Charge decay in the spatial afterglow of plasmas and its impact on diffusion regimes
Nature Communications, 2023 The spatial afterglow is a region at the boundary of a non-equilibrium plasma where charged species relax into ambient equilibrium. In many applications, the spatial afterglow is the part of the plasma that interacts with surfaces, such as suspended ...

Global properties of X-ray afterglows of GRB [PDF]
, 2005 In this paper we review the general properties of X-ray afterglows. We discuss in particular on the powerful diagnostics provided by X-ray afterglows in constraining the environment and fireball in normal GRB, and the implications on the origin of dark ...

Moth‐Eye‐Engineered Flexible Films for X‐Ray Shielding and Persistent Radiation Warning
Advanced Science, EarlyView.A moth‐eye‐engineered film SrAl2O4:Eu2+, Dy3+@SiO2 (SOD@SiO2) that integrates X‐ray shielding, persistent luminescence, and high‐resolution imaging. It bridges nighttime maritime rescue, radiation protection, and real‐time X‐ray hazard alerts, overcoming traditional trade‐offs between performance and environmental resilience.

The afterglows of gamma-ray bursts [PDF]
, 2000 Gamma-ray burst astronomy has undergone a revolution in the last three years, spurred by the discovery of fading long-wavelength counterparts. We now know that at least the long duration GRBs lie at cosmological distances with estimated electromagnetic ...

Advanced Science, EarlyView.Ultra‐bright Cd0.27Zn0.73S/7 ML‐ZnS core/shell quantum dots exhibit a photoluminescence quantum yield exceeding 96% and a fourfold enhancement in radioluminescence intensity compared to CsPbBr3. Variable‐temperature photophysical analysis reveals that the narrowband emission originates from direct recombination of edge excitons.

Diverse Temporal Properties of GRB Afterglow
, 1998 The detection of delayed X-ray, optical and radio emission, "afterglow", associated with $\gamma$-ray bursts (GRBs) is consistent with fireball models, where the emission are produced by relativistic expanding blast wave, driven by expanding fireball at ...

Modeling GRB 050904: Autopsy of a Massive Stellar Explosion at z=6.29 [PDF]
, 2006 GRB 050904 at redshift z=6.29, discovered and observed by Swift and with spectroscopic redshift from the Subaru telescope, is the first gamma-ray burst to be identified from beyond the epoch of reionization. Since the progenitors of long gamma-ray bursts

Advanced Science, EarlyView.In this contribution, the coordination‐locked phosphorescence amplification (CLPA) strategy is developed to successfully construct the first non‐rare‐earth narrowband RTP MOF crystal, Sr–tbc. In addition, Sr–tbc shows potential applications in high‐resolution afterglow display and multilevel information recognition.
