Front Cover: The fabrication of polymer fibers with anisotropic cross‐sections is achieved by pressing electrospun polymer fibers with flat or patterned substrates while the samples are thermally annealed. The shapes and morphologies of the pressed polymer fibers are controlled by the experimental conditions. Hierarchical polymer fibers with nanorods can also be fabricated by pressing the fibers with porous anodic aluminum oxide templates. Further details can be found in the article by J.‐T. Chen*, Y.‐H. Kao, T.‐Y. Kuo, J.‐T. Liou, Y.‐J. Chiu, C.‐W. Chu, M.‐H. Chi, and C.‐C. Tsai on page 239.
