S. Tohno et al., PRODUCTION OF CONTACT-FREE NANOPARTICLES BY AEROSOL PROCESS - DEPENDENCE OF PARTICLE-SIZE ON GAS-PRESSURE, Journal of colloid and interface science, 180(2), 1996, pp. 574-577
Experiments were made to determine the dependence of the size of conta
ct-free nanoparticles produced by aerosol process on gas pressure. The
particles were collected as contact-free dispesoids in hexane with a
cationic surfactant, and the geometric mean sizes were below 10 nm in
diameter, It was found that the size increased linearly as the pressur
e was raised from 0.04 to 1.43 kPa for Ag, Bi, Cu, and Te. Similar slo
pes were obtained for the linear function between size and gas pressur
e except for Te. (C) 1996 Academic Press, Inc.
