| Outline of Final Research Achievements |
We have developed an efficient evaluation method for hydrogen absorption properties on metal using quartz crystal microbalance. This method can be applied to the extreme condition such as low temperature and/or small amount of sample, to which the conventional volumetric method is hard to perform. In addition, we have revealed some interesting properties on hydrogen induced phenomena, especially on superconducting nature of PdHx system by performing in situ magnetization measurement down to 0.5 K.

| Academic Significance and Societal Importance of the Research Achievements |
水素社会の実現に向けては、もちろん我々が生活する室温領域で有効に動作する水素デバイスの開発が重要であることは間違いありません。しかしながら物性の本質を見ようとする場合、室温では温度が高すぎる場合あり、我々は特に低温における水素吸蔵特性の評価から本質を探ろうといスタンスで研究を進めています。高温では隠されている物性が材料開発の鍵を見出す可能性を本研究は秘めています。また、本研究で実施した極低温領域における金属水素化物の超伝導に関する研究は、人類の夢である室温超伝導実現に向けた知見を得る可能性を内包しており、学術的にも社会的に意義深い重要な研究課題であると考えられます。
