Mitochondria‐Targeted Multimodal Nanotherapeutics Suppress Oxidized mtDNA‐Driven Inflammation at the Source

Advanced Science, EarlyView.
Ox‐mtDNA fragments escaping from mitochondria drive robust inflammatory responses. A targeted nanoplatform simultaneously inhibits mitochondrial FEN1‐mediated mtDNA cleavage and scavenges ROS, preventing the generation of immunogenic Ox‐mtDNA fragments. The released SeNPs further promote autophagic clearance of cytosolic mtDNA. Consequently, cGAS‐STING,

Immune Checkpoint Inhibitor as a Fifth Component of Lipid Nanoparticles Enables Lymph Node‐Targeting and Augments mRNA Vaccine Efficacy

Advanced Science, EarlyView.
Here, a PDL1 inhibitor is employed as a fifth component to modify lipid nanoparticles (LNPs). PDL1 inhibitor‐loaded LNPs show enhanced lymph node targeting, resulting in greater lymph node expansion, immune cell infiltration, and improved mRNA vaccine efficacy. This fifth component LNP could be a novel platform for mRNA vaccines.

Fire‐Safe Hierarchical Solid Polymer Electrolytes Enabled by Dual‐Functional Microcapsules for Lithium Metal Batteries

Advanced Science, EarlyView.
Dual‐functional fire‐safe microcapsules are integrated into hierarchical solid polymer electrolytes to provide sequential protection against thermal abuse. The ammonium hydrogen phytate‐modified shell forms a protective char barrier, while the thermally triggered release of perfluoro(2‐methyl‐3‐pentanone) actively suppresses combustion, enabling safer ...

Synthesis of Ladder and Flexible Polysulfonimides Directly From Anionic Monomers: Investigating Structure–Property Convergence in Succinonitrile–Polymer Electrolyte Blends

Angewandte Chemie, EarlyView.
Direct synthesis of sulfonimide‐based polymers of intrinsic microporosity enables comparison with compositionally similar flexible analogs. Incorporation of a common pore‐filling transport medium drives these fundamentally different polymer architectures toward similar bulk conductivity and mechanical properties while revealing distinct microscopic ion‐

Triple‐Coupling Regulation Enables Dendrite‐Free Subzero Aqueous Zn‐Ion Batteries

Advanced Science, EarlyView.
A formamide‐ethanol deep eutectic electrolyte enables triple‐coupling regulation of solvation structure, interfacial chemistry, and crystallographic Zn deposition. The reconstructed Zn2+ solvation reduces water activity and suppresses side reactions, while a robust hybrid SEI stabilizes the interface.
