Cover: A new strategy is proposed for the preparation of epoxy nanofibers from small molecules, which is based on the combination of coaxial electrospinning (for providing core/sheath nanofibers as templates), hot curing (for cross‐linking within the core part), and selective removal of the sheath polymer. Further details can be found in the article by X. Wang,* W.‐J. Zhang, D.‐G. Yu,* X.‐Y. Li, and H. Yang on page 664.
