Professor Tatsuya Kikuchi's research lab specializes in advanced electrochemical materials synthesis, particularly focusing on anodic oxidation of aluminum to create novel nanostructured materials. The lab explores innovative electrolytes—such as pyrophosphoric acid and acetylenedicarboxylic acid—to fabricate unique anodic oxide morphologies, including nanofibers and branched porous alumina, expanding the family of anodic oxides beyond conventional barrier and porous types. The lab also integrates nanofabrication with functional applications, such as 3D microstructuring using electroplating and laser-assisted patterning, and contributes to remote educational technologies through high-speed networked laboratories. Their work bridges fundamental electrochemistry with practical nanotechnology applications in electronics, sensors, and advanced manufacturing.

Anodizing of aluminum and its alloys is widely investigated and used for corrosion protection, electronic devices, and micro-/nanostructure fabrication. Anodizing of aluminum in acidic solutions causes formation of porous aluminum oxide films, which consists of numerous hexagonal cells perpendicular to the aluminum substrate, and each cell has nanoscale pores at its center. Recently, highly ordered porous aluminum oxide has been widely investigated for various novel nanoapplications. In this rev
Anodic oxide fabricated by anodizing has been widely used for nanostructural engineering, but the nanomorphology is limited to only two oxides: anodic barrier and porous oxides. Therefore, the discovery of an additional anodic oxide with a unique nanofeature would expand the applicability of anodizing. Here we demonstrate the fabrication of a third-generation anodic oxide, specifically, anodic alumina nanofibers, by anodizing in a new electrolyte, pyrophosphoric acid. Ultra-high density single n
The objective of this study is to investigate a remote laboratory on electric motors using high-speed networks between Japan and the United States. The client, situated at Stanford University, Stanford, CA, accessed the remote laboratory system set up in Japan. Through this client, the remotely located user operated the motors and conducted experiments. The remote laboratory was conducted over a high-quality digital video conference system, making it possible for both sides to communicate smooth
