Materials Characterization, 2021
Abstract Cement hydration is a key process to determine most properties of cementitious materials. A deep understanding of cement hydration is thus favourable for the improvement of the overall properties of these materials and for providing solutions to the technique problems for concrete applications in terms of durability and sustainability.

Quasi-elastic (QENS) and inelastic neutron scattering (INS) on hexamethylbenzene
Physica B: Condensed Matter, 2005Abstract The Quasi-elastic Neutron scattering (QENS) spectra of polycrystalline hexamethylbenzene (HMB) were measured for temperatures from 10 K to room temperature (phase III and phase II) for momentum transfer 1.9 A −1 . The Inelastic Neutron scattering (INS) and QENS spectra for momentum transfer 0.5–2.9 A −1 were measured at T = 20 , 100 ...

Supercooled Water in PVA Matrixes: I. An Incoherent Quasi-Elastic Neutron Scattering (QENS) Study
The Journal of Physical Chemistry B, 2003The incoherent quasi-elastic neutron scattering study of poly(vinyl alcohol) based hydrogels was carried out to elucidate the dynamic state of water caged in polymeric matrixes with different degree of cross-linking and nature of the cross-linking agent.

The application of quasi-elastic neutron scattering techniques (QENS) in surface diffusion studies
The European Physical Journal Special Topics, 2012Neutron 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. In contrast to many more widely used surface science techniques neutron scattering allows the microscopic characterization of samples under a wide range of thermodynamic ...

The quasi-elastic neutron scattering (QENS) spectra over the temperature range 10–270 K were studied. The activation energies for the stochastic jumps of methyl groups in neat tetramethylpyrazine (TMP) and in the complex TMP·TCNB (tetracyanobenzene) were estimated to be equal to 5.0 ± 1.2 and 2.2 ± 1.1 kJ/mol, respectively, which means that the methyl ...

Background: Protein digestion under gastric conditions is influenced by the activity of the enzyme pepsin. With a limited penetration depth, pepsin-induced protein hydrolysis mainly occurs at the surface of the gel particles. Understanding the diffusion of digestive enzymes within different casein gels is a key factor to better control protein ...
