title: Multiple nano-blast synthesis of PT/8Y-ZP composite nanopowders.
abstract: We demonstrate a processing technique based on the synthesis of ceramic nanopowders and simultaneous impregnation with metallic nanoparticles by multiple 'nano-blasts' of embeded cyclotrimethylene trinitramine in preliminary engineered multi-component nano-reactors. 'Nano-blasts' of impregnated cyclotrimethylene trinitramine deagglomerate the nanopowder due to the high energetic impacts of the blast waves, while the decomposition of compounds and their solid-solubility is enhanced by the extremely high local temperature generated during the nano-explosions. We applied this technique to produce nanosized agglomerate-free 8 mol% yttria-doped cubic zirconia aggregates with an average size of 53 nm impregnated with 10 mass% of platinum particles of 2-14 nm.
