Research Activities
Environmental Reaction Chemistry
We are conducting research on photochemical air pollution through volatile organic compounds (VOCs)-NOx-air system UV
irradiation experiments (smog chamber experiments) and computer simulations using chemical reaction models to estimate ozone
formation from various VOCs in the atmosphere (ref.1).
As a new toxic chemical species, gas-phase smoke radicals from combustion are studied. Gas-phase radicals were detected from
olefin-NOx-air system and the formation mechanism for gas-phase radicals from cigarette smoke was determined. In addition,
reactions of gas-phase smoke radicals with biological model compounds such as cysteamine are investigated to clarify toxicity
(ref.2).

Chemistry of Energetic Materials
Heats of formation for energetic materials such as nitro compounds were estimated by semi-empirical MO (molecular orbital)
method and molecular mechanics (ref.3).
Hazard evaluation program for heat release based on thermochemical calculation has been developed (ref.4).
Presently, modeling of thermal decomposition of energetic materials is being conducted by MO and chemical kinetic calculations
to investigate the relationship between chemical structure and thermal stability.

Messages to Students
I would like to make use of my research experience in atmospheric environmental chemistry, inorganic material chemistry and
safety chemistry to develop the field of environmental reaction chemistry.
I hope that you will learn much from the knowledge accumulated by predecessors and persevere in your research.
