Dynamic Covalent Networks of Molecular Clusters for Hard and Impact‐Resistant Glass with Feasible Processability

open access: yesAdvanced Science, EarlyView.
Molecular granular material glass is fabricated by crosslinking sub‐nm POSS clusters with dynamic borate ester bonding while the materials combine high transparency, modulus, and hardness with superior impact resistance and (re)processability, offering a promising strategy for creating robust yet highly processable organic glasses.

Fundamental Neutron Physics at Spallation Sources

open access: yesAnnual 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.

Pressure‐Induced Structural and Magnetic Evolution in Layered Antiferromagnet YbMn2Sb2

open access: yesAdvanced Electronic Materials, EarlyView.
Pressure tunes the delicate balance between structure, magnetism, and electronic states in quantum materials. In YbMn2Sb2, high‐pressure X‐ray and neutron diffraction reveal a trigonal‐to‐monoclinic transition near 3.5 GPa, accompanied by unconventional magnetic ordering.

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

open access: yesAPL 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 ...

Facility for fast neutron irradiation tests of electronics at the ISIS spallation neutron source [PDF]

open access: yes, 2008
The VESUVIO beam line at the ISIS spallation neutron source was set up for neutron irradiation tests in the neutron energy range above 10 MeV. The neutron flux and energy spectrum were shown, in benchmark activation measurements, to provide a neutron ...

COHERENT at the Spallation Neutron Source

open access: yesAnnual Review of Nuclear and Particle Science, 2023
The Spallation Neutron Source (SNS) at Oak Ridge National Laboratory provides an intense, high-quality source of neutrinos from pion decay at rest. This source was recently used for the first measurements of coherent elastic neutrino–nucleus scattering (CEvNS) by the COHERENT Collaboration, which resulted in new constraints of physics beyond the ...

Quantum refinement with electron diffraction and X‐ray free‐electron laser data: comparative study of ribonucleotide reductase dimetal site

open access: yesJournal of Applied Crystallography, EarlyView.
For the first time quantum refinement has been performed with X‐ray free‐electron laser and microcrystal electron diffraction data for the dinuclear iron site in the R2a protein of ribonucleotide reductase. The method is shown to work well and can be used to determine the protonation state of the bridging solvent molecule and deduce photoreduction in ...
