Electrochemistry, 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 ...

High-Intensity Synchrotron Radiation Effects [PDF]
CERN Yellow Report CERN-2016-002, pp.63-82, 2016 Various effects of intense synchrotron radiation on the performance of particle accelerators, especially for storage rings, are discussed. Following a brief introduction to synchrotron radiation, the basic concepts of heat load, gas load, electron emission, and the countermeasures against these effects are discussed.

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

Synchrotron radiation in $γ$-ray burst prompt emission [PDF]
, 2020 Growing evidence suggests that synchrotron radiation plays a significant role in shaping the spectra of most $\gamma$-ray bursts. The relativistic jets producing them likely carry a significant fraction of energy in the form of a Poynting flux.

Scientific Reports, 2022 We report an unconventional effect of synchrotron X-ray irradiation in which Co–O bonds in thermally annealed (Y, Co)-codoped CeO2 nanocrystal samples were formed due to, instead of broken by, X-ray irradiation.

SOFT: A synthetic synchrotron diagnostic for runaway electrons [PDF]
, 2017 Improved understanding of the dynamics of runaway electrons can be obtained by measurement and interpretation of their synchrotron radiation emission. Models for synchrotron radiation emitted by relativistic electrons are well established, but the question of how various geometric effects -- such as magnetic field inhomogeneity and camera placement ...

Imaging atelectrauma in Ventilator-Induced Lung Injury using 4D X-ray microscopy
Scientific Reports, 2021 Mechanical ventilation can damage the lungs, a condition called Ventilator-Induced Lung Injury (VILI). However, the mechanisms leading to VILI at the microscopic scale remain poorly understood.

Synchrotron-Self-Compton radiation from magnetically-dominated turbulent plasmas in relativistic jets [PDF]
, 2021 Relativistic jets launched by rotating black holes are powerful emitters of non-thermal radiation. Extraction of the rotational energy via electromagnetic stresses produces magnetically-dominated jets, which may become turbulent. Studies of magnetically-dominated plasma turbulence from first principles show that most of the accelerated particles have ...
