QENS and NMR Study of Water Dynamics in SBA-15 with a Low Water Content

, 2015
In this study, motions performed by water molecules adsorbed on the silica surface of SBA-15 material with 6.1% of water content (15% of pore filling) were investigated using NMR and Quasielastic Neutron Scattering (QENS) techniques.

Characterization of Bubbles and Antibubbles Interfaces Stabilized Using Pickering Particles With Different Wetting Properties

European Journal of Lipid Science and Technology, Volume 127, Issue 12, December 2025.
GRAPHICAL ABSTRACT Preparation of W/O/W double emulsions using hydrophobic silica (R972) and maltodextrin. A primary W/O emulsion is formed via homogenization and ultrasound and then re‐emulsified in an outer aqueous phase. The final emulsion is freeze‐dried for 1 day to obtain structured antibubbles.

QENS from polymeric micelles in supercritical CO₂

, 2000
We report QENS measurements from PS-b-PFOA aggregates in supercritical CO2. These consist of dense cores of CO2-insoluble polystyrene surrounded by a `corona' of PFOA surfactant molecules whose CO2-philic groups interface with supercritical CO2 ...

QENS and FTIR studies on binding states of benzene molecules adsorbed in zeolite HZSM-5 at room temperature [PDF]

, 2001
Fourier-transform infrared (FTIR) spectroscopy and quasi-elastic neutron scattering (QENS) were employed for monitoring of the binding states of benzene molecules, adsorbed in HZSM-5 zeolite at 300 K and for loadings of 0.6 to 7 molecules per ...

Diffusion of CH₄, CO₂, and Their Mixtures in AlPO₄‑5 Investigated by QENS Experiments and MD Simulations

, 2016
Quasi-elastic neutron scattering (QENS) measurements in combination with molecular dynamics (MD) simulations have been performed to characterize the dynamics of CH4, CO2, and binary mixtures of different compositions in the zeolite-type AlPO4-5 material.

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.

Molecular Dynamics of POPC Phospholipid Bilayers through the Gel to Fluid Phase Transition: An Incoherent Quasi-Elastic Neutron Scattering Study

Journal of Chemistry, 2017
The microscopic dynamics for the gel and liquid-crystalline phase of highly aligned D2O-hydrated bilayers of 1-palmitoyl-oleoyl-sn-glycero-phosphocholine (POPC) were investigated in the temperature range from 248 to 273 K by using incoherent quasi ...

Molecular-Dynamics Simulation of Self-Diffusion of Molecular Hydrogen in X-Type Zeolite

Journal of Chemistry, 2013
The self-diffusion of hydrogen in NaX zeolite has been studied by molecular-dynamics simulations for various temperatures and pressures. The results indicate that in the temperature range of 77–293 K and the pressure range of 10–2700 kPa, the self ...

Dynamic heterogeneity in polymer electrolytes. Comparison between QENS data and MD simulations

, 2001
We have investigated the dynamics of poly(ethylene oxide) (PEO) lithium-based salt electrolytes (PEO-LiBETI) using quasi-elastic neutron scattering (QENS). Measurements were carried out on the spectrometer NEAT (HMI, Berlin) above the melting temperature
