口腔から発せられた微粒子と換気 Particles from the mouth & Ventilation
Air flow and ventilation or air purifiers are necessary to expel aerosol particles floating in closed spaces!「閉空間に漂うエアロゾル粒子を追い出すには空気の流れと換気・空気清浄機が必要です!」
From a single candle, both hydrophilic & hydrophobic layers could be produced/ 一本のロウソクから親水性と疎水性の両方の粒子層が作製できた
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？
Does the leaf structure prevent the aerosol deposition?植物葉の構造はエアロゾルの沈着を妨げるのか?
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。

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。
