Re-evaluation of protein neutron crystallography with and without X-ray/neutron joint refinement
IUCrJ, 2022 Protein neutron crystallography is a powerful technique to determine the positions of H atoms, providing crucial biochemical information such as the protonation states of catalytic groups and the geometry of hydrogen bonds.

Neutron Scattering as a Powerful Tool to Investigate Magnetic Shape Memory Alloys: A Review
Metals, 2021 Magnetic shape memory alloys (MSMAs) are an interesting class of smart materials characterized by undergoing macroscopic deformations upon the application of a pertinent stimulus: temperature, stress and/or external magnetic fields. Since the deformation

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1949 The problem of neutron diffraction by crystals is treated by analogy with X-ray diffraction, consideration being given to the perfect crystal, the mosaic crystal and the powdered block. The first part of the paper deals with a comparison between X-ray and neutron diffraction and it is shown that quantitatively the two are similar, apart ...

Accuracy of Measuring Rebar Strain in Concrete Using a Diffractometer for Residual Stress Analysis
Quantum Beam Science, 2023 Neutron diffraction is a noncontact method that can measure the rebar strain inside concrete. In this method, rebar strain and stress are calculated using the diffraction profile of neutrons irradiated during a specific time period.

Study of CeNi4Mn by neutron diffraction [PDF]
Solid State Communications, 2007 We report neutron diffraction measurements on CeNi4Mn, which has recently been identified as a soft ferromagnet (Tc ~ 140 K) with a sizeable spin-transport polarization. Our data show conclusively that the Mn atoms occupy a unique site (4c) in the unit cell, which has the symmetry of the cubic MgCu4Sn-type structure. We infer a moment of 4.6 mu_B on Mn
