Update: Enzymatische Synthese für industrielle Anwendungen
Angewandte Chemie, EarlyView.Die Biokatalyse hat sich zu einer nachhaltigen und wettbewerbsfähigen Alternative zur herkömmlichen chemischen Synthese entwickelt und ermöglicht die enzymbasierte Herstellung nicht nur von chemischen Grundstoffen, sondern auch von (nicht natürlichen) Aminosäuren, (seltenen) Zuckern und synthetischen Nukleotiden.

Angewandte Chemie, EarlyView.Die Synthese von N‐heterocyclischen Olefinen (NHOs) auf der Basis eines Imidazo[1,5‐a]pyridin‐Gerüsts wird beschrieben. Während C5‐Alkyl‐ oder Aryl‐Substituenten stabile NHOs ergeben, induzieren Alkenyl‐ oder Alkinylgruppen an C5 eine 6‐endo‐Cyclisierung, um (Dihydro)imidazo[2,1,5‐de]chinolizine mit starken paratropen Ringströmen zu bilden.

Redirecting the Peptide Cleavage Causes Protease Inactivation
Angewandte Chemie International Edition, Accepted Article.Cysteine and serine proteases cleave peptides through covalent catalysis by generating a transient adduct with the N‐terminal part of the substrate after releasing its C‐terminal part. We demonstrate the unique redirection of this event leading to strong enzyme inactivation.

Angewandte Chemie, Volume 137, Issue 22, May 26, 2025.A continuous process for carbonylation reactions based on the online coupling of dry, high‐temperature CO2 electrolysis with a coil reactor has been reported. The strategy relies on producing CO/CO2 mixtures onsite, without H2 or H2O entering the product gas, thus providing a safe and fast concept for the synthesis of several carbonyl compounds.

Pulsed Electrochemical Exfoliation for an HF‐Free Sustainable MXene Synthesis
Small, EarlyView.Synthesizing MXenes using NaBF4/HCl and cathodic pulsing. This approach demonstrates the key role of cathodic pulse, which imposes bubble formation on the electrode, resulting in operando surface reactivation. Thus, the methodology demonstrates high‐quality HF‐free MXenes with up to 60% yield, paving the way for green industrialization.

Influence of environmental conditions on the creep behavior of large‐scale concrete specimens
Structural Concrete, EarlyView.Abstract In this article, a testing campaign on large‐scale concrete specimens to study the influence of environmental conditions on their creep behavior for different member sizes is presented. This testing campaign is unique due to its specimen dimensions (cross‐sectional areas of up to 1 m2) and the continuous deformation measurements for over 6 ...
