Research progress on SiC irradiation temperature monitors for reactors

He jishu, 2023
Silicon carbide (SiC) crystal can be used as a passive monitor to measure the neutron irradiation temperature in nuclear reactors, which has significant application prospects for advanced reactors operating in high-temperature intense irradiation ...

Impact of Rotation-Driven Particle Repopulation on the Thermal Evolution of Pulsars [PDF]

, 2012
Driven by the loss of energy, isolated rotating neutron stars (pulsars) are gradually slowing down to lower frequencies, which increases the tremendous compression of the matter inside of them.

X-ray and Neutron Scattering of Water.

Chemical Reviews, 2016
This review article focuses on the most recent advances in X-ray and neutron scattering studies of water structure, from ambient temperature to the deeply supercooled and amorphous states, and of water diffusive and collective dynamics, in disparate ...

Dynamical mass ejection from binary neutron star mergers: Radiation-hydrodynamics study in general relativity [PDF]

, 2015
We perform radiation-hydrodynamics simulations of binary neutron star mergers in numerical relativity on the Japanese "K" supercomputer, taking into account neutrino cooling and heating by an updated leakage-plus-transfer scheme for the first time ...

Understanding the Role of Hydrogen and Oxygen in Electronic Phase Changes of Nickelates

Advanced Functional Materials, EarlyView.
The reversible exchange of hydrogen and oxygen in solids is key to their electronic and electro‐chemical functionality. A combination of methods is employed to study the interaction of hydrogen with a prototypical quantum material in a non‐destructive and time‐dependent manner.

Intensity of the neutron component of cosmic rays and air humidity

Solar-Terrestrial Physics
Neutron monitor data is currently corrected only for the barometric effect. We cannot, however, exclude that changes in air humidity affect the intensity of the cosmic-ray neutron component recorded by neutron monitors.

Rapid Cooling of the Neutron Star in Cassiopeia A Triggered by Neutron Superfluidity in Dense Matter

, 2011
We propose that the observed cooling of the neutron star in Cassiopeia A is due to enhanced neutrino emission from the recent onset of the breaking and formation of neutron Cooper pairs in the 3P2 channel.

Neutron activations for lower s-process temperatures

EPJ Web of Conferences, 2023
The slow neutron capture process produces heavy elements in different stellar sites at different temperatures. Neutron capture cross sections for stellar temperatures between kBT = 5 keV and kBT = 100 keV are crucial for a quantitative understanding of the s-process abundance distribution.

Neutron matter from chiral two- and three-nucleon calculations up to N$^3$LO [PDF]

, 2016
Neutron matter is an ideal laboratory for nuclear interactions derived from chiral effective field theory since all contributions are predicted up to next-to-next-to-next-to-leading order (${\mathrm{N}}^{3}\mathrm{LO}$) in the chiral expansion. By making
