Diffundierter Sauerstoff als dominierender flacher Akzeptor in p‐Typ Kupferiodid‐Dünnfilmen  Diffused Oxygen as Dominating Shallow Acceptor in p‐Type Copper Iodide Thin Films 

open access: yesChemie Ingenieur Technik, Volume 95, Issue 11, Page 1786-1793, November 2023., 2023
Kupferiodid ist ein optisch transparenter p‐Typ‐Halbleiter mit relativ hoher Lochbeweglichkeit. Die Kontrolle der Sauerstoff‐Diffusion in dünne CuI‐Schichten ermöglicht die Steuerung der elektrischen Parameter, da Sauerstoff offenbar als flacher Akzeptor in CuI wirkt, in Gegensatz zu bisherigen Annahmen.

Automatisierte Generierung von Mikrokinetiken für heterogen katalysierte Reaktionen unter Berücksichtigung korrelierter Unsicherheiten**

open access: yesAngewandte Chemie, Volume 135, Issue 39, September 25, 2023., 2023
Der Reaction Mechanism Generator (RMG) wird zur automatischen Generierung eines Ensembles von Mechanismen für die Oxidation von Emissionen über Pt(111) verwendet. Durch die Auswahl von energetischen Parametern aus dem Unsicherheitsraum des BEEF‐vdW Funktionals entspricht jeder generierte Mechanismus einem anderen DFT‐Funktional.

MXene Free Standing Films: Unlocking the Impact of Flake Sizes in Microwave Resonant Structures in Humid Environments

open access: yesSmall, Volume 19, Issue 37, September 13, 2023., 2023
This work presents a comprehensive investigation of MXene films operating as microwave resonators under varying humidity. The effect of MXene flake sizes on the resonant performance under varying humidities is experimentally studied. To mitigate the power losses of MXene films upon degradation (e.g., humidity exposure), an active feedback configuration
