Corrosion of Roman copper alloy coins in changing and variable burial environments
We studied the corrosion of Roman copper alloy coins that experienced alternations or progressive changes in their burial environment. We used coins that were still embedded in soil or in a concretion selectedfrom three professional excataved sites - Berlicum and Krommenie in the

Design and performance of a novel neutron powder diffractometer
PEARL at TU Delft
The performance of the new neutron powder diffraction instrument PEARL that is installed at the research reactor of Delft University of Technology is reported. It is based on the optimization concepts developed by Cussen [Nucl. Instrum. Methods Phys. Res. Sect. A (2007), 583, 394

Structural and thermodynamic study of Cs<sub>3</sub>Na(MoO<sub>4</sub>)<sub>2</sub>
Margin to the safe operation of sodium cooled fast reactors
Neutron diffraction measurements of the double molybdate Cs3Na(MoO4)2 have been performed for the first time in this work and the crystal structure refined using the Rietveld method. The thermal expansion of this trigonal phase, in space group P3¯m1, measured using high temperatu

Thermodynamic study of Cs3Na(MoO4)2
Determination of the standard enthalpy of formation and standard entropy at 298.15 K
The enthalpy of formation at 298.15 K and low temperature heat capacity of Cs3Na(MoO4)2 have been measured for the first time in this work using solution calorimetry and thermal-relaxation calorimetry in the temperature range T = (1.9–299.6) K, respectively. The solution calorime

Structural and thermodynamic study of dicesium molybdate Cs<sub>2</sub>Mo<sub>2</sub>O<sub>7</sub>
Implications for fast neutron reactors
The structure of α-Cs2Mo2O7 (monoclinic in space group P21/c), which can form during irradiation in fast breeder reactors in the space between nuclear fuel and cladding, has been refined in this work at room temperature from neutron diffraction data. Furthermore, the compounds' t

Understanding the activation of ZSM-5 by phosphorus
Localizing phosphate groups in the pores of phosphate-stabilized ZSM-5
Fluid catalytic cracking (FCC) produces (the feedstock for) a major part of the world's fuels, as well as chemical building blocks for, for example, polymers, pharmaceuticals, and specialty materials. ZSM-5 is the active ingredient in propyleneselective FCC catalyst systems and i

Gamma sensitivity of a ZnS
Ag(6-LiF) wavelength shifting fiber neutron detector in mixed neutron-gamma fields
Gamma sensitivity of an ISIS linear position sensitive wavelength shifting fiber (WLSF) detector was evaluated at the Reactor Institute Delft (RID) using 60Co and 137Cs sources. The caveat of quoting gamma sensitivity of a detector in pure gamma fields is that detectors are never

Dynamical coupling of intrinsically disordered proteins and their hydration water
Comparison with folded soluble and membrane proteins
Hydration water is vital for various macromolecular biological activities, such as specific ligand recognition, enzyme activity, response to receptor binding, and energy transduction. Without hydration water, proteins would not fold correctly and would lack the conformational fle

Neutron Science in Europe
Strengthening world-class research and innovation delivering economic and societal impact
The evolution of metallurgy is a fundamental aspect related to the knowledge of the technological level of ancient civilizations, for which the information was mostly part of an oral tradition. The ancient, preserved artefacts are the only keepers of this long gone knowledge. Mos

Characterization and Chemical Performance Assessment of Cementitious Materials
In Relation to the Dutch Case of Geologic Disposal of Nuclear Waste
In this study, non-destructive methods are applied to quantify the influence of concrete degradation by geologic conditions on the ability to retain nuclear waste deep underground in The Netherlands. Nuclear reactors play an important role in all four scenarios of the recent repo

Study on the effects of Doping Argyrodite with LiCl and LiF
In a Solid State Lithium Ion Battery
Solid state lithium ion batteries are generally safer than liquid electrolytes. Li6PS5Cl is a promising electrolyte with an instability in the active material and electrolyte interphase which causes an increase in impedance and capacity loss.
Doping with stable salts of LiCl and
