The continuous evolution of the cold structure from localized origin to global collapse during the thermal quench on the J-TEXT tokamak

Nuclear Fusion
Understanding the origin of the tokamak thermal quench (TQ) remains a critical unresolved issue, particularly the causal link between initial localized temperature collapse and the final core energy collapse.

Broadband Silicon‐On‐Glass Reflective Dielectric Metasurface for THz Beam Steering in 6G Wireless Networks

Advanced Functional Materials, EarlyView.
A CMOS‐compatible, all‐dielectric Silicon‐on‐Glass reflective metasurface enables low–loss terahertz wavefront control for future 6G wireless communication. Mie‐resonant silicon pillars provide full phase coverage near 500 GHz, achieving experimentally validated single‐, dual‐, and five‐beam steering with sub‐1.5° angular error and less than 3 dB ...

Spatially Regulated Lithium Plating via Li2O‐Rich Interphase Enables Durable Fast‐Charging Hybrid Lithium Batteries

Advanced Functional Materials, EarlyView.
A Li2O‐rich solid electrolyte interphase (SEI) is engineered on graphite through a propylene carbonate‐based electrolyte to spatially regulate Li plating. The homogeneous interphase lowers Li nucleation barriers, promotes conformal Li deposition around graphite particles, and suppresses dendritic accumulation, enabling durable hybrid Li‐ion/Li‐metal ...

Thermal transport induced by stochastic magnetic fields and turbulence during the thermal quench in tokamak plasmas

Nuclear Fusion
The timescale of thermal quench (TQ) remains a long-lasting issue in tokamak plasmas, which has not been fully understood yet. In this work, based on our previous thermal diffusion model and further considering the scattering caused by the electrostatic ...

Dynamically Actuated Reconfigurable Topographical Surface Enables Active Control of Implant‐Associated Infections

Advanced Functional Materials, EarlyView.
A dynamically actuated reconfigurable topographical surface (DARTS) integrates contact‐mediated bactericidal nanotopography with programmable mechanical actuation to actively disrupt bacterial biofilms. Dynamic surface reconfiguration enhances bacterial killing and suppresses implant‐associated infections in vivo, providing a new strategy for active ...

Direct Integration of Conductive, Emissive Perovskite Nanocrystals Into Efficient Light‐Emitting Diodes Without Post‐Synthetic Ligand Exchange

Advanced Functional Materials, EarlyView.
We demonstrate the direct integration of CsPbBr3 perovskite nanocrystals (PNCs) into optoelectronic devices without post‐synthetic ligand exchange. This is achieved by synthesizing PNCs stabilized by strong‐binding‐energy oleylammonium–bromide pairs instead of oleate ligands. The resultant low ligand density and minimized surface defects enhance charge

Exchange‐Coupled Two‐Dimensional MOFs

Advanced Functional Materials, EarlyView.
Graphene mediates ferromagnetic coupling between two‐dimensional metal‐organic frameworks and cobalt. Fe‐tetracyanobenzene develops a remanent magnetic response whose orientation follows the cobalt magnetization direction and persists up to room temperature, whereas Ni‐TCNB remains only field‐polarized.

Physically constrained data-driven inversion of 2D fast-ion velocity distributions from single view CTS spectra

Nuclear Fusion
Reconstructing fast-ion velocity distributions from collective Thomson scattering (CTS) spectra is an ill-posed inverse problem due to the spectral nonlinearity, strong parameter coupling and measurement noise.
