Multipolar Resonances in Electro‐Optic Metasurfaces with Moderate Refractive Index

Advanced Photonics Research, EarlyView.
Electro‐optic nanoantennas with moderate refractive indices of 2.3 to 3.0 are numerically shown to sustain strong multipolar resonances, enabling efficient light confinement and EO tuning. Multipolar modes of even parity are most sensitive to variations in the refractive index.

Bacteria and Fungi Synergistically Reprogram Flavonoid Metabolites in the Pericarp of Citrus Reticulata 'Chachi' During Storage

Advanced Science, EarlyView.
The authors employed widely targeted metabolomics, microbial amplicon sequencing, and fermentation assays to investigate the microbiome 's influence on PCRC 's (pericarp of Citrus reticulata ' Chachi ') flavonoid profile over 0–19 years of storage. Based on the correlation analysis, solid‐state and liquid‐state fermentation, and catalytic activity ...

Mitochondrial Calcium Uniporter Drives Chemoresistance in Pancreatic Cancer via Glutathione‐Mediated Stemness Maintenance

Advanced Science, EarlyView.
PDAC has a poor prognosis due to chemoresistance. We revealed that MCU upregulation is associated with chemoresistance and stemness in PDAC. MCU‐mediated Ca2+ influx induced ER stress, activating the PERK‐ATF4/NRF2 axis to enhance PSAT1/SLC711 expression and glutathione synthesis, reducing ROS and maintaining stemness.

Dual‐Array Nano Configuration for High‐Performance Metastable β Titanium Alloys

Advanced Science, EarlyView.
This work resolves a fundamental paradox in metastable alloys by establishing a novel dislocation‐phase coupling mechanism, enabling dynamic microstructure control for simultaneous thermal stability and deformability. Geometrically ordered α‐nanograins achieve unprecedented 500°C strength‐ductility synergy (863 MPa UTS, 78.3% elongation).
