The nature of magnetism in the cubic spinel Cr0.1Mn0.9Fe0.2Co1.8O4 is reported based onsystematic investigations by means of magnetization (M), ac susceptibility (χ) and heat capacity(CP) measurements, as well as by neutron diffraction. Structural characterization of the samplewas done using x-ray absorption spectroscopy, neutron and synchrotron diffraction. [...]

A large-area event-mode camera system coupled with a LiF-ZnS:Ag scintillator is applied for neutron resonance imaging (NRI) on the energy-resolved neutron imaging (ERNI) flight path, also known as Flight Path 5 (FP5), at the Los Alamos Neutron Science Center (LANSCE). This novel neutron imaging system, featuring a 120120 mm field of view, efficiently captures resonance information across the entire image in a single acquisition, significantly reducing beam time requirements compared to conventional energy-resolved neutron imaging systems. [...]

Time-of-flight neutron diffraction and energy-resolved imaging each provide unique perspectives into material properties. Neutron diffraction is useful for assessing microstructural parameters such as phase composition, texture, and dislocation densities, though it typically provides averaged data over the sampled volume.

This study investigates the impact of silicon content in the graphite anode of cylinder-type Li-ion batteries using operando neutron powder diffraction techniques. A batch of four different Li-ion cells is analyzed, with a focus on the structural response of active cell components during electrochemical cycling. [...]

o address challenges related to the intermittency of renewable energy sources, aqueous potassium-ion batteries (AKIBs) are a promising and sustainable alternative to conventional systems for large-scale energy storage. To enable their practical application, maximizing energy density and longevity while minimizing production and material costs is a key goal. [...]

Among Pb-free piezoelectrics, Na0.5Bi0.5TiO3 (NBT)-based ferroelectric systems have a unique distinction of offering a complex interplay of ferroelectric and nonferroelectric (in-phase octahedral tilt) structural instabilities, influencing its ferroelectric, dielectric, and electromechanical behavior. The morphotropic phase boundary (MPB) system like (1 – x)Na0.5Bi0.5TiO3-xK0.5Bi0.5TiO3 (NBT-KBT) is where this complexity plays out in full measure. [...]

Using high-pressure synchrotron X-ray diffraction combined with Raman spectroscopy and density-functional calculations, we determined the sequence of the pressure-induced transformations in CuReO4. At 1.5 GPa, the lattice symmetry changes from I41cd to I41/a with the transformation of isolated ReO4-tetrahedra into infinite chains of ReO6-octahedra. [...]

Achieving high ionic conductivities in solid state electrolytes is crucial for the development of efficient all-solid-state-batteries. Considering future availability and sustainability, sodium materials hold promises for an alternative for lithium materials in all-solid-state batteries, due to the higher abundance. [...]
