Dimensional Engineering of Wet‐Spun MOF‐Based Woven Fabrics for Superior Electromagnetic Wave Absorption

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work fabricated MOF‐based woven absorbing fabrics with dimensional engineering via a wet spinning strategy. The absorbing fabrics achieve a reflection loss of −51.47 dB at 2.9 mm, with an effective absorption bandwidth reaching 3.54 GHz. The absorbing fabrics can be freely bent, stretched, and folded, with individual fibers exhibiting a break ...

Liquid‐Mediated Kinetically Controlled Synthesis of Porous Carbon with Homogeneous Graphitic Networks for High‐Rate and High‐Loading Organic Supercapacitor

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Liquid‐mediated kinetic control reconstructs a “rigid–flexible” carbon precursor into homogeneously graphitized porous carbon. The resulting porous structure and homogeneous graphitic network accelerate ion/electron transport, enabling superior performance in high‐rate and high‐loading organic supercapacitors.

A Robust Densification Strategy Toward Ultrahigh Energy Density in All‐Organic Dielectric Polymer Films

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A scalable densification strategy is proposed by incorporating sucrose into a fluoropolymer matrix to build a robust hydrogen‐bond crosslinking network. The intermolecular interactions effectively facilitate polar phase transformation and reduce free volume fraction.

Ni Nanoparticle‐Decorated Reduced Graphene Oxide Hybrids With Tunable Dielectric–Magnetic Synergy for Efficient Microwave Absorption

Electron, EarlyView.
Optimized Ni nanoparticle loading on reduced graphene oxide creates abundant Ni/rGO heterointerfaces, enhancing interfacial polarization, conductive loss, magnetic loss, and impedance matching. The rGO/Ni‐5 hybrid achieves efficient microwave absorption at only 15 wt.% filler loading, delivering a minimum reflection loss of −35.5 dB and an effective ...

Endohedral fullerenes as qubits: From synthesis to quantum computing applications

InfoMat, EarlyView.
Endohedral fullerenes emerge as promising platforms for qubits and qudits. This review surveys the primary synthesis routes, from arc‐discharge to high‐yield molecular surgery. It then details spin manipulation and readout in key systems, including metal‐based, cluster, and nitrogen‐containing fullerenes.

A Complex‐Frequency Framework for Kerker Unidirectionality in Photonic Resonators

Laser &Photonics Reviews, EarlyView.
ABSTRACT Electromagnetic scattering exhibits various anomalous behaviors, such as forward or backward scattering effects known as the Kerker conditions. These anomalies appear in non‐Hermitian photonic resonators and are mathematically described by operators with complex eigenfrequencies.

Dielectric Nanoparticle Dimers on a Mirror for Enhanced Photoluminescence of Quantum Dots [PDF]

Nanophotonics
Hybrid metal–dielectric nanoantennas based on nanoparticle‐on‐mirror architectures are proposed to enhance quantum dot photoluminescence. Silicon nanocylinder dimers on aluminum substrates enable simultaneous excitation enhancement and directional emission through strong light–matter interactions.

Quantization of Polaritons Confined in Dielectric Structures

Laser &Photonics Reviews, EarlyView.
This study addresses the limitations of the Hopfield model of strong light‐matter coupling in the case of structured dieletrics. A method to derive quantum models in the polariton basis using Bogoliubov transformation and third quantization is introduced, demonstrating how to boost interaction strength and engineer nonlocal interactions for strongly ...

Resonant States Reveal Strong Light–Matter Coupling in Nanophotonic Cavities

Laser &Photonics Reviews, EarlyView.
Photonic resonant states reveal characteristics of coupled light–matter systems that would otherwise be hidden by damping. Their trajectories (when tuning the optical resonance) undergo a qualitative change at the onset of strong coupling: They start swapping positions.
