| Outline of Final Research Achievements |
Various thermodynamic anomalies exhibited by water have recently been considered to be ascribable to the existence of the second critical point at which two waters with different densities are not distinguishable. However, not only the critical point but also the two waters have never been observed. This study, which revealed the existence of the second critical point of tin tetraiodide using in situ synchrotron x-ray absorption measurements, is the world’s first identification. The existence of a region of density maximum in the liquid phase, which supports indirectly the existence of the critical point, was also disclosed.
