Comment on "Dynamics in an oil-continuous droplet microemulsion as seen by quasielastic scattering techniques" by T. Hellweg et al [PDF]

, 2001
It is shown that the interpretation of quasielastic scattering experiments on droplet microemulsions in the paper by T. Hellweg et al., Phys. Chem. Chem. Phys., 2000, 2, 5168, contains serious shortcomings and should be revised.

Improved effective momentum approximation for quasielastic (e,e') scattering off highly charged nuclei [PDF]

Europhys.Lett. 67 (2004) 753-759, 2004
We address the problem of including Coulomb distortion effects in inclusive quasielastic (e,e') reactions using an improved version of the effective momentum approximation. Arguments are given that a simple modification of the effective momentum approximation, which is no longer applicable in its original form in the case of highly charged nuclei ...

Superscaling of non-quasielastic electron-nucleus scattering [PDF]

Phys.Rev.C80:035504,2009, 2009
The present study is focused on the superscaling behavior of electron-nucleus cross sections in the region lying above the quasielastic peak, especially the region dominated by electroexcitation of the Delta. Non-quasielastic cross sections are obtained from all available high-quality data for Carbon 12 by subtracting effective quasielastic cross ...

Underlying Roles of Polyol Additives in Promoting CO₂ Capture in PEI/Silica Adsorbents. [PDF]

ChemSusChem
Poly(ethylenimine) (PEI) mixed with short‐chain poly(ethylene glycol) (PEG) additives and co‐impregnated to mesoporous SBA‐15 silica demonstrate enhanced CO2 capacities and uptake rates. Neutron scattering, solid‐state NMR, and molecular dynamics simulations reveal that favorable PEI distribution is crucial.

Accessing self-diffusion on nanosecond time and nanometre length scales with minute kinetic resolution. [PDF]

J Appl Crystallogr
A new analysis framework to treat quasi‐elastic neutron spectroscopy data recorded at discrete energy transfers has been developed. This new approach can be employed successfully for kinetic studies of diffusive dynamics.Neutron spectroscopy uniquely and non‐destructively accesses diffusive dynamics in soft and biological matter, including for instance

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
