Resistance to collapse: Spherical vs. non-spherical particles. 球形が崩壊しにくい?微粒子(数百nm領域)では世界初の検証。
The resistance to collapse of agglomerated submicron particles was investigated. The world’s first. 凝集したサブミクロン粒子の崩壊に対する抵抗性を調べた研究。世界初。
Low-power ultrasonic cleaner challenged the “submicron” particle detachment. 難問の「数百nm粒子の剥離」に低出力の超音波洗浄機が挑戦した
数百nmの粒子が堆積された基板を「特別な」スス粒子が含まれている水系懸濁液に超音波法を利用した微粒子回収法・洗浄法が提案された。Aqueous samples can be prepared by a novel method for detaching submicron particulates deposited on substrate.
Low-cost, portable, aerosol sensor/ 低コスト・携帯型、エアロゾル計測器の開発
Arduino-based real-time PM10 sensor, with temperature and humidity. マイクロコントローラArduinoを用いたオンラインPM10 (10μm未満の粒子状物質) 測定を開発。数1000 μg/m3 の濃度も測定可。
Can aerosol particles deposit from 25℃ to 40℃ surfaces?【医療機器の開発】室温中のエアロゾルを40℃の表面に沈着させる流体制御
閉鎖空間における沈着を考慮したエアロゾルフローシステムを構築した。沈着効率が悪い従来法に代わって本手法を気液界面細胞曝露に応用できれば有用である。An aerosol flow system has been constructed to mimic the delivery of particles to the air-liquid interface. Potentially be applied for the deposition and analysis of submicron particles on various types of substrate without the need for vacuum imaging analysis..

Visited Central Research Institute of Electric Power Industry. 【見学】電力中央研究所
18 Dec. 2015 After a lunch time (Turkish food) around Kamakura station; we (12 students) visited Central Research Institute of Electric Power Industry (電力中央研究所) in Yokosuka city (Kanagawa prefecture). Since 2008, some of lab’s members have been collaborating with CRIEPI on measuring particulate matters (PM) at the exhaust of coal-based power plant. Thanks to Noda…
Joint Seminar with School of Agriculture Labs 農学府の研究室と合同セミナー
14 Dec. 2015: Two of our students have presented their studies at a joint seminar with Hatakeyama Lab and Matsuda Lab. Place: FM Tama Kyuryo (Matsuda Lab) More than four students have also visited FM Tama Kyuryo (an experimental “forest” of TUAT sites) in November 2015, for the rain water samples.
【環境計測技術】表面電位顕微鏡で大気中から捕集した粒子の帯電状態を調べたCharging state of particles collected from the air by K-F Microscope.
呼吸により人体に入る微粒子の帯電状態が注目された。本研究では大気中に浮遊する微粒子の帯電状態を評価できる手法を考案。The importance of electrostatic charging state to particle deposition in the human airways has been suggested. We developed a measurement method of electrostatic charging state of individual ambient aerosol particles
