Outline of Final Research Achievements

Single beam type phonon resonance spectroscopy was developed. We have found that ice surface has an ability to induce ion exchange reaction with gallium(III) complex. As an unique phenomena of micrometer-sized freeze concentrated solutions, we examined the observation of the collosion process of iron contacting with freeze concentrated solutions. We found that the collosion behavior is regulated by the size of the freeze concentrated solutions .

Academic Significance and Societal Importance of the Research Achievements

氷は身近な物質であるにも関わらず、その物理化学的現象やそれが環境中での化学反応で果たす役割は未解明な点が多い。本研究内容は、マイクロサイズの凍結濃縮溶液がどのように反応に影響を及ぼすのか、またどのような反応場を提供するのかを明らかにするための一助になると考えている。
