Pre‐Refinement Prediction of Dopant Site Occupancy in M‐Type Hexaferrites via Hierarchical and Uncertainty‐Aware Machine‐Learning

Advanced Science, EarlyView.
Refined data are extracted from CIF files to construct a hierarchical machine‐learning framework integrating sublattice classification, Fe‐site occupancy prediction, and reliability assessment. External validation yields 96% accuracy for sublattice classification and a macro mean absolute error of 0.0584 for Fe‐site prediction.

Overcoming the *H‐NOx Coupling Bottleneck via Palladium‐Enabled Relay Catalysis on CuCo2O4 Toward Ampere‐Level Nitrate‐to‐Ammonia

Advanced Science, EarlyView.
Pd‐doped hollow spiny CuCo2O4 microspheres deliver ampere‐level electrocatalytic nitrate to ammonia. Cu and Co sites undergo relay catalysis for sequential nitrate reduction, while Pd accelerates water dissociation to supply abundant active hydrogen (*H).

Electrocatalytic Urea Synthesis From CO2 and N2/NO3−: Bridging Catalyst Activity, C–N Coupling Kinetics, and Industrial Applicability

Advanced Science, EarlyView.
This review compares NO3− + CO2 and N2 + CO2 electrocatalytic urea synthesis in feedstock properties, catalyst design, C–N coupling mechanisms, performance optimization, and engineering applicability. The two systems correspond to a near‐term deployable route and a long‐term green synthesis goal, respectively.

Stabilizing Oxygen Redox via Li Dopants Into P2‐Type Cathodes for High‐Voltage Sodium‐Ion Batteries

Advanced Science, EarlyView.
Regulating anionic redox of layered cathodes provides the promises as performance promotor for sodium ion batteries. In this work, Li doping strategy has been developed to stabilize oxygen redox in the voltage window from 4.1 to 4.3 V. The underlying mechanism has been investigated through integrating a variety of characterizations.

Bacterial Geosmin Biosynthesis is Compartmentalized Inside a Two‐Component Protein Shell

Advanced Science, EarlyView.
This study reports the discovery that geosmin biosynthesis is compartmentalized inside a two‐component protein shell in many bacteria. Sequestration of geosmin synthase inside a Family 2B encapsulin nanocompartment improves geosmin yield and increases enzyme stability as compared to the free enzyme.
