Very-large-area detector systems for low-energy-transfer time-of-flight spectrometers are discussed. Four different kinds of linear position-sensitive detector arrays with spherical- or cylindrical-zone geometries are considered. A non-uniform sample

Protein dynamics in hydrated and vacuum-dried photosystem II (PS II) membrane fragments from spinach has been investigated by quasielastic neutron scattering (QENS) in the temperature range between 5 and 300 K. Three distinct temperature ranges can b

Quasielastic neutron scattering and high-frequency (10 MHz to 60 GHz) conductivity measurements have been performed on the high-temperature phase of LiNaSO4, a typical representative of a group of simple inorganic salts exhibiting both fast-cation co

A set of quasielastic neutron scattering experiments on solid solutions of sodium orthophosphate and sodium sulfate is reported. These materials are not only fast-ion conductors in their high-temperature cubic phases but also show considerable dynami

Quasielastic neutron scattering has been used to investigate the dynamical behavior of H(2)O in water/tert-butyl alcohol solutions. The measurements were made at fixed temperature (293 K) as a function of tert-butyl alcohol molar fraction, x, in the

We present a detailed study of the local dynamics of short polyethylene (PE) chains using molecular dynamics (MD) simulations and quasi-elastic neutron scattering (QENS) data. QENS measurements were carried out on two samples having different chain l

Time-of-flight quasielastic neutron scattering experiments have been performed on solid solutions of Na2SO4 and Na3PO4 in order to examine the reorientational anion motion in the picosecond range. The obtained data were analysed on the basis of the Q

The role played by the solvation water molecules on the macroscopically observed sol-gel transition in lecithin/cyclohexane/water reverse micelles is investigated by quasielastic neutron scattering, dielectric relaxation arid conductivity measurement

The work reports quasielastic neutron scattering (QENS) results on aqueous solutions of trehalose, a biologically and biomedically important disaccharide. We collected data at the Berlin Neutron Scattering Center (BENSC) on α,α-trehalose deuterated
