High‐Performance Recycling Biobased Photopolymers for 3D Printing

Advanced Science, EarlyView.
By using biobased phenols like eugenol, novel biobased photopolymers containing dissociative phenol‐carbamate bonds are designed for 3D printing. Meanwhile, a “mixed‐monomer assisted recycling” strategy is proposed to recycle the materials. The resulting materials not only achieve high‐performance and excellent chemical recyclability simultaneously ...

Enzymatic Basis for the Oxidative Branch of Aromatic Amino Acid Fermentation Leading to p‐cresol Formation

Advanced Science, EarlyView.
In anaerobic bacteria, tyrosine serves as an electron donor in the oxidative Stickland fermentation branch, generating p‐hydroxyphenylacetate, ATP and reduced ferredoxin for decarboxylation into p‐cresol. ABSTRACT The phenolic metabolite p‐cresol is a byproduct of tyrosine fermentation by certain strictly anaerobic bacteria, including the human gut ...

Nanocurvature‐Activated Dipolar Polarization in M–N4 Single‐Atom Sites for High‐Performance Electromagnetic Wave Absorption

Advanced Science, EarlyView.
Increasing nanocurvature effectively enriches the local electron density of the M–N4 motif, which facilitates electron transfer from the metal center to nitrogen atoms. This electronic behavior intensifies the localization and asymmetric distribution of charge, thereby significantly amplifying the dipole moment and polarizability.

Retina‐Inspired Bi‐Based Terahertz Photonic Neuromorphic Devices

Advanced Science, EarlyView.
Combined with effective band alignment and substrate engineering, bismuth materials are introduced to form terahertz photonic bio‐inspired devices with picosecond short‐term plasticity to enable multi‐scene visual perception. Thus obtained hardware through the terahertz optical neural network (THz‐ONN) demonstrates high recognition accuracy, providing ...
