Global challenges are always complex, so placing an excessive value on a competition will lead the world in the wrong direction. For the long term good, the winner will be meaningless. Understanding and caring about each other’s history is the key to collaborating with other countries.
【植物とエアロゾル】植物葉における水溶性粒子の局在の可視化 Localization of “Water-Soluble” Particles on Leaf Surfaces
堆積した粒子は凝集せず、葉の構造に依存性がないことを確認した
The particles were deposited on the leaves and needles in the same manner, regardless of leaf structure.
【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…
【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。
【環境技術】薄板の裏側まで微粒子が沈着?Are the particles deposited to the back of a sheet?
Simultaneous deposition of submicron aerosols onto both surfaces of a plate substrate by electrostatic forces We demonstrate one-step deposition of submicrometer-sized particles suspended in the gas-phase onto a plate type substrate using an electrostatic-assisted spray system. The particles were deposited on plate-type metallic surfaces, on both front and rear sides of the substrate. This “both-side”…
