目的および内容

申請者らのグループは、2016 年度よりプラズマとウルトラファインバブルを融合した合計6回の国際研究集会を開催しており、中国およびタイ王国の連携研究を強めてきた。2023 年度においては岩手大学が国際シンポジウムを主催している（ISPFB, The International Symposium on Plasma & Fine Bubbles, ISPFB, 5/17-20, 2023）。
　継続申請するプラズマ・ウルトラファインバブル研究会については、静電気学会の各支部と連携して、分野横断型の研究会として開催してきている。2024 年度は室蘭工業大学において開催し、同時開催した国際会議（The 8th Japan-Taiwan Workshop on Plasma Leading Science and Technology (8th JTPL 2024)）にも参加した台湾の研究者と様々な議論を行う事ができた。2025 年度での開催では、今のところ岩手大学において研究会開催を計画している。2027 年5 月に開催予定のISPFB(International Symposium for Plasma and Fine Bubble),岩手大学にて開催)に向けた関連研究者間でのディスカッションも開催予定であり、静電気学会の各支部の協力のもとに、オンライン併催も行いつつ国内外の研究者を集め、異分野融合としてのシンポジウム開催を行いたい。

15:50-16:05 Research Presentation (1)
Prof. Seiji Kanazawa (Oita Univ.)
“Electrostatics — An Old Yet Ever-Evolving Field”
Electrostatics is often described as an old yet ever-evolving field of study. It is closely linked to electrical discharge phenomena, which in turn lead to plasma generation. This lecture will present an overview of modern electrostatic applications, framed by a historical perspective on electrical discharge and its development. It will also highlight key future challenges in the field. Furthermore, the current state of electrostatics research in Japan’s Kyushu region will be introduced, with particular emphasis on the relationship between electrostatic phenomena and semiconductor technology.

Prof. Koichi Takaki (Iwate Univ.)
“Production of high-current glow plasma for high-speed material process”
Pulsed power technology was employed to generate a glow discharge with a large current exceeding 100 A. The gas pressure was varied from atmospheric pressure down to 10 Torr. The glow‐sustaining time was estimated using input energy density in cathode fall region. The electron density of grow plasma increased from 1010 to 1011 cm⁻³ at transient of glow mode from normal to abnormal. Global model analysis indicated a significant shift in the balance of ion and excited-state species near the transition from the normal to abnormal. The carbon film was prepared using the pulse glow.

17:00-17:15 Research Presentation (5)
Mr. Toshio Uehara (TTY. Ltd., Visiting researcher of Nihon University College of Science & Technology, Former CEO of Trek, Inc. and President Trek Japan K.K.)
“Introduction of High Voltage Electrostatic Force Microscopy (HV-EFM)” The precise characterization of surface voltage distributions on charged surfaces with high spatial resolution is critical for a wide range of scientific and technological applications. Conventional electrostatic voltmeters typically provide spatial resolutions no finer than approximately 1 mm in diameter, which constrains their ability to resolve localized charge variations. To overcome this limitation, we have developed a high-voltage electrostatic force microscopy (EFM) system that achieves spatial resolutions on the order of 10 µm in diameter. The instrument accommodates measurement voltages from 0 to ±2 kV and supports scanning areas extending over several square centimeters. This apparatus enables the detailed and accurate mapping of surface potential distributions with substantially improved resolution relative to existing measurement techniques.

“Electrical Behaviors & Standardization of Submicron Bubbles for a Sustainable Humanosphere” (Prof. Ueda)
https://www.rish.kyoto-u.ac.jp/center_future/unit/unit3/
We present how international standardization and research design for fine and ultrafine bubbles intersect to advance a sustainable humanosphere. Impedance spectroscopy and compact equivalent-circuit models resolve Maxwell-Wagner-Sillars polarization, linking interfacial charge and zeta potential to radical generation and pollutant removal. We propose ISO-aligned, practical metrics for electrical characterization to guide scalable, energy-efficient applications.
