Mechanisms of Aristolochic Acid Resistance in Specialist Butterflies and Evolutionary Insights for Potential Protective Pathways

Advanced Science, EarlyView.
The study provides an extreme example of insect adaptation to highly toxic defenses of host plants, and investigates the complex strategies to resist carcinogenic aristolochic acids, including physical isolation, metabolic detoxification, and DNA repair.

Lattice Strain and Piezoelectric Field Modulated Piezo‐Photocatalytic Nitrate‐to‐Ammonia Conversion in Chemically Bonded S‐Scheme Heterojunction

Advanced Science, EarlyView.
Under ultrasonic excitation, 5% compressive strain optimizes the ZnO@ZnSe heterojunction. The strain enhances H2O dissociation into active *H on Zn sites and NO3− adsorption on Se sites, facilitating their hydrogenation into NH4+ with optimal kinetics and thermodynamics. Abstract Piezo‐photocatalysis provides an efficient approach to harness mechanical

Structure‐Function Integration in 2D Hybrid Perovskite for Fast Neutron and Gamma Ray Discrimination

Advanced Science, EarlyView.
Using an in situ seed‐assisted cooling method, large (28 × 7 × 3 mm3) (GABA)2PbBr4 single crystals are grown, featuring hydrogen‐rich organic layers and a dense PbBr4 framework. This architecture enables efficient γ‐ray absorption, fast‐neutron sensitivity, and clear n/γ pulse‐shape discrimination (FOM up to 1.74), highlighting its potential as a ...

A Generalized Approach for Distal C–H Arylation of Organic Building Blocks: Unveiling the Role of Counter Anion

Advanced Science, EarlyView.
We report a general strategy for meta‐selective C–H arylation using aryl iodides and a Pd(II)/Pd(IV) catalytic system guided by a removable directing group. DFT and experimental studies reveal that counter anion tuning (acetate to trifluoroacetate) significantly enhances selectivity.
