DEPOSITION OF NANOPARTICLES AND THEIR AGGLOMERATES FROM A LAMINAR GAS FLOW ONTO A SUBSTRATE

Two universal mechanisms of isothermal deposition of nanoparticles from a gas fl ow (Brownian diff usion and gravitational deposition) are investigated. The results of a model experiment on the deposition of nanoparticle agglomerates from a laminar gas fl ow onto a fl at substrate at room temperature are presented. Disintegration of nanoparticle agglomerates on increase in the fl ow velocity is detected.
