Correlation between hydrogen storage properties and textures induced in magnesium through ECAP and cold rolling
(Elsevier B.V., 2014-03-06)
It is feasible to obtain a significant enhancement of the hydrogen storage capability in magnesium by selecting an appropriate sequence of mechanical processing. the Mg metal may be produced with different textures which ...
A new model for the prediction of oxygen interference in hydrogen storage systems
(Pergamon-Elsevier Science Ltd., 2014-04)
A new model is developed to analyze oxygen interference in hydrogen storage materials. It is based on the competitive adsorption isotherm between the two gases, with the parameters fitted from molecular dynamic simulations. ...
Kinetics and hydrogen storage performance of Li-Mg-N-H systems doped with Al and AlCl3
(Elsevier Science Sa, 2018-10)
Recent investigations showed the formation of new amide-chloride phases between LiNH2 and AlCl3 after milling and/or heating under hydrogen pressure. These phases exhibited a key role in the improvement of the hydrogen ...
On the lattice dilation of palladium nanoparticles and a new methodology for the quantification of interstitials
(2021-11-10)
In contrast to the expected behavior for metallic nanoparticles (NPs) where a contraction of the lattice parameter occurs as the crystal size decreases, palladium NPs experience both lattice contraction and dilation. Such ...
Hydrogen absorption and desorption in the Mg-Ag system
(Elsevier Science Sa, 2014-05-22)
We analyze hydrogen absorption and desorption in Mg and Mg?Ag compounds prepared by mechanical milling. The materials were obtained by processing mixtures of Mg or MgH2 with different proportions of Ag under Ar or H2 ...
Probing the intra-group medium of a z=0.28 galaxy group
(OXFORD UNIV PRESS, 2017)
We present new MUSE observations of a galaxy group probed by a background quasar. The quasar sightline passes between multiple z = 0.28 galaxies, whilst showing at the same redshift low-ionized metal line species, including ...
Stress reduction in a hydride container by the addition of a glidant agent
(Pergamon-Elsevier Science Ltd, 2020-10-16)
Hydrogen absorbing materials, such as metal hydrides, present a possible solution for hydrogen storage. During the absorption process these materials swell, which can put the mechanical integrity of its container at risk. ...
