Polaronic metal phases in La$_{0.7}$Sr$_{0.3}$MnO$_{3}$ uncovered by inelastic neutron and x-ray scattering

, 2015
Among colossal magnetoresistive manganites the prototypical ferromagnetic manganite La$_{0.7}$Sr$_{0.3}$MnO$_{3}$ has a relatively small magnetoresistance, and has been long assumed to have only weak electron-lattice coupling.

Probing Short Range Nucleon Correlations in High Energy Hard Quasielastic pd Reactions [PDF]

, 1994
We show that the strong dependence of the amplitude for $NN$ hard scattering on the collision energy can be used to magnify the effects of short range nucleon correlations in quasielastic $pd$ scattering.

QENS investigation of proton confined motions in hydrated perfluorinated sulfonic membranes and self-assembled surfactants

EPJ Web of Conferences, 2015
We report on QuasiElastic Neutron Scattering (QENS) investigations of the dynamics of protons and water molecules confined in nanostructured perfluorinated sulfonic acid (PFSA) materials, namely a commercial Aquivion membrane and the perfluorooctane ...

Dynamics of proteins with different molecular structures under solution condition

Scientific Reports, 2020
Incoherent quasielastic neutron scattering (iQENS) is a fascinating technique for investigating the internal dynamics of protein. However, low flux of neutron beam, low signal to noise ratio of QENS spectrometers and unavailability of well-established ...

How sensitive are protein hydration shells to electrolyte concentration and protein composition?

Protein Science, Volume 34, Issue 1, January 2025.
Abstract Proteins of obligate halophilic organisms have an unusually high number of acidic amino acids, thought to enable them to function in multimolar KCl environments. Clarifying the molecular scale mechanisms by which this occurs is relevant for biotechnology, to enable enzymatic synthesis of economically important small molecules in salty ...

Fast ionic mobility in cryolite studied by quasielastic neutron scattering [PDF]

Solid State Ionics, 2008
Abstract Quasielastic neutron scattering (QENS) has been used to study the relation between ionic mobility and conductivity at high temperature of the perovskite fluoride cryolite, Na3AlF6. Up to T = 880 °C the conductivity is dominated by jump diffusion of Na ions.

Momentum-space structure of quasielastic spin fluctuations in Ce3Pd20Si6

, 2014
Among heavy-fermion metals, Ce$_3$Pd$_{20}$Si$_6$ is one of the heaviest-electron systems known to date. Here we used high-resolution neutron spectroscopy to observe low-energy magnetic scattering from a single crystal of this compound in the ...

Uncorrelated and correlated nanoscale lattice distortions in the paramagnetic phase of magnetoresistive manganites [PDF]

, 2004
Neutron scattering measurements on a magnetoresistive manganite La$_{0.75}$(Ca$_{0.45}$Sr$_{0.55}$)$_{0.25}$MnO$_3$ show that uncorrelated dynamic polaronic lattice distortions are present in both the orthorhombic (O) and rhombohedral (R) paramagnetic ...

The functional role of protein dynamics in photosynthetic reaction centers investigated by elastic and quasielastic neutron scattering

EPJ Web of Conferences, 2015
This short review summarizes our current knowledge about the functional relevance of protein dynamics in photosynthetic reaction centers. In the case of Photosystem II membrane fragments, elastic and quasielastic neutron scattering experiments reveal a ...

Quasielastic Neutron Scattering Study on Polymer Nanocomposites

Journal of Physics: Conference Series, 2014
By using a quasielastic neutron scattering technique (disk-chopper-type spectrometer AMATERAS at J-PARC), we have investigated the microscopic dynamics of polybutadiene (PB) in which silica particles were embedded. The experimental results gave us both a damped vibration mode of PB and jumped diffusion motion of the segments.
