Evolutionäre, funktionelle und mechanistische Charakterisierung mikrobieller Terpensynthase‐ähnlicher Gene aus Springschwänzen

Angewandte Chemie, EarlyView.
Eine Genomanalyse zeigte das Vorkommen zahlreicher Terpensynthasen des bakteriellen Typs in Springschwänzen. Vier Enzyme aus Sinella curviseta wurden funktionell charakterisiert, was zur Isolierung mehrerer Verbindungen führte, darunter Sinellenether, der erste identifizierte Diterpenether einer Terpensynthase mit einem neuartigen Grundgerüst.

CO‐Adsorption auf MgO in neuem Licht: polarisationsaufgelöste Infrarotspektroskopie identifiziert Stufenkanten als dominierende Defekte auf MgO(100) und MgO(110)

Angewandte Chemie, EarlyView.
Durch die Kombination von polarisationsaufgelöster IRRAS mit hybriden HSE06‐DFT‐Berechnungen ermitteln wir platzspezifische Schwingungsfingerabdrücke, Adsorptionsgeometrien und Bindungsenergien für CO auf MgO‐Oberflächen mit großer Bandlücke. Niedrig koordinierte Mg4c2+‐Stufenkantenplätze werden anstelle von Schottky‐Defekten auf Terrassen als die ...

Heavy‐Atom Tunneling at Room Temperature Revealed by Instanton Theory

Angewandte Chemie, EarlyView.
Usually, tunneling does not play a significant role in chemical reactions except at low temperature, especially when heavy atoms are involved. However, using nonadiabatic instanton theory we find that heavy‐atom tunneling dominates the reaction mechanism for spin‐forbidden processes in the synthesis of strained organic molecules even at room ...

Post‐Synthetic Zinc Modifications to Correct Speciation in Ti‐MWW Zeolites for Catalytic Oxidation

Angewandte Chemie, EarlyView.
Post‐synthetic Zn modifications of Ti‐MWW zeolite catalysts exhibit improved catalytic properties in the selective oxidation reaction, namely the ammoximation reaction. The origin of the beneficial effect of Zn is related via an array of spectroscopic and microscopic techniques to the modification of extra‐framework TiO2 and TiOx clusters and the ...

Key Drivers of Activity and Selectivity in Cu‐Based Catalysts for Methanol Synthesis From CO2: Insights From Atomically Dispersed Promoters

Angewandte Chemie, EarlyView.
Mechanistic studies on model Cu─M/SiO2 catalysts (M = Zn, Ga, and In) reveal that promoters enable a formate spillover pathway from Cu to Mn+ (n = 2 or 3) sites. The promoter's electronic effect on formate bond strengths serves as a quantitative descriptor for activity and selectivity, balancing spillover dynamics with intermediate stabilization to ...
