Quasielastic Neutron Scattering Reveals Anisotropic Water Transport in Smectite Thin Film

Advanced Materials Interfaces
Clay minerals exhibit complex interactions with water that critically influence their functional properties, yet the anisotropic nature of water dynamics in smectite thin films remains underexplored.

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.

Effect of Halide Variations on Cation Dynamics in MAPbX₃ (X = Cl, Br, and I). [PDF]

Small
This study uncovers the pivotal role of halide composition in dictating MA cation dynamics in MAPbX3 (X = Cl, Br, and I). MAPbCl3 exhibits the earliest and broadest onset of threefold MA rotation with the lowest activation energy, driven by pronounced octahedral distortions and reduced steric hindrance from the smaller Cl⁻ ion.

Comparison of time-of-flight and MIEZE neutron spectroscopy of H₂O. [PDF]

J Appl Crystallogr
We report a comparison of modulation of intensity with zero effort (MIEZE), a neutron spin–echo technique, and neutron time‐of‐flight spectroscopy, a conventional neutron scattering method. The basis of this comparison is provided by measurements performed on pure water under the same measurement conditions.We report a comparison of modulation of ...

High Ionic Conduction in Rb- and Cs-Mixed Cation Amide for Energy Storage. [PDF]

Small
A mixed cation‐amide solid solution, Rb0.5Cs0.5NH2, based on the interaction between RbNH2‐ and CsNH2, has been developed. The Rb⁺/Cs⁺ cationic substitution leads to structural stabilization, resulting in high ionic conductivity in the Rb0.5Cs0.5NH2 compared to the single compounds.

Manipulation of Emergent Collective Excitations via Composition Control in Mixed MPX₃ Correlated 2D Antiferromagnets. [PDF]

Adv Sci (Weinh)
Transition metal and chalcogen substituents are introduced into 2D antiferromagnet, NiPS3, and comprehensive photoluminescence and Raman spectroscopy studies are conducted to investigate how spin orbit entangled exciton and two magnon scattering evolve as functions of substituent concentration.
