Metal (n+1)p‐nd Orbital Hybridization and Excited‐State Metal–Ligand π‐Interactions Enable d10 Carbene‐Metal‐Amide TADF OLEDs with High Efficiency and Long Operational Lifetime

Advanced Science, EarlyView.
We elucidate the key roles of metal p‐d orbital hybridization, excited‐state metal–ligand π‐interactions, and structural rotation in TADF of d10 CMA complexes. Introducing electron‐withdrawing or π‐extended ligand substituents weakens excited‐state metal‐ligand π‐interactions and improves kTADF, but may compromise emitter stability in device operation.

Ultra‐Wide‐Field Noninvasive Imaging Through Scattering Media Via Physics‐Guided Deep Learning

Advanced Science, EarlyView.
We propose a physics‐guided adaptive dual‐domain learning method for ultra‐wide‐field noninvasive imaging through scattering media, namely UNI‐Net. Our method not only reduces the requirement for real experimental data by an order of magnitude but also enables clear imaging of complex scenes with an ultra‐large field of view, which is 164 times the OME

Triple‐Mode Ferroelectric Thin‐Film Transistor for Hybrid Electrical–Optical Reservoir Computing

Advanced Science, EarlyView.
A triple‐mode ferroelectric thin‐film transistor is developed by integrating Si3N4/HZO/IGZO layers to realize three independent memory modes: electric long‐term, electric short‐term, and optical short‐term. This single‐device architecture functions as both a reservoir and readout layer, achieving 92.43% MNIST accuracy. It offers a fully hardware‐based,

Does bad posture affect the standing balance?

Cogent Medicine, 2018
Introduction: Bad posture is a well-known problem in children and adolescents, and it has a negative effect in adulthood. It can be hypothesized that due to bad posture, changes in the body’s position cause changes in standing balance.

Coupled Vacancy and Phonon‐Scattering Engineering Drive Defect Evolution Toward Multifunctional High‐Performance Bi2Te3 Thermoelectrics

Advanced Science, EarlyView.
ZnSb reduces carrier concentration and suppresses Te volatilization, while Se substitution within QLs softens phonons and enhances anharmonicity. Swapped bilayers near twin boundaries strengthen phonon scattering and interlayer bonding. As a result, the optimal sample achieves an ultra‐high zT ∼1.51, cooling temperature difference of ∼70 K, power ...
