“…Based on the conductance change of the atomic scale silver junction, we proposed that there were some silver ions on the surface of silver quantum wires. Today, as an important member of one-dimensional magnetic materials, the iron-based nanostructured materials not only show the superior magnetic properties, but also draw extensive attention in biomedical applications owing to the wide application prospects in medical diagnosis and treatment, resulting from the high saturation magnetism and superior biocompatibility [11][12][13]. In this full paper, the surface microstructure characteristics of Fe quantum wires are studied in an aqueous environment, and the interaction mechanism between Fe quantum wires and specific molecules is discussed.…”

The surface structural characteristics of Fe quantum wires prepared by two electrochemical methods in solution were studied by their conductance changes caused by the interactions between the quantum wires and specific molecules. Once ascorbic acid was added into the solution, the conductance of the Fe junction decreased to a lower value while for the dopamine adsorption, the conductance showed no obvious change. We proposed that there were some iron(II) ions on the surface of atomic-scale Fe junction, not iron(III) ions, and these iron(II) ions played a significant role for the conductance change. This mechanism was further enhanced by the following two experiments. When exposing the quantum wire to sodium borohydride, the conductance increased to a higher value, and the conductance increase was also observed with an electrochemical reduction process, which provided additional evidence for the proposed mechanism.

“…Arrays of nanowires can be obtained by filling a porous template that contains a large number of straight cylindrical, nano-size diameter holes, by various techniques including electrodeposition [15], chemical vapor deposition [24], FIBinduced deposition [25], or molecular beam epitaxy [26]. Among all of these approaches, electrodeposition has been widely applied for the fabrication of nanostructures at different length scales, including the nanometric regime.…”

Background: Quasi-one dimensional nanostructures: nanowires, nanotubes, nanorods, nanobelts/nanoribbons and complex "nanowire-nanoparticle" composites have been synthesized over the years. These nanostructures are particularly appealing due to their specific properties defined by their high aspect ratio: two dimensions are in the nanoscale range and one dimension is in the microscale. Methods:One of the well-designed approaches for the synthesis of such nanostructured materials is template-assisted fabrication combined with electrodeposition. The fabrication approaches for the growth of iron-group alloy nanostructures inside nanoporous oxide membranes by means of different electrodeposition techniques, and the resulting unique properties and potential applications of this type of materials are reviewed. Results:Arrays of nanostructures can be obtained by filling a porous oxide template that contains a large number of straight cylindrical, nano-sized diameter holes. Generalities of metals electrodeposition into nanoporous oxide membranes are discussed. Measures to minimize the nonuniformity of deposits inside pores need to be addressed to thin the barrier layer, to control hydrogen evolution and to improve mass transport inside the pores. Examples of binary and ternary iron group alloys grown inside nanoporous oxide templates are provided. Catalytic hydrogen evolution and methanol oxidation on the nanowires arrays are described. The "sample size effect" on the magnetic properties of materials and the electrodeposition of multilayered structures necessary for giant magnetoresistance (GMR) are discussed in details. Conclusion:Electrodeposition of binary and ternary iron-group alloys confirm that controlling alloy composition inside nanopores is still a challenge. composites [7] have been synthesized over the years. These nanostructures are particularly appealing due to their specific properties defined by their high aspect ratio: two dimensions are in the nanoscale range and one dimension is in the microscale. One of the well-designed approaches for the synthesis of such nanostructured materials is template-assisted fabrication combined with electrodeposition, first reported by Possin [8] in track etched mica films, and expanded upon by others with different materials and templates [2,[9][10][11][12][13][14]. However, the self-organized porous anodic aluminum oxide (AAO) membrane has become one of the most often used templates for tunable synthesis of different nanostructured materials [15,16].
