Tunable Functionality and toxicity studies of Titanium Dioxide Nanotube Layers [PDF]

, 2010
In this work, we have developed economic process to elaborate scalable titanium dioxide nanotube layers which show a tunable functionality. The titanium dioxide nanotube layers was prepared by electrochemical anodization of Ti foil in 0.4 wt% hydrofluoric acid solution.
