The Cover Feature illustrates the set-up of a closed bipolar cell for the anodization of titanium foils towards TiO₂ nanotube layers. By using this kind of set-up, the two sides of a titanium foil can be anodized simultaneously in different electrolytes. TiO₂ nanotube layers with identical or different dimensions can thus be formed on both sides of a titanium foil. More information can be found in the Communication by H. Sopha et al.

封面特征：封闭双极电池中钛的无线阳极氧化 (ChemElectroChem 20/2021)

Cover Feature说明了用于将钛箔阳极氧化为 TiO ₂纳米管层的封闭双极电池的设置。通过使用这种设置，钛箔的两侧可以在不同的电解液中同时进行阳极氧化。因此可以在钛箔的两侧形成具有相同或不同尺寸的TiO ₂纳米管层。更多信息可以在 H. Sopha 等人的通讯中找到。
