A Predictive Model for Catalytic Methane Pyrolysis
Ulrich Pototschnig, Martin Matas, David Scheiblehner +4
Methane pyrolysis provides a scalable alternative to conventional hydrogen production methods, avoiding greenhouse gas emissions. However, high operating temperatures limit economi…
On energetics of allotrope transformations in transition-metal diborides via plane-by-plane shearing
Thomas Leiner, Nikola Koutná, Jozef Janovec +3
Transition metal diborides crystallise in the , , or type structure, in which pure transition metal layers alternate with pure boron layers stacked along the hexagonal [0…
-guided X-ray photoelectron spectroscopy quantification of Ti vacancies in TiON thin films
Pavel Ondračka, Marcus Hans, Damian M. Holzapfel +3
calculations were employed to investigate the effect of oxygen concentration dependent Ti vacancies formation on the core electron binding energy shifts in cub…
Graphene on silicon: effects of the silicon surface orientation on the work function and carrier density of graphene
Y. W. Sun, D. Holec, D. Gehringer +4
Density functional theory has been employed to study graphene on the (111), (100) and (110) surfaces of silicon (Si) substrates. There are several interesting findings. First, carb…
Enhanced fracture toughness in ceramic superlattice thin films: on the role of coherency stresses and misfit dislocations
Antonia Wagner, David Holec, Paul Heinz Mayrhofer +1
Superlattice (SL) thin films composed of refractory ceramics unite extremely high hardness and enhanced fracture toughness; a material combination often being mutually exclusive. W…
Point-defect engineering of MoN/TaN superlattice films: A first-principles and experimental study
Nikola Koutná, Rainer Hahn, Jakub Zálešák +6
Superlattice architecture represents an effective strategy to improve performance of hard protective coatings. Our model system, MoN/TaN, combines materials well-known for their hi…
