Enabling robust blue circularly polarized organic afterglow through self-confining isolated chiral chromophore

Nature Communications
Creating circularly polarized organic afterglow system with elevated triplet energy levels, suppressed non-radiative transitions, and effective chirality, which are three critical prerequisites for achieving blue circularly polarized afterglow, has posed

Beam profile indicator for swift heavy ions using phosphor afterglow

AIP Advances, 2012
In this letter, we report a beam profile indicator for swift heavy ions (SHIs) which utilizes the afterglow of phosphors. Clear marks are left on SrAl2O4:Eu2+ and CaSrAl2Si2O8:Eu2+ samples by SHI irradiation through a permanent change of their afterglow ...

The shallow-decay phase in both optical and x-ray afterglows of Swift GRB 090529A: Energy injection into a wind-type medium? [PDF]

, 2012
The energy injection model is usually proposed to interpret the shallow-decay phase in Swift GRB X-ray afterglows. However, very few GRBs have simultaneous signatures of energy injection in their optical and X-ray afterglows.

Ion Chemistry in Dielectric Barrier Discharge Ionization: Recent Advances in Direct Gas Phase Analyses

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Dielectric barrier discharge ionization (DBDI) sources, employing low‐temperature plasma, have emerged as sensitive and efficient ionization tools with various atmospheric pressure ionization processes. In this review, we summarize a historical overview of the development of DBDI, highlighting key principles of gas‐phase ion chemistry and the ...

Thermometer Ions, Internal Energies, and In‐Source Fragmentation in Ambient Ionization

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Ionization and fragmentation are at the core of mass spectrometry. But they are not necessarily separated in space, as in‐source fragmentation can also occur. Here, we survey the literature published since our 2005 review on the internal energy and fragmentation in electrospray ionization sources.

On the External Inverse Compton Scattering off the Prompt Emission in GRB 221009A

The Astrophysical Journal
The temporal evolution of the TeV emission of GRB 221009A displays a smooth transition from an initial rapid rise to a slower rise and eventually a decay phase. The smooth light curve suggests an afterglow origin of the TeV emission. The temporal overlap
