Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish. Aluminum is ideally suited to anodizing, although other nonferrous metals, such as magnesium and titanium, also can be anodized. The anodic oxide structure originates from the aluminum substrate and is composed entirely of aluminum oxide. This aluminum ox...

Anodic porous alumina has broad applications for fabricating self-assembled nanostructures, for which atomistic understanding of ionic transport at pore surfaces is indispensable. Here, molecular-dynamics simulation of amorphous alumina with a cylindrical pore under electric field shows correlated anion (oxygen)-cation (aluminum) transport at the pore surface, as opposed to ordinary drift motio...

Artificial hemoprotein nanotubes have been prepared by a layer-by-layer deposition technique with human serum albumin (HSA) incorporating the synthetic heme (FeP) [HSA-FeP] using an anodic porous alumina template; each of the liberated tubules has a very uniform outer/inner diameter and can reversibly bind dioxygen (O(2)) at 25 degrees C.

A mussel-inspired new interfacial ionic rectification device is fabricated using porous anodic alumina nanochannels and graphene oxide via dopamine polymerization. In addition, the rectification mechanism is elucidated based on the principles of physics and thermodynamics via finite element simulation and the results show that the interface distance and surface charge play a vital role in ion t...

Clinical long-term osteointegration of titanium-based biomedical devices is the main goal for both dental and orthopedical implants. Both the surface morphology and the possible functionalization of the implant surface are important points. In the last decade, following the success of nanostructured anodic porous alumina, anodic porous titania has also attracted the interest of academic researc...

A highly-stable and biocompatible nanoporous electrode is demonstrated herein. The electrode is based on a porous anodic alumina which is conformally coated with an ultra-thin layer of diamond-like carbon. The nanocarbon coating plays an essential role for the chemical stability and biocompatibility of the electrodes; thus, the coated electrodes are ideally suited for biomedical applications. T...
