開発の事例：微粒子の合成と構造化 Example of Technology: Synthesis & Structuring of Particles (2018-2019)
浮遊する微粒子の構造化と集積化について、従来まで考証されていなかった物質の輸送に対する「駆動力のバランス」の視点からの技術手法を開発した。We have developed methods for synthesis & structuring suspended particles from the viewpoint of “balance of the driving force on the transport of matter”, which has not been considered before.

Surface modifications have been conducted by coating the nanoparticles with silica by a one-step synthesis in dilute sodium silicate solution. 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。
Deposition process of aerosols into forest/ 森林へのエアロゾル沈着過程を解明
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。
