The 55th Symposium on Powder Technology

2024 Volume 41 Pages 280-281


The 55th Symposium on Powder Technology organized by the Hosokawa Powder Technology Foundation took place at the Hotel Tokyo Garden Palace in Japan on Monday, September 4, 2023. This event was held by the planning of the Council of Powder Technology, Japan and with the sponsorship of Hosokawa Micron Corporation. The theme of the symposium this year was “Powder Technology Contributing to a Sustainable Society”. There were seven lectures, including three KONA Award commemorative lectures, from basic and applied perspectives. This year’s symposium was held in a hybrid style, allowing both on-site and online participation.

At the beginning, Mr. Yoshio Hosokawa, the president of the Foundation, delivered the opening address mentioning that this symposium has been held almost annually in Osaka or Tokyo since 1968. However, due to the coronavirus pandemic, it was canceled for two years. Last year, a special event was held to commemorate the 30th anniversary of the foundation’s establishment in Osaka, and consequently, this event in Tokyo was for the first time in five years.

Prior to the lectures, the KONA Award presentation ceremony was held, and the plaques of the KONA Award were handed from the president to the two 2022 KONA Awardees; namely, Professor Hidehiro Kamiya, Director and Vice President of Tokyo University of Agriculture and Technology, and Professor Toshitsugu Tanaka of Osaka University. The contents of the symposium are shown below.

In the morning session, Prof. Kamiya and Prof. Tanaka gave the KONA Award 2022 commemorative lectures, in which they introduced their research results on particle adhesion and aggregation behavior in relation with the characterization and control, as well as on the development of discrete particle modeling and simulations of gas–solid two-phase flows, respectively.

The afternoon session began with the commemorative lecture for the KONA Award 2021 by Prof. Shuji Matsusaka of Kyoto University on advanced characterization of fine particles and the development of novel powder handling systems. Then, Prof. Toru Wakihara of the University of Tokyo and Prof. Tohru Sekino of Osaka University discussed a new preparation method for zeolite nanoparticles and its application, along with the creation of photo-physical-chemical functions by controlling the structure of the oxide nanoparticles, respectively, focusing on specific powder materials.

In the final session, Mr. Daisuke Ito of Murata Manufacturing Co., Ltd. and Dr. Aiko Sasai of Hosokawa Micron Corporation talked about the applications of powder technology and nanoparticle processing technology to the development of noteworthy products such as next-generation batteries, and regenerative medicine/cosmetics, respectively. After the end of the lectures, Prof. Hiroyuki Kage, Chairman of the Council of Powder Technology, Japan, gave the closing address, and the symposium concluded successfully.

Subsequently, in the reception hall, a social gathering was held for the first time in four years, allowing the lecturers and attendees to engage in meaningful exchanges in a relaxed atmosphere from beginning to end. The number of participants at this year’s venue was over 100, with nearly 240 in total, including online attendees. The following 56th Symposium is scheduled to be held in Osaka next year.
