Managing Charge Transport and Exciton Generation for Highly Efficient, Bright, and Stable Near‐Infrared Organic Radical Light‐Emitting Diodes

Advanced Functional Materials, EarlyView.
High‐performing near‐infrared (NIR) organic light‐emitting diodes are demonstrated using an efficient and stable 800 nm‐emissive organic radical and a thermally activated delayed fluorescence (TADF) host. TADF‐assisted exciton generation combined with improved charge transport enables high external quantum efficiency (>8%), high radiance (>70,000 mW sr−

Orbital symmetry fingerprints for magnetic adatoms in graphene

New Journal of Physics, 2014
In this paper, we describe the formation of local resonances in graphene in the presence of magnetic adatoms containing localized orbitals of arbitrary symmetry, corresponding to any given angular momentum state. We show that quantum interference effects

Selenium‐Integrated Cyanine Dye With Enhanced Photophysical Properties for Optoacoustic‐Guided Cancer Imaging and Therapy

Advanced Functional Materials, EarlyView.
This study introduces selenium‐integrated cyanine dye (Se‐Cyn), with superior photostability, absorption, and photothermal efficiency, outperforming ICG in NIR window. Its nanoparticle form remains stable in water, accumulates in tumors, and enables strong optoacoustic imaging and effective phototherapy outcomes.

A Library of 77 Multibody Solar and Extrasolar Subsystems—A Review of Their Dynamical Properties, Global Mean-Motion Resonances, and the Landau-Damped Mean Tidal Fields

Astronomy
We revisit 77 relaxed (extra)solar multibody (sub)systems containing 2–9 bodies orbiting about gravitationally dominant central bodies. The listings are complete down to (sub)systems with 5 orbiting bodies and additionally contain 33 smaller systems with

Strength of higher-order spin-orbit resonances [PDF]

Physical Review E, 2004
When polarized particles are accelerated in a synchrotron, the spin precession can be periodically driven by Fourier components of the electromagnetic fields through which the particles travel. This leads to resonant perturbations when the spin-precession frequency is close to a linear combination of the orbital frequencies.

On the orbital picture of shape resonances using Feynman–Dyson amplitudes from different decouplings of the dilated electron propagator

, 1994
The orbital picture of shape resonances is investigated by examining the radial charge density distributions calculated from resonant Feynman-Dyson amplitudes for the P-2 Shape resonances in e-Be, e-Mg, and e-Ca scattering using the zeroth (bivariational

Engineering Intraframework Energy Transfer in Metal‐Organic Frameworks for Luminescent Discrimination of Bisphenol Pollutants

Advanced Functional Materials, EarlyView.
A family of isostructural lanthanide metal–organic frameworks serves as a model platform to disentangle metal‐to‐metal and linker‐to‐linker energy transfer during luminescence sensing. The results reveal that rigid lanthanide energy migration governs sensing performance, whereas linker‐mediated pathways exert only minor effects, providing mechanistic ...

Dynamical mirages: How bar-induced resonant trapping can mimic substructure clustering in dynamical parameter spaces

Astronomy & Astrophysics
Context. The complex task of unraveling the assembly history of the Milky Way evolves constantly, and new substructures are identified continuously. To properly validate and characterise the family of galactic progenitors, it is important to take all the
