Front Cover: Non‐thermal high‐aspect‐ratio atmospheric‐pressure Ar microplasmas are generated inside capillaries of inner diameter 4–100 μm. The effects of the diameter on the discharge ignition and the plasma properties are investigated. As the diameter decreases to 9 μm, the current density and the electron density reach up to 3.5×10 9 A/m 2 and 11×10 16 cm −3 , respectively. This study may be useful in plasma medicine, UV radiation sources, and the inner surface modification of microtubes. Further details can be found in the article by Shuqun Wu, Fei Wu, Chang Liu, et al. ( e1800176 ).
