エアロゾル学会TAKAHASHI賞 AWARD (JAAST) “Deposition of submicron aerosols by a closed-loop flow system” 閉ループ式エアロゾル流によるサブミクロン粒子の沈着

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。Our method presented here may potentially be applied for the deposition and analysis of submicron particles on various types of substrate (i.e. air-liquid interface) without the need for vacuum imaging analysis (e.g. electron microscopy).

【植物とエアロゾル】作物・小松菜に水溶性微粒子を長期的に散布した After long-term spraying of water-soluble fine particles on a crop (komatsuna)…

Short Introductions of other papers: /paper/ Komatsuna plants were grown and exposed to ammonium sulfate (((NH4)2SO4), AS) submicron particles for 16 days (22.5 µg m−3 per day) in phytotrons. The amount of particles deposited on the leaf  decreased over time, because AS particles deposited on the leaf deliquesced, allowing ions such as SO42− in the…

【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
