Outline of Final Research Achievements

While developing methods for neutron diffraction experiments under high pressure, we have succeeded in elucidating the structure and properties of hydrous minerals that can exist in the Earth's interior, hydrogen in iron that makes up the Earth's core, and ice that makes up the ice planets. By elucidating the hydrogen position s, which cannot be resolved by other methods, this research has led to the discovery of a new polymorph of ice that have not been found before, the elucidation of the hydrogen-induced volume expansion rate of iron, which could limit the chemical composition of the Earth's core, and new issues such as the pressure response of hydrogen bonds, which could limit the deformation mechanisms of minerals that make up the Earth's interior. It is no exaggeration to say that we have established the discipline of hydrogen material science in earth and planetary science.

Academic Significance and Societal Importance of the Research Achievements

本研究で得られた研究成果の学術的意義はきわめて大きい。地表から最も遠い地球核の化学組成は鉄を主成分としており、何らかの軽元素が含まれることが古くから指摘されているが、具体的な化学組成は未解明である。本研究成果は地球核の化学組成に大きな制限を加えることになるだろう。また、新たな氷の多形の発見は、水という我々にとって最も身近な物質にもまだまだ解明されていない問題があると言うことを世の中に示すことができた。この研究成果は一般の方にも興味をもたれており、社会的な意義も大きい。
