Hydrophilic and hydrophobic particle layers from a single candle. 一本のろうそくから親水性と疎水性粒子膜が作れます。

Using "soot" from a candle burning, we developed two 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 airborne particles? 葉の構造は大気中微粒子の付着を防止するのか?

Other "intro" of papers from our lab >> /tag/paper/ Our results suggest that epicuticular wax crystals affect distribution of particles on needles. Densely distributed epicuticular wax crystals might prevent the deposition of sub-micron particles on the surfaces of needles to retain the function of stomata. 電界放出型走査電子顕微鏡(FE-SEM)によるスギ(代表的な針葉樹種)の葉表面に人工的に散布されたサブミクロンサイズの炭素系粒子の局在を調べました。気孔の機能を保持するために、密に分布されたエピクチクラワックス結晶は、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。 Elucidation of the mechanism of adsorption of particles suspended in the… Continue reading Does the leaf structure prevent the deposition of airborne particles? 葉の構造は大気中微粒子の付着を防止するのか?

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… Continue reading 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
