Special Scientific Report #97-13 (May 12, 1997)

**US-Japan Workshop:**

**Nanoparticle Synthesis and Applications**

The following report was submitted by ***Dr. James R. Brock***,
Professor of Chemical Engineering, University of Texas, Austin, TX
78712-1062. ***Dr. Brock***, in conjunction with, with Professor Hiroshi
Komiyama, Department of Chemical Systems Engineering, University of
Tokyo, Tokyo, Japan, helped organize a U.S.-Japan workshop to discuss
topics relating to nanoparticle synthesis and applications. The workshop
was held Oct. 28-Nov.1, 1996 in Tsukuba, Japan. The workshop was jointly
sponsored by NSF and the Japan Society for the Promotion of Science
(JSPS). This project is one of the joint projects supported under the
U.S.-Japan Cooperative Science Program. ***Dr. Brock*** can be reached

**WORKSHOP REPORT:**

A Workshop was held in Tsukuba, Japan, Oct. 28-Nov.1, 1996 on
nanoparticle synthesis and applications. Approximately twenty
participants from the U.S. presented papers; these participants were
young doctoral or postdoctoral students from a similar number of
university research groups prominent in nanoparticle research; also,
there were participants from various governmental and national research
laboratories. On the Japanese side, there were approximately 21
participants from major Japanese universities and national laboratories
that presented papers. Of particular interest was a presentation by Dr.
Chikara Hayashi, Chairman of Vacuum Metallurgical Co., Ltd. who on the
first day gave an outstanding Plenary lecture on Ultrafine particles.

The Workshop began at 9 a.m. for presentation of papers with a lunch
break from 1200- 1300 hours. Every afternoon, from 1430 to 1730, lab
tours were arranged at the nearby National Institutes, as well as at NEC
Tsukuba Research Laboratory. Without exception our Japanese hosts during
these tours carefully explained theory and experimental procedures
dealing with nanoparticle synthesis and applications. The last day,
there was a lab tour at Tokyo University. Dr. Nabuhiro Aya, Mechanical
Engineering Laboratory, AIST-MITI, Japan generously gave of his time to
arrange for these lab tours, that in the opinion of many of the U.S.
participants were outstanding features of the Workshop. Particular
thanks and recognition are due the General Chairperson, Professor
Hiroshi Komiyama, Department of Chemical Systems Engineering, The
University of Tokyo and the local organizing Committee: Dr. Nabuhiro
Aya, Professor Kikuo Okuyama, co-chair, Hiroshima University, Prof.
Manabu Shimada,co-chair, Hiroshima University, and Dr. Kazuo Takeuchi,
RIKEN, Japan; many others also contributed to the evident success of
this Workshop.

It has been agreed to by the Editor of the Journal of Aerosol Science
(JAS) that all submitted Workshop papers will be considered for
publication in JAS. After a decision on acceptance, following normal
peer review, the papers will appear in a special issue of JAS devoted
entirely to nanoparticle synthesis and applications. Therefore, the
Workshop and its papers will be of record as an important milestone in
the development of nanoparticle science and technology.
