Guoxiu Tong, Jianguo Guan and Qingjie Zhang Nanotube Arrays: In Situ Generated Gas Bubble-Directed Self-Assembly: Synthesis, and Peculiar Magnetic and Electrochemical Properties of Vertically Aligned Arrays of High-Density Co3O4 Nanotubes (Adv. Funct. Mater. 19/2013) Advanced Functional Materials 23
The simple, versatile, and large-scale fabrication of vertically aligned nanotube arrays (NTAs) is achieved by regulating the gas bubbles in situ generated from the thermal decomposition of melted salts. On page 2406, Jianguo Guan and co-workers report that as-obtained Co3O4 NTAs show unique magnetic properties and significantly enhanced electrochemical activity, and are promising for magnetic recording media, magnetic shielding, lithium-ion batteries, and chemical sensing.
