Full text not available from this repository.


A concept for a new shock-wave reactor for producing nanoparticles starting from the gas-phase is presented. Preliminary studies of the gasdynamic behavior of the shock system, the precursor mixing and the water injection have been carried out numerically and in experiment. The gained knowledge is utilized to design and build up a pilot facility for experimental studies, including the generation of nanoparticles.
