Example of Technology: Synthesis & Structuring of Particles (2018-2019)開発の事例:微粒子の合成と構造化

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.

From a single candle: we made both hydrophilic & hydrophobic particle layers. 同一ロウソクから親水性と疎水性の両方の粒子層を作りました

Using “soot” from a candle burning, we developed assembly routes to form hydrophilic or hydrophobic layers of carbonaceous nanoparticles. ロウソク燃焼の「煤」を用いて、親水性または疎水性を有するナノ粒子膜の作製する方法を開発。5000年前に中国で開発された、従来の「墨」技術と同じかどうか?

Does the leaf structure prevent the deposition of aerosols? 葉の構造はエアロゾルの付着を防止する?

Epicuticular “wax” crystals affect distribution of incoming particles on needles (leaf surfaces). Densely distributed “wax” might prevent the deposition of sub-micron particles on the surfaces of needles to retain the function of stomata. スギ(代表的な針葉樹種)の葉表面に人工的に散布されたsub-micronの炭素系粒子の局在を調べた。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。

PAPER: Fine particles on bio-composite surface. ココナツ殻由来素材の表面に微粒子を集積

Other “intro” of papers from our lab >> /tag/paper/   HIGHLIGHTS: * Physical treatment on the biocomposite increases the surface roughness. * Single bond COOH network on the treated biocomposite promotes the particle deposition. * The network reduces the particles repulsion during the deposition process. # Bio-composite(バイオコンポジット)is a composite material formed by a matrix (resin) and…
