Disordered Rocksalts as High‐Energy and Earth‐Abundant Li‐Ion Cathodes

Advanced Materials, EarlyView.
Disordered rocksalts with lithium excess (DRX) offer a new direction in Li‐ion cathode design beyond conventional Ni‐ and Co‐based materials. This review highlights the design principles, synthesis strategies, and performance optimization of DRX oxides and oxyfluorides for energy‐dense, sustainable batteries using Earth‐abundant transition metals and ...

Inelastic neutron scattering applied to the investigation of collective excitations in topologically disordered matter

Condensed Matter Physics, 2008
Inelastic neutron scattering techniques are introduced here as one of the most important experimental techniques in the investigation of collective excitations in fluids (liquids and compressed gases) and amorphous solids.

Single Crystal Diffuse Neutron Scattering

Quantum Beam Science, 2018
Diffuse neutron scattering has become a valuable tool for investigating local structure in materials ranging from organic molecular crystals containing only light atoms to piezo-ceramics that frequently contain heavy elements.

Neutron spin echo spectroscopy with a moving sample

Scientific Reports, 2023
Neutron spin echo spectroscopy is a high resolution inelastic neutron scattering method probing nanosecond dynamics. It is well suited to study the atomistic motion in polymer systems and contributes to our understanding of viscoelasticity.

Synthesis of Primary Amines via Reductive Amination of Aldehydes and Ketones Over a Ni‐Doped MFM‐300(Cr) Catalyst

Advanced Science, EarlyView.
Reductive amination of aldehydes and ketones to primary amines with high selectivity and yield can be achieved over Ni‐doped MFM‐300(Cr) in the presence of NH3 and H2. In situ inelastic neutron scattering, coupled with modeling, reveals that cooperativity between Ni active sites and MFM‐300(Cr) affords an optimal microenvironment for the selective ...

Inelastic Scattering of Neutrons by Rotational Excitation [PDF]

Progress of Theoretical Physics, 1955
The collective nuclear model of A. Bohr is applied to the interpretation of inelastic scattering of neutrons, as was briefly described in our previous report6l. The present paper deals with the detailed theory of the inelastic scattering of neutrons by a direct excitation of the nuclear surface rctation, as well as by the resonance scattering via ...

Flash Synthesis of High‐Performance Sub‐Micron Low‐Disorder LiNixCoyAlzO2 Cathode Single Crystals

Advanced Energy and Sustainability Research, EarlyView.
A novel and scalable Flash‐Heat and Quench methodology has been developed to synthesize high‐performance LiNi0.8Co0.15Al0.05O2 single crystal cathodes in just minutes versus conventional methods that take multiple hours. X‐ray powder diffraction, neutron powder diffraction, and pair‐distribution and X‐ray absorption spectroscopy have shown low paired ...

Vibrational Spectroscopy of Tungsten(VI) Chlorides: WCl6 and WOCl4

ChemistryOpen, EarlyView.
WCL6 (left) and WOCl4 (right) are used for a variety of processes. Complete vibrational assignments are provided for both molecules as isolated systems and in the solid state. The assignments are based on new infrared, Raman, and the first inelastic neutron scattering spectra, supported by density functional theory calculations.

Phase transitions and spin dynamics of the quasi-one dimensional Ising-like antiferromagnet BaCo_{2}V_{2}O_{8} in a longitudinal magnetic field

Physical Review Research, 2023
By combining inelastic neutron scattering and numerical simulations, we study the quasi-one-dimensional Ising-like quantum antiferromagnet BaCo_{2}V_{2}O_{8} in a longitudinal magnetic field applied along the Ising anisotropy, which is also the chain ...
