Stoichiometry‐Programmed MXenes via Precursor Engineering for High‐Performance EMI Shielding and Energy Storage

Advanced Materials, EarlyView.
Precursor carbon stoichiometry programs internal strain and oxygen substitution in Ti3AlCxO2‐x, deterministically switching Ti3CxO2‐xTz MXenes between highly aligned 2D nanosheets and spontaneous 1D nanoscrolls. This synthesis‐stage architecture control enables ultrathin X/W‐band EMI shielding with outstanding mass‐normalized performance and bending ...

Hybridized Charge‐Transfer Window within a Fully Conjugated Multi‐Resonance Thermally Activated Delayed Fluorescence Framework for Ultrafast Reverse Intersystem Crossing and High‐Efficiency in Deep‐Blue Organic Light‐Emitting Diodes

Advanced Materials, EarlyView.
A hybridized charge‐transfer window combining short‐range and long‐range charge transfer is realized within a fully conjugated multi‐resonance thermally activated delayed fluorescence framework. The resulting excited‐state hybridization minimizes the singlet–triplet energy gap (0.04 eV) and enables ultrafast reverse intersystem crossing (krISC = 2.1 ...

Hydro‐Torsional Compaction for Scalable Production of Aramid Nanofiber Threads with Densely Assembled Double‐Helical Nanostructures

Advanced Materials, EarlyView.
This paper introduces a scalable strategy for producing hierarchically aligned PBDT threads through wet‐spinning, controlled drawing, and post‐spinning twisting. Ionic crosslinking reinforces structural stability, whereas alignment and twisting optimize mechanical performance.

Undercoordinated Molybdenum Catalysts Enable Ultrafast Quasi‐Solid Sulfur Chemistry in Sodium‐Sulfur Batteries

Advanced Materials, EarlyView.
An unsaturated coordination chemistry strategy activates a quasi‐solid‐state redox pathway by strengthening NaPSs adsorption and accelerating redox conversion kinetics, thereby overcoming the kinetic bottlenecks that limit high‐rate performance. In situ transmission electron microscopy, combined with newly developed Na‐ion diffusion descriptors ...
