Synthesis process and resultant products.

Panel (a), schematic synthesis of shapes-modified superlattice PdCu NWs. I, pre-electrodeposited PdCu NWs released by dissolving AAO template. II, partially etching Cu. Panel (b), the resultant products obtained with III random-chapped, IV random-gapped, V screw-threaded and VI spiral shapes.
