Growth of anodic alumina nanopores and titania nanotubes and their applications
… The formation mechanism of anodic TiO2 nanotubes is proposed in this dissertation. Moreover, FIB pre-pattern guided anodization is introduced to synthesize highly ordered TiO₂ nanotubes with different morphologies. The effects of inter-tube distance and arrangement to the structure of …

Nanopore/Nanotube Pattern Formation through Focused Ion Beam Guided Anodization
… to make highly ordered anodic porous alumina and titania nanotubes. Focused ion beam guided porous anodic alumina is carried out by pre-designing hexagonal and square guiding patterns with different interpore distances on well electropolished Al foil before anodization. After anodization, the …

Development of Reactor Technology for the Photoelectrolysis of Seawater
… materials such as sol-gel photoanodes and titania nanotubes have been shown as immobilised photocatalysts capable of chloride oxidation with the latter exhibiting higher faradaic efficiencies of ~ 60 % under UV illumination. A propeller reactor system has been developed for application as a …

Multifunctional hybrid sol-gel implant coatings on anodized titanium substrates to improve osseointegration and antimicrobial effectiveness
… coating adhesion and surface wettability, titania nanotubes (TNTs) developed on the surface of titanium implant substrates by anodizing treatment, are proposed as an interface between the titanium substrate and outer coating. Further, to facilitate controlled and sustained release, an …
