Major achievements
Asami Sano has contributed unique research on elucidating the stability of hydrous minerals and the behavior of hydrogen in the crystal structure at high pressures by using X-ray and neutron diffraction techniques. For example, she succeeded in observing the theoretically predicted pressure-induced hydrogen-bond symmetrization in a hydrous mineral δ-AlOOH. She also clarified that δ-AlOOH is stable up to the pressure up to the core-mantle boundary showing that water transport associated with subducting oceanic plates extends throughout the lower mantle. Furthermore, using a combination of neutron and X-ray diffraction experiments, she has revealed for the first time the location of minor amounts of hydrogen in wadsleyite, a main constituent mineral of the mantle transition zone. In pursuing these studies, she also has been involved in developing the first high-temperature, high-pressure neutron diffractometer for the large-volume press in the world. She is recognized as a leading researcher in high-pressure neutron science in Japan and is a worthy recipient of the Nishida Prize.
