Dynamics of Nanostructures for Drug Delivery: the Potential of QENS
Zeitschrift Fur Physikalische Chemie, 2010Abstract In recent biomedical studies different nanocarrier systems have been proposed for ´smart´ drug delivery. The engineering of these systems requires as a prerequisite a detailed knowledge of their structure and dynamics at the molecular level.

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 ...

Water dynamics in Na zeolite P by QENS
Physica B: Condensed Matter, 1997Abstract Quasi-elastic neutron-scattering (QENS) measurements have been made using the IRIS spectrometer (ISIS, UK) on water in synthetic Na zeolite P. The quasi-elastic broadening observed is assigned to a rotation of the water molecules.

Diffusive dynamics in trehalose aqueous solutions by QENS
Physica B: Condensed Matter, 2000Abstract The work reports preliminary QENS results on aqueous solutions of trehalose. The employment of H/D substitution allows the separation of the diffusive dynamics of water from that of trehalose. The data analysis shows a slowed down water dynamics in comparison to that of bulk water.

QENS and quasielastic Mössbauer spectroscopy for studying diffusion
Physica B: Condensed Matter, 1996QENS and quasielastic Mossbauer spectroscopy (QMS) are closely related in that both measure the double Fourier transform S(Q, ω) of the self-correlation function, which they deduce from scattering (QENS) and from resonant emission or absorption of nuclear γ radiation (QMS).

QENS investigation of the dynamics of starch saccharides
Physical Chemistry Chemical Physics, 2005We present here quasi-elastic neutron scattering results on D20 hydrated samples of amylose, one of the main saccharide components of starch. Two different sample hydrations (h = 0.5 and 1.0 g D2O (g dry amylose)-1 have been investigated in the temperature range 170 to 350 K.

Analysis of QENS in aligned nematic phases
Physica Scripta, 1995The potential of QENS (quasi-elastic neutron scattering) to study molecular diffusive motions is well established, but in nematic phases it has not measured up to expectations due to the complexities of such systems. In this work we report the results of a detailed analysis of QENS data obtained for partially deuterated ethoxybenzylidene-bis ...

Neutron News, 1994
Abstract The Quasielastic Neutron Scattering workshop, held at Miramar Palace, San Sebastian, Basque Country (Spain) on September 26–28, 1993, was a natural continuation of the series started at Cumberland Lodge, Windsor, UK in 1992. There it was decided to establish periodic discussion forums to maintain the community in close contact during these ...
