Disentangling Multiscale Cation–Anion Dynamics in Li4(BH4)(NH2)3 Using Quasielastic Neutron Scattering [PDF]

Small Science
Elucidating the interplay between anion dynamics and cation transport is essential for the rational design of solid‐state ionic conductors. Here, we investigate the relationship between local anion motion and long‐range Li+ transport in Li4(BH4)(NH2)3 by

Unravelling Electronic Structure and Molecular Vibrations of Proteins in Virus Using Novel Correlated Plasmon-Enhanced Raman Spectroscopy With Machine Learning. [PDF]

Small
A novel, non‐destructive, stable, direct technique, named correlated plasmon‐enhanced Raman spectroscopy (CP‐ERS), which is based on a newly‐developed highly oriented single crystalline gold quantum dots (HOSG‐QDs) chip, is developed to measure and quantify molecular vibrations and electronic structure of analytes.

Correlated Polymer-Proton Hopping Enables Water-Independent Fast Proton Transport in Poly(Ionic Liquid) Membranes. [PDF]

Adv Sci (Weinh)
A polymer chain in motion: backbone, ring, and counterion dynamics interlock across timescales to relay protons through poly(ionic liquid) membranes. ABSTRACT Polymer electrolyte membranes composed of ionic liquids (IL), capable of conducting protons efficiently at elevated temperatures, without external humidification, could transform fuel cell ...

Rational Design of Weakly-Solvating Molecules for Salt-In-Pre-Ionic-Liquid Electrolytes for Li Metal Batteries. [PDF]

Adv Sci (Weinh)
The weakly‐solvating TFMSPyr electrolyte tailors the Li+ solvation structure by suppressing solvent coordination and promoting anion‐dominated solvation. This unique solvation environment induces preferential anion decomposition at electrode interfaces, forming robust inorganic rich S/CEI.

How Proton Incorporation Reshapes Lattice Dynamics In BaSnO₃-Type Proton Conductors. [PDF]

Adv Sci (Weinh)
Yttrium‐doped BaSnO3 exhibits isotope‐dependent changes in its low‐energy vibrational density of states upon hydration. Comparison of dry, H2O‐, and D2O‐treated samples re‐veals mass‐dependent phonon renormalization linked to proton dynamics near oxygen va‐cancies, providing experimental insight into hydrogen‐coupled lattice excitations in proton ...

SHERPA: A Spectrometer with High Energy Resolution and Polarisation Analysis [PDF]

EPJ Web of Conferences, 2022
SHERPA is a proposed quasielastic neutron spectrometer with polarisation analysis, intended to replace the ageing Iris instrument at the ISIS neutron and muon source. In this paper we present a concept of the instrument along with Monte-Carlo simulations

The SuSA Model for Neutrino Oscillation Experiments: From Quasielastic Scattering to the Resonance Region

Universe, 2021
High-precision studies of Beyond-Standard-Model physics through accelerator-based neutrino oscillation experiments require a very accurate description of neutrino–nucleus cross-sections in a broad energy region, going from quasielastic scattering up to ...

Dynamics of water within Cu-loaded zeolites: A quasielastic neutron scattering study

Catalysis Communications, 2022
Quasielastic Neutron Scattering (QENS) was employed in order to probe the dynamics of water confined within copper-loaded MOR, MFI and CHA zeolite frameworks in the temperature range 100–300 K.
