植物に水溶性微粒子を2年間与えていたら?Effect of water-soluble particles on growth of plants (2 years experiment)

JOURNAL: Atmospheric Environment (2014) http://www.sciencedirect.com/science/article/pii/S1352231014000405 Effects of 2-years exposure to (sub-micron) ammonium sulfate particles on growth and gas exchange rates of Fagus crenata (ブナ), Castanopsis sieboldii (スダジイ), Larix kaempferi (唐松) and Cryptomeria japonica (スギ) seedlings •No significant effect of the particles on growth was observed after 2 years. •Net photosynthetic rates of 3 species were not significantly changed….

電気化学法で合成した磁鉄鉱ナノ粒子の熱安定性 Thermal stability of magnetite particles made by an electrochemical method,

Magnetite nanoparticles have been prepared by electrooxidation of iron in water. Surface modifications have been conducted by coating the nanoparticles with silica by a one-step synthesis in dilute sodium silicate solution. 水中の鉄の電気酸化によってマグネタイトナノ粒子を調製した。希薄ケイ酸ナトリウム溶液中での一段階合成によりナノ粒子をシリカで被覆することにより表面改質を行った。

森林への大気中微粒子の沈着過程. Deposition process of particles into forests

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。
