Two‐Step Thermal Upcycling of Flexible Printed Circuit Board Waste Into Metallic Copper Nanoparticles: Synthesis and Characterization

open access: yesAdvanced Materials Technologies, EarlyView.
A two‐step thermal upcycling process converts flexible printed circuit board waste into high‐purity copper nanoparticles using polymer degradation and arc discharge. The synthesized nanoparticles exhibit controlled morphology and high metal purity.

Beyond Traditional Phenolics: Disulfide Bonds for Performance Enhancement of Aerospace Ablation‐Resistant Materials from Processing to Recycling

open access: yesAdvanced Science, EarlyView.
The dynamic disulfide bonds facilitated the development of high‐performance aerospace ablation‐resistant materials. At moderate temperature, the dissociation and recombination of disulfide bonds ensured excellent processability, mechanical properties, and recycling ability of phenolic resin; at high temperature, cleavage of disulfide bonds produced ...

Heat‐Suppressing Projection Two‐Photon Lithography Enables High‐Throughput Sub‐Micrometer Manufacturing of Biopolymer Hydrogels for Tissue Engineering

open access: yesAdvanced Science, EarlyView.
The iLEAP technique integrates high‐throughput two‐photon lithography with extrusion printing, bridging sub‐micrometer precision and macroscopic scaffold fabrication. By employing a low‐exothermic photoinitiator, it mitigates thermal damage to biopolymers and preserves bioactivity.

Multi‐Scale Bionic Structure Constructs Biomass Flame‐Retardant Thermal Insulation Foam Material

open access: yesAdvanced Science, EarlyView.
Inspired by mussel adhesion and hierarchical brick‐and‐mortar architectures, a cellulose‐based biomimetic foam is constructed by anchoring bentonite nanosheets onto a polydopamine‐decorated cellulose nanofiber network. The resulting foam combines low thermal conductivity with intrinsic flame retardancy and full biodegradability, presenting a ...

RNA Promotes Synapsin Condensates That Organize Synaptic Vesicles in Live Neurons and Enable Localized Translation in Reconstituted System

open access: yesAdvanced Science, EarlyView.
Condensates at synapses organize synaptic vesicles (SVs) and are crucial for efficient neurotransmitter release, yet how RNA contributes to this mesoscale architecture remains poorly understood. Here we uncover that RNA modulates synapsin–driven condensates.
