Effects of neutron exposure on the embryonic development of European sea bass (Dicentrarchus labrax), a candidate fish species for space aquaculture: simulated conditions on the ISS and during a lunar mission

Frontiers in Space Technologies
One of the scenarios for manned space exploration involves the presence of a community on a lunar base that is partially autonomous in terms of food production.

Large-Scale Boron-Lined Neutron Detection Systems as a 3He Alternative for Cosmic Ray Neutron Sensing

Frontiers in Water, 2020
Cosmic-Ray neutron sensors are widely used to determine soil moisture on the hectare scale. Precise measurements, especially in the case of mobile application, demand for neutron detectors with high counting rates and high signal-to-noise ratios.

Neutron features at the UPM neutronics hall [PDF]

Applied Radiation and Isotopes, 2012
The neutronics hall of the Nuclear Engineering Department at the Polytechnical University of Madrid has been characterized. The neutron spectra and the ambient dose equivalent produced by an (241)AmBe source were measured at various source-to-detector distances on the new bench.

On the Effect of Creep on Local Lattice Orientation in Single‐Crystal Ni‐Based Superalloy Microstructures

Advanced Engineering Materials, EarlyView.
During creep of a single‐crystal Ni‐based superalloy, the overall crystal orientation is observed to remain constant while the microstructure evolves. Despite the lack of macroscopic rotation, small (<1°) rotations are observed on the submicron size scale and are accommodated by counteracting rotations over the scale of several micrometers.

Foundational Machine‐Learning Interatomic Potential for Simulating Chemically Complex Ni‐Based Superalloys

Advanced Engineering Materials, EarlyView.
We apply a foundational machine‐learning interatomic potential based on the graph atomic cluster expansion (GRACE) to simulate the commercial Ni‐based single‐crystal superalloy CMSX‐4. Hybrid Monte‐Carlo/molecular dynamics sampling resolves short‐range order in the γ phase and L12 sublattice occupancies in the γ’ phase and connects them to stacking ...

Measuring the yields and angular distributions of γ-quanta from the interaction between 14.1 MeV neutrons and sodium nuclei

Eurasian Journal of Physics and Functional Materials, 2021
A study of the reaction of inelastic scattering of 14.1 MeV neutrons by 23 Na nuclei was carried out at the TANGRA facility using the tagged neutron method. In this work, the energies of visible . transitions are determined, the yields of .
