Three-step Acceleration of the Radiation Belt Relativistic Electrons by Interplanetary Shocks

The Astrophysical Journal Supplement Series
Inward radial diffusion driven by ultra-low-frequency (ULF) waves is one of the dominant acceleration mechanisms of relativistic (>1.0 MeV) electrons in the Earth’s outer radiation belt.

Eutectic Gallium‐Indium as a Potential Non‐Toxic Replacement in Mercury Intrusion Porosimetry

Advanced Materials Technologies, EarlyView.
A practical alternative to mercury intrusion porosimetry is presented using non‐oxidized eutectic gallium‐indium. An eGaIn Filling Station enables oxygen‐free preparation of standard penetrometers, and the resulting measurements faithfully reproduce pore‐size distributions and intrusion volumes measured with mercury across several standard reference ...

On steady Tokamak with Relativistic Electrons

Kakuyūgō kenkyū, 1972
A simple method of maintaining a toroidal current in resistive plasmas is proposed. A high current relativistic electron ring with its major radius approximately equal to that of toroidal plasma and a low intensity ion beam are injected into the plasma.

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.

Synchrotron Polarization of a Hybrid Distribution of Relativistic Thermal and Nonthermal Electrons in Gamma-Ray Burst Prompt Emission

The Astrophysical Journal
Synchrotron polarization of relativistic nonthermal electrons in gamma-ray bursts (GRBs) has been widely studied. However, recent numerical simulations of relativistic shocks and magnetic reconnection have found that a more realistic electron ...

Stochastic electron motion driven by space plasma waves [PDF]

Nonlinear Processes in Geophysics, 2014
Stochastic motion of relativistic electrons under conditions of the nonlinear resonance interaction of particles with space plasma waves is studied. Particular attention is given to the problem of the stability and variability of the Earth's radiation ...

Sliding Ferroelectricity Driven Spin‐Layertronics in Altermagnetic Multilayers

Advanced Science, EarlyView.
Integrating sliding ferroelectricity with altermagnetism enables nonvolatile electrical control of spin and layer degrees of freedom. In bilayer CuF2, interlayer translation reverses layer‐locked spin‐split bands, establishing a multifunctional “spin‐layertronic” platform.

Selenophene π‐Core Fusion for Simultaneous Fast Reverse Intersystem Crossing and Narrowband Long‐Wavelength TADF

Angewandte Chemie, EarlyView.
Dibenzo[b,d]selenophene (DBSe) π‐core fusion enables rapid triplet–singlet interconversion while preserving the narrowband emission features of multi‐resonance thermally activated delayed fluorescence (MR‐TADF) luminogens. Combined with peripheral donor engineering, this strategy enables systematic emission tuning from green to red, leading to highly ...
