Atomic Layered ZnO Between Cu Nanoparticles and a PVP Polymer Layer Enable Exceptional Selectivity and Stability in Electrocatalytic CO2 Reduction to C2H4

Advanced Science, EarlyView.
Collaboration between Cu, ZnO, and PVP facilitates the electrochemical reduction of CO2. Abstract This study employs a chemically controlled strategy to construct a few‐atomic‐layer ZnO structure integrated with polyvinylpyrrolidone (PVP) and nanoscale metallic copper on active carbon.

Bacteria Optimize Tumble Bias to Strategically Navigate Surface Constraints

Advanced Science, EarlyView.
The study investigates how Escherichia coli optimizes tumble bias (TB) to navigate surface constraints effectively. Using single‐cell tracking and modeling, it reveals that bacterial surface residence time decreases with increasing TB, stabilizing near the wild‐type mean TB (≈0.25), where surface diffusivity peaks.

Probing the Challenge of P‐Type Semiconductors in Long‐Chain VOC Detection: 3D Micro‐Flower Zinc Cobaltate Heterojunction Sensors

Advanced Science, EarlyView.
Fe@WO3/ZnCo2O4 n‐p heterojunction sensor exhibits excellent room‐temperature sensing toward tetradecane, with a low detection limit of 78.4 ppb and short recovery time. The good performance is attributed to synergistic effects from heterojunctions, heteroatom doping, oxygen vacancies, high‐energy facets, and theoretical validations.

Cartilage‐Penetrating Framework Nucleic Acid Nanoparticles Ameliorate Osteoarthritis by Promoting Drug Delivery and Chondrocyte Uptake

Advanced Science, EarlyView.
Based on the poor cartilage penetration of tFNA, a novel tFNA‐2WL with excellent cartilage permeability and perfect chondrocyte endocytosis properties is designed and fabricated. As a result, tFNA‐2WL has a nearly seven‐fold increase in the penetration depth into the cartilage, with the same excellent cell entry properties as tFNA.

Cu‒S Covalent Bonds Enable the Anchoring of Single‐atom Cu on Layered MoS2 for Highly Selective and Active Photothermal Catalytic Conversion of CO2−H2O to Ethanol

Advanced Science, EarlyView.
Cu5%‐MoS2 with dual Cu and Mo active sites enables efficient photothermal synergistic catalysis of the CO2–H2O system for ethanol production. The catalyst achieves a high ethanol yield of 3.1 mmol·g−1·h−1 with 88.35% selectivity, showcasing exceptional performance and selectivity under mild conditions. Abstract The catalytic conversion of CO2 into high‐

Chirality Regulates Stem Cell Fate and Promotes Corneal Epithelial Regeneration via Manipulating Notch Pathway

Advanced Science, EarlyView.
Chirality governs the limbal epithelial stem cell fate. Right‐handed chirality enhances cell proliferation and differentiation, while left‐handed chirality partially maintains cell stemness. By activating the Notch pathway, 3D right‐handed chiral hydrogel offers a drug‐free and cell‐free strategy for effective corneal regeneration.
