Anodic formation of Ti nanorods with periodic length

In this paper, one-dimensional homogeneous Ti nanorods are fabricated via selective corrosion of Ti substrate using electrochemical anodization technique. The nanorod length can be tuned periodically by tailoring the electrochemical conditions. A possible mechanism is proposed to explain the formation of Ti nanorods with periodic length.
