Emergence of a Hidden Magnetic Phase in LaFe11.8Si1.2 Investigated by Inelastic Neutron Scattering as a Function of Magnetic Field and Temperature

Advanced Physics Research
The NaZn13 type itinerant magnet LaFe13−xSix has seen considerable interest due to its unique combination of large magnetocaloric effect and low hysteresis.

Effect of Halide Variations on Cation Dynamics in MAPbX₃ (X = Cl, Br, and I). [PDF]

Small
This study uncovers the pivotal role of halide composition in dictating MA cation dynamics in MAPbX3 (X = Cl, Br, and I). MAPbCl3 exhibits the earliest and broadest onset of threefold MA rotation with the lowest activation energy, driven by pronounced octahedral distortions and reduced steric hindrance from the smaller Cl⁻ ion.

Comparison of time-of-flight and MIEZE neutron spectroscopy of H₂O. [PDF]

J Appl Crystallogr
We report a comparison of modulation of intensity with zero effort (MIEZE), a neutron spin–echo technique, and neutron time‐of‐flight spectroscopy, a conventional neutron scattering method. The basis of this comparison is provided by measurements performed on pure water under the same measurement conditions.We report a comparison of modulation of ...

High Ionic Conduction in Rb- and Cs-Mixed Cation Amide for Energy Storage. [PDF]

Small
A mixed cation‐amide solid solution, Rb0.5Cs0.5NH2, based on the interaction between RbNH2‐ and CsNH2, has been developed. The Rb⁺/Cs⁺ cationic substitution leads to structural stabilization, resulting in high ionic conductivity in the Rb0.5Cs0.5NH2 compared to the single compounds.

Achieving nanosecond time resolution with a two-dimensional X-ray detector. [PDF]

J Synchrotron Radiat
A proof‐of‐principle of a nanosecond time‐resolved experiment is demonstrated using a TEMPUS detector. The concept exploits an event driven mode of the detector and cross‐correlation analysis to overcome pixel dead time, and offers new opportunities for time‐resolved studies.The fastest pixel array X‐ray detectors can record images with nanosecond ...

Moisture-Dependent Vibrational Dynamics and Phonon Transport in Nanocellulose Materials. [PDF]

Adv Mater
Uptake of water in cellulose play an important role in modulating the structure and phonon transport. This study reports how moisture‐dependent structural modification relates to the vibrational dynamics and phonon transport and scattering of nanocellulose using inelastic neutron scattering and wide angle X‐ray scattering.

Impact of composition on the crystal texture and on the dynamics of P(THF-co-ECH) copolymers [PDF]

EPJ Web of Conferences, 2022
We present a combined study by quasielastic neutron scattering (QENS), differential scanning calorimetry (DSC) and wide angle X-ray scattering (WAXS) on poly(tetrahydrofuran-co-epichlorohydrin) copolymers, to see how their composition can be used to tune

Quasielastic Scattering at MiniBooNE Energies [PDF]

AIP Conference Proceedings, 2009
We present our description of neutrino induced charged current quasielastic scattering (CCQE) in nuclei at energies relevant for the MiniBooNE experiment. In our framework, the nucleons, with initial momentum distributions according to the Local Fermi Gas model, move in a density- and momentum-dependent mean field potential.

Scattering of the halo nucleus 11Be from a lead target at 3.5 times the Coulomb barrier energy

Physics Letters B, 2020
Angular distributions of quasielastic scattering and breakup of the neutron-rich halo nucleus 11Be on a 208Pb target at an incident energy of 140 MeV (about 3.5 times the Coulomb barrier) were measured at HIRFL-RIBLL.

Dynamics–Function Correlation in Photosystem II: Molecular Dynamics in Solution

Crystals, 2023
A detailed comprehension of protein function requires information on the spatial structure of the protein, which is often gathered from X-ray crystallography.
