Green Hydrogen Production via Water Splitting Using SrFe <sub>0.9</sub> Mo <sub>0.1</sub> O <sub> 3− <i>δ</i> </sub> Perovskite as a Catalyst Open
Evidence of hydrogen production from water splitting using a nonstoichiometric cubic perovskite, SrFeMoO (SFMO), as a catalyst under moderate operating condition is presented. It is demonstrated that the SFMO oxide, when reduced at 800 °C …

Suppression of Elastic Scattering of CH<sub>4</sub> by Graphene Passivation of Ni(111) Open
We report high-resolution angular diffraction measurements of CH4 and Ne from Ni(111) and from a graphene (Gr) layer grown on Ni(111), whose effective atomic mass is enhanced by the strong Gr-Ni interaction. The incident energie…

Simulating high-pressure surface reactions with molecular beams Open
Using a reactive molecular beam with high kinetic energy ( E kin ), it is possible to speed gas–surface reactions involving high activation barriers ( E act ), which would require elevated pressures if a random gas is used.

Electron–phonon coupling in superconducting 1T-PdTe2 Open
We have determined the electron–phonon interaction in type II Dirac semimetallic 1T-PdTe 2 by means of helium atom scattering. While 1T-PdTe 2 is isostructural with 1T-PtTe 2 , only the former is superconductor. The difference can be trace…

Phonon dynamics of graphene on metals Open
The study of surface phonon dispersion curves is motivated by the quest for a detailed understanding of the forces between the atoms at the surface and in the bulk. In the case of graphene, additional motivation comes from the fact that th…
