Feed and Bleed Operating Mode for Electrochemical Flow Cells: Challenges, Solutions and Practical Insights

ChemElectroChem, EarlyView.
Continuous “feed and bleed” operation is introduced as a versatile alternative to conventional batch recirculation and single‐pass operation modes for electrochemical synthesis in flow cells. ‘Feed and bleed’ is demonstrated by electrochemical methanol oxidation to formate, showcasing its unique characteristics, which enable steady state operation with

The Interplay of Single Ion Anisotropy and Magnetic 3 d‐4 f Interactions in VIII2LnIII2 Butterfly Complexes

ChemistryEurope, EarlyView.
The 3d–4f coupling constants and relative angles between distinct anisotropy axes in butterfly‐shaped VIII2LnIII2 (Ln=Y, Tb−Yb) metal‐organic molecular complexes are determined using combined high‐field EPR spectroscopy and magnetisation studies. The observed chemical trend sheds light on the electronic exchange mechanism and highlights the important ...

Preassembly‐Controlled Radical Recombination at Bismuth: Decarboxylative C–N Coupling with Sulfonamides

Chemistry – A European Journal, Accepted Article.
Persistent transition metal radicals form the foundation for many metallaphotoredox protocols. Their ability to efficiently trap organic radicals and convert them into various coupling products has inspired the exploration of selective radical reactions even beyond the d‐block.

On the Facile Synthesis of Triazaarsoles Using Acyclic Precursors

Chemistry – A European Journal, EarlyView.
Easily accessible dichloroarsanes are suitable precursors for the synthesis of novel triazaarsoles, the arsenic analogues of tetrazoles and triazaphospholes. Our findings pave the way to access and fully investigate such aromatic arsenic heterocycles in detail.

Gas phase lubrication study with an organic friction modifier

Lubrication Science, Volume 35, Issue 1, Page 40-55, January 2023., 2023
Abstract Friction modifier additives play a crucial role in controlling friction and wear of lubricated tribological systems. Model experiments in a controllable atmosphere performed by integrating a tribometer into a system of in situ surface analytical methods in vacuum can give insights into the additives functionality.
