環境科学研究科を選んだ理由は?

 I became a student of the graduate school of environmental studies by destiny. My major was in material
chemistry at Peking university. I moved to Tohoku university because my present laboratory develops
hydrogen storage materials for use as a clean energy resource, which was really attractive to me. When I
became a member of the lab, which belonged to the Institute of Materials Research originally, I realized
that I would be a student of the graduate school of Environmental studies because my advising professor
teaching in this graduate school. It is definitely an honor to be student here, because the knowledge I have
learned from the graduate school, concerning the key concepts, methods of analysis and the achievements
in environmental issues, has always been enlightening me. It is also rewarding to know that my studies
may make a significant contribution to society.

現在どんな研究をしていますか?

 Together with my group members, I am now investigating on “hydrides” to be used as hydrogen storage
materials and electrodes in lithium ion batteries. In "hydrides", hydrogen atoms connect with other
elements by various types of bonding. When heated up to certain temperature, the bonds break and
hydrogen is released. The hydrogen density in hydrides is much higher than that in carbon fiber coated
steel hydrogen tanks. The study of hydrides as hydrogen storage materials is crucial for developing
hydrogen into a main clean and efficient energy resource. Hydrides containing lithium also have great
potential to be used in lithium ion batteries.

将来の夢や目標を教えてください。

 After finishing my doctoral degree, I would like to be employed at an institute or company aimed at
finding solutions for environmental issues by technological innovation. The deprivation of energy or
materials will ultimately lead to starvation, development imbalance and scarcity of natural resources.
Technological design of energy efficient new materials would definitely help solve many of the
environmental problems and aid the improvement of the living standards for human beings. I would like to
devote myself to these studies and ultimately make contributions to the society by ways of my research.

今後、環境科学研究科を目指す方にメッセージをお願いします。

 What impresses me the most about this graduate school is that there are plenty of chances for the
students to have conversations with experts from other fields. The whole education system, the outstanding
scientists involved in materials research and the astounding experimental facilities in the world renowned
Tohoku University really impress me. Besides, by listening to the professors who are working in
Environmental studies by way of economy, sociology and even archaeology, my horizon has been
broadened. The knowledge I have received from the graduate school helps me think outside of the box and
think systematically in my own studies. If you wish to devote yourselves to pursue solutions for
environmental issues as well as shape yourselves to be outstanding scientists, the graduate school of
environmental studies would never disappoint you.
