title: Novel AAO films and hollow nanostructures fabricated by ultra-high voltage hard anodization.
abstract: Novel anodic aluminium oxide (AAO) films and hollow nanostructures were synthesized via a simple electrochemical and chemical etching route; fluctuating nanotube growth inside AAO film fabricated under ultra-high voltage was considered to be the main reason for the formation of such new structures.
