Integrated edge-to-exascale workflow for real-time steering in neutron scattering experiments [PDF]

Structural Dynamics
We introduce a computational framework that integrates artificial intelligence (AI), machine learning, and high-performance computing to enable real-time steering of neutron scattering experiments using an edge-to-exascale workflow.

Neutron scattering and neural-network quantum molecular dynamics investigation of the vibrations of ammonia along the solid-to-liquid transition [PDF]

Nature Communications
Vibrational spectroscopy allows us to understand complex physical and chemical interactions of molecular crystals and liquids such as ammonia, which has recently emerged as a strong hydrogen fuel candidate to support a sustainable society.

Determining the relaxation time from a temperature-dependent scan of the neutron spin-echo signal amplitude [PDF]

EPJ Web of Conferences, 2022
Temperature-dependent scans of the neutron scattering intensity are commonly employed in high energy-resolution quasielastic measurements. Besides serving as a useful diagnostic tool for identifying the temperature range that could give rise to a ...

The high-Q static scattering of 3-methyl pyridine/D2O mixtures without and with antagonistic salt [PDF]

EPJ Web of Conferences, 2023
Here we focus on the high-Q small-angle neutron scattering where we observed deviations from an ideal power law Q−2. From theory, this deviation Δ arises from the critical correlation-function exponent ηd in d dimensions.

Accurate Determination of the Neutron Skin Thickness of ^{208}Pb through Parity-Violation in Electron Scattering.

Physical Review Letters, 2021
We report a precision measurement of the parity-violating asymmetry A_{PV} in the elastic scattering of longitudinally polarized electrons from ^{208}Pb.

Advancing neutron diffraction for accurate structural measurement of light elements at megabar pressures

Scientific Reports, 2023
Over the last 60 years, the diamond anvil cell (DAC) has emerged as the tool of choice in high pressure science because materials can be studied at megabar pressures using X-ray and spectroscopic probes.

The Scattering of Neutrons by Protons [PDF]

Proceedings of the Royal Society of London. Series A - Mathematical and Physical Sciences, 1935
1. The mass defects of the lightest nuclei, particularly the ratio between that of the diplon and the α -particle, make it very probable that the range of the interaction force between proton and neutron is very small, of the order of about 10- 13 cm.

Mapping periplasmic binding protein oligosaccharide recognition with neutron crystallography

Scientific Reports, 2022
Numerous studies have shown how periplasmic binding proteins (PBPs) bind substrates with exquisite specificity, even distinguishing between sugar epimers and anomers, or structurally similar ions.
