Formation of NiO nanowires on the surface of nickel strips

Abstract In the present investigation, a simple metallographic technique has been introduced to synthesize bulk amount of nickel oxide (NiO) nanowires. These nanowires were formed on the surface of pure nickel strip, which were processed by single roll strip casting (SRSC). The length and diameter of these nanowires were in the range of 3.0–4.0 μm and 80–90 nm, respectively.
