Low-frequency excitations in glassy selenium: A comparison of neutron-scattering and molecular-dynamics results
(American Institute of Physics Publising LLC, 1993)
The microscopic low-frequency dynamics of glassy selenium is investigated by means of the concurrent use of neutron inelastic scattering and computer simulations. A separation of the dynamic response in terms of intra- and ...

Hydration properties of synthetic high-charge micas saturated with different cations: An experimental approach
(Walter de Gruyter, 2013)
An understanding of the interaction mechanisms between exchangeable cations and layered silicates is of interest from both a basic and an applied point of view. Among 2:1 phyllosilicates, a new family of swelling high-charge ...

Purely dynamical signature of the orientational glass transition
(American Physical Society, 1999-10-04)
The dynamics of the freezing transition of the rotator phase crystal of ethanol into its orientational glass phase is monitored by measurements of molecular rotational components in the quasielastic neutron scattering ...

Role of low-frequency vibrations on sound propagation in glasses at intermediate temperature
(American Physical Society, 2000)
We report measurements of the temperature dependence of the sound attenuation and the fractional change in sound velocity for the glass (G) and orientational-glass (OG) phases of polymorphic ethanol. Strikingly similar ...

N-acetyl-2,3,4,6-tetra-O-acetyl-N-benzyl-β-D-glucopyranosylamine
(International Union of Crystallography, 1997)
The solid-state conformation of the title compound, C23H29NOIo, has been unequivocally established. The configuration at C 1 is/3-D-glucopyranose and the pyranose ring is essentially a perfect chair. Only the E ...

Thermal transport in glassy selenium: The role of low-frequency librations
(American Institute of Physics Publising LLC, 1994)
The experimental curves giving the temperature dependence of the thermal conductivity of glassy selenium are considered in detail. The observed behavior can be taken into account quantitatively if the densities of states ...

Low-frequency excitations in a molecular glass: Single-particle dynamics
(American Institute of Physics Publising LLC, 1992)
The low-frequency dynamics of a molecular glass former has been investigated by means of inelastic neutron scattering from a mostly incoherent sample as well as by computer molecular-dynamics simulation. The mode assignments ...

Microscopic dynamics of glycerol in its crystalline and glassy states
(American Physical Society, 1996)
The dynamics of crystalline glycerol are studied by means of Raman spectroscopy and lattice dynamics calculations employing a semiflexible model to represent the low-lying molecular vibrations. The latter is validated ...

Correlated atomic motions in glassy selenium
(American Institute of Physics Publising LLC, 1994)
The elastic and total (energy-integrated) structure factors for glassy selenium have been measured by means of neutron spectroscopy within the temperature range 15 KT310 K. The correlated nature of the atomic vibrations ...
