Observation of Pulsed γ-Rays Above 25 GeV from the Crab Pulsar with MAGIC

open access: yes, 2008
One fundamental question about pulsars concerns the mechanism of their pulsed electromagnetic emission. Measuring the high-end region of a pulsar's spectrum would shed light on this question.

COSMIC-RAYS AND GAMMA RAY BURSTS

open access: yesEAS Publications Series, 2013
Cosmic-rays are subatomic particles of energies ranging between a few eV to hundreds of TeV. These particles register a power-law spectrum, and it seems that most of them originate from astrophysical galactic and extragalactic sources. The shock acceleration in superalfvenic astrophysical plasmas, is believed to be the main mechanism responsible for ...

Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

open access: yesAdvanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

Gamma ray astronomy in the low energy range

open access: yes, 1979
A low energy gamma ray telescope, and the results of its observations are described. The telescope consisted of four sodium iodide crystals, each of 120 cm2 area, occulted by lead discs.

A search for TeV gamma ray emission from X-ray binary stars [PDF]

open access: yes, 1993
This work is concerned with the detection of pulsed TeV gamma ray emission from a number of X-ray binary systems by the use of the atmospheric Cerenkov technique.

The protective action of osmolytes on the deleterious effects of gamma rays and atmospheric pressure plasma on protein conformational changes

open access: yesScientific Reports, 2017
Both gamma rays and atmospheric pressure plasma are known to have anticancer properties. While their mechanism actions are still not clear, in some contexts they work in similar manner, while in other contexts they work differently.

Liquid Phase Transmission Electron Microscopy: A Window into the Early Stages of Complex Material Formation

open access: yesAdvanced Functional Materials, EarlyView.
Liquid‐phase transmission electron microscopy enables direct observation of nucleation and growth processes in solution. This review is dedicated to the remembrance of Helmut Cölfen and highlights recent studies on complex materials—oxides, biominerals, organic–inorganic crystals—which were central to his research activity. It summarizes key milestones,

Determination of the linear attenuation coefficients of aluminum, iron and lead for collimated 661.66 keV gamma rays using TCS-172 gamma scintillation survey meter [PDF]

open access: yes
The linear attenuation coefficients of aluminum (Al), iron (Fe), and lead (Pb) for 661.66 keV gamma rays were determined based on gamma dose rate measurements obtained using a handheld TCS-172 gamma scintillation survey meter.
