Origin of dielectric relaxor behavior in PVDF-based copolymer and terpolymer films

AIP Advances, 2018
Relaxor ferroelectrics exhibit frequency-dispersion of their dielectric permittivity peak as a function of temperature, the origin of which has been widely debated. Microscopic understanding of such behavior for polymeric ferroelectrics has presented new

Diffusion in membranes: Toward a two-dimensional diffusion map

EPJ Web of Conferences, 2015
For decades, quasi-elastic neutron scattering has been the prime tool for studying molecular diffusion in membranes over relevant nanometer distances. These experiments are essential to our current understanding of molecular dynamics of lipids, proteins ...

Microscopic dynamics of glycerol: a QENS study

We report on a quasielastic incoherent neutron scattering (QENS) experiment onliquid glycerol. QENS data were collected at thetemperature T=380 K and witharesolution(FWHM)R=55µeV.The analysis of the quasielastic signal enables us to draw a ...

Perfluorinated surfactants as model charged systems for understanding the effect of confinement on proton transport and water mobility in fuel cell membranes. A study by QENS

, 2010
International audienceWe have investigated the dynamical properties of water confined in mesomorphous phases of perfluorinated sulfonic surfactants. These systems mimic the physico-chemical properties of the perfluorinated Nafion membranes which are used

Data Analysis for Time-Resolved QENS Experiments in Biophysics

, 2017
To study the correlation between internal protein dynamics and protein functionality of bacteriorhodopsin, we have performed time-resolved quasielastic neutron scattering (QENS) experiments combined with in situ laser activation of protein function.

The application of quasi-elastic neutron scattering techniques (QENS) in surface diffusion studies

, 2012
Neutron scattering techniques such as quasi-elastic neutron scattering, QENS, have proven to be well-suited tools for studying structure and dynamics of surface adsorbed molecules.

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 ...

Analysis of dislocation pipe diffusion in deformed alpha-phase PdHX using a synthesized QENS approach

, 2017
Using quasielastic neutron scattering results from multiple spectrometers, material considerations are made for annealed and deformed PdH_x with sufficiently low [H] as to encourage the process of dislocation pipe diffusion (DPD) below a critical ...
