Aerosol characterization nanoparticle aerosols

Additionally, the NOSH Consortium was able to achieve the vast majority of its objectives, including the definition of synthesis methods for stable sources of aerosol nanoparticles of Si02, Ti02, citric acid, silver, and PSL. The PSL particles were particularly important as a calibration standard for several aerosol instruments. The aerosol instrument characterization was successfully completed for numerous aerosol instruments, including the long- and nano-differential mobility analyzers, electrostatic-based impactor, aerosol chargers and neutralizers, and optical and electrostatic detectors.

Several aerosol nanoparticle reactors have been built and characterized in which one or more convenient process parameters can be used to control the particle size distribution, including particle diameter and number concentration. To address the diverse needs of the NOSH Consortium membership, various aerosol nanoparticle synthesis methods have been employed, including thermal decomposition of hquid precursor vajxrrs, spray atomization of hquids of soluble materials or solid susjjensions, and thermal vaporization of solid metals. These aerosol nanoparticle reactors are used in subsequent NOSH Consortium activities as detailed in the remaining...

The nanoparticles have been synthesized in different microemulsion systems. Some of them are shown in Fig. 1. The anionic Aerosol-OT (AOT)/ heptane/water system is one of the best characterized microemulsions [8,9]. The system AOT/ -xylene/water [10] has also been used. The cationic ce-tyltrimethylammonium bromide (CTAB)/hexanol/water system contains hex-anol, which forms the organic phase and plays the role of cosurfactant [11]. The nonionic penta(ethylene glycol)-dodecylether (PEGDE)/hexane/water was studied by Eriberg and Eapczynska [12]. The reverse micellar droplets have a cylindrical shape in which the surfactant molecules are parallel to each other, forming a bilayer impregnated with water. Triton X-100...
