We studied the hydrogen absorption and desorption properties of thin Pd-covered Mg1−xAlx alloy films as a function temperature composition. Using neutron reflectometry, we were able to determine content distribution within these MgAl in situ. For all films, was uniformly dispersed film no observable Pd cover layer. The Mg0.7Al0.3 shows an appreciable 4.1wt% stored improved characteristics with complete at 448K.
The ready availability of codes such as LAMMPS (Large-scale Atomic/Molecular Massively Parallel Simulator) for molecular dynamics simulations has opened up the realm atomistic modelling to novice code users with an interest in computational materials but who lack appropriate theoretical or background. As such, there is significant risk “user effect” having a negative impact on quality results obtained using codes. Here, we present “how-to” procedure equilibrium dynamics-based nuclear fuel...
A polarizable interatomic potential is developed for atomistic simulations of molten MNO3 (M = Li, Na, K) salts. The parametrized using a force matching method relying on the adjustment parameters such that density functional theory generated forces, stress tensors, and dipole moments are reproduced. Simulations conducted new used to estimate physical melt, which then compared with available experimental results. average calculated densities NaNO3 KNO3 within 2% value temperature range...
We used polarized neutron reflectometry to determine the temperature dependence of magnetization thin AuFe films with 3% Fe concentration. performed measurements in a large magnetic field 6 T range from 295 2 K. For thickness 500 20 nm we observed Brillouin-type behavior K down 50 and constant about 0.9 micro(B) per atom below 30 However, for 10 thick film 1.3 These experiments are first show finite-size effect single spin-glass fields. Furthermore, ability measure deviation paramagnetic...
Inert matrix fuels (IMF) consist of transuranic elements (i.e., Pu, Am, Np, Cm) embedded in a neutron transparent (inert) and can be used to "burn up" (transmute) these current or Generation IV nuclear reactors. Yttria-stabilized zirconia has been extensively studied for IMF applications, but the low thermal conductivity this material limits its usefulness. Other stabilize cubic structure, fuel increased through use lighter stabilizing element. To end, series Nd(x)Sc(y)Zr(1-x-y)O(2-δ)...

Thoria–plutonia (ThO 2 –PuO ) pellets with a nominal composition of 9.0 wt% PuO were prepared using fabrication route similar to an industrial process for production urania–plutonia (UO mixed oxide fuel. The green fuel separated into batches and the sintering each batch was carried out under reducing atmosphere at 1820 °C or 1750 °C. distribution plutonium (Pu) in sintered investigated by electron probe microanalysis X-ray mapping quantitative point analyses. results show that pellet samples...
Abstract The thermal stability and local long‐range structures in the title series of materials (obtained by a coprecipitation method) are characterized powder XRD, SEM, X‐ray absorption spectroscopy.
We performed polarized neutron reflectometry (PNR) experiments on a 29 nm thick Au93Fe7 film. The measurements were done in temperature range from 300 K to 2 magnetic field up 6 T applied the sample's plane, at we took PNR data 11 T. magnetization as determined by can be described with Brillouin function 295 down 50 assuming moment of isolated Fe atoms, i.e. 4 |μB per atom.
