Multimodal confined water dynamics in reverse osmosis polyamide membranes

open access: yesNature Communications, 2022
Polymeric membranes are extensively used in water desalination, but the effect of membrane nanostructure on water transport is still elusive. The authors, using quasi-elastic neutron scattering and contrast variation techniques, provide detailed insight ...

Incommensurate structure of AlPO<sub>4</sub>-5 and its stability. [PDF]

open access: yesActa Crystallogr B Struct Sci Cryst Eng Mater
The incommensurately modulated structure of AlPO4‐5 was elucidated by single‐crystal X‐ray diffraction, revealing correlated rotational displacements of AlO4 and PO4 tetrahedra.The incommensurate structure of AlPO4‐5 and its stability have been investigated in detail.

Towards the experimental validation of a small Time-Projection-Chamber for the quasi-absolute measurement of the fission cross section [PDF]

open access: yesEPJ Web of Conferences, 2021
To accurately measure neutron-induced fission cross sections, to characterize neutron-beam lines or to make dosimetric investigations, it is necessary to have high accuracy measurements of neutron fluence.

Proton Dynamics in Palladium–Silver: An Inelastic Neutron Scattering Investigation

open access: yesMolecules, 2020
Proton dynamics in Pd77Ag23 membranes is investigated by means of various neutron spectroscopic techniques, namely Quasi Elastic Neutron Scattering, Incoherent Inelastic Neutron Scattering, Neutron Transmission, and Deep Inelastic Neutron Scattering ...

Revisiting the modeling of quasielastic neutron scattering from bulk water [PDF]

open access: yesEPJ Web of Conferences, 2022
Quasi-elastic neutron scattering (QENS) from bulk-water at 300 K, measured on the IRIS backscattering neutron spectrometer (ISIS, UK), is interpreted using the jump diffusion model (JDM), a “minimalistic” multi-timescale relaxation model (MRM) and ...

Method to Compare Fission-to-Scattering Ratios using Uranium-238 [PDF]

open access: yesEPJ Web of Conferences, 2023
A novel method was developed to separate the 238U fission contribution measured in quasi-differential time-of-flight scattering experiments in order to isolate the elastic and inelastic events.

Low-energy neutron-deuteron reactions with N3LO chiral forces [PDF]

open access: yes, 2014
We solve three-nucleon Faddeev equations with nucleon-nucleon and three-nucleon forces derived consistently in the framework of chiral perturbation theory at next-to-next-to-next-to-leading order in the chiral expansion.

Hydration of NaDNA by neutron quasi-elastic scattering

open access: yesBiophysical Journal, 1988
Preliminary results of neutron quasi-elastic scattering experiments are reported for hydrated paracrystals of sodium deoxyribonucleic acid (NaDNA). The samples were investigated at two water contents: 3.5 +/- 1.0 and 9.5 +/- 1.5 mol H2O per mole nucleotide.

Resolution-elastic neutron scattering by correlation techniques

open access: yesJournal of Advanced Research, 2019
Neutron scattering applications often require discriminating the elastic contribution from the inelastic contribution. For this purpose, correlation spectroscopy offers an effective tool with both pulsed and continuous neutron sources as well as several ...

Large-angle scattering and quasi-elastic barrier distributions [PDF]

open access: yes, 2004
We study in detail the barrier distributions extracted from large-angle quasi-elastic scattering of heavy ions at energies near the Coulomb barrier. Using a closed-form expression for scattering from a single barrier, we compare the quasi-elastic barrier
