Optimized Antimony‐Doped Tin Oxide Thin Films With Enhanced Electrical Properties for Low‐Emissivity Architectural Coatings

Advanced Science, EarlyView.
Antimony‐doped tin oxide (ATO) thin films were deposited by aerosol‐assisted chemical vapor deposition (AACVD) and systematically investigated to establish correlations between Sb doping level, structural properties and optoelectronic performance. Optimized films exhibited low sheet resistance, high carrier concentrations, and high visible transparency

Dynamique spatio-temporelle de la mangrove du Parc National du Delta du Saloum (PNDS), Sénégal

Revue Ecosystèmes et Paysages
La mangrove du Saloum joue un rôle très important sur les plans socio-économique et écologique. Toutefois, elle subit une dégradation due aux effets conjugués de plusieurs paramètres qui, jusque-là, n’ont pas fait l’objet d’études.

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

Advanced 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 ...

Machine Learning–Guided Surface Strain Engineering in Connected Platinum–Nickel Nanoparticle Catalysts for Advanced Oxygen Reduction Performance

Advanced Science, EarlyView.
Machine learning‐guided strain engineering enables highly active, durable, support‐free Pt–Ni nanonetwork catalysts for the oxygen reduction reaction. Analysis of a Pt‐based catalyst dataset identifies surface compressive strain as an effective descriptor associated with enhanced activity and provided practical design guidelines.

AI Designed Conformation Locking Peptides Target STING to Restore Diabetic Wound Healing

Advanced Science, EarlyView.
A generative AI pipeline identifies SCP‐1, a conformation‐locking peptide that stabilizes inactive STING. Incorporated into a dual‐responsive hydrogel for localized, MMP‐9‐triggered release, SCP‐1 suppresses inflammation, promotes reparative macrophage polarization, and accelerates diabetic wound healing.

Epitaxial Oxide Interfaces Create Poison‐Resistant CuO Sites for Environmental Catalysis

Angewandte Chemie, EarlyView.
An epitaxially stabilized CuO overlayer on Ti1−xInxO2 creates electron‐poor, high‐symmetry Cu–O sites that activate interfacial lattice‐oxygen redox. This interface promotes NOx reduction through an Eley–Rideal pathway, diverts sulfate formation, and sustains CH3SH deep oxidation via a Mars–van Krevelen cycle, offering a route to poison‐resistant ...

High‐Entropy Engineering and External Magnetic Field Modulation Synergistically Enhance the H2S Sensing Performance of Rare‐Earth Perovskite Ferrites

Advanced Science, EarlyView.
A novel high‐entropy perovskite oxide, (Gd0.2Tb0.2Dy0.2Ho0.2Er0.2)FeO3, was successfully synthesized for advanced hydrogen sulfide gas detection. By synergistically coupling high‐entropy‐induced local lattice distortion with weak magnetic field modulation, the tailored material generates abundant active sites. This innovative dual strategy dramatically

Light‐Absorbing‐Layer‐Free Flash Lamp Annealing for High‐Throughput Fabrication of All‐Solution‐Processed Oxide Electronics

Advanced Science, EarlyView.
A flash lamp annealing strategy using a mullite chuck enables rapid conversion of sol–gels to metal oxides on silicon and ultra‐thin glass without extra light‐absorbing layers. Direct light absorption initiates the transformation, and the low thermal conductivity of mullite promotes heat accumulation.
