SY-76 [Symposium of Division of Supercritical Fulids]
Latest Trends in Supercritical Fluid Utilization Technology

Organizers:

Tomai Takaaki (Tohoku Univ.), Ushiki Ikuo (Hiroshima Univ.), Matsuyama Kiyoshi (Fukuoka Inst. of Tech.), Hirogaki Kazumasa (Univ. of Fukui), Nakayasu Yuta (Tohoku Univ.), Orita Yasuhiko (Science Tokyo), Torii Shogo (Albion)

In this symposium, we will actively discuss the latest research results from a wide perspective, from the basics of physical properties of sub- and supercritical fluids, to the application of sub- and supercritical fluids to the environment, energy, materials, etc.. Prizes will be awarded for outstanding student presentations.
