Prolonged Cell Encapsulation and Gravity‐independent Filamented Light Biofabrication of Muscle Constructs

Advanced Science, EarlyView.
A gravity‐independent filamented light (G‐FLight) projection method is presented for rapid biofabrication of anisotropic tissues, demonstrated with muscle constructs as a target application. Specialized photocrosslinkable resins enable refrigeration or cryopreservation with encapsulated cells.

Iron‐Based Catalysts for the Removal of Microplastics

Advanced Energy and Sustainability Research, EarlyView.
Microplastics (MPs) are some of the newer environmental dangers and are still in need of optimal treatment. Iron‐based compounds can be used as catalysts for the removal of MPs due to the iron abundance, sustainability, and catalytic versatility. This review presents the current status of iron‐based materials for the photocatalytic, Fenton process, and
