The Effect of Neutron Fluence at High Temperatures on Strength Nuclear Graphite: Based on Elasticity [PDF]

E3S Web of Conferences
The main structural component and moderator in a high-temperature gas-cooled reactor (HTGR) is nuclear graphite. The long-term performance of these components is greatly influenced by exposure to high neutron fluence at operational temperatures above 600°

Advances in Halide Perovskites for Photon Radiation Detectors

Advanced Materials Technologies, EarlyView.
This work highlights recent progress in perovskite‐based photon radiation detectors, covering organic–inorganic hybrid, inorganic, lead‐free double, and vacancy‐ordered halide perovskites. Their detection performance is compared, material‐specific advantages and challenges are examined, and provides insight into current limitations and future ...

Neutron stars velocities and magnetic fields

EPJ Web of Conferences, 2018
We study a model that explain neutron stars velocities due to the anisotropic emission of neutrinos. Strong magnetic fields present in neutron stars are the source of the anisotropy in the system.

High‐Performance Piezoelectric Nanogenerators Based on Wurtzite BeO Nanowire Arrays

Advanced Materials Technologies, EarlyView.
This study demonstrates high‐performance piezoelectric nanogenerators based on 1D BeO nanowire arrays. The BeO nanowires exhibit a high piezoelectric coefficient (∼15.8 pm V−1) and deliver an output voltage of ∼26.1 V and power density of ∼0.32 µW cm−2.

Equilibria and oscillations of magnetised neutron stars

, 2010
We investigate equilibrium configurations and oscillation spectra of neutron stars,modelled as rotating magnetised fluid bodies in Newtonian gravity. We also explorethe idea that these model neutron stars could have dynamics analogous to rigid-bodyfree ...

On the spectrum of moderated neutrons emitted by the isotropic source in the gas fuel

Ядерна фізика та енергетика, 2016
Analytical formula for the equation of the neutron scattering for isotropic neutron source, which includes the temperature of the moderating medium as the parameter, was first obtained in the given work in the framework of gas model of the medium.

3D‐Printed Dual‐Doped Ag2Se‐Based Thermoelectric Films With Enhanced Thermal Stability

Advanced Materials Technologies, EarlyView.
Sb–Se dual doping enhances the thermal stability of Ag2Se‐based thermoelectric systems. The compositionally tuned nano‐ink is printed into flexible films by direct ink writing (DIW), retaining improved thermoelectric properties after annealing up to 400°C.

Thermodynamics of Concomitant Charge‐Transfer, Antiferromagnetic, and Isostructural Phase Transitions in Barocaloric ACu3Fe4O12 Quadruple Perovskites

Advanced Science, EarlyView.
A copper‐iron charge transfer instability drives concomitant electronic, magnetic, and isostructural phase transitions in ACu3Fe4O12${\rm ACu}_3{\rm Fe}_4{\rm O}_{12}$, with an inverse barocaloric effect. A minimal Landau theory ties these thermodynamic signatures together, revealing a pressure‐independent transition entropy with comparable charge and ...

Displacive In‐Plane Ferroelectricity with Domain‐Specific Curie Temperature in Van der Waals Semiconductors

Advanced Science, EarlyView.
Temperature‐dependent electron diffraction on tin monochalcogenides demonstrates a gradual displacive transformation between ferroelectric and paraelectric phases with significant variability in lattice constants and Curie temperature (TC). Periodic variations exist even between domains in individual crystals, implying a domain‐specific Curie ...

Enzyme activity and flexibility at very low hydration [PDF]

, 2005
Recent measurements have demonstrated enzyme activity at hydrations as low as 3%. This raises the question of whether hydration-induced enzyme flexibility is important for activity. Here, to address this, picosecond dynamic neutron scattering experiments
