Dynamics studied by Quasielastic Neutron Scattering (QENS) [PDF]
Adsorption, 2021 AbstractQuasielastic neutron scattering (QENS) allows measurement of the molecular displacements in time and space, from pico- to tens of nanoseconds and from Ångstroms to nanometers, respectively. The method probes dynamics from fast vibrational modes down to slow diffusive motion.

A modern approach to QENS data analysis in Mantid [PDF]
Physica B: Condensed Matter, 2019 Abstract Data analysis of Quasi-elastic Neutron Scattering (QENS) experiments often requires multiple steps involving fitting the elastic and quasi-elastic parts of spectra with several empirical functions and analytical models. Parameters of those models can be interdependent and also dependent on the momentum transfer vector Q.

Notes on Fitting and Analysis Frameworks for QENS Spectra of (Soft) Colloid Suspensions [PDF]
EPJ Web of Conferences, 2022 With continuously improving signal-to-noise ratios, a statistically sound analysis of quasi-elastic neutron scattering (QENS) spectra requires to fit increasingly complex models which poses several challenges.

Microscopic dynamics of glycerol: a QENS study
Journal of Physics: Conference Series, 2014 We report on a quasielastic incoherent neutron scattering (QENS) experiment onliquid glycerol. QENS data were collected at thetemperature T=380 K and witharesolution(FWHM)R=55µeV.The analysis of the quasielastic signal enables us to draw a consistentpicture of the diffusive mechanism on a picosecond time scale and to compare with most recentmodels for ...

Dynamics in Biological Systems as seen by QENS [PDF]
Zeitschrift Fur Physikalische Chemie, 2010 Abstract Quasielastic incoherent neutron scattering is a well suited and established experimental method to study protein and water dynamics in the picosecond to nanosecond time- and Ångstrom length-scale. Using deuterium labelling either protein or water motions can be selected and brought into focus.

Lattice-driven gating in a Cu-based zeolitic imidazolate framework for efficient high-temperature hydrogen isotope separation [PDF]
Nature CommunicationsFor the separation of hydrogen isotopes (H2/D2), traditional kinetic quantum sieving (KQS) takes advantage of the diffusion barriers created by the flexibility of organic linkers and the breathing frameworks in porous solids.

Quasi Elastic Neutron Scattering model library [PDF]
EPJ Web of Conferences, 2023 This paper reports on the development of a collection of dynamical models of one-dimensional peak profile functions used to fit dynamic structure factors S (Q, ħω) of Quasi Elastic Neutron Scattering (QENS) data.

Impact of composition on the crystal texture and on the dynamics of P(THF-co-ECH) copolymers [PDF]
EPJ Web of Conferences, 2022 We present a combined study by quasielastic neutron scattering (QENS), differential scanning calorimetry (DSC) and wide angle X-ray scattering (WAXS) on poly(tetrahydrofuran-co-epichlorohydrin) copolymers, to see how their composition can be used to tune
