The lack of suitable connectors for thin-walled carbon concrete elements withtheir known resource and material saving properties still represents a majorobstacle for practical application. On top, the on-site installation remains alabor-intensive tas

We employed an approach combining reaction kinetics measurements at steady state conditions, electronic structure calculations employing density functional theory, and microkinetic modeling for acetone hydrogenation to provide insights into the effec

Die Umsetzung einer modularen, vorgefertigten Bauweise sowie der weitreichende Einsatz von Leichtbauelementen aus Carbon- oder Textilbeton verlangen neue Verbindungselemente. Bauteile aus Carbonbeton werden wesentlich schlanker als vergleichbare Stah

The effect of strain on the adsorption of atomic species (Cl, H, N, and O) on pristine and nitrogen-doped graphene is studied using density functional theory. Expansive strain increases surface reactivity by destabilizing graphene π orbitals, which

We show that platinum displays a self-adjusting surface that is active for the hydrogenation of acetone over a wide range of reaction conditions. Reaction kinetics measurements under steady-state and transient conditions at temperatures near 350 K, e

Scaling relations are widely used to model catalytic reactions on metal surfaces, but they are less commonly applied to metal oxides. Oxygen vacancy formation energies have been suggested as a descriptor for the activity toward oxidation reactions vi

We study 14 transition metals on pristine and N-doped graphene using density functional theory. For double vacancies, nitrogen doping increases the binding strength of harder transition metals to t...
