13 This study aims at developing in situ water treatment systems employing
recycled local materials for use in rivers and lakes . Waste ceramic materials
have been considered potentially useful as recycling materials for preparation
of porous carriers supporting microbial adhesion and growth. Effective
microorganisms, including aerobes and anaerobes, used in the purification of
water supplies are immobilized in the surface-modified porous ceramics by
immersing the ceramics into a seed culture broth. Design and synthesis methods
for porous ceramics carriers with enhanced microbial functions from recyclable
waste materials are investigated.

13 The conservation and improvement of the global environment is becoming an
extremely issue. R&D studies on separation and enrichment films of CO2
(the main contributing greenhouse gas to global warming) from high-temperature
exhaust gas are carried out using ceramics such as MgO,CaO,Al2O3,Sepiolite,
Dolomite,rare earth oxides etc. The development of long-life and highly
efficient catalysts to reduce the collected CO2 to useful synthetic gases
(e.g., CO and H2) is also being studied using the PSRA (Pulse Surface Reaction
Rate Analysis) method.

13 The purpose of this joint reearch is to establish an automatic monitoring
system for measuring the global environmental pollutants such as acid rain
components in east-Asia region. The main research activities to be performed
at the NIRIN, University of Tasmania(Australia), Texas Texh University(USA),
Chungbuk National University(Korea) are the development of acid rain
monitoring network system consisting of the ion chromatograph for monitoring
the acid rain components including sulfate, nitrate, chloride, bicarbonate
(alkalinity), sodium, ammonium, potassium, magnesium, and calcium ions in
rain and environmental waters and the meteorological analyzer with a satellite.

13 The aim of this study is to develop the bromine-free halon replacements which
have a comparative fire-extinguishing ability with that of Halons. Halons have
a bromine atom for imparting the good fire extinguishing ability in the
molecule, but their use was banned due to the reason for the destruction of
the ozone layer by the bromine. The key point of our work is the use of CF3
radical in place of a bromine atom as a function of fire-extinguishing
mechanism in halon replacements. This project consists of the molecular
design of new Halon replacemnts of which molecular structure can genarate
CF3 radical effectively on contace with fire and the evaluation as a
fire-extinguisher.

13 The objective of this study is to develop novel plant growth regulators(PGRs)
for increasing the tapioca production yield and for stimulating the growth of
important plants with high CO2 fixation ability. Fluorinated and chlorinated
plant growrh regulators have been synthesized. It is found in the joint
project with the Thai Tapioca Development Institute that both of the PGRs
stimulated remarkably the tuber growth of tapioca. The chlorinated and
fluorinated PGRs are useful for the preparation of saplings and the
stimulation of the growth of many plants which should play an important role
for the improvement of global environment.

13 Recently, pollution of valuable water due to daily waste water or industrial
waste water has been spreading on the earthwide scale to become a world wide
problem. The treatment of waste water using TiO2 photocatalyst is able to
decompose toxic and bioresistant organic pollutants readily. In such water
treatment studies, TiO2 powders in general have been utilized as
photocatalyst. TiO2 film photocatalysts have several advantages:
1)it is easy to treat,
2)filtration is not necessary to separate catalysts from treated water,
3)continuous treatment of waste water is possible. In this study,
the development of highly active TiO2 film photocatalysts prepared by sol-gel
method, the research on the destruction of bioresistant organic pollutants and
the development of water treatment system using the TiO2 film photocatalysts
are being performed.
