Metal Ruthenium Complexes Treat Spinal Cord Injury By Alleviating Oxidative Stress Through Interaction With Antioxidant 1 Copper Chaperone Protein

Advanced Science
Oxidative stress is a major factor affecting spinal cord injury (SCI) prognosis. A ruthenium metal complex can aid in treating SCI by scavenging reactive oxygen species via a protein‐regulated mechanism to alleviate oxidative stress.

Single‐ and Dual‐Atom Configurations in Atomically Dispersed Catalysts for Lithium–Sulfur Batteries

Advanced Functional Materials, EarlyView.
Single‐atom and dual‐atom‐based atomically dispersed catalysts (ADCs) effectively address the shuttle effect and sluggish redox kinetics in Li–S batteries. With nearly 100% atomic utilization and tunable coordination environments, ADCs enhance LiPSs adsorption, lower conversion barriers, and accelerate sulfur redox reactions.

Rate‐Adaptive Site Transformation Catalyst for Parallel Water Dissociation and Hydrogen Adsorption in Alkaline Hydrogen Evolution

Advanced Functional Materials, EarlyView.
This work presents a rate‐adaptive site transformation strategy in Ag‑ethylenediamine intercalated Co9S8, which not only enables parallel water dissociation and H* adsorption, but also allows the catalyst to provide more active sites under high demand, removing a major bottleneck. The catalyst achieves a record current density of 4.2 A cm−2@2.0 V, with

Aqueous Two‐Phase Bioinks for Discrete Packing and Compartmentalization of 3D Bioprinted Cells

Advanced Healthcare Materials, EarlyView.
Aqueous two‐phase systems (ATPS) enable the formation of biomimetic interfaces crucial for tissue engineering. However, clinical translation remains limited by the challenge of precisely controlling cellular compartmentalization. Here, we developed ATPS biomaterial inks for 3D bioprinting allowing tuneable droplet formation via NaCl modulation.
