Biosynthesis of the Fully Saturated C16 Homosesquiterpene Descartane Through Deprotonation With Cyclopropanation

Angewandte Chemie International Edition, EarlyView.
A non‐canonical C16 sesquiterpene synthase from Morganella morganii produces the unusual scaffold descartane. Its cyclisation mechanism was rationalised by isotopic labelling experiments and DFT calculations. Site‐directed mutagenesis altered enzyme function, resulting in alternative products, including voltairene, which requires a different ...

Pulsed‐Laser Ablation for the Synthesis of High‐Entropy Alloy Aerogels Toward H2O2 Production and Water Decolorization

Angewandte Chemie International Edition, EarlyView.
This work establishes a universal strategy for fabricating compositionally complex solid solution alloy aerogels via pulsed‐laser ablation and the sol‐gel process. The electrocatalytic capabilities of these aerogels are subsequently evaluated for H2O2 electrosynthesis and water treatment applications.
