@Report on the presentation at the Gordon research
conference on gOscillation and dynamic instability in chemical systemsh
and a visit to a research group in MIT.
Bates Collage, Lewiston, Maine & Massachusetts Institute of Technology
(MIT), Cambridge, Massachusetts, USA
Outline of the trip
i) Purpose of the trip
I made a trip to present a poster at the conference on chemical oscillation
and discuss with many researchers who were in the forefront of this field.
I also visited to a research group in MIT studying time-resolved spectroscopy
to discuss how we investigate the dynamic instability in chemical oscillations
in combination with laser spectroscopic techniques.
The Gordon research conference on gOscillation and dynamic instability
in chemical systemsh was held during July 18-23 in Bates collage, located
at the northeast end of the USA. This conference addressed Nonlinear
Chemical Dynamics, which included the study of oscillations, waves,
patterns and chaos in chemically-reacting systems far from equilibrium,
with experiments, theory and simulations. About one hundred participants
from all parts of the worlds presented exciting studies and discussed
animatedly with each other. I presented a poster about a coupled oscillator
in Belousov-Zhabotinsky (BZ) reaction, one of the typical chemical
Recently, chemical oscillation has been applied to many systems, such
as polymeric gels for micro/nano machine, computing with chemical waves,@stripe
pattern formation on the animal skin, coupling of two or many oscillators
and so on. Especially, polymer gels in chemical oscillation have been
extensively studied for industrial application in the future. Therefore,
there were many reports about gel systems at the conference. On the other
hands, several participants in the conference also studied coupled oscillators
in chemical systems, which had a close relation to my experiments. I.
Z. Kiss and Y. Zhai reported about synchronization and cooperative action
of coherent groups in globally coupled electrochemical oscillators. H.
Fukuda has arranged BZ beads-oscillators in 2D lattice and observed synchronization
enhanced under optimal noise, which impressed me above all presentations.
Many people paid attention to my poster presentation. Although I felt
the difficulty of speaking in English, it seemed that they understood
what I said. We discussed and exchanged ideas with each other. I was
glad to present a poster at the conference, in which many famous researchers
participated and moreover, appreciated my results. That was why I felt
After the conference, I visited he Nelson group in MIT and presented
my experimental results. They studied dynamic properties in complex materials,
such as glass, with time-resolved spectroscopic techniques which could
also be used for chemical systems. Unfortunately most of the members
were in Japan to attend the conference on Ultrafast phenomena at Niigata.
However, we discussed productively for methods in measuring complex systems
with laser techniques.
iii) Benefit from the trip
The trip to USA was valuable experience for me, especially from the following
(i) I learned recent trends in coupled oscillation through the talk with several
researchers involved in the fields.
(ii) In MIT, I was suggested that interferometer imaging may practical in measuring
dynamic instability in chemical systems.
iv) Prospective and future plans
I will continue to investigate dynamic instability in chemical oscillation
as the suggestion of the MIT group.
Finally, I express my gratitude to the COE financial support for the
