AB  - Nickel-titanium-oxide (Ni-Ti-O) nanotube arrays (NTAs) prepared on nearly 
      equiatomic NiTi alloy shall have broad application potential such as for energy 
      storage and biomedicine, but their precise structure control is a great challenge 
      because of the high content of alloying element of Ni, a non-valve metal that 
      cannot form a compact electronic insulating passive layer when anodized. In the 
      present work, we systemically investigated the influence of various anodization 
      parameters on the formation and structure of Ni-Ti-O NTAs and their potential 
      applications. Our results show that well controlled NTAs can be fabricated during 
      relatively wide ranges of the anodization voltage (5-90 V), electrolyte 
      temperature (10-50 degrees C) and electrolyte NH4F content (0.025-0.8 wt%) but within a 
      narrow window of the electrolyte H2O content (0.0-1.0 vol%). Through modulating 
      these parameters, the Ni-Ti-O NTAs with different diameter (15-70 nm) and length 
      (45-1320 nm) can be produced in a controlled manner. Regarding potential 
      applications, the Ni-Ti-O NTAs may be used as electrodes for electrochemical 
      energy storage and non-enzymic glucose detection, and may constitute nanoscaled 
      biofunctional coating to improve the biological performance of NiTi based 
      biomedical implants.
