Spraying water-soluble particles on the crop. 作物に水溶性微粒子を散布した実験

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… Continue reading Spraying water-soluble particles on the crop. 作物に水溶性微粒子を散布した実験

PAPER: Charge of Particle by Kelvin Probe Force Microscopy. ケルビンフォース顕微鏡で粒子の帯電を計測

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
