Two‐Way Shape‐Memory Aerogels In article number 2102674, Meng Wang, Hong Yang, Quan Li and co‐workers report the design, synthesis, characterization and reversible deformation of an unprecedented two‐way shape‐memory liquid crystal elastomer (LCE)‐based aerogel. The LCE‐based aerogel, prepared by an orthogonal thermal and photo curing strategy coupled with an intermediate mechanical stretching step, exhibits reversible shrinking/expansion deformation during heating/cooling cycles with superior fatigue resistance. Cover story depicts Bull Demon King, a famous monster in the traditional Chinese novel Journey to the West, taking back the magic weapon plantain fan (LCE‐based aerogel) in his territory, Flaming Mountain (external stimulus).
