Metasurfaces and Metadevices for Topological Electromagnetic Waves

Advanced Physics Research, EarlyView.
Optical topologies refer to diverse topological localized structures made by diverse parameters of light fields, such as vortices, skyrmions, and hopfions. This article navigates a direction of metasurface‐based integrated devices for generation, manipulation and detection of novel topologies of light, which would be a rapidly growing interdisciplinary

The Progress of Orbitronics: The Enhancement of Orbital Torque Efficiency

Advanced Physics Research, EarlyView.
Orbit‐torque (OT) devices attract significant attention for their low‐power consumption and high stability in applications. This review systematically outlines strategies for enhancing OT efficiency. We categorize approaches into boosting orbital currents/torques and improving the orbital‐to‐spin conversion coefficient.

A Review of Transient Characterization Techniques for Quantum Dot Light‐Emitting Diodes

Advanced Physics Research, EarlyView.
This review surveys transient characterization techniques for quantum dot light‐emitting diodes, including TRPL, TREL, TA, and E‐TA. These methods resolve carrier‐selective dynamics across multiple time scales, enabling direct analysis of charge injection, exciton formation and recombination, efficiency roll‐off, and device degradation.

Polarization anisotropy identifies bound azide in photoexcited ferric myoglobin: Resolving photodeligation ambiguity by femtosecond infrared spectroscopy

Bulletin of the Korean Chemical Society, EarlyView.
Polarization‐resolved femtosecond TRIR reveals that the transient absorption in MbN3 arises from a bound azide ligand, not photodissociation. Identical anisotropy confirms preserved orientation, demonstrating that Q‐band excitation leads to thermal relaxation without photodeligation, clarifying the photophysics of anion‐bound ferric heme proteins ...
