The objective of the Laboratory is the creation and evaluation of inorganic materials made from innovative processes that have a low environmental impact. Thus our work is related to both fundamental and applied research. In particular, the Laboratory specializes in the development of nano-structured materials. Specifically, the Laboratory carries out research into mechanochemical processes, combustion synthesis, induction field-activated synthesis, spark plasma sintering, and other new types of processing. In addition, the Laboratory is actively applying for and obtaining domestic and international patents related to the development of new materials.

In April 2006, the Ministry of Education, Culture, Sports, Science and Technology (MEXT) launched the High-Tech Research Center Project (HRC). Shortly thereafter, the Innovative Materials and Processes Research Center (IMPRCenter) was established for a term of five years to focus on the development of innovative materials for the effective use of energy.
The IMPRCenter is operated by the Department of Materials Chemistry in cooperation with the Department of Mechanical and Systems Engineering and the Department of Electronics and Informatics. The Center has 16 professors, two postdoctoral fellows, and two research assistants. -

With a focus on developing new materials based on innovative processes, this Laboratory encourages the participation of young, energetic students who have an interest in our fields of research.
Thus we enthusiastically welcome all of whom would like to do research from the viewpoints of theory and experimentation.
In addition, the Laboratory extends a special invitation to students who are looking ahead to graduate school. A year of lab experience would be very beneficial in immersing you in the world of chemistry and inorganic materials, and in teaching you the responsibilities of research.
