Self‐Ordering of Cell Arrangement of Anodic Porous Alumina Formed in Sulfuric Acid Solution.
TLDR
In this paper, self-ordering of the cell arrangement of the porous structure of anodic alumina has been studied in a sulfuric acid solution, and a highly ordered structure was obtained under anodization at a constant potential of 25 to 27 V.Abstract:
Self-ordering of the cell arrangement of the porous structure of anodic alumina has been studied in a sulfuric acid solution. Ordering of the cell arrangement was dependent on the applied potential, and a highly ordered structure was obtained under anodization at a constant potential of 25 to 27 V. Self-ordering of the porous structure proceeded with the growth of the oxide layer under anodization at an appropriate potential, and a porous film with an almost ideal hexagonal honeycomb structure was formed over an area of several micrometers after a long period of anodization.read more

Fast fabrication of long-range ordered porous alumina membranes by hard anodization
TL;DR: A new oxalic-acid-based anodization process for long-range ordered alumina membranes that establishes a new self-ordering regime with interpore distances, (Dint)=200–300 nm, allowing 2,500–3,500% faster oxide growth with improved ordering of the nanopores.

Fabrication of pillar-like titania nanostructures on titanium and their interactions with human skeletal stem cells
TL;DR: Titania nanopillar structures with heights of either 15, 55 or 100 nm were produced on Ti surfaces using anodization through a porous alumina mask and resulted in the greatest cell response with bone matrix nodule forming on the Ti surface after 21 days.

Self-ordered anodic aluminum oxide formed by H2SO4 hard anodization.
TL;DR: The anodization procedure previously employed for oxalic acid HA (H2C2O4-HA) is modified to suppress the development of cracks and to fabricate mechanically robust AAO films with D(int) values ranging from 78 to 114 nm.
