ROS‐Responsive Nanoparticle Delivery of Dexmedetomidine Protects the Gut Vascular Barrier After Intestinal Ischemia/Reperfusion via the HDAC‐H3K27ac‐TCF4 Axis

Advanced Science, EarlyView.
A low dose of dexmedetomidine, delivered by ROS‐responsive nanoparticles, preferentially accumulates in the ischemic intestine and restores gut vascular barrier integrity after ischemia/reperfusion injury. This nanoparticle‐based strategy prevents bacterial translocation and liver damage without cardiorespiratory side effects, working through HDAC ...

Permanent Oxidative Dipole Engineering in Quinoline COFs for Boosting Exciton Dissociation and Oxygen Activation in H2O2 Photosynthesis

Advanced Science, EarlyView.
Permanent oxidative dipole (POD) engineering overcomes the electronic uniformity of quinoline‐linked COFs. By enhancing the dipole moment to 2.08 D and lowering exciton binding energy to 20.3 meV, it constructs a robust built‐in electric field and spatially decoupled redox centers. This bypasses inherent kinetic bottlenecks, achieving a 4569 µmol g−1 h−

Photochemical Oxygen-Atom-Transfer Reactivity of Platinum(II) Peroxycarbonates. [PDF]

Angew Chem Int Ed Engl
The coordination chemistry of metal–peroxycarbonate complexes (M(CO4)) remains poorly understood, with no reported studies of the photochemical reactivity of M(CO4) complexes. The platinum(II) peroxycarbonate complexes Pt(PPh3)2(CO4) and Pt(dppe)(CO4) (dppe = 1,2‐bis(diphenylphosphino)ethane) have been structurally characterized and are shown to ...

Nickelferrite on Pnictogen Functionalized Carbon Nanohorns. Bifunctional ORR and OER Catalysts in Rechargeable Zinc‐Air Batteries

Advanced Science, EarlyView.
A systematic study on the performance of N,P‐doped NiFe2O4@CNH bi‐functional hybrid electrocatalysts for rechargeable zinc‐air batteries is presented. The importance of P, N‐doping and the intimate tethering of nickel‐ferrite nanocubes on the carbon nano‐horn (CNH) surface which are well dispersed on the surface of N,P doped CNHs.

Spatial Au+ Mapping Reveals a Self‐Amplifying Anti‐Tumor Immunity Loop Driven by Au(I) Complexes

Advanced Science, EarlyView.
The first report of spatial Au+ mapping of a representative gold complex (Au9). Macrophages, DCs, and tumor cells ranked as the top three in Au+ enrichment after Au9 treatment. Interestingly, Au9 treatment could induce ferroptosis and suppress cellular cholesterol, further eliciting a self‐amplifying anti‐tumor immunity loop.

H-1 NMR, spectroscopic and molecular modeling studies on paramagnetic lanthanide(III)-quercetin complexes [PDF]

, 2008
Nine coordinated [Ln(quercetin)(3)]nH(2)O complexes were synthesized in non-aqueous solution (where, n = 0 for Pr, Sm, Gd, Tb, Dy and Ho; n = 3, for La and Nd). The complexes were characterized by elemental analysis, molar conductance, UV-vis spectra, IR

High‐Performance Bio‐Based Epoxy Vitrimers and Composites: Synergizing Robustness and Reprocessability via Fractional Free Volume Regulation

Advanced Science, EarlyView.
In this work, two bio‐based epoxy monomers were designed to tune the dynamic network of a rigid–flexible hybrid epoxy through free‐volume control, achieving a synergy among high free volume, high cross‐linking density, and segmental mobility while balancing strength and toughness.

Pt‐Regulated Dynamic Cu(0) Regeneration in CuPt Alloy Enables High‐Efficiency Self‐Driven Formaldehyde Fuel Cells for Potassium Formate Production

Advanced Science, EarlyView.
In this work, a Cu30PtX/CF anode material was synthesized to effectively catalyze the electrocatalytic formaldehyde oxidation, and thereby assembled a fuel cell that offered a high open‐circuit potential of 0.94 V and a power density of 34.3 mW cm−2. This work realizes the co‐generation of electrical energy and high‐value‐added chemicals with nearly ...
