Activation‐Induced Turbostratic Ordering in pDCPD‐Derived Hard Carbon Enables Stable Carbonate‐Based Sodium‐Ion Storage

open access: yesAdvanced Science, EarlyView.
Hard carbon derived from templated poly(dicyclopentadiene) as anode for sodium–ion batteries was engineered through carbonization and second‐step CO2${\rm CO}_2$ activation. High‐temperature carbonization and activation increased local ordering while reducing defects without inducing structural fracture.

Lithium‐Doped Hydroxyapatite Nanowires Rejuvenate Senescent Macrophages Via the Lysosome‐Dependent Ferroptosis Axis to Promote Aged Bone Regeneration

open access: yesAdvanced Science, EarlyView.
Li‐nHAP+GelMA promotes mandibular bone regeneration in aged mice by remodeling the senescent immune microenvironment. Local delivery of Li‐nHAP restores lysosomal homeostasis in senescent macrophages, reduces intracellular labile Fe2+ accumulation, ROS production, and lipid peroxidation, thereby suppressing macrophage ferroptosis and senescence ...

Injectable Peptide‐Based Functional Amyloid Hydrogels as Tunable Depots for Sustained Drug Delivery

open access: yesAdvanced Science, EarlyView.
An injectable and tunable peptide‐based functional amyloid hydrogel provides sustained insulin release while preserving insulin stability and bioactivity. The hydrogel enables prolonged glycemic regulation in vivo, exhibits excellent biocompatibility, and shows no detectable IAPP and α‐Syn heterologous cross‐seeding, highlighting its potential as a ...

Oxygen‐Scavenging‐Driven Interlayer Engineering for Balancing Linearity and Retention in IGZO Synaptic Memristors

open access: yesAdvanced Electronic Materials, EarlyView.
Oxygen‐scavenging‐induced self‐formed interlayers regulate Schottky‐barrier modulation in IGZO memristors, producing a fundamental trade‐off between synaptic update linearity and retention. A preserved AlOx interlayer moderates voltage distribution and enables gradual, nearly linear conductance updates, whereas a soft‐broken SiO2 interlayer provides a ...

MoS2 Memristors Made by Liquid–Liquid Interface Assembly and Ultraprecise Metal Printing

open access: yesAdvanced Electronic Materials, EarlyView.
A cleanroom‐free, fully additive fabrication route combines ultraprecise printed silver electrodes with Langmuir–Schaefer‐deposited bilayer MoS2 to realize ultralow‐power resistive switching devices. The resulting microscale memories exhibit low operating voltages, a large memory window, stable retention and endurance, demonstrating a scalable and cost‐

Controllable Superconductivity in Suspended NbSe2

open access: yesAdvanced Electronic Materials, EarlyView.
Suspended NbSe2${\rm NbSe}_2$ provides two complementary routes for controlling superconducting transport. Gate‐driven deformation strains the suspended crystal and tunes its critical temperature and current. Weak thermal anchoring enhances thermal feedback, contributing to multistep hysteresis and negative differential resistance.
