The Global warming gas, carbon dioxide, sequestration
into
the deep ocean has been examined to develop the
essential
key technologies and their applications to efficient
removal of other air pollutants. In addition, various
types
of ionic liquids showing the unique physical property
behavior have been studied on the purpose of applying
them
to greeen chemistry, medicine, and energy.
