Abstract :

The architecture of novel 3D- mesoscopic structures obtained via self-organization of growing metallic nanowires has been investigated. Seashell-, fungus- or lotus leaf-shaped structures are reproducibly formed by means of programmable pulse current electrodeposition on porous membranes. Nanostructured mesostructures of various metals (Ag, Cu,Pd, Rh, Ni), alloys (PdNi, PbIn), and topological insulator Bi2Se3 were obtained. The sample size was reached several mm. SEM investigation has revealed that the frame of the metallic â�?�?seashellâ�? presents a hierarchical system with elements of fractal self-similarity at the nanoand micro-levels. The frame is a volumetric multilayer net composed of conical bundles of nanowires as building blocks. TEM study showed that the Pd-Ni nanowires have periodic bulges (â�?�?beadsâ�?), a V-shaped branching, and a unique structure kind of a "Finemet", i.e., the amorphous matrix with nanocrystallites dispersed therein. In perspective, the proposed technique can be used as a 3D printer for the purposeful synthesis of new materials for medicine (sensors), catalysis, nanodevices based on mesostructures with the complex quantum nanoarchitecture.
