Chemical Ligation of Backbone N‐hydroxylated Peptides

Chemistry – A European Journal, EarlyView.
Peptide backbone N‐hydroxylation enables sequence‐agnostic fragment ligation via hydroxamate O‐acyl capture and O→N acyl transfer in water. Broad tolerance of sterically demanding nucleophilic residues is observed, and reductive N─O cleavage restores the native amide bond.

Utilization of Waste Materials Using the Müller–Kühne Process—A Life Cycle Inventory Study

Chemie Ingenieur Technik, EarlyView.
This study presents a Life Cycle Inventory of the Müller–Kühne process (MKP), which converts gypsum waste into sulfuric acid and cement clinker. The MKP outperforms conventional cement production regarding material yield, though its specific energy demand is higher. Consequently, potentials for circular gypsum waste utilization are discussed.

Structural and Electrochemical Evolution of Nickel Sulfides During Alkaline Hydrogen Evolution Reaction

ChemSusChem, EarlyView.
Post‐HER surface restructuring of nickel Sulfides (NixSy) through Sulfur leaching results in the formation of catalytically active Ni3S2, the most HER‐active nickel sulphide phase. The electrochemical activation process enhances hydrogen evolution performance while exhibiting self‐limiting behavior, ensuring long‐term catalyst stability in alkaline ...
