Dual Regulation of Molecular Rigidity and Orbital Engineering of Pt(II) Emitters for High‐Performance Deep‐Blue OLEDs

open access: yesAdvanced Science, EarlyView.
Four novel tetradentate Pt(II) emitters (PtCY, PtCY‐F, PtCY‐tBu, PtCY‐tBuF) are designed through synergistic strategy of molecular orbital engineering and steric hindrance effect. PtCY‐tBuF‐based device B4 achieves a high maximum luminance of 45 621 cd m−2, and record high external quantum efficiency (EQE) of 27.1%, 24.3%, and 21.7% at high brightness ...

Mechanism‐Aware Digital Twin for High‐Temperature Creep Prediction in Mo–Re Alloys

open access: yesAdvanced Science, EarlyView.
A digital twin framework enables real‐time monitoring of creep in refractory alloys and reveals dislocation‐drag‐induced Re segregation to grain boundaries. Inspired by this, La2O3 dispersion is introduced to suppress dislocation motion — concurrently mitigating Re segregation and enhancing creep resistance.

Two Types of Non‐Abelian Topological Phase Transitions Under Duality Mapping in 1D Photonic Chains

open access: yesAdvanced Science, EarlyView.
In this work, two types of non‐Abelian phase transitions are revealed. The first type is the braided‐node type, signified by the Dirac degeneracy node moving into or out of the unit circle. The second type corresponds to the emerging of nodal‐line degeneracy which intersects with unit circles.

Sulfur‐Embedded Pure Green Multiple Resonance TADF Emitters: Optimizing Photophysical and Electroluminescent Properties

open access: yesAdvanced Science, EarlyView.
Sulfur atoms are inserted into the multiple‐resonance thermally activated delayed fluorescence framework for developing pure green emitters. The analogous isomers present distinguishing photophysical and electroluminescent properties. The better emitter‐based non‐sensitized device exhibits a maximum external quantum efficiency of 36.4% and a remarkable

Reconstructing Focal Topological Curves through Vortex Spots from Multifocal Metasurfaces

open access: yesAdvanced Science, EarlyView.
Multichannel multifocal silicon metasurfaces are built to reconstruct focal topological curves using an array of vortex spots, and upconverted fluorescence is used to directly visualize the morphology of the near‐infrared focal fields. Abstract Structured light plays an important role in modern photonics.

Phyto‐Confined CeOx with Synergistic Lattice Distortion and Oxygen Vacancies Drives Efficient Urea Electrosynthesis

open access: yesAdvanced Science, EarlyView.
Lattice‐distorted CeOx nanoparticles with abundant oxygen vacancies, confined in porous carbon (d‐CeOx/PC), enable efficient electrocatalytic urea synthesis from CO2 and NO3−. Contracted Ce─O bonds (≈2.29 Å) stabilize OV, creating electron reservoirs for flexible multi‐electron transfer.

Electrosensitive Heterogeneous Short Fibers via Acousto‐Electric Coupling for Sequential Bone Regeneration in Infectious Defects

open access: yesAdvanced Science, EarlyView.
Electrosensitive heterogeneous short fibers can accurately respond to ultrasonic field regulation through the synergistic interaction of piezoelectric and conductive dual elements. At an ultrasound intensity of 1.5 W cm−2, it can effectively activate bacterial peroxisome and necrotic apoptotic pathway and promote bacterial apoptosis.
