Monodisperse nanometer size silver particles as small as 1 nm were gen
erated by a new differential mobility analyzer and an IR ray furnace a
t a concentration higher than 10(3) cm(-3). The test nanometer size pa
rticles were introduced into stainless steel wire screens and circular
aluminum tubes to investigate the particle rebound on solid surfaces.
As a result, it was found that the particle rebound may increase the
particles penetration through circular tubes when the particles are sm
aller than 2 nm.
