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

open access: yesAdvanced 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.

A Multifunctional Potent Lewis Acid for In Situ Formation of Poly‐Dioxolane Electrolytes Toward High‐Performance Quasi‐Solid State Lithium Metal Batteries

open access: yesAdvanced Science, EarlyView.
Conventional polymer electrolytes based on poly‐dioxolane (PDOL) suffer from low ion mobility and unstable interfaces. Here, AlCl3‐initiated in situ polymerized gel PDOL electrolytes (AGPE) form a facile Li+ conduction path and hybrid SEI layers, thus enabling high Li+ conductivity and uniform Li deposition.

Dilute but Dense – Reversible Crosslinking Enables Water‐Rich (Bio)polymer Condensates

open access: yesAdvanced Science, EarlyView.
Reversible crosslinking between two types of (bio)polymers drives liquid–liquid phase separation even in good solvent. The arrangement of binding motifs controls condensate formation and density, and internal network structure. Simulations and theory reveal a closed‐loop coexistence phase diagram at very low monomer concentrations and re‐entrant ...

Photonic Time Crystals and Time‐Varying Electromagnetic Metamatter: A New Direction for Ultrafast Tunable Photonic and Microwave Materials and Devices

open access: yesAdvanced Science, EarlyView.
Photonic time crystals (PTCs) are systems in which electromagnetic parameters are modulated periodically in time, producing momentum bandgaps via temporal scattering rather than spatial Bragg processes. This review examines the theoretical frameworks, modeling, and computational tools for time‐varying media, and summarizes experimental demonstrations ...

Molecular Cluster‐Controlled Quasi‐Epitaxial CZTSSe/CdS Heterojunction Enables 12.3% Efficiency of Flexible Solar Cells

open access: yesAdvanced Science, EarlyView.
By controlling the synthesis of CdS molecular clusters, a quasi‐epitaxial heterojunction is directly constructed during chemical bath deposition, enabling flexible kesterite solar cells to achieve an efficiency of 12.3%. Abstract Flexible Cu2ZnSn(S,Se)4 (CZTSSe) solar cells have garnered significant attention in photovoltaics.
