A high-resolution neutron diffraction and electron diffraction study of the structure and phase transitions in AgTaO3

APL Materials
The high temperature phase transition behavior of the quantum paraelectric material, AgTaO3, has previously been debated in the literature. To elucidate the phase transitions of AgTaO3, we used neutron powder diffraction and established the phase ...

Large Room Temperature Anomalous Nernst Effect Coupled with Topological Nernst Effect from Incommensurate Spin Structure in a Kagome Antiferromagnet

Advanced Science, EarlyView.
This study demonstrates that ErMn₆Sn₆, a kagome antiferromagnet hosting incommensurate spin textures, sustains finite scalar spin chirality that drives topological states. The anomalous Nernst effect (ANE) originates from the strong Berry curvature of Chern‐gapped Dirac fermions, while the topological Nernst effect (TNE) arises from emergent fields ...

Neutron Diffraction

, 2017
Neutron diffraction as an analytical tool in solid-state chemistry is briefly presented. We start by recalling a few characteristic properties of the neutron that make thermal neutrons a unique structural probe in solid-state science. The generation of neutrons, some fundamentals of neutron diffraction, concepts and components of instrumentation for ...

Vacancy‐Suppressed Garnet Electrolytes for Durable Solid‐State Batteries

Advanced Science, EarlyView.
A Li/O‐rich sintering strategy effectively suppresses intrinsic lithium and oxygen vacancies in cubic garnet electrolytes, yielding a dense and stable microstructure. The vacancy‐controlled electrolyte exhibits enhanced interfacial and air stability, enabling long‐term solid‐state battery cycling and providing a general design principle for defect ...

Boosting Fast‐Charging Performance of Ni‐Rich NCM9055 Cathodes with Nb2O5 Dual Functional Modification

Advanced Science, EarlyView.
A dual‐functional Nb2O5 modulation strategy is reported to overcome kinetic limitations in Ni‐rich cathodes. The formation of LiNbO3 phase at the grain boundary of the polycrystalline NCM9055 cathode preserves a radially aligned microstructure and establishes fast lithium‐ion pathways.

Critical remark on the FSDP-related correlations in chalcogenide glasses as treated in the paper [Alekberov RI, Isayev AI, Mekhtiyeva SI, Fábián M. Local structures and optical properties of As-Se-Te(S) chalcogenide glasses. Phys B: Condens Matter 2018; 550: 367–375]

Results in Physics, 2019
In the paper [Phys. B 550 (2018) 367–375], Alekberov, Isayev, Mekhtiyeva and Fábián have performed very erroneous calculation on diameter of voids responsible for the first sharp diffraction peak (FSDP) in neutron diffraction patterns of As2Se3-based ...

Tunable Negative Thermal Expansion in Fe/Cr‐Substituted Nd2Co17 Compounds via Magnetoelastic Coupling

Advanced Science, EarlyView.
This study achieves anisotropic thermal expansion tuning in Nd2(Co1‐xFex)17‐yCry compounds via a magnetoelastic strategy. Variable‐temperature synchrotron X‐ray diffraction reveals that increased Fe content induces switchable lattice responses. Compositional control reduces the volume expansion coefficient αV by 20% (x═0.7) and modulates TC (442–625 K),

Single Crystal Pulsed Neutron Diffraction [PDF]

Acta Crystallographica Section A Foundations of Crystallography, 1987
Diffraction data from single crystals is obtained using the white-beam, stationary crystal, Laue technique. Separation of orders of the same reflection, which therefore fall on the same spot on the detector, is by their different times of arrival. The geometry of diffraction, the resolution of time-of-flight (TOF) diffractometers and their design is ...

Lithiation‐Driven LiCrSe2 Shell Growth on Metallic CrSe2 Core Governs the Plateau–Slope Behavior

Advanced Science, EarlyView.
Layered CrSe2 is investigated as a lithium‐ion battery cathode combining fast Li+ diffusion and structural reversibility. Calculations and experiments reveal a single topotactic intercalation process with a characteristic plateau–slope profile governed by lithiation‐induced conductivity changes. A core‐shell lithiation evolution underpins its high‐rate
