A method of growing mushroom or shell like nanostructured metal convexconcave models has been worked out. Silver,copper,nickel,rhodium andPd-Ni,Pd-Co alloy structures are reproduced as a result of self-assembly ofnanowires growing on porous membranes in the course of pulse currentelectrodeposition. It is shown that the method allows to model not only theshell shape but also the hierarchical structure at the nano, micro andmesolevels. A 1,2 mm sized shell was grown from Pd-Ni alloy. The architectureof the models was studied by fragmentation and chemical etching. The imageswere obtained using SUPRA 50 VP and JEOL scanning electron microscopes. Themetal shell is a bowl-shaped frame, its walls composed of densely packednanoelements. Each nanoelement is a conical bundle of nanowires grown as asupported wine glass. The shell inner surface is a weave of nanowires with avegetation pattern with bottom up directed lines. The inner surface exhibitsalso well pronounced transverse rings formed by the bottom up growing bundlesof nanowires that compose the shell frame. A number of nanowire bundle endsrise to the shell outer surface as nanoflowers that can serve as templates forgrowing nanowires. In some cases the nanowires growing on the outer surfaceform a copy of plate mushroom. A hypothesis is proposed that pulsed growth onmembranes is a tool of morphogenesis of many mushrooms and plants.
