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

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 scattering of slow-neutrons in water-alcohol solutions [PDF]

Nuclear Physics and Atomic Energy, 2010
Research of molecules dynamics of solutions "water - propyl alcohol" of different concentration at the temperature 281 K is conducted by the method of slow-neutron quasi-elastic scattering. There were experimentally exposed the feature of effective self-diffusion coefficient of molecules of the indicated solutions. Based on the time-scale hierarchy the

Quasielastic neutron scattering from two dimensional antiferromagnets at a finite temperature [PDF]

, 2010
We consider frequency dependence of the neutron scattering amplitude from a two-dimensional quantum antiferromagnet. It is well known that the long range order disappears at any finite temperature and hence the elastic neutron scattering Bragg peak is ...

Emergence of a Hidden Magnetic Phase in LaFe11.8Si1.2 Investigated by Inelastic Neutron Scattering as a Function of Magnetic Field and Temperature

Advanced Physics Research
The NaZn13 type itinerant magnet LaFe13−xSix has seen considerable interest due to its unique combination of large magnetocaloric effect and low hysteresis.

Quasielastic Neutron Scattering Reveals Anisotropic Water Transport in Smectite Thin Film

Advanced Materials Interfaces
Clay minerals exhibit complex interactions with water that critically influence their functional properties, yet the anisotropic nature of water dynamics in smectite thin films remains underexplored.

Hydration‐ and Temperature‐Dependent Rotational Dynamics and Water Diffusion in Nanocellulose

Small Structures
Nanocellulose is a promising alternative to fossil‐derived materials, but its development is hindered by a limited understanding of cellulose–water interactions.

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 ...

SHERPA: A Spectrometer with High Energy Resolution and Polarisation Analysis [PDF]

EPJ Web of Conferences, 2022
SHERPA is a proposed quasielastic neutron spectrometer with polarisation analysis, intended to replace the ageing Iris instrument at the ISIS neutron and muon source. In this paper we present a concept of the instrument along with Monte-Carlo simulations
