Methylation‐Induced Permanent Charge Polarization in Covalent Organic Frameworks for Visible Light‐Driven Water Decontamination and Disinfection

open access: yesAdvanced Science, EarlyView.
A targeted in situ methylation strategy is developed to engineer cationic centers in a quinoline‐linked COF (NQ‐COFS1‐Me), creating a strong built‐in electric field, which effectively suppresses excitonic effects and promotes charge separation. The optimized material demonstrates powerful photocatalytic ROS generation for rapid bacterial inactivation ...

Engineered Interpenetrating MXene Networks in Aramid Layered Films for Antioxidant and Broadband Electromagnetic Interference Shielding

open access: yesAdvanced Science, EarlyView.
This study introduces an innovative interpenetrating layered structure, comprising alternating aramid nanofiber (ANF) layers and MXene layers, fabricated through a directional freeze–thaw intercalation–gel‐film formation strategy. Unlike traditional homogeneous layered films, this unique layered structure features mutually embedded conductive and ...

Structural and Mechanical Dynamics of Polymer Membranes Across Multilength Scales

open access: yesAdvanced Science, EarlyView.
Distinct surface‐to‐bulk mechanical contrasts in polymer membranes were unveiled, highlighting the need to probe both regions to fully capture their functional behavior. By integrating in situ SAXS–WAXS with AFM‐based nanomechanics, nanodomain‐level heterogeneity and real‐time structural transformations induced by thermal and mechanical stimuli were ...
