Anchoring Redox Mediator on COFs for Efficient Solar to Hydrogen Conversion

Advanced Materials, EarlyView.
In this work, Fe ions are first fixed on COFs skeleton to construct a novel 2D Z‐scheme heterojunction (BWO/Fe/TP1C). The cycling of Fe3+/Fe2+ significantly improves the electron transfer rate. In addition, the construction of 2D Z‐scheme heterojunction not only promotes the separation of photogenerated carriers but also ensures its high redox activity.

Growth and mineralization of fetal mouse long bones under microgravity and daily 1 g gravity exposure

npj Microgravity
In a previous Space Shuttle/Spacelab experiment (STS-42), we observed direct responses of isolated fetal mouse long bones to near weightlessness. This paper aimed to verify those results and study the effects of daily 1×g exposure during microgravity on ...

Autonomous Implants

Advanced Materials, EarlyView.
An ideal implant should mimic native tissues such that it can integrate, sense, heal, and continue to function, i.e., be autonomous. Although early, there are good steps taken in this way, e.g., the development of stimuli‐responsive, self‐powering, self‐actuating, self‐healing, self‐regenerating, and self‐aware implants.

Unveiling the Electrolyte and Solid Electrolyte Interphase in Sodium Ion Batteries: Mechanisms, Progress, and Perspectives

Advanced Materials, EarlyView.
This review summarizes the recent advances in sodium‐ion battery electrolytes (including organic, aqueous, gel, ionic liquid, and solid‐state types) and their influence on the solid electrolyte interphase (SEI). It discusses SEI formation, aging, and optimization, as well as cases where no SEI forms, providing insights into the critical relationship ...

Promoting Electrochemical Reactions with Dual‐Atom Catalysts for High‐Rate Lithium–Sulfur Batteries

Advanced Materials, EarlyView.
A scalable strategy for synthesizing transition metal–bismuth atomic pairs on carbon nitride to accelerate sulfur redox reactions in lithium–sulfur batteries is presented. Nickel‐bismuth and cobatl‐bismuth catalysts improve rate performance by promoting direct electrochemical transitions and rapid Li2S nucleation, minimizing sulfur loss, and enhancing ...

Linear and Symmetric Artificial Synapses Driven by Hydrogen Bonding for Accurate and Reliable Neuromorphic Computing

Advanced Materials, EarlyView.
Hydrogen‐bond‐driven interface engineering enables highly linear and symmetric artificial synapses based on CsPbI3–PVA hybrids. This strategy suppresses trap states and guides directional ion migration, yielding stable optoelectronic plasticity. The devices achieve ultralow power operation and human‐like learning in neuromorphic networks, offering a ...

Lithium‐Charged Gold Nanoparticles: A New Powerful Tool for Lithium Delivery and Modulation of Glycogen Synthase Kinase 3 Activity

Advanced Materials, EarlyView.
This study introduces glutathione‐stabilized gold nanoparticles for targeted lithium delivery (LiG‐AuNPs), enabling the controlled modulation of Glycogen Synthase Kinase‐3 (GSK‐3β). These non‐toxic, 2‐nm particles release lithium intracellularly, effectively inhibiting GSK‐3β in the brain without significant plasma lithium alterations.
