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…
