Hydrogen induced vacancy clustering and void formation mechanisms at grain boundaries in palladium
https://www.sintef.no/en/publications/publication/?pubid=1834903
Hydrogen has a significant impact on the formation of vacancies, clusters and voids in palladium and other metals. The formation of vacancy-hydrogen complexes in bulk Pd and at Σ3 and Σ5 grain boundaries was investigated using first-principles calculations and thermodynamic models. Equilibrium vacan...

Robust nanocomposites of a-Fe2O3 and N-doped graphene oxide: Interfacial bonding and chemisorption of H2O
https://www.sintef.no/en/publications/publication/?pubid=1714471
Nanocomposites of a-Fe2O3 (hematite) and (N-doped) graphene oxide (GO) were investigated using first- principles calculations with focus on structure, chemical bonding, electronic structure and H2O adsorption. The nanocomposites were modeled as the interface between the a-Fe2O3 (0 0 0 1) surface and...
