For example, barrier films, such as gas penetration films, such as gas separation films, such as CO₂ separation recovery and purification of clean energy hydrogen, a contact lens, and an artificial lung, organic electroluminescence, a solar cell, a flexible device, and a packaging material, are mentioned.

Our research group focuses on the development of new and useful methodologies of organic reactions based mainly on Lewis acid catalysis, and their application to synthesis of biologically and pharmacologically active molecules as well as optoelectronic materials.
Chemistry is Art!!
The motivation of our research is accordingly to develop artistically beautiful organic reactions.

Our research projects aim at synthesis of novel organic molecules that exhibit unique chemical and physical properties for production of innovative functional material.

As a theme which I am advancing now, I am conducting mechanism elucidation of the chemical reaction of "oil paint" which can be said to be the representation of a natural paint, and improvement of the paint adjustment technique based on it and the composition analysis of other products of nature.

In our laboratory, we synthesize various biologically active compounds and aroma chemicals produced by human, plnats and microorganisms. In addition, we also synthesize the artificial molecules having functions superior to natural products for medicines, agrochemicals, aroma chemicals.

Our Lab’s interest is focused on the coordination chemistry of ruthenium complexes with polypyridyl ligands. Our research utilizes a wide range of synthetic, spectroscopic, crystallographic, and theoretical techniques to reveal the structure and reactivity of (polypyridyl)ruthenium. Our goal is to find some use of our fundamental understandings, on formation and substitution reactions in ambient temperature and photochemical reactions, for its biological application and photo-energy utilization.

In order to cope with an energy problem, developing the material about the "artificial photosynthesis" which can provide next-generation chemical energy from sunlight. Furthermore, I have also challenged the subject how the latest functional materials of these next generation are compoundable in an environment-friendly process.

Although research requires knowledge, such as vacuum technology, high temperature technology, analytical skills, crystallography, and solidification study, the posture in which I experiment carefully more than it is important.

The research team Inorganic Crystal Chemistry at Meiji University focuses on the growth of inorganic crystals and their application to environmental and energy materials. Various minerals are generated in magma and hot water through chemical reactions, and there are animal beings who are be able to produce inorganic materials with complicated forms which human beings can not imitate easily. We will challenge the preparation of various new inorganic materials by learning the above manufacturing in the nature world.

Research of biomaterials such as artificial bone is making high-tech medicine a reality. Studies in our laboratory are involved in research on biomaterials derived from calcium-phosphate ceramics. The aims are to develop materials technology to support organ regeneration and to establish novel cancer treatments based on the use of biodegradable ceramics.

In the laboratory of biochemistry, we establish the new technologies for the medical application using genes, proteins and cells.
Our vision:
i) Create the "seeds of tissues" for regenerative medicine
ii) Develop the "functional materials" in the field of medicine, dentistry and cosmetics
We develop the researches based on the policy of "Contribution to the Medical treatments by Biotechnologies“.

Our laboratory studies characterizing natural and artificial radionuclides in the environment and radiation safety for environmental science. We analyze distribution and behavior of natural radionuclides such as lead, radium, uranium, and thorium in the atmosphere, water and the rocks, and develop simply analyzing methods for artificial radionuclides (134Cs, 137Cs and 90Sr). An analytical method for radionuclides in environmental samples using γ-ray spectrometry combined with solid phase extraction on several extraction disks has been developed. On the other hand, the procedure of safety education and training has been also proposed for safety handling of various X-ray equipments used for researches.
