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.

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.

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.

A database of synthetic inelastic neutron scattering spectra from molecules and crystals

Scientific Data, 2023
Inelastic neutron scattering (INS) is a powerful tool to study the vibrational dynamics in a material. The analysis and interpretation of the INS spectra, however, are often nontrivial.

Integration of machine learning with neutron scattering for the Hamiltonian tuning of spin ice under pressure

Communications Materials, 2022
Designing and understanding quantum materials requires continuous feedback between experimental observations and theoretical modelling. Here, a machine learning scheme integrates experiments with theory and modelling on experimental timescales for ...
