Biologically compatible engineered nanoparticles to prevent UV radiation induced damage: NSF CBET: 0541516
Anodized titania nanotubes have shown tremendous potential in tuning the properties of oxide based catalysis and photocatalysis. Their application is mostly restricted to thin films which can be grown by a variety of thin film deposition method. Titanium films were grown using DC magnetron sputtering at RWTH Aachen University in Germany. The films grown using different deposition conditions showed remarkably different stress levels characterized by Multibeam optical stress sensor (MOS). The thin films were then anodized using similar anodization conditions and the effect of different stress levels in tuning the shape and property of anodized titania nanotubes was observed. Preliminary experiments suggest that both the diameter and the thickness of the titania nanotubes can be altered by different deposition conditions. The current voltage transients and Scanning Electron Microscopy (SEM) were used to characterize the anodized titania nanotubes.
