Cobalt Single‐Atom Nanozyme for Enhanced Intestinal Radioprotection and Tumor Radiosensitization via Bidirectional ROS Modulation

open access: yesAdvanced Science, EarlyView.
Orally administered, pH‐responsive Co‐SAN exerts dual functions: in the alkaline intestinal milieu, it scavenges reactive oxygen species (ROS) and suppresses the PI3K/AKT pathway and NETs formation, thus providing radioprotection; whereas in the acidic tumor microenvironment, it generates ROS and alleviates hypoxia, thereby enhancing radiosensitization.

Ti‐Doping Activates Adjacent Zr Sites in Bimetallic MOFs for Cooperative Phospholipid Removals in Human Biomonitoring

open access: yesAdvanced Science, EarlyView.
Ti‐doped Zr/Ti bimetallic MOFs activate neighboring Zr sites to selectively capture phospholipids from serum through cooperative interactions. In nontargeted screening, the material minimizes matrix interference, expands detectable feature coverage, and enables broad recovery of diverse chemical hazards, providing a powerful cleanup strategy for LC ...

A Phosphorylation‐Induced Micellization Switch in the Low‐Complexity Domain of TDP‐43

open access: yesAdvanced Science, EarlyView.
Phosphorylation of TAR DNA‐binding protein's 43 kDa (TDP‐43) low‐complexity domain by casein kinase 1 delta (CK1δ) acts as a molecular switch, redirecting its self‐assembly from macroscopic phase separation toward finite‐sized, spherical block‐copolymer micelles of ∼30 nm.

Synergizing Covalent‐Ionic Tri‐Site Coordination in P2‐type Na0.67Fe0.33Mn0.67O2 Induces Suppressed Layer‐Slipping and Stablized Lattice Oxygen for Sodium‐Ion Batteries at Wide Potential

open access: yesAdvanced Science, EarlyView.
Trans‐sublattice Cu/Mg/F three‐site coordination simultaneously stabilizes the oxygen framework and suppresses irreversible P2‐O2 phase transition and Jahn‐Teller distortion in Fe/Mn‐based layered cathodes. The optimized NFCMMOF enables highly reversible Fe3+/Fe4+ redox chemistry, accelerated Na+ transport, and robust interfacial kinetics, delivering ...
