  2. 2. Generation of Engineered Aerosol Stainless Steel Nanoparticles using a Spark Discharge Generator

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Calle Preger; [2016]
    Keywords : aerosol nanoparticles; stainless steel; spark discharge; Technology and Engineering;

    Abstract : This diploma work has shown that it is possible to generate engineered stainless steel nanoparticles using a spark discharge generator (SDG) with a selectable size in the size range 20-70 nm in diameter. The generated particles have similar composition as the electrodes used, although further studies are needed to verify if this is true for all particles generated. READ MORE
