Synergistic Hydrogen‐Bonding and Covalent Crosslinking in Polybenzimidazole Membranes for Wide‐Temperature Anhydrous Fuel Cells

open access: yesAdvanced Science, EarlyView.
A dual‐network architecture combining a thermally reinforced hydrogen‐bonding matrix with an amine‐anhydride covalent framework was constructed in Tröger's Base (TB)‐functionalized polybenzimidazoles. This design yielded the TBAm‐PBI‐TB membrane with high acid uptake (469.5%), anhydrous conductivity (264.7 mS cm−1), and robust stability.

Transparent Photothermal Slippery Surface Based on Monolayer Self‐Assembled MXene Film for Anti‐Fogging and De‐Icing

open access: yesAdvanced Science, EarlyView.
The ultrathin (2.5 nm) MXene film self‐assembled at liquid interfaces breaks the trade‐off between transparency (82.5 %) and photothermal conversion effect (DT∼25.1°C ± 2.9 °C) under 100 mW cm−2. After encapsulated by a slippery surface with low adhesion, this transparent film can be applied in smart windows, eyewear, and optical sensors to autonomous ...

Surface‐Bound Superoxide Radical‐Mediated Photo‐Fenton Mineralization of Ciprofloxacin on Fe‐Sillenite Nanosheets

open access: yesAdvanced Science, EarlyView.
This study systematically compares the degradation efficiency of CIP in a H2O2‐alone system and a novel Bi12FeO20‐H2O2 photo‐Fenton system. It reveals for the first time the presence of a quinone‐imine intermediate in the H2O2‐alone system, which exhibits toxicity comparable to CIP.

Absorption‐Dominant Electromagnetic Interference Shielding of Ti3C2Tx MXene‐Coated and Fe3O4‐Integrated TPMS Composites with Coupled Gradient Conductivity and Size‐Graded Structure

open access: yesAdvanced Science, EarlyView.
A functionally driven variable‐cell size and gradient‐conductive coated TPMS structure was developed. Accordingly, stepwise longitudinal gradient impedance was realized, achieving absorption‐dominant EMI shielding (absorptivity≈0.85) with an EMI SET of ≈ 59 dB, for 10 mm‐thick composites. Further increasing the thickness of composites to 20 mm achieved

Review: Insight on Porous Carbon Positive Electrode for Sodium‐Ion Capacitors: Interplay Between Synthesis, Properties, and Performance

open access: yesAdvanced Science, EarlyView.
Sodium ion capacitor (SIC) is currently constrained by the low discharge capacity of commercial activated carbon as positive electrode material. This review provides a holistic summary of research efforts on alternative porous carbon materials for SIC. Image created by the authors with www.biorender.com.
