Small-scale Magnetic Fields Are Critical to Shaping Solar Gamma-Ray Emission

open access: yesThe Astrophysical Journal
The Sun is a bright gamma-ray source due to hadronic cosmic-ray interactions with solar gas. While it is known that incoming cosmic rays must generally first be reflected by solar magnetic fields to produce outgoing gamma rays, theoretical models have ...

Engineering a Fluorinated AlPO4 Interface: Toward High Initial Coulombic Efficiency and Stable Oxygen Redox in Li‐Rich Layered Oxide Cathodes

open access: yesAdvanced Functional Materials, EarlyView.
We report a chemically incorporated fluorinated AlPO4 (AlPO4‐F) architecture that functions as a multifunctional “interfacial fortress” for Li‐rich layered oxides (LLOs). By modulating the surface potential to –32.16 mV, this architecture enriches Li+ concentration and repels detrimental electrolyte anions.

An angular correlation of positron annihilation gamma radiation with a NaI (T1) detector and a Ge (Li) detector

open access: yes, 1970
Several high quality electronic units were previously acquired on an individual basis from various manufacturers. As the second research effort in a planned complementary series of papers, the capability of the total array of equipment to accomplish ...

Neutron/Gamma Mixed Spectrum Radiolysis-based Aqueous Dosimetry [PDF]

open access: yes, 2007
This work develops a method to use an aqueous dosimeter in a mixed radiation field to determine separate measurements of neutron and gamma dose. Based on radiolysis of both Fricke and Methyl Viologen (MV) solutions, activation analysis and reactor ...

Ligand Assisted Epitaxial Growth of CsPbBr3 Microcrystal Resonators With Record ‐Low Lasing Thresholds

open access: yesAdvanced Functional Materials, EarlyView.
Solution‐based ligand‐assisted epitaxial growth (LAEG) yields high‐quality CsPbBr3 microcrystals on different substrates with superior morphology, passivated surfaces, and high photoluminescence quantum yield. These robust micro‐resonators achieve record‐low room‐temperature lasing thresholds of 7.2 kW·cm−2 and maintain operational stability up to 90 ...

Gamma Rays: Technology, applications and health implications

open access: yes, 2013
Gamma-rays originate from the decay of excited states of the atomic nuclei in a similar manner as the visible light originates from the decay of the atom itself.

Focusing of gamma-rays with Laue lenses: first results

open access: yes, 2008
We report on the first results obtained from our development project of focusing gamma-rays (>60 keV) by using Laue lenses. The first lens prototype model has been assembled and tested.

Unified Pressure and Field Response Across Distinct Charge‐Order Regimes in Ti‐Doped CsV3Sb5

open access: yesAdvanced Functional Materials, EarlyView.
We microscopically investigate the interplay between charge order and superconductivity in a kagome superconductor across regimes of long‐ and short‐range charge order. Hydrostatic‐pressure and magnetic‐field μSR$\mu{\rm SR}$ measurements reveal remarkably similar superconducting and normal‐state time‐reversal‐symmetry‐breaking responses in both ...

Thermal-neutron capture gamma-rays. Volume 1

open access: yes, 1997
The energy and photon intensity of gamma rays as seen in thermal-neutron capture are presented in ascending order of gamma energy. All those gamma-rays with intensity of {ge} 2% of the strongest transition are included. The two strongest transitions seen
