Chemical-coating of clay-based soil particles slows water evaporation. World’s 1st. 粘土系土壌粒子の化学コーティングは水の蒸発を遅らせる。世界初。

Plastic sheeting is commonly used to conserve water in crop production, but its waste has become a challenge. We report that a silane coupling agents-based coating can be applied to natural clayey soil samples to suppress water evaporation. 一般的に作物の生産で水を節約するために、プラスチックのシートが使われているが、その廃棄物が課題となった。本研究では、水の蒸発を抑制するために、天然の粘土質土壌にシランカップリング剤系コーティングが適用できることを報告している。

Micrometer-sized “wet” aerosols on to a hydrophilic surface. 数μmのwetエアロゾルが親水性表面にどのように沈着するのか？

大気に浮遊する微粒子の沈着の場所について考えてみた。”Wet”微粒子は「親水性の高い」場所に多く沈着する。”Dry”微粒子”は「親水性の低い」場所に多く沈着する。Considered the location of the deposition of particles suspended in the air. The results: “More hydrophilic” area trapped more “wet” particles. The “less hydrophilic” area trapped more “dry” particles.

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…
