“…[8±11,28] In the absence of a catalytic layer, the hydrogen loading is only possible at higher temperatures. [41,42] High temperature provides the molecules with the energy required to overcome the activation barrier. These results show that the nanoparticulate nature of the film has a strong influence on the physiochemical processes during H±Gd interaction.…”

Gadolinium nanoparticles, deposited via an inert gas evaporation method, show improved stability towards oxidation and it is therefore possible to carry out an ex‐situ investigation on “bare” Gd nanoparticles, i.e., in the absence of a protective Pd layer, for the first time. A size‐induced structural transformation from hexagonal close packing to the higher‐symmetry face‐centered cubic structure is observed. The important observation of hydrogen–Gd‐nanoparticle interaction at room temperature and atmospheric pressure, without a Pd catalytic layer, makes Gd nanoparticles a potential candidate for hydrogen‐sensing, switching, and storage applications.

“…The misfit strains were taken as 6% (resembling the formation of GdH 2 [34]) and 20% (resembling the formation of UH 3 [38]). The results in Table 2 show that the effect of the large displacements on the total strain energy is small and cannot cause a change in the preferred shapes.…”

“…It is widely known that nickel in powder form exhibits catalytic properties, especially in hydrogenation. It is thus possible that Ni plays the role of a catalyst in the formation of GdH 3 at low temperatures; so far this hydride was synthesized at temperatures much higher than room temperature [9,10]. On the other hand cobalt is rather inactive in reactions with hydrogen and this may be the reason of differences between final products after hydrogenation of Gd 3 Ni and Gd 3 Co; pure GdH 3 or a mixture GdH 2 and GdH 3 .…”
