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 ...

(Bio)Functionalisation of Metal–Organic Polyhedra by Using Click Chemistry
Chemistry – A European Journal, Volume 29, Issue 60, October 26, 2023., 2023 Copper(I)‐catalysed alkyne‐azide cycloaddition click chemistry is a versatile post‐synthetic tool to functionalize the surface chemistry of alkyne‐functionalized cuboctahedral Metal–Organic Polyhedra (MOPs). This methodology enables quantitative functionalization of MOPs with a wide range of functional groups, including polymers, carboxylic and ...

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 ...

NMR in Biomedicine, Volume 36, Issue 2, February 2023., 2023 18O‐enrichment of liver glycogen, triglyceride glycerol, and blood glucose of mice given 18O‐water during overnight feeding was quantified by 13C NMR and MS. Glycogen 18O‐enrichment of oxygens 3, 5, and 6 from isotope‐shifted 13C signals informed indirect pathway contributions from different sources.

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.
