PAPER: Can particles move and deposit, from 25 to 40 deg-C surface? ~40℃表面に微粒子を集積させた流体の制御技術

Why 40 deg. C ?  This study considered the deposition of submicron particles on living-cell or “human-body”-modelled surface.

Why a fluorescence microscope? Because other analytical tools such as SEM, need low pressure or vacuum condition, which is not “good” for living-system.

空気・液体界面への粒子の輸送を模倣するために、エアロゾル・フロー・システムが構築された。An aerosol flow system has been constructed to mimic the delivery of particles to the air-liquid interface. Continue reading PAPER: Can particles move and deposit, from 25 to 40 deg-C surface? ~40℃表面に微粒子を集積させた流体の制御技術

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。


light-1551386_960_720Using “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?

PAPER: Spraying water-soluble particles to komatsuna leaves. 小松菜に水溶性微粒子を散布したら・・

Short Introductions of /our papers/


Free-access (until Dec. 1, 2017): elsevier.com

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 solution to be absorbed into the leaf. 葉表面に堆積した粒子の量は時間とともに減少した。サブミクロン硫酸アンモニウム(AS)粒子が葉表面に堆積し、脱離溶液中のSO42−などのイオンが葉に吸収される可能性が高い。

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。 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?
