New Energy Science

 While energy is indispensable for the survival of the human race, fossil energy resources such as oil and coal are facing the greatest crisis of depletion. In response, the development of new and sustainable energy resources and effective use of energy have become essential. Given such conditions, fields such as electric energy, dynamic energy, heat energy, chemical energy and fusion energy are merged in this major and students will conduct education and research on the development and effective use of energy from various aspects. The students will also be engaged in educational research on the search for fundamental patterns of the existence of substances, space-time and energy; analysis of molecular energy such as laser spectrometry and radio spectrometry using high-sensitive and high-precision methods; condensed molecular materials chemistry such as high-functional catalytic chemistry, high polymer chemistry, coordination chemistry, dynamics of material exchange and energy harmony, hydrogen isotope science including tritium; basic science and material development of fusion; dynamics in terrestrial evolution and formation of subterranean resources, etc. from broad perspectives ranging from elementary particles to the universe.
