Plasma synthesis and treatment of copper-based nanopowders

Cu-based nanoparticles with different morphologies were prepared via submerged elec- trical discharge of bulk copper and graphite electrodes in a CuCl2 aqueous solution. The synthesized material was subjected to laser-induced modification. The influence of discharge parameters and electrode compos...
