical point of water in carbon nanotube and the formation of ice between a pair of antifreeze proteins even at room temperature. Furthermore, we investigated the mutual relationship between the structural change of macromolecule and its hydration shell, and the promotion/depression of freezing of water by macromolecules.

| Academic Significance and Societal Importance of the Research Achievements |
本研究は、水の相転移に関する研究である。熱揺らぎによって自発的に秩序が形成・崩壊する仕組みの分子レベルの理解は、物理化学の重要な課題の一つである。また、水の相転移は、雲の形成や食品の保存など、我々の生活と強く結びついている。水の基本的性質の理解は、タンパク質の機能や溶媒効果を考慮した材料の開発など、多様な分野へ繋がる。
