Advanced Functional Materials, EarlyView.A circular route, involving upcycling of waste surgical masks, affords a Mn‐based layered carbide with porosity, redox activity and low work function. These features enable its effective operation as positive supercapacitor electrode in an aqueous asymmetric supercapacitor delivering 213 Wh L−1 energy density.

Varying Synthesis Parameters of Potato Starch Aerogel for Aerospace Applications
GelsAerogels have the potential for usage in many daily and high-tech aerospace applications. Silica aerogels are fragile, while organic aerogels are much tougher, but they are both generally synthesized using toxic solvents.
