Directed Evolution of an Efficient Polycarbonate Depolymerase With Exceptional Operational Stability

Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.
Here, we show that well studied PET hydrolases can be re‐engineered via directed evolution to deconstruct alternative aromatic‐containing commodity polymers. Introduction of only three mutations into LCCICCG was sufficient to generate an efficient polycarbonate hydrolase with high operational stability that can fully depolymerize a polycarbonate sample

Molecular Mimics of Intermetallic Phases: Selective Alkylamide‐Ligand Deprotection Drives Co/Ga Cluster Formation

Angewandte Chemie International Edition, Volume 65, Issue 19, 4 May 2026.
The bimetallic M14 cluster [Co3Ga2]H(μ2‐GaTMP)9 was achieved by a co‐reductive approach utilizing Mg and H2 to selectively deprotect and capture the Ga‐TMP metallo‐ligands, forming a Co/Ga alloyed cluster kernel, making it a structural representative of a related solid‐state counterpart.
