Quasi- and inelastic neutron scattering to investigate the molecular dynamics of discotic molecules in the bulk

EPJ Web of Conferences, 2015
In- and quasielastic neutron scattering is employed to investigate both the vibrational density of states and the molecular dynamics of two homologous discotic liquid crystals (DLC) with different length of the alkyl side chain based on a triphenylene ...

Rotation of complex ions with ninefold hydrogen coordination studied by quasielastic neutron scattering and first-principles molecular dynamics calculations

Physical Review Research, 2022
Quasielastic neutron scattering (QENS) and neutron powder diffraction of the complex transition metal hydrides Li_{5}MoH_{11} and Li_{6}NbH_{11} were measured in a temperature range of 10–300 K to study their structures and dynamics, especially the ...

Quasielastic and low-energy inelastic neutron scattering study of HoCrO 3 by high resolution time-of-flight neutron spectroscop [PDF]

, 2017
In order to understand the origin of the huge quasielastic magnetic scattering observed previously with a back-scattering neutron spectrometer, we have re-investigated the low energy excitations in HoCrO3 by inelastic neutron scattering in a much wider ...

Translational Dynamics of Imidazolium-Based Ionic Liquids in Acetonitrile Solutions

Liquids, 2023
The dynamics of pure ionic liquids and solutions with acetonitrile have been investigated through quasielastic neutron scattering (QENS). The translational diffusive motion of the 1-butyl-3-methyl-imidazolium cation was revealed as a function of ...

Halide Perovskite: A Rich Source of Thermal Insulator

Advanced Science, EarlyView.
Halide perovskites exhibit ultralow thermal conductivity driven by intrinsic lattice softness and strong anharmonicity, falling below conventional defect‐engineering limits. Weak metavalent bonding, A‐site rattling, and dynamic octahedral tilting drive phonon scattering to the Ioffe–Regel limit, where wave‐like tunneling replaces particle‐like ...

Decoupling Electronic Activation and Pore Connectivity in Acidic Oxygen Reduction on Metal‐Free Biomass‐Derived Carbon Catalysts

ChemElectroChem, Volume 13, Issue 16, 18 August 2026.
Acidic ORR on biomass‐derived carbon is described by partially separable electronic and transport contributions. Defect‐derived electronic states are associated with the onset region, whereas connected three‐dimensional pore pathways are associated with accessibility in the transport‐influenced regime.

Self-diffusion in liquid copper as seen by quasielastic neutron scattering [PDF]

, 2010
Quasielastic neutron scattering has been used to study atomic dynamics in liquid Cu. At small wave numbers q the intermediate scattering function is dominated by incoherent scattering contributions.
