3D‐Printed Porous Hydroxyapatite Formed via Enzymatic Mineralization

Advanced Functional Materials, EarlyView.
Bone combines lightness, strength, and the ability to heal, inspiring new materials design. This work introduces a room‐temperature, enzyme‐mediated 3D printing method to create porous hydroxyapatite scaffolds. The process avoids energy‐intensive sintering, preserves bioactivity, and allows control over porosity and mineralization.

Indirect Band Edge and Chain‐Locked Linear Dichroism in the Quasi‐1D Van der Waals Antiferromagnet AgCrP2S6

Advanced Functional Materials, EarlyView.
AgCrP2S6 reveals a momentum‐indirect band edge (≈1.35 eV) and chain‐locked linear dichroism: the first direct transitions emerge at 1.6–1.8 eV for E||a. Resonant Raman and photoemission corroborate this assignment. In ACPS/graphene heterostructures, photocurrent turns on above ≈1.5 eV and follows the same polarization selection rules (anisotropy ≈0.53),

High Energy Density Asymmetric Aqueous Supercapacitor Based on a 2D Manganese Carbide as a Positive Electrode

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.

Bioinspired Polypeptide Dendrimer‐Modified Thin‐Film Composite Membranes for Selective Lithium‐Magnesium Separation with DFT Insights

Advanced Functional Materials, EarlyView.
We fabricated a biomimetic dendrimer‐modified thin‐film nanocomposite membrane with a coordination‐assisted ion‐selective interface. pH‐responsive polypeptide sites preferentially bind Mg2+ and promote Li+ permeation, as predicted by density functional theory calculations of metal‐ligand interactions.
