Back Cover: Hierarchical nanoporous anodic alumina templates by asymmetric two-step anodization (Phys. Status Solidi A 3/2011)
In their article on pp. 668–674, A. Santos, J. Ferré-Borrull, J. Pallarès and L. F. Marsal report an asymmetric two-step anodization process which is used to fabricate hierarchical nanoporous anodic alumina templates. The cover picture illustrates an atomic force microscopy (AFM) 3D image of a nanostructure consisting of an outer hexagonal lattice of concavities in the interior of which nanopores grow. The modification of the different anodization parameters makes it possible to control the fabrication process and obtain hierarchical nanoporous anodic alumina templates with a wide range of morphologies and applications.
