Kazuma GOTOH, Ph.D. (Science)
Associate Professor

Research field:
Physical Chemistry, Inorganic Chemistry,
Nuclear Magnetic Resonance

Research Interests:
Current research topics are the structure, state and dynamics of molecules and ions doped in pores of nanoporous materials or materials intercalated between graphite layers. Research using solid state nuclear magnetic resonance can greatly contribute to the development of secondary batteries such as lithium ion batteries. Some novel nanocarbon materials and catalytic reactions are also developed.
