Probing vibrational modes in silica glass using inelastic neutron scattering with mass contrast [PDF]

, 2010
The effective vibrational density of states (VDOS) has been derived from inelastic neutron-scattering data, for isotopically substituted Si O 18 2 and Si O 16 2 glasses, to gain information about the relative contribution to the Si and O partial VDOS ...

The measurement of self-diffusion coefficients in liquid metals with quasielastic neutron scattering

EPJ Web of Conferences, 2015
Quasielastic incoherent neutron scattering (QENS) has proven to be a versatile tool to study self diffusion of atoms in liquid metals. Here it is shown, that coherent contributions to the signal in the small q limit appear as a flat and energy ...

Encapsulation of paclitaxel into a bio-nanocomposite. a study combining inelastic neutron scattering to thermal analysis and infrared spectroscopy

, 2015
The anticancer drug paclitaxel was encapsulated into a bio-nanocomposite formed by magnetic nanoparticles, chitosan and apatite. The aim of this drug carrier is to provide a new perspective against breast cancer. The dynamics of the pure and encapsulated

Dynamics of ganglioside micellar solutions by quasielastic neutron scattering

, 2004
Gangliosides are double-tailed biological amphiphiles naturally abundant in the nervous system. We present a quasielastic neutron scattering study on the dynamics of ganglioside molecules in 15% concentration micellar solution.

Low-energy spin fluctuations in the non-Fermi-liquid compound YbRh2Si2

Science and Technology of Advanced Materials, 2007
We report on inelastic neutron scattering experiments on YbRh2Si2 powder to study the low-energy spin dynamics at temperatures between T=0.8 and 22 K. The low-energy magnetic response is quasielastic.

Phonon-Activated Collective Hopping in a Superionic Phase

Physical Review X
Superionic conductors are fascinating systems representing a state of matter intermediate between solids and liquids, yet their underlying physics remain poorly understood. Correlations in jump dynamics have been theoretically proposed as a key mechanism

Modulation of Protein Dynamics by Glycerol in Water-Soluble Chlorophyll-Binding Protein (WSCP)

Crystals
Proteins are inherently dynamic entities that rely on flexibility across multiple timescales to perform their biological functions. The surrounding environment plays a critical role in modulating protein dynamics by exerting plasticizing or stabilizing ...

Quasielastic and low-energy inelastic neutron scattering study of HoCrO 3 by high resolution time-of-flight neutron spectroscop

, 2017
In order to understand the origin of the huge quasielastic magnetic scattering observed previously with a back-scattering neutron spectrometer, we have re-investigated the low energy excitations in HoCrO3 by inelastic neutron scattering in a much wider ...
