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).

Award: Charging state of particles collected from air 大気中から捕集した粒子の帯電状態を調べた(学会賞)

呼吸により人体に入る微粒子の帯電状態が注目された。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

Deposition process of aerosols into forest/ 森林へのエアロゾル沈着過程を解明

Particulate matter strongly adsorbed onto leaf surfaces is not washed away by rainfall and contributes to the EC (Elemental Carbon) flux. Leaf-surface particles must be included when evaluating the dry and total fluxes of particulate matter, in particular for water-insoluble constituents such as EC. 葉面に強く「付着」した粒子状物質は降雨によって洗い流されず、EC(元素炭素)フラックスに寄与する。粒子状物質、特にECのような水不溶性成分の乾燥流束および全流束を評価する場合には、葉表面粒子を含めなければならない。
