Achieving Fast Charging and Superior Cycling Stability Single‐Crystal Ni‐Rich Cathodes by Ultrafast Aqueous Washing

Advanced Science, EarlyView.
Prolonged water washing severely damages the surface layered structure of single‐crystal Ni‐rich cathodes, forming a thick rock‐salt barrier. In contrast, our 3‐min ultrafast washing removes residual lithium while confining surface reconstruction to an ultrathin 2–4 nm layer, thereby unlocking excellent fast‐charging and cycling stability.

Electric Field Modulation of Interlayer Coupling via Piezostrain in a Synthetic Antiferromagnet

Advanced Science, EarlyView.
Controlling the interlayer exchange coupling (IEC) in synthetic antiferromagnets (SAFs) using an electric field is a promising route toward energy‐efficient spintronic devices. In this study, electric field induced‐strain modulation of IEC in Co/Ru/Co SAF/PMN‐PT is demonstrated.

Thermal‐Stable and High‐Performance Organic Nonlinear Optical Chromophores for Advanced Electro‐Optic Modulators

Advanced Science, EarlyView.
To address the challenge of high electro‐optic (EO) activity and thermal stability, four chromophores (BHG1–BHG4) are designed. These incorporate steric hindrance groups into the aniline donor, significantly raising their glass transition temperatures and enhancing alignment stability. The neat BHG2 film achieves an exceptional EO coefficient of 304 pm

Hierarchical Strain‐Modified Medium‐Entropy Carbide Ceramics Exhibit Exceptional Ablation Resistance up to 2400°C

Advanced Science, EarlyView.
A novel strategy is developed by doping reduced graphene oxide (rGO) into a (HfZrTi)C medium‐entropy ceramic. This induces a hierarchical strain modification mechanism, synergistically inhibiting crack propagation at the microscale and dissipating stress at the mesoscale.

Enhanced Oxygen Redox Activity and Structure Stability of P2‐Type Manganese‐Based Cathodes Through Medium‐Entropy Strategy

Advanced Science, EarlyView.
A medium‐entropy strategy guided by ionic potential is applied to weaken TM─O bonds and suppress Jahn–Teller distortion in P2‐type cathodes, thereby enhancing the oxygen redox activity and structure stability. A medium‐entropy oxide, Na0.8Li0.1Ni0.1Cu0.1Ti0.1Mn0.6O2, demonstrates a high reversible capacity of 223.7 mAh g−1 and an energy density of 616 ...
