From a candle burning, we developed assembly routes to form hydrophilic or hydrophobic layers of carbonaceous nanoparticles. ロウソク燃焼の「煤」を用いて、親水性または疎水性を有するナノ粒子膜の作製する方法を開発。5000年前に中国で開発された、従来の「墨」技術と同じかどうか？

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…
【植物とエアロゾル】葉の構造は大気汚染物質の付着を防ぐ？Does the leaf structure prevent the aerosol deposition?
Epicuticular “wax” crystals affect distribution of incoming particles on leaf surfaces. 気孔の機能を保持するために密に分布されたワックスは、気中からの微粒子の付着を防止する役割があるかもしれません。
