QENS: A glimpse into the future
Neutron News, 1993Abstract There is a debate going on about the raison d'etre of large-scale central facilities. They serve a multiple role and attract an increasing number of scientists, wheth & for a single specific experiment or as part of a long term research program.

Before one can interpret quasi-elastic scattering data sets one first needs to appreciate the concepts that underpin the neutron method, and the themes that recur frequently in the scientific literature on neutron science. Using a predominantly semi-classical approach, this chapter builds a phenomenological understanding of ideas such as cross sections,

QENS study of trehalose/water/acrylamide–acrylic acid
Physica B: Condensed Matter, 2001Abstract This work reports quasi elastic neutron scattering (QENS) results on the trehalose/water/acrylamide–acrylic acid copolymer system, recently employed in agricultural chemistry. H/D substitution technique allows to separate the diffusive dynamics of trehalose from that of water.

Slow Dynamics in Liquid Metals as Seen by QENS
Zeitschrift für Physikalische Chemie, 2010Abstract The quasielastic dynamics in liquid metals has been investigated by neutron scattering extensively during the past years. Precise measurements of the self-particle dynamics and the coherent quasielastic response provided conclusive evidence that the relaxation dynamics is governed by at least two processes. These two time scales

Abstract The 4th International Workshop on Quasi–Elastic Neutron Scattering, QENS '98, was held in Nykoping, Sweden from August 6–8, 1998. Following the tradition of previous meetings, which were held on the grounds of Windsor Castle (UK), in apalace in San Sebastian (Spain) and in a converted farm house on the campus of the University of Parma (Italy),

Diffusion motions in hydrated sodium alginate by QENS
AIP Conference Proceedings, 2010QENS experiments are very suitable for the study of water‐polysaccharides systems both for slow polymer chains dynamics as well as for faster solvent molecules dynamics. By a suitable choice of experimental conditions as well as a properly data processing we can get information about the motion modes of various molecular groups of polymer chains in ...

Excess water dynamics in hydrotalcite: QENS study
Pramana, 2004Results of the quasi-elastic neutron scattering (QENS) measurements on the dynamics of excess water in hydrotalcite sample with varied content of excess water are reported. Translational motion of excess water can be best described by random translational jump diffusion model.

Dynamic scaling of QENS spectra of glassy water in aging cement paste
Physica A: Statistical Mechanics and its Applications, 2002Abstract We propose a new method for the analysis of high-resolution incoherent quasi-elastic neutron scattering spectra of water in porous media and apply it, in particular, to a case of water in hydrated tricalcium silicate. We plot the normalized frequency-dependent susceptibility as a function of a scaling variable ω/ωp, where ωp is the peak ...
