QENS investigation of filled rubbers
Applied Physics A: Materials Science & Processing, 2002The polymer segmental dynamics is investigated in a series of silica-filled rubbers. The presence of inert fillers in polymers greatly affects the mechanical and physical performance of the final materials. For example, silica has been proposed as a reinforcing agent of elastomers in tire production.

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.

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),

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 and NMR Investigation of Reorientational Dynamics in C61H2
Journal of Physics and Chemistry of Solids, 1993The molecular dynamics of the dihydrofulleroid C61H2 [1] have been studied. Protonated and deuterated samples have been synthesized and characterized by 13C, 1H, 2H high resolution NMR, HPLC, TGA, DSC and mass spectrometry. The molecular dynamic has been studied by powder NMR, and Quasielastic Neutron Scattering.

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.

QENS from polymer aggregates in supercritical CO2
Physica B: Condensed Matter, 2000Abstract We report QENS measurements from PS-b-PFOA aggregates in supercritical CO2. Line shapes are dominated by localized diffusive modes and segmental dynamics of the anchored, finite-length PFOA chains. For Q⩽0.6 A−1, we obtain effective diffusion coefficients of ≅0.8 10−6 cm2/s.

QENS and PCS study of aqueous BSA–PEO `crowded’ solutions
Physica B: Condensed Matter, 2000Abstract In this contribution we report first results from a study of aqueous protein–polymer solutions using the complementary techniques of quasielastic neutron scattering (QENS) and photon correlation spectroscopy (PCS). A 15% solution of bovine serum albumin (BSA) without and with 10% PEO600 (polyethylene oxide, M w =600) is used as a model ...
