| Research Abstract |
Pressure- and temperature-induced structural change of liquid water from ice-like structure at ambient conditions to simple-liquid-like one has been revealed by synchrotron radiation x-ray diffraction and molecular dynamics simulation studies. Methods for neutron diffraction experiments under high pressure were developed and measurements on silica glass up to 9.9 GPa and water up to 0.8 GPa and 200 ℃ were carried out. X-ray diffraction studies on other liquids were also carried out.
