親水性表面への数μmのエアロゾル液滴の沈着 Micrometer-sized aerosols/ droplets on a hydrophilic surface

Droplet generator: Ultrasonic nebulizer (1.7 MHz). Micrometer sized sprayed droplets include silica nanoparticles (average particle diameter of 145 nm). A single substrate with areas having different “level” of hydrophilicity was used as a model surface. A low-pressure analysis method (electron-microscope SEM) and ordinary (1 atm) pressure methods (Raman spectroscopy and X-ray fluorescence) analytical results indicated…

同一ロウソクから親水性と疎水性の両方の粒子層が製造可能 From a single candle: we can make both hydrophilic & hydrophobic layers.

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?
