Last Friday the last practice of SPP Project was held. Grad school students gave lectures on principles of photovoltaics to high school students. We will be very glad that this is a good opportunity for them to know a research in a university and to be interested in science and technology.

Yesterday, students of Johnan High School experienced experimental evaluations of photovoltaics. We are grad that they can feel an atmosphere of an university laboratory.

In the evening, our laboratory held a year-end dinner near the campus. We could have a nice time together having beers and hot dishes.

Autumnal colors of leaves are at their best. Our campus might be the best spot of autumn tints in surrounding areas.

We attended an annual conference of Kyushu Chapter, the Japan Society of Applied Physics (Kurokami Campus of Kumamoto University, December 22-23). Almost all students had oral presentations, and Yoshitake had a lecture in a seminar. The students could have worthwhile experiences in the presentations including the preparations and hearing presentation. To our happiness, Mr. Ohmagari (M2) and Mr. Hirakawa (M1) received presentation awards.

The 11th Cross Straits Symposium on Materials, Energy and Environmental Sciences among Pusan National University (PNU), Pohang University of Science and Technology (POSTECH) and our graduate school were held in PNU. From our group, Mr. Kawai(M2) and Mr. Sakai(M2) attended it. They enjoyed Korean delicious dishes in addition to the presentations.

Last evening we opened a welcome party for Mr. Promros, who came from Thailand, and Mr. Chen, who came from China, at Asahi Beer Garden located in Hakata. We could spend a joyful time drinking fresh beers.

Today, students of Johnan High School actually experienced an fabrication process of solar cells. Next time they will evaluate the photovoltaic properties of them．This practical training is a part of SPP Project.

Prof. K. Takarabe of Okayama University of Science gave seminars on semiconductor physics under high pressures for two days. In the last lecture, recent results on his C3N4 research including the back ground were introduced. We could learn a lot in his seminars.

Last week and this week, we visited SAGA-LS and made measurements of XRD, NEXAFS and XPS on boron- and nitrogen-doped ultrananocrystalline diamond/amoprphous carbon films and cubic AlN films. From this, we will take much time to analyze the data.

Two new students, Mr. Promros, who is a lecture of King Mongkut's Institute of Technology Ladkrabang in Thailand, entered a doctoral course, and Mr. Chen, who graduated from Chongqing University of Posts and Telecommunications (CQUPT) in China this year, entered our laboratory as a research student.

Yesterday a commencement ceremony was held. Dr. Shaban officially received Ph.D from Kyushu University. He is the first foreign student that received Ph. D from my laboratory. He actively progressed a research and wrote many papers (JJAP: 4，APL: 2) as a first author. Last evening our laboratory had a dry party and cerebrated him. He is going to go back to Egypt next week. So the party combined a farewell one. We remembered many things. All the things made us warm-hearted. In the near future, we will have an opportunity to meet again in Egypt, Japan or some international conference.

Yesterday a couple of iron silicide groups menbers, Mr. Sakai (M2), Mr. Kawai (M2), Mr. Izumi (M1), Mr. Hirakawa (M1), and Yoshitake went to to  Semiconductor Center located in Kitakyushu Science and Research Park to conduct an experiment. We are very glad to initiate the next-step research. Everything in the experiment is new for us!

Mr. Yoshida and Yoshitake attended International Conference on PROCESSING & MANUFACTURING OF ADVANCED MATERIALS -Processing, Fabrication, Properties, Applications-(August 25-29, 2009, MARITIM Hotel Berlin, Germany), and had oral and poster presentations. We could have valuable discussions, and enjoy the conference and Berlin.

Yesterday all members of an iron disilicide group visited Semiconductor Center located in Kitakyushu Science and Research Park to have a meeting on a research. We could received valuable advices from researchers belonging to the Center, and we had a prospect of our future researches. We will be willing to come in order to do experiments although it takes an hour and a half from our campus. We had a good feeling toward new, beautiful, and comfortable Hibikino campus.

Last Friday, a public hearing for Mr. Shaban's doctor theses was held, and he gave an excellent presentation on his doctoral course research carried out from 2006. After the hearing, our laboratory opened a tea party to show appreciation of his effort. Mr. Nomoto, who progresses the research in his master's course student together with Mr. Shaban and graduated last spring, came and celebrated Mr. Shaban. Mr. Nomoto introduced his fiancé to us.

Yesterday our laboratory held a barbeque party in our campus. Mr. Promros, who is going to enter a doctoral course  from October, and Mr. Nakagawa, who graduated from our laboratory last spring, additionally joined. We could have a nice time drinking, eating and talking!

12th Summer School of the Semiconducting Silicides and Related Materials Division of the Japan Society of Applied Physics was held at Daikanso, which is a long-established hotel in Chikushinoshi and is located near the campus, on August 1-2. From our lab, Mr. Hirakawa (M1), Izumi (M1), Kawai (M2), Sakai (M2), and Shaban (D3) attended. Prof. Miyoshi has a invited presentation, and Mr. Izumi, Kawai, and Shaban had poster presentations. 

Last Tuesday and Wednesday NEXAFS and XPS measurements were conducted for UNCD films in Saga--LS (BL12). From this Diamond group members will be very busy for the attendance at 20th European Conference on Diamond, Diamond-Like Materials, Carbon Nanotubes, and Nitrides, held in Athens on 6-10 of September.

We introduced our research on ultrananocrystalline diamond films in Fukuoka Nanotech Now 2009 held in Kitakyushu on June 11-13. Diamond-group members (4 persons) cooperatively prepared panels and exhibited there. Many engineers and researcher, whose number exceed that we expected, visited our booth. The students could have a lot of opportunities to talk and discuss with them, which became a valuable experience for the students.

On 9th and 10th of this month, we made X-ray diffraction measurement for ultrananocrystalline diamond films at BL15 of Saga-LS. The measurement could be completed owing to cooperation from center staffs．

Last evening, we went to Dazaifu Shrine to view Japanese irises. Fortunately it was the first day of lighting up yesterday and old-style restaurants were opened. We could enjoyed viewing the irises and had a relax time having dinners. On the way to the campus we dropped by some place in Dazaifu and enjoyed appreciating fireflies flying in the dark. We have never seen such a large number of fireflies. It might be because it was warm and humid last evening.

A softball game tournament was held by our department last Saturday. We have trained nearly every evening for this tournament, and graduates (Mr. Sakamoto and Mr. Nomoto) came along on the day. We are so sorry that we lost the quarterfinal match.

An open campus was held today. We introduced our researches and exhibited solar cell toys.

On May 2, all graduates of recent two years got together in the laboratory. We could freely talk the recent situations with each other. In the evening, the graduates took the students to a tavern near the campus and they spent a joyful time drinking beers.

Today an entrance ceremony was held at Chikushi Hall in our campus. One and five students enter doctor's and master's courses.
