Structure‐Function Integration in 2D Hybrid Perovskite for Fast Neutron and Gamma Ray Discrimination

Advanced Science, EarlyView.
Using an in situ seed‐assisted cooling method, large (28 × 7 × 3 mm3) (GABA)2PbBr4 single crystals are grown, featuring hydrogen‐rich organic layers and a dense PbBr4 framework. This architecture enables efficient γ‐ray absorption, fast‐neutron sensitivity, and clear n/γ pulse‐shape discrimination (FOM up to 1.74), highlighting its potential as a ...

Air-heated solid–gas reaction setup for in situ neutron powder diffraction [PDF]

Journal of Applied Crystallography, 2019
The design and function of a reduction furnace, specially designed for solid–gas in situ monochromatic angular dispersive neutron powder diffraction, is presented. The functionality is demonstrated by performing a reduction experiment of CoFe2O4 nanoparticles at the instrument DMC at SINQ. Heating is provided by an air gun, allowing the sample to reach

Neutron scattering measurements of phonons in nickel at elevated temperatures [PDF]

, 2007
Measurements of elastic and inelastic neutron scatterings from elemental nickel were made at 10, 300, 575, 875, and 1275 K. The phonon densities of states (DOSs) were calculated from the inelastic scattering and were fit with Born–von Kármán models of ...

Room‐Temperature Magnetic Skyrmions and Intrinsic Anomalous Hall Effect in a Nodal‐Line Kagomé Ferromagnet MnRhP

Advanced Science, EarlyView.
MnRhP has been identified as a novel kagomé magnet that hosts magnetic skyrmions above room temperature and exhibits a large intrinsic anomalous Hall effect. The latter originates from Berry curvature associated with gapped nodal lines, establishing MnRhP as a promising platform for exploring high‐temperature topological phenomena in both real and ...

Hydrogen Absorption in Metal Thin Films and Heterostructures Investigated in Situ with Neutron and X-ray Scattering

Metals, 2016
Due to hydrogen possessing a relatively large neutron scattering length, hydrogen absorption and desorption behaviors in metal thin films can straightforwardly be investigated by neutron reflectometry. However, to further elucidate the chemical structure

A large volume cell for in situ neutron diffraction studies of hydrothermal crystallizations [PDF]

Review of Scientific Instruments, 2010
A hydrothermal cell with 320 ml internal volume has been designed and constructed for in situ neutron diffraction studies of hydrothermal crystallizations. The cell design adopts a dumbbell configuration assembled with standard commercial stainless steel components and a zero-scattering Ti–Zr alloy sample compartment.

Influence of Hydrogen‐Incorporation on the Bulk Electronic Structure and Chemical Bonding in Palladium

Advanced Science, EarlyView.
Hydrogen incorporation in palladium is directly probed using in situ ambient‐pressure hard X‐ray photoelectron spectroscopy under realistic, application‐relevant conditions. Correlated structural, spectroscopic, and theoretical analysis reveals how hydrogen loading modifies structure, electronic structure, and metal‐hydrogen bonding, resolving long ...

Transition Metal Compounds for Aqueous Ammonium‐Ion Batteries: Storage Mechanisms and Electrode Design

Advanced Science, EarlyView.
Aqueous ammonium‐ion batteries leverage hydrogen‐bond‐mediated NH4+ storage in tunable transition metal compounds. Despite progress in Mn‐, V‐, Mo‐, and W‐based compounds, 2D LDHs, and MXenes, challenges like structural instability and slow kinetics persist. Future advances require robust host design, mechanistic understanding via operando studies, and
