Unravelling the Mechanistic Pathway of the Hydrogen Evolution Reaction Driven by a Cobalt Catalyst
Angewandte Chemie, Volume 134, Issue 40, October 4, 2022., 2022 A CoI complex bearing a redox‐active κ‐N3P2 pentadentate ligand and its activity towards hydrogen evolution reaction is reported in this work. A combination of spectroscopic, electrochemical and computational techniques is employed to characterize the intermediate species, demonstrating an unusual homolytic coupling reaction pathway between two ...

Synthese von C60/[10]CPP‐Catenanen durch Regioselektive Nanokapsel‐Templierte Bingel Bis‐Addition
Angewandte Chemie, Volume 135, Issue 42, October 16, 2023., 2023 Die Kombination von drei Methoden (Tether, Nanohoop‐Template und supramolekulare Schattenmaske) ermöglichte die itero‐ und regioselektive Synthese von [2]Catenanen durch Bis‐Addition von Bis‐Bromomalonaten an den Komplex C60⸦[10]CPP. Die Verwendung einer „spurlosen“ Nanokapsel‐Schattenmaske war der Schlüssel für eine 87 %ige Selektivität für das „in ...

Synthesis of C60/[10]CPP‐Catenanes by Regioselective, Nanocapsule‐Templated Bingel Bis‐Addition
Angewandte Chemie International Edition, Volume 62, Issue 42, October 16, 2023., 2023 The combination of three approaches (tether, nanohoop template & supramolecular shadow mask) enabled the itero‐ and regioselective synthesis of [2]catenanes via bis‐addition of bis‐bromomalonates to the complex C60⸦[10]CPP. The use of a “traceless” nanocapsule shadow mask was key for obtaining 87 % selectivity for the “in,out‐trans‐3′′ product, where ...

The C‐terminal extension of VgrG4 from Klebsiella pneumoniae remodels host cell microfilaments
Proteins: Structure, Function, and Bioinformatics, Volume 90, Issue 9, Page 1655-1668, September 2022., 2022 Abstract Klebsiella pneumoniae is an opportunistic pathogen, which concerns public health systems worldwide, as multiple antibiotic‐resistant strains are frequent. One of its pathogenicity factors is the Type VI Secretion System (T6SS), a macromolecular complex assembled through the bacterial membranes.
