Microfluidics: Flow‐Regulated Growth of Titanium Dioxide (TiO₂) Nanotubes in Microfluidics (Small 30/2017)

In article number 1701154, Jiandi Wan and co-workers, show that flow in microfluidics significantly enhances the anodic growth of TiO2 nanotubes and controls the diameter, length, and crystal orientations of TiO2 nanotubes. Strikingly, flow can manipulate the spatial distribution of nanotubes in microfluidics and produce both vertically- and horizontally-aligned TiO2 nanotubes on silicon substrates.
