Linker‐Locking Strategy for the Rigidification of Flexible Metal–Organic Framework: Structural Stabilization and Controlled ESIPT for H2O/D2O Sensing

Advanced Science, EarlyView.
A linker‐locking strategy rigidifies the flexible metal–organic framework (MOF) MIL‐53‐(OH)2 via the cooperative encapsulation of ligands and structural water. This network significantly enhances the framework's aqueous stability. Crucially, rigidification suppresses enol emission to yield a single keto tautomer state with an extended lifetime ...

High‐Density Type I Collagen Promotes IFN‐γ+ CD8+ T Cell Exhaustion via SAT1‐ASS1‐Mediated Glutamine Accumulation and Ferroptosis in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
High‐density type I collagen promotes glutamine (Gln) accumulation–related ferroptosis of TNBC cells via the spermidine/spermine N1‐acetyltransferase 1 (SAT1)‐ argininosuccinate synthase (ASS1) signaling pathway, thus depriving immune cells of Gln supply and inducing IFN‐γ+ CD8+ T cell exhaustion in the TME.

Solvent‐Free Synthesis of Ultrabright Carbon Dots With Near‐Unity Quantum Yield for High‐Performance Light‐Emitting Diodes

Advanced Science, EarlyView.
A rational, solvent‐free synthesis utilizing 2,6‐diaminonaphthalene produces ultrabright green‐emissive carbon dots. Regulated by a self‐limiting oxidative capping mechanism, excitons undergo ultrafast intra‐particle funneling from the nitrogen‐doped carbon core to emissive surface traps.

In Situ Bioorthogonal Synthesis of PROTACs via Dual‐Responsive Cleavage for Synergistic Photo‐Immunotherapy

Advanced Science, EarlyView.
A bioactive self‐delivering SNAP‐TAC platform responds to tumor‐associated cathepsin B and glutathione, enabling in situ bioorthogonal synthesis of a BRD4‐degrading proteolysis‐targeting chimera within the tumor microenvironment. The resulting BRD4 degradation and PD‐L1 downregulation synergize with photodynamic therapy‐induced immunogenic cell death ...

cis‐Carboxylate Enhancement of Mn(III)‐OH Hydrogen Atom Abstraction through PCET Thermodynamics

Advanced Science, EarlyView.
ABSTRACT Manganese(III)‐hydroxo intermediates are proposed as key hydrogen atom abstraction (HAA) species in manganese‐dependent enzymes, yet how first‐sphere carboxylate ligands control their proton‐coupled electron transfer (PCET) thermodynamics remains poorly understood.

Osmium Nanoparticle Anchoring on CoFe Layered Double Hydroxides Enables High‐Valent Species Stabilization and Efficient Seawater Oxygen Evolution

Advanced Science, EarlyView.
Osmium nanoparticles anchored on CoFe layered double hydroxide (Os/CoFe LDH) stabilize high‐valent Co/Fe species and modulate the interfacial water configuration via surface engineering. This work presents a facile surface engineering strategy for constructing efficient and durable OER electrocatalysts for alkaline seawater, and expands the ...
