 “Connect our relationship!  Biodiversity: High School Students’ Challenge”
   On August 3rd and 4th, “Connect our relationship!  Biodiversity: High School Students’ Challenge” was held by Ehime Prefecture.  Two students, who are the members of the biology club, made a presentation, “Variety of butterflies in the local forest –theoretical value and actual value-”   They got the prefectural governor award (the highest award).  Members of the biology club go to Hojo Town and research butterflies there every month.  Their steady effort was awarded.   They would like to continue their research in the future.
   In the field work 20 students from 8 high schools including our school conducted the biological survey in the forest of Kazahaya area.  Students did their research after receiving the guidance from Mr. Matsui Hiromitsu, the representative of the nonprofit organization, “Mori kaea tsuzuku michi.”  They did the workshop titled “How to Preserve the Local Biodiversity.” 
   Our school student, Hanaoka Ryunosuke acted actively and announced the summary in the workshop.

   On the return day, I left the hotel at 5am and headed to the airport.  At first, there was a small problem when I left my luggage, but I managed to get on the plane.  However, even after 1 hour, the plane did not fly, and after a while, an announcement that “departure was delayed” flowed and was got off from the plane.  I thought I will miss the connecting flight, so I asked the staff, but it was a very cold reply.  I felt the greatness of the Japanese airline.
   After all, because of bad weather in Chicago, there was only one late flight that day, but I was not allowed to ride it.  However, it is a big trouble that only the baggage goes to Chicago due to the mistake of the airline.  I couldn't return to Japan on that day, and I stayed at Dr. Mani’s house that night.
   The next day, I left home early in the morning and headed for Chicago from Hartford.  I was able to get on the plane safely.  There was no check between the international and domestic flights at the Chicago airport connection, it was free to come and go, and there was no customs and no passport check.
    This time, I was able to leave Chicago and arrive safely in Japan without getting in trouble.  Thanks to Dr. Mani’s wife’s negotiating with the airport staff, I was able to pick up my baggage at Narita Airport.
    The first thing I felt when I came back to Japan is that it is delicious whatever I eat.  I thought I had a strange taste.  All American foods have high calories and the tastes are quite different from those in Japan.  I felt that I spent about 40 days in such a situation.
    Recalling that now, it seemed like a long time, but it was not true and s short time.  I am very grateful to all the people for their cooperation in various aspects including Dr. Mani.  I would also like to share my valuable experience with many people.

   About two weeks in Dr. Mani’s lab, I was able to conduct a series of experiments starting with the creation of molecules and measuring the emission and absorption.  I used NMR (Nuclear Magnetic Resonance) to confirm whether what we wanted to make was really made or not.  With the students in his lab, I did TLC (Thin Layer Chromatography) and Column Chromatography (Column Chromatography).  I also used a new laboratory instrument to remove the material in the flask.  The instrument was much more efficient than a micro spatula.
   On the last weekend, Mr. Sakurai took me to various places.  On weekends, there is a small market in each district.  So, I went to Peach Market.  Unlike the name, there was not much peach.  After that, I met the family and went to see the boat competition.  I went to a Thai restaurant for the last dinner.  The way of serving rice was very interesting and very delicious.

  I am doing my research under Dr. Mani, who is an assistant professor at the University of Connecticut.  I use various experimental instruments every day.  First, I made samples and measured absorption using spectrophotometer, and used a fluorometer to measure emission.  At first, I was puzzled about how to use these experimental instruments, but using it many times, I was able to do it well.
  Of course, it is more difficult to analyze the results than to conduct experiments, and we are conducting research with the guidance of Dr. Mani.  On weekends, I went to the shopping mall and the organic supermarket with him.  I ate a hamburger and French fries with cheese.  It felt American style.

This week, I visited the laboratory at the Department of Chemistry at the University of Connecticut, where Dr. Tomoyasu Mani, a first-year graduated student of SSH works.  I made the D-A (donor acceptor) molecule based on BODIPY (boron-dipyrromethene: a type of fluorescent dye) using the Suzuki Coupling method. I used Rotary evaporator and Column chromatography in this experiment, and I was surprised to find so many experimental instruments that I had never seen before.  But I was more surprised.  In the United States, it is thrown away when the test tube and the pipette etc. are used only once.  I thought it was unthinkable in Japan.
   I study for about six hours every day, but I feel that time passes very quickly, and I spend a fulfilling life.
Until last week, I was living in a university dormitory, but this week I'm living in a hotel in the university.  The hotel has a swimming pool, and of course all TV programs are in English, so it's also a good way to learn listening.  A lot of Japanese anime is broadcast in English.  I went to the supermarket.  There were many types for each food.
 *The Suzuki reaction is an organic reaction, classified as a cross-coupling reaction, where the coupling partners are a boronic acid and an organohalide catalyzed by palladium complex. It was awarded the Nobel Prize in Chemistry by Akira Suzuki in 2010.
