Two dimensional Conjugated Metal–Organic Frameworks with Multiple Redox‐Active Sites towards High‐Performance Sodium‐Ion Battery

open access: yesAdvanced Science, EarlyView.
Three isoreticular Two dimensional (2D) conjugated metal–organic framework (2D c‐MOF) analogs with different redox‐active centers are synthesized as cathode materials for high‐performance sodium‐ion batteries. Notably, the [CuO4] and TTPQ (integrating both quinone and pyrazine structures) units within Cu‐TTPQ, serving as multiple redox‐active sites ...

Self‐Powered UV Dual‐Band Photodetector Based on Cs3BiCl6/GaN Heterojunction for Logical Operation and Encrypted Photo‐Communication

open access: yesAdvanced Science, EarlyView.
Utilizing the special dual‐band absorption characteristics of Cs3BiCl6 and its strong surface‐charge recombination behavior, a self‐powered UV dual‐band photodetector based on Cs3BiCl6/GaN heterojunction is developed. As a result, the photodetector exhibits excellent specific detectivity of 1.23 × 1012 Jones and ultrafast response speed of τr/τf = 28 ...

Laser‐Induced Coal‐Based Porous Graphene as Anode Toward Advanced Lithium‐Ion Battery

open access: yesAdvanced Science, EarlyView.
A one‐step laser‐induced strategy is reported to prepare porous graphene by utilizing bituminous coal as a precursor (LIG‐B). Laser irradiation transforms coal into graphene, with small molecules from the polymer separating, recombining in gas and forming 3D porous graphene upon quick gas release.

Wireless In Situ Catalytic Electron Signaling‐Mediated Transcriptomic Reprogramming for Neuron Regeneration via Adaptable Antennas

open access: yesAdvanced Science, EarlyView.
A wireless‐charging sustained oxygen release from conductive microgels (SOCO) served as an antenna and an on‐demand O2 release for nerve regeneration is developed. Introducing “electromagnetic messenger”, using external alternating magnetic field (AMF) to enhance catalytic oxygen release and electrical stimulation to promote the reconstruction of blood
