Query: With no Color and Scent: Nanoflowers of Metals and Alloys   Ordered volume submicron surface structures "nanoflowers" - are obtained
while growing metal nanowires in porous membranes by means of pulsed current
electroplating. These structures occur if the electroplating is continued after
the nanowires appear on the membrane surface. Various ordered Ag, Pb, PdNi and
PbIn volume structures of complex shape resembling living plant organisms are
produced. Some of the structures are formed by spherical and ellipsoidal
nanoclusters. Membrane geometry and pulsed current electroplating parameters
are the main factors, which determine the shape formation process of these
ordered structures at the surface of porous membranes. Choosing the membrane
geometry, electrolyte composition and pulsed current electroplating parameters
one can deliberately fabricate volume ordered complex shape nano- and submicron
structures of various metals and alloys. Such objects can be of interest for
fundamental research as well as for applications in catalysis, electronics,
optics, medicine, etc.
