The dominant roles of “electron-density-mechanism” and “chemical-bonding-mechanism” for hydrogen in molybdenum and lithium

open access: yesNuclear Materials and Energy
Using first-principles calculations, we have systematically studied structures and thermodynamic stability of interstitial H as well as the H-vacancy interaction in molybdenum (Mo) and lithium (Li).

Unraveling the adsorption and diffusion behavior of H and O atoms at Zr(0001) surface doped with a Nb/Sn atom: A first-principles study

open access: yesHeliyon
With the formation of a surface oxide or hydride layer of the zirconium alloy, the ductility of the nuclear rod decreases obviously. Thus, it is significant to develop a deeply understanding of this process, which may assist in future corrosion and ...
