Reinforcing Particle Architectural Stability of Li‐Rich Cathode With Enhanced Anionic Redox Reaction Reversibility

Angewandte Chemie, EarlyView.
In this work, we establish a direct correlation between internal compactness and particle architectural stability, identifying it as a key descriptor of cathode structural integrity. Simultaneously, the capacity contribution and compensation mechanism of ARR are resolved, revealing that the extent of irreversible capacity loss is governed by both the ...

Rapid and efficient hydrogen clathrate hydrate formation in confined nanospace

Nature Communications, 2022
Clathrate hydrates are crystalline solids physically resembling ice, in which small molecules (typically gases) are trapped inside cages of hydrogen bonded, frozen water molecules.

The Spallation Neutron Source project [PDF]

Proceedings of the 1999 Particle Accelerator Conference (Cat. No.99CH36366), 2003
The SNS is a "joint-venture" project of five DOE National Laboratories, aimed at building the world's most powerful accelerator-based pulse spallation source. At its planned 2 MW operation, it will produce neutron fluxes at least a factor of ten greater than Rutherford Appleton Laboratory's ISIS, currently the world's leading spallation source.

The Development and Application of Multi-Cell Elliptical Superconducting Cavity Pre-Tuning Equipment

Applied Sciences
Elliptical superconducting cavities are widely used in particle accelerators because they can provide stronger acceleration fields than regular cavities. Pre-tuning is required to improve their performance, but the process is time-consuming.

Fundamental neutron physics beamline at the spallation neutron source at ORNL [PDF]

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2015
We describe the Fundamental Neutron Physics Beamline (FnPB) facility located at the Spallation Neutron Source at Oak Ridge National Laboratory. The FnPB was designed for the conduct of experiments that investigate scientific issues in nuclear physics, particle physics, astrophysics and cosmology using a pulsed slow neutron beam.

Fundamental Neutron Physics at Spallation Sources

Annual Review of Nuclear and Particle Science, 2022
Low-energy neutrons have been a useful probe in fundamental physics studies for more than 70 years. With advances in accelerator technology, many new sources are spallation based. These new, high-flux facilities are becoming the sites for many next-generation fundamental neutron physics experiments.
