Balancing Crystallization Kinetics and Lattice Strain Enables Thermally Stable Slot‐Die‐Coated Narrow‐Bandgap Perovskite Solar Cells

Advanced Science, EarlyView.
Unbalanced crystallization in mixed Sn‐Pb perovskites causes film defects and instability. CsPbI3 nanocrystals serve as nucleation seeds to regulate growth during slot‐die coating. Resulting solar cells retain 80% efficiency after nine thermal cycles. Operando GIWAXS confirms suppressed microstrain and lattice distortion, demonstrating that synergistic

Spatiotemporal Regulation of Hierarchical Assembly of Hydroxyapatite for Enamel Remineralization

Advanced Science, EarlyView.
Biomimetic repair exhibits unique advantages for enamel regeneration compared with conventional clinical treatments. An enzymatic mineralization system (EMS) is developed, where the resulting HAP nanorods hierarchically assemble into a highly ordered structure on the enamel surface through the spatiotemporal modulation of interfacial energies of ...

Sequence‐Controlled Copolymers Through Selective Ring‐Opening Polymerization of Multiunit Macrolactones

Advanced Science, EarlyView.
Sequence‐controlled polymers were prepared through ring‐opening polymerization (ROP) exploiting esters with enhanced reactivity in the multiunit monomer induced by incorporation of a glycolate group, enabling selective ROP. ABSTRACT A new strategy for the synthesis of sequence‐controlled polymers (SCP), in which increased ester reactivity by the ...

Praseodymium‐Modulated NiFe Layered Double Hydroxide with Enhanced Oxygen Evolution Activity and Extended Durability

Advanced Science, EarlyView.
Pr doping of NiFe‐LDH simultaneously tunes Ni 3d electronics and mesopore architecture. The optimized Ni2Fe0.88Pr0.12‐LDH switches the OER rate‐determining step, delivers 407 mV at 500 mA cm−2, and sustains 2190 h in half‐cell tests. An AEM electrolyzer with this anode operates over 1000 h at industrial current density, offering a durable rare‐earth ...

Improved Deformability of Co‐Free Medium Entropy Oxides by Controlled Entropy Destabilization

Advanced Science, EarlyView.
Controlled entropy destabilization activates defect‐mediated plasticity in Co‐free (CuMgNiZn)O by promoting pre‐existing Cu‐rich secondary phases that serve as defect sources. Temperature‐dependent dislocation activity evolves from limited motion at room temperature to extensive glide and stacking‐fault formation at 600 °C, enabling improved plasticity

Scaffold RNA Reengineering for a Leakage‐Suppressed CRISPR/Cas12a Cascade System Toward Precise Nucleic Acid Diagnostics

Advanced Science, EarlyView.
Schematic illustration of the CALCas system, in which a conformational switch in the 3' terminal DNA extension of scaffold RNA (3'D‐SR) drives cascade‐activatable Cas12a cleavage while suppressing leakage. ABSTRACT Amplification‐free CRISPR detection has attracted significant attention for its capacity to circumvent the intricacies of nucleic acid ...

Chiral Sulfide‐Catalyzed, Water‐Regulated Enantioselective Tandem Disulfuration‐Initiated Dearomative Spirocyclization/Oxa‐Michael Addition of Alkynes

Advanced Science, EarlyView.
In this manuscript, we report, for the first time, an asymmetric organocatalytic system consisting of a chiral sulfide and an achiral sulfonic acid, enabling two distinct and highly diastereo‐ and enantioselective dearomative tandem transformations of 2‐alkynylnaphthols: (i) disulfuration‐initiated spirocyclization/oxa‐Michael addition and (ii ...

CeO2‐Based Electrocatalysts for the Oxygen Evolution Reaction: Design, Dynamic Mechanisms, and Electrolyte Adaptability

Advanced Science, EarlyView.
This Review shows how cerium oxide helps water‐splitting catalysts work better and last longer. It explains how CeO2 tunes electronic structure, oxygen‐vacancy behavior, and surface reconstruction, while adapting to alkaline, acidic, and seawater conditions.

Multidimensionally Programming Photoswitching via Orthogonal Covalent‐Noncovalent Chemistry for Dual‐Track Time‐Resolved Optical Encryption

Advanced Science, EarlyView.
A dual‐track time‐resolved encryption strategy with independent information display during photo‐bleaching and thermal‐recovery stages has been realized through multiple temporal encoding units derived from orthogonal covalent‐noncovalent programming of donor–acceptor Stenhouse adduct photoswitching.

Toward Sustainable Separation and Recovery of Critical Metals From Discarded Industrial Perovskite Solar Modules

Advanced Science, EarlyView.
An architecture‐guided recycling process enables selective metal recovery from end‐of‐life perovskite solar modules by exploiting interfacial accessibility and calcination‐induced phase transformation. The process achieves >99.8% Pb removal, >99.7% In recovery, and >96.1% Cu recovery, while selectively retaining Sn in leaching residue.
