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

Linear assembly of a porphyrin–C60 complex confined in vertical nanocylinders of amphiphilic block copolymer films
TL;DR: Linear assemblies of a 1 : 1 porphyrin-fullerene C60 complex were formed in vertical cylindrical polyether nanodomains of amphiphilic block copolymer films by a simple spin coating-annealing method, retaining the nanocylinder structures even with high contents of the complex in the polymer films.

Chapter 3 Pore-Suspending Membranes on Highly Ordered Porous Alumina and Porous Silicon Substrates: Preparation, Characterization, and Application
TL;DR: Preparation and characterization of pore-suspending membranes on highly ordered porous alumina and porous silicon substrates starting either from lipids dissolved in an organic solution [nano- and micro-black lipid membranes (BLMs)] or from vesicles, and impedance spectroscopy results reveal that single lipid bilayers are formed, which are extraordinary stable.
