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.
Consistent particle deposition & localization in leaf structures. 様々な葉の構造で一貫した粒子の沈着と局在
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.
After spraying of water-soluble particles on a crop (komatsuna). 小松菜に水溶性微粒子を散布していた後は?
Ammonium sulfate particles deposited on the leaf deliquesced, allowing ions such as SO42− in the solution to be absorbed into the leaf. サブミクロン硫酸アンモニウム粒子が葉表面に堆積し、脱離溶液中のSO42−などのイオンが葉に吸収される可能性が高い。
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? We learn an engineering thing.
Epicuticular “wax” crystals affect distribution of incoming aerosol 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、微粒子の付着を防止する役割?
Aerosols deposit behind the sheet (Plant leaf model)?(植物葉モデル)薄板の裏側までエアロゾルが沈着する?
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”…
