Radiation Protection at Synchrotron Radiation Facilities [PDF]

open access: yesRadiation Protection Dosimetry, 2001
A synchrotron radiation (SR) facility typically consists of an injector, a storage ring, and SR beamlines. The latter two features are unique to SR facilities, when compared to other types of accelerator facilities. The SR facilities have the characteristics of low injection beam power, but high stored beam power.

Stability of iron-bearing carbonates in the deep Earth’s interior

open access: yesNature Communications, 2017
Carbonates are shown to exist in the lower mantle as seen in diamond inclusions, but thermodynamic constraints are poorly understood. Here, the authors synthesise two new iron carbonate compounds and find that self-oxidation-reduction reactions can ...

In-situ spectroscopic observation of dynamic-coupling oxygen on atomically dispersed iridium electrocatalyst for acidic water oxidation

open access: yesNature Communications, 2021
Uncovering the dynamics of active sites in the working conditions is important yet challenging. Here the authors identify dynamic-coupling oxygen on atomically dispersed iridium sites during oxygen evolution reaction using in situ techniques.

1.8 V Aqueous Symmetric Carbon-Based Supercapacitors with Agarose-Bound Activated Carbons in an Acidic Electrolyte

open access: yesNanomaterials, 2021
The specific energy of an aqueous carbon supercapacitor is generally small, resulting mainly from a narrow potential window of aqueous electrolytes.

Synchrotron radiation from ultra-high energy protons and the Fermi observations of GRB 080916C

open access: yes, 2010
Fermi gamma-ray telescope data of GRB 080916C with ~1e55 erg in apparent isotropic gamma-ray energy, show a several second delay between the rise of 100 MeV - GeV radiation compared with keV - MeV radiation.

Intrinsic room-temperature ferromagnetism in a two-dimensional semiconducting metal-organic framework

open access: yesNature Communications, 2023
The development of two-dimensional (2D) magnetic semiconductors with room-temperature ferromagnetism is a significant challenge in materials science and is important for the development of next-generation spintronic devices. Herein, we demonstrate that a

Capacity Deterioration Analysis of Li-ion Battery Cathode Li[Ni1/3Co1/3Mn1/3]O2 Material by Soft X-ray Absorption Spectroscopy

open access: yesElectrochemistry, 2021
We report detailed studies of capacity deterioration mechanism of Li[Ni1/3Co1/3Mn1/3]O2 (NCM) cathode after several numbers of cycling with the voltage range of 3.0–4.1 V/cell at 85 °C and after storage at charged states (3.7, 4.0 and 4.1 V/cell) at 70 ...
