Mesoporous dual‐layer MnO 2 nanotubes with sheetlike subunits were synthesized from electrospun carbon nanofibers (CNF) through a sacrificial‐template method. In their Full Paper on page 159, which is featured on the front cover, Tianxi Liu and co‐workers discuss the parameters influencing the dimensions of the MnO 2 nanotubes including CNF diameter and reaction temperature. The as‐prepared MnO 2 nanotubes exhibited excellent cycling stability with a high specific capacitance due to the unique mesoporous tubular structure, which facilitates electron transfer and large electrode/electrolyte contact areas.
