Quasielastic neutron scattering in soft matter

Current Opinion in Colloid & Interface Science, 2009
The general trend in soft matter is to study systems of increasing complexity which are more technologically and biologically relevant. This is facilitated by the capability of quasielastic neutron scattering (QENS) to selectively probe spatially resolved dynamical modes at a molecular level.

Asymptotic analysis of quasielastic neutron scattering data from human acetylcholinesterase reveals subtle dynamical changes upon ligand binding.

Journal of Chemical Physics, 2019
In this paper, we show that subtle changes in the internal dynamics of human acetylcholinesterase upon ligand binding can be extracted from quasielastic neutron scattering data by employing a nonexponential relaxation model for the intermediate ...

Study of the water dynamics near hydrophilic, nanostructured CuO surfaces by quasielastic and inelastic neutron scattering

AIP Advances, 2022
We have used quasielastic and inelastic neutron scattering to investigate the structure, dynamics, and phase transitions of water interacting with superhydrophilic CuO surfaces that not only possess a strong affinity for water but also a “grass-like ...

Achieving nanosecond time resolution with a two-dimensional X-ray detector. [PDF]

J Synchrotron Radiat
A proof‐of‐principle of a nanosecond time‐resolved experiment is demonstrated using a TEMPUS detector. The concept exploits an event driven mode of the detector and cross‐correlation analysis to overcome pixel dead time, and offers new opportunities for time‐resolved studies.The fastest pixel array X‐ray detectors can record images with nanosecond ...

Barrier distribution from 28Si+154Sm quasielastic scattering: Coupling effects in the fusion process

EPJ Web of Conferences, 2016
Barrier distribution for the 28Si+154Sm system has been extracted from large angle quasielastic scattering measurement to investigate the role of various channel couplings on fusion dynamics.

Neutron scattering study of magnetic ordering and excitations in the ternary rare-earth diborocarbide Ce^{11}B_2C_2 [PDF]

, 2007
Neutron scattering experiments have been performed on the ternary rare-earth diborocarbide Ce$^{11}$B$_2$C$_2$. The powder diffraction experiment confirms formation of a long-range magnetic order at $T_{\rm N} = 7.3$ K, where a sinusoidally modulated ...

Quasielastic neutron scattering experiment on water using TOFLAR (Time Of Flight and LARmor precession) technique at SNS

EPJ Web of Conferences, 2015
We present the results of the first TOFLAR (Time Of Flight and LARmor precession) experiment with a Larmor modulation device positioned after the sample. Using a setup based on the configuration of the SNS-NSE spectrometer (Spallation Neutron Source, USA)

Microscopic structure and dynamics of glass forming Zr2Co melts and the impact of different late transition metals on the melt properties

Journal of Non-Crystalline Solids: X, 2022
We studied the short-range order and the atomic dynamics of stable and undercooled binary Zr2Co alloy melts as well as their density and viscosity. The containerless processing technique of electrostatic levitation was used to achieve deep undercooling ...
