The structural features of the porous type of anodic oxide coating applied to aluminum have been investigated with the electron microscope. These coatings consist of close‐packed cells of oxide, predominately hexagonal in shape, each of which contains a single pore. Pore size is a function of the electrolyte used and is independent of forming voltage. Wall thickness and barrier thickness are primarily a function of forming voltage and are affected to a minor degree by the electrolyte type. Pertinent dimensions of anodic coatings formed in sulfuric acid, oxalic acid, chromic acid, and phosphoric acid electrolytes are presented, and formulas are given for calculating the cell size and pore volume of these coatings.read more

Growth and properties of gold and nickel nanorods in thin film alumina
Paul R. Evans,William Hendren,Ron Atkinson,Gregory A. Wurtz,Wayne Dickson,Anatoly V. Zayats,Robert Pollard +6 more
TL;DR: In this article, a method for varying the diameter of the nanorods whilst keeping the spacing constant was demonstrated for the optical extinction spectra for the gold and nickel nanorod, and it was shown that the magnetic properties are governed by both interactions between wires and shape anisotropy.

Supramolecular Organization of Polymeric Materials in Nanoporous Hard Templates
TL;DR: In this paper, the mesoscopic structure of nanotubes by controlling the way precursors and target materials are deposited into the nanopores is reviewed, and specific attention is directed to structure formation processes such as crystallization, phase separation and mesophase formation underthe influence of the two-dimensional confinement imposed by the pore geometry and the interfacial interactions with the Pore walls.

Preparation of photonic crystals made of air pores in anodic alumina
TL;DR: In this article, the existence of a photonic band gap in the optical sprectrum for anodic alumina was proved by optical photographs and transmission spectra, which could provide a possible approach to produce large-area optical photonic crystals cheaply and rapidly.
