À1 at 5 mV s À1 was observed for the flake-like structure, which is higher compared to that of the wire-like structure. The flake-like MnO 2 nanostructure exhibited an excellent long-term stability, retaining 81% of initial capacitance even after 4000 cycles, whereas for the wire-like MnO 2 nanostructure, capacitance decreased and the retention value was only 70% over 4000 cycles. In the future, the present approach can be extended for the formation of other oxide-based materials using DNA as a promising scaffold for different applications such as homogeneous and heterogeneous organic catalysis reactions, Li-ion battery materials or for the fabrication of other high performance energy storage devices.

“…Nanowires can be obtained by selectively electrodepositing metals or conductive metal oxides at the step edges on an HOPG (Highly Oriented Pyrolytic Graphite) surface [8,9]. The technique of using step edges as a template to synthesize nanowires, sometimes called ''step edge decoration (SED)'', has been known for many years [10][11][12][13].…”

In order to fabricate effective Pd-Ni alloy nanowire arrays with given compositions and size, the process of nucleation and growth and the dependence of alloy composition on deposition potential were investigated. The results reveal that the compositions and sizes of Pd-Ni alloy nanowires can be controlled within a desired range through adjusting suitable nucleation and growth potentials as well as the time. The Ni content in the alloy nanowires was found to vary from 6 to 28% when the deposition potential was changed from -0.3 to -1.9 V. A growth potential of -0.35 to -0.50 V was applied to fabricate Pd-Ni alloy nanowires with 8-15% Ni content. Continuous and parallel nanowire arrays can be successfully fabricated when nucleation is performed at a potential of -1.2 V for 50 ms with further growth at -0.45 V for 800 s. Pd-Ni crystal phases exist in the alloy structure forms of h111i, h200i, h220i, h311i. The nanowires have an average diameter of 150 nm and a length of 100-450 lm.
